Abstract

Apple productivity is declining gradually. It is the high time to find out new rootstock for apple improvement. The crab apples can play a pivotal role for the improvement of apple through proper utilization of their potentiality. A number of crab apples have been found growing wild in the Himalayas. Apple accessions collected from Shillong (Meghalaya) i.e. Malus baccata (Shillong), was found completely resistant to woolly aphid (Eriosoma lanigerum) and the development of root rot (c.o. Dematophora necatrix) and powdery mildew (Podosphora leuchotricha) was significantly delayed as compared to well known source of resistance, Malus zumi.  It has shown field resistance to apple scab (c.o. Venturia inaequalis) also.  It has a very good propagation potential.

For the first time, the Quality Planting Material (QPM) production from aerial stem node cutting and its comprehensive growth parameters are being reported in Valeriana jatamansi (Jones) (family: Valerianaceae), a highly endangered medicinal plant and a natural habitat in North Eastern Himalayan Region in the high altitude ranging from 1000 to 8000m Above Sea Level (ASL). The present communication identified a novel avenue exploring the unused plant part, aerial node cutting for producing QPM in a continuous and exponential rate without scarifying the rhizome and root, enriched with active ingredients like Valerenic acid and Valepotriates. This method also assures 100% plant emergence and more than 91±5.56% plant survival in the different field conditions without requiring hardening process as an additional merit. This first-time report for QPM production of an endangered medicinal plant, Valeriana jatamansi through aerial node cutting without following the hormone supplemented MS based tissue culture, a high cost process required sophisticated instruments and aseptic environment. This present process will have potentiality to explore commercially for mass clonal-propagation even at farmer level.

1. Introduction

The materials widely used for food contact applications include paper and coated-paper products, cellulose products, cellophane, metals, ceramics, glass, rubber, plastics, and miscellaneous materials such as wood, fabric, etc. Most of these materials have been in vogue for several years. Among them plastics are widely used in the food industry as they offer many advantages due to their high cost-to-benefit ratio. However, food safety issues in terms of migration of additives is a cause of concern. Plastics contain a number of additives either deliberately added during their manufacture or inevitable due to technical requirement.

ABSTRACT

A rapid micropropagation technique have been established for Solanum trilobatum L., a medicinal plant from internodal explant. Callus formation was observed from both cut ends of explants cultured on MS medium supplemented with 2,4-D (3.0 mg/l). Direct shoot and multiple shoot formation were noticed from explants (proximal cut end) on BAP (2.0 mg/l) alone and BAP (2.0 mg/l) + NAA (0.5 mg/l). Root formation was directly produced from the basal cut end of explants cultured on IBA (1.0 mg/l). In vitro plantlet regeneration has been achieved on BAP (2.0 mg/l) + IBA (1.0 mg/l). Regenerated plants were transferred to sterile vermiculite and soil mixture (3:1). In vitro propagated plants were grew successfully under the field conditions. In vitro propagation can be a useful tool for the conservation of this medicinal species.

ABSTRACT

Assessment of groundwater potential has wide importance in the exploration, management and development of groundwater resource. The fact that geologic and topographic factors, such as, geomorphology, lithology, structure, soil and slope control the occurrence and movement of groundwater in a region has been made use of in satellite remote sensing to aid groundwater exploration. In hard rock terrains, due to lack of primary porosity, lineaments have greater importance as those can be zones of secondary porosity trapping groundwater in its pore spaces.

In the present study, an attempt has been made to delineate groundwater potential zones in the hard rock terrain in the Gayatri River basin in Kerala, India, using satellite data. The study area which lies between 10o 26’N and 10o 45’N latitudes and 76o 21’E and 76o 54’E longitudes covering an area of about 1000 square kilometers is a drought-prone area. Landsat 7 ETM image of Gayatri River basin has been interpreted visually in a digital environment using ERDAS Imagine software to create geomorphology and lineament maps. Further, with the help of ancillary data, various thematic layers like, lithology, soil, drainage density, etc. have been created and subsequently updated using information obtained from the satellite data. Slope map of the basin has been created using Shuttle Radar Topographic Mission (SRTM) data. Integration of the thematic layers has been done in Arc/Info GRID GIS environment by giving weights to various thematic layers according to their importance in terms of groundwater occurrence. Finally, groundwater potential map of the basin has been prepared by classifying groundwater potential zones as good, moderate and poor.

Abstract

The East Coast of Tamil Nadu exhibits a spectacular network of deltas formed by the easterly flowing river systems. The study of raw and digitally enhanced Landsat TM and IRS data shows, that these deltas were formed due to multivariate dynamic processes of fluvial, marine and aeolian actions. The wide fan shaped delta observed northwest and north of Madras city spanning out over an area of 700 sq.km is a feature, standing testimony to the PaleoCauvery river systems.

The regional slope and the overall arcuate arrangement of the crescent shaped lakes in the area and the tentacles of paleochannels show, that it is overall a fan shaped delta and its successive growth towards the sea might have been due to the constant progradation of lobes by continuous reworking of preceding lobes. The depressions in between successive concentric lobes have become the lakes. The absence of any beach ridges in such palaeo deltaic regime suggests that, it would be a sub aerial delta only. The overall arcuate shape of the shoreline in between Madras city in the south and Pulicat lake in the north is due to this fan delta. This feature once again symbolises the active river dominated delta. The Palar delta is a ‘cuspate’ one. The Ponnaiyar river has developed a linear delta, along a narrow depression found in between Tertiary uplands. While the avulsion phenomenon indicates the ancient shoreline near Villupuram, the east-west trending micro sandy uplands within the delta suggest, that it is a tide dominated delta.

Introduction

A biopolymer is defined as a polymeric substance obtained from any living organism (plant or animal) [1]. These polymers are organic compounds where simpler molecules are covalently bonded with each other [2]. Although biopolymers are strictly synthesized naturally by living cells but some of them are also synthesized from non-biomaterial as well. Natural biopolymers are of different types based on their chemical nature like carbohydrate based, protein based or lipid based. Biopolymers can be broken down by the action of naturally-occurring organisms which leaves organic non-harming by-products like water and carbon dioxide in the environment[3].

Bio polymers are gaining importance in the field of food packaging, medical application, commodity packaging etc. because of their have specific physical, chemical, biological, biomechanical and degradation properties. Wide ranges of natural or synthetic biopolymers capable of undergoing degradation hydrolytically or enzymatically are being investigated for many applications[1]. Bio polymers are mainly based on two properties: a) Biological origin b) Biodegradability.

Earlier natural biopolymers such as cellulose, protein, starch have been used extensively for food applications. Recently, synthetic biopolymers such as polylactic acid (PLA), polycaprolactone (PCL), polyglycolic acid (PGA), polyvinyl alcohol (PVOH), and polybutylene succinate (PBS) are gaining more attention[4] for various applications. Natural biopolymers are more stereospecific and mostly hydrophilic having complex 3D structures as compared to the synthetic polymers[2]. Among the synthetic biopolymers some are microbiologically degradable in the environment whereas some are recyclable[1].

Introduction

Because of their incredible diversity of life and amazing distinctiveness, coral reefs are frequently referred to as the "Tropical Rainforests of the Sea". Reefs are vast biological treasure troves that provide millions of people throughout the world with a variety of economic and environmental services. Corals are useful and beautiful things that are members of the phylum Anthozoa. The massive reefs that are only visible at low tides are built by hermatypic corals and their symbiotic zooxanthellae. Corals are only found in the ocean and, taxonomically speaking, are part of the scleratinia order.

The solitary forms, known as ahermatypes, are both solitary and colonial and lack symbionts. Corals that form reefs are actively growing in the ocean's photic zone. Around the world, a belt of coral reefs can be seen in the tropical waters. Coral reefs are of immense importance, but due to both natural and man-made influences, they are rapidly degrading and disappearing at an alarming rate. By 2030, 90% of the reefs would be in danger if current rates of erosion are permitted to continue. It is crucial to comprehend the coral reefs' current state of health and the growing dangers to them. The study's goals are to examine management and conservation strategies and shed knowledge on the expanding issue of coral exploitation (Jhajhria, 2021).

The Cladocera, commonly known as ‘waterfleas’ form a primitive group of microcrustaceans. They play an important role in the aquatic food chain and also contribute significantly to the zooplankton dynamics and secondary productivity in freshwater ecosystem. Though most cladocera is filter feeders, they also feed on detritus, algae, small rotifers and copepod nauplii. They keep a check on eutrophication for which this group is also widely used as good indicators of ecosystem health and sentinels of environmental change (Eggermont and Martens, 2011; Padhye and Dahanukar 2015). At the same time, cladocera is the favorite food prey of many invertebrates and many vertebrates. Their characteristic jerky movements make them easily visible to the predators and that is why most of fish larvae were found to prefer cladocera over the prey (Mayer and Wahl,1971).

Cladocerans have a distinct head, a single compound eye, and a large mandible for grinding food particles. Cladocerans feed on algae, small rotifers, and copepod nauplii. Cladocerans reproduce mostly asexually via parthenogenesis. But they can also reproduce sexually based on the environmental conditions.

The distribution of cladocerans is affected by different factors including temperature, rainfall, water quality, nutrients, macrophytes, flood pulse etc. (Ghidini et al.,2009; Kiss et al., 2014). Their metabolic rate is variable with water temperature.

The order cladocera belongs to the subclass Branchipoda and includes minute crustaceans generally in the size range of 0.2 to 5.0 mm.

INTRODUCTION

The Food and Agriculture Organization (FAO) of the United Nations defines aquaculture as the cultivation of aquatic organisms such as fish, mollusks, crustaceans, and aquatic plants by individuals or corporations. In aquaculture, interventions are made in the rearing process to enhance production. While aquaculture is a practice with origins dating back more than 3000 years, Aquaculture products have only recently been recognized by the United Nations Statistical Commission as distinct global commodities, despite the practice having origins dating back more than 3000 years. According to the FAO's "Global Aquaculture Production" database, the annual global production of aquaculture has increased at an average rate of around 8% over the past three decades (since 1980). Despite a recent slowing in global trends, growth remains higher than any other major animal food production sector. This rapid global increase in production is occurring alongside a slow decline in marine fisheries catches. There is a growing global focus, largely driven by demand from Western countries, on increasing the intensive production of omnivorous and carnivorous species farmed and harvested in maritime and brackish coastal environments, a practice known as mariculture. The farming of these species, such as salmon, groupers, seabasses, and prawns, typically relies heavily on inputs such as wild post-larvae and juveniles, fishmeal, fish oils, as well as significant amounts of water, land, and energy. As a result, mariculture has faced widespread criticism due to its often negative impacts on marine and coastal ecosystem health. Negative associations have been drawn between mariculture and its effects on marine capture fisheries and food security.

Introduction
Aquaculture is one of the food-producing industries with the fastest rate of growth in the world and is widely recognized for its substantial contributions to food security, revenue production, and poverty alleviation (Subhasinghe, 2003). The production of aquaculture has increased dramatically during the last 30 years, from less than 20 million tonnes in the early 1990s to 178.9 million tonnes in 2022. The aquaculture industry reported an average growth rate of 6.7% per year globally from 1990 to 2020 (FAO, 2022). In 2020-22, the global annual per capita fish consumption was 20.4 kg (FAO, 2022). In addition, 58.5 million people were engaged in this sector worldwide for their livelihood. Many new approaches and technologies have been developed to increase the production. However, aquaculture faces significant challenges, including environmental quality, quality seed availability, and disease management (Sitcha et al., 2020; Oglend, 2020). To address these issues, the aquaculture industry adopts new scientific and technological advancements. Among the recent advancements in science, nanotechnology is fast emerging as a novel tool for the next generation of aquaculture and fisheries development. Nanotechnology is rapidly becoming a new tool for the growth of aquaculture and fisheries in the next generation, among other recent scientific breakthroughs
(Shah et al., 2020).

Introduction

In shrimp farming practice, the production cost of shrimps mainly depends on the feed cost and its associated water quality management issues. Hence, the success of shrimp aquaculture is wholly depends on the feed input cost and this feed cost involved can be reduced to a greater extent by enhancing the organic productivity of the ponds, particularly by enhancing the plankton productivity, which include, the assemblages of phytoplankton and zooplankton.

Abstract

The best way to conserve the biological diversity is by involving the local community. It is popularly known as community-based biodiversity conservation (CBC). The conflict between the nature and local communities who have stakes and rights in their territory is a matter of great concern. Likewise, when there prevails the community diversity, what would be the role, participation, share, stake, management issues, equity parameters etc. are the factors that affect CBC. However, CBC is future of conservation of natural resources. It needs adequate focus of community-scale projects on biodiversity conservation implemented by different parties and NGOs. Similarly, empowering community people through adequate financial support and appropriate monitoring and evaluation are the key success factors of community conservation projects. Ethnicity, gender and wealth were the factors that predicted CBC. Hence, the CBC programmes must address these aspects with adequate emphasize. The conflict between human activity and biodiversity conservation, if handled very effectively, will be a productive strategy to highlight pragmatic problems that arise at the field level and creating equitable and sustainable solutions. The general threats as a result of conflict between human activity and biodiversity conservation are agricultural intensification, recreation and human activities and policy related threats. Hence, awareness creation must have an integrative and interdisciplinary approach including the bodies that administer social and natural movements as well as the interests and priorities of local communities. Governing biodiversity conservation measures through political processes by engaging the appropriate representatives has valid implications for the whole process of biodiversity conservation. Alienation of local community, lack of favorable legal framework and lack of addressing the conservation issues through political process may adversely affect the biodiversity conservation as a whole.

Abstract

Cyanobacteria, the Gram-negative photosynthetic prokaryotes are able to produce a wide range of secondary metabolites. Some of these metabolites are of general concern due to their toxicity and known as cyanobacterial toxins. These cyanotoxins are reported widely due to human and animal health hazard. On the basis of their toxicological target, these cyanotoxins can be classified into five different groups: hepatotoxins, neurotoxins, cytotoxins, dermatotoxins and irritant toxins (lipopolysaccharides). Hepatotoxins constitute a family of cyclic peptide variants and are classified as microcystins and nodularins. These hepatotoxic peptides possess a high degree of cellular specificity to the hepatocytes with similar mode of action and act as potent inhibitors of protein phosphatases 1 and 2A (PP1 and PP2A).

With an advancement of technology, new gadgets are flooding the Indian market continuously bringing an immense opportunity for the education sector to improve upon the course delivery system. Higher education sector in India is adopting such new technologies in course delivery at a slow pace; however, there remains still a far way to traverse for the Indian education sector in order to achieve a perceptible and effective technology-infusion in the academic delivery arena. This paper is devoted to present an expository review on the usefulness of new gadgets, like smart phones, e-book reader as well as tablet PC, in both class-room education-delivery segments as well as in distance education sector in India.

Introduction

India is an agriculture-based country and it contributes most to the economy of the country. Different types of crops are cultivated in a wide range in different ecological regions based on different seasons. So, crop residue is also generated in an extended way by cultivation (Devi et. al 2017). Crop residue is the left over part of the crop after harvesting. In India, crop residue generates around 600 Mt and from which cereals are 70%, fibres 13%, oilseeds 6%, pulses 3%, sugarcane 2%, and others 6% (Jain et al., 2014). Corn production has increased more than 15 times from 1950-51 to 2016-2017. Rice, wheat, millet, barley, and maize are important cereal crops in Uttar Pradesh (Roy and Ahmad, 2015). Traditionally, Crop residue was used as cattle feed, animal bedding, cooking fuel, organic manure, etc. and some residues were used in making handicraft products by rural women. but still, a huge amount of residue is left without management and farmers have no option left except to burn it. About 90 to 140 Mt of crop residue burning in the field or households as fuels (Jain et al., 2014). In the process of harvesting and threshing, residues are left behind in the f ield. Farmers need to clear their fields early for the planting of the next crop so they do have not enough time and it is tough to clear the field at that time. Therefore, the farmers opt for the burning of residue in harvested fields due to a lack of access to user-friendly, cost- and time-effective options. The burning of crop residue creates many issues and effects on the environment and health badly. In a report of NAAS in 2017, it was estimated that in November 2016 at the period of rice residue burning, the NASA satellite images showed the intensity of rice residue burning in Punjab, Haryana, Western Uttar Pradesh, and Uttarakhand was very high. It is doing an additional job of increasing air pollution with vehicles, chimneys, industries, etc. Crop residues release many gases by burning them and these gases are contributing to global warming.

2.1 Overview of the CDM Project Cycle

The ultimate governing body of the CDM is the Conference of the Parties/Meeting of the Parties to the Kyoto Protocol (COP/MOP). The COP/MOP is the annual meeting of the signatories to the Kyoto Protocol and is responsible for managing the CDM Executive Board and for overseeing its work. The Executive Board supervises the CDM process under the authority and guidance of the COP/MOP; it is fully accountable to the COP/MOP. The Board decides on rules for the implementation of the CDM, as well as making the final decisions about acceptance of methodologies, registration of projects and issuance of CERs. The Board is composed of 10 members and 10 alternates. The CDM Executive Board created an A/R Working Group to specifically oversee LULUCF under the CDM. The A/R Working Group provides guidance to LULUCF project developers and, using expert reviewers, makes recommendations on acceptance or rejection of LULUCF methodologies.

Introduction

Pulse production in India has fluctuated widely with no long-term trend, leading to a steady decline in per capita availability per day, i.e. from 60.7 grams to 33.40 grams during 1951 to 2001, while its average requirement is about 65 gram per day per head. The pulses used to serve a low cost food to meet the protein requirement of a large sector of people in India. But, the pulses are becoming out of reach for the common people of country because of its continuing shoring prices. A Technology Mission on Pulse production was launched by Government of India in 1986-87 as a special drive to increase the pulse production in the country. The vision of Technology Mission of Pulse is attaining self reliance in pulses for household nutritional security and sustainability of the production system. The mission statement was to increase Pulse production from existing (IX plan) 131.4 lakh tonnes to 162 lakh tonnes; Productivity from 594 kg/ha to 702 kg/ha and per capita availability of pulses from 35 g to 40 g per day at affordable price. Unfortunately, the country has not been able to achieve self-sufficiency in the pulse production. During the last 40 years, the acreage under pulse crops and its production remained almost between 21-24 million hectares and 10-15 million tonnes, respectively. Consequently, the country has had to depend on import of pulses every year to meet the part of its shortage. The National Commission of Agriculture had estimated that the country should plan to produce about 25 million tonnes of pulses by the end of 2000, but we could achieve only about 14 million tonnes. Presently, the area and the production of pulse crops account for about 18.50 and 7.20 per cent (2003-04) of total area under foodgrains and total food grains production in the country, respectively.

ABSTRACT

The present study was carried out to assess the knowledge level of dairy Entrepreneurs of Patna District and to find the co-relation between the socioeconomic variables and the training needs. This study was conducted by personally interviewing 100 dairy farmers, sent for training at B.V.C. Patna by different Agencies. Majority of the respondents (58.20%) had medium level of knowledge flowed by 26% respondents with high level of knowledge, while some of the respondents (15.80%) had low level of knowledge about dairy entrepreneurship. The study of co-relation between socio-economic variables and training need of the respondents showed that variables like education (0.469), social participation (0.500) and the knowledge (0.734) were significantly and positively co-related with the training need. Whereas variables like age (0.063) family size (0.193) and land holding (0.072) were found to be positively but non-significantly co-related with the training needs while, the caste (-0.093) was found to be negatively and non-significantly co-related with the training needs at 0.05% level of probability. Therefore it is imperative on the part of change agency to utilize the variables gainfully so as to give needed push to knowledge level in the area of Dairy entrepreneurship development.
