Mango (Mangifera indica) is one of the least professionally grown fruit crop globally. It is popularly known as ‘King of Fruits’ belongs to family Anacardiaceae. It is being cultivated for at least 4000 years (Crane, 2008). As per estimate total world mango production is 40 million tones.

Moringa oleifera Linn. belongs to the family Moringaceae, that consists of only one genus with about 13 species of deciduous trees (Keay, 1989). It is believed to be the native of India-Pakistan-Nepal borders, but now is becoming widely distributed and grown in several countries, particularly in tropical and subtropical regions (Satti et al., 2013).

Introduction

In recent years, inland saline aquaculture has emerged as a rapidly growing sector in the broader field of aquaculture due to the escalating pressure on traditional freshwater resources and the escalating demand for seafood. Saline aquaculture, cultivating aquatic species in inland waters with elevated salinity levels, presents opportunities and challenges. This chapter examines the innovations and challenges that characterize inland saline aquaculture, highlighting the urgent need for sustainable approaches that balance productivity with environmental resilience. The global population growth and dietary preferences have caused an increase in the demand for seafood (FAO, 2020).

This study aimed to optimize the incorporation levels of whole egg powder (WEP) and skim milk powder (SMP) and to evaluate the storage stability of the resulting protein-rich pasta. Response Surface Methodology (RSM) with a Central Composite Design was employed for optimization; thirteen formulation combinations were tested. The best formulation was identified as 5% WEP and 10% SMP. This optimal mix resulted in a significant improvement in the proximate composition of the fortified pasta compared to the control. Both the control and fortified pasta were stored under aerobic conditions at 20-30±5°C in aluminium foil-LDPE laminate pouches for 60 days. The pasta samples were analyzed at intervals of 1, 15, 30, 45, and 60 days. Storage studies revealed an increase in TBARS, FFA, peroxide values, and microbial counts in both pasta types, but the control samples exhibited a significantly lower rate of increase (p<0.05). Sensory evaluation showed lower scores for the fortified pasta compared to the control. Despite these findings, the fortified pasta with 5% WEP and 10% SMP maintained its physicochemical, colour, textural, microbiological, and sensory qualities over the 60-day storage period. Microstructure studies revealed increased interaction between added protein (WEP & SMP) and starch molecules, indicating a potential option to produce high quality pasta with enhanced nutritional and functional properties, thereby enhancing the practical implications of the research.

With the introduction of high yielding varieties and use of high analysis fertilizer in intensified agriculture under irrigation condition resulted in green revolution in our country. But continuous use of chemical fertilizer in indiscriminate manner without assessing soil also had adverse effect on productivity and environment. Though use of high analysis fertilizer ensured the high production but also resulted in acceleration of mining of native sources of nutrient. This has led to appearance of hidden hunger of several other essential nutrients and sustainability of our agriculture has become venerable.

Abstract

The landslide is a disaster which causes rampant loss to life, property and ecosystems. With increased awareness and technological development, the number of monitoring stations near hazardous regions have increased. To give warning prior to the occurrence of a landslide, the soil/rock mechanics of the underlying bed needs to be studied and understood. This paper examines the current literature and elucidates some features of state-of- the-art landslide monitoring systems.

Keywords: Field based sensors, Wireless sensor network, Landslide monitoring

INTRODUCTION

Advancements in technology have helped us to understand nature better than before, yet the geotechnical parameters causing landslides could not be quantified accurately. The efforts taken in predicting landslides are clearly moving towards this objective and this can be seen by the number of monitoring stations that have been setup in landslide prone areas around the world. The data that is obtained at each location is important in understanding landslides. Each location is unique in terms of soil properties, groundwater, inclination of the slope and weather conditions and consequently, each deployment is unique.

The paper narrates the instrumentation based forewarning systems functioning around the world. The paper discusses these aspects hierarchically viz; Landslide prone areas in India, geotechnical instrumentations and their merits, influence of rainfall on landslides, correlation between rainfall and pore pressure, the relevance of different systems for different scenarios etc.

Introduction

Genetic markers are genes or DNA sequences associated with a specific gene or trait, often arising from mutations or alterations in genomic loci (Samarai and Kazaz, 2015). Recently, there has been a growing interest in molecular markers, which reveal polymorphisms at the DNA level. These markers play a crucial role in animal genetics studies, as they help identify genetic resources and differences between domesticated and wild animals. Cytological markers, which use chromosome karyotypes, bandings, repeats, translocations, deletions, and inversions, are widely used for elucidating species origin and classification (Becak et al., 1971; Jonker et al., 1982).

6.1 Introduction

Water deficit stress is a serious and frequently encountered abiotic stress in the terrestrial surface. Its deleterious effects on plant growth and productivity are well documented. Plant responses to water stress are believed to be complex as these operate at various levels of plant organization. Several in built physiological and biochemical mechanisms provide resistance to plants against stress. An understanding of the processes linked to these mechanisms is vital for optimizing crop growth and productivity under stress. Plants respond and adapt to water stress by altering cellular metabolism, thus invoking stress tolerance. Alteration in endogenous concentrations of growth regulators along with accumulation of osmolytes, modifications in antioxidant cascade, changes in protein profiles and induction of gene expression in plants under stress are important characteristic metabolic changes that invoke stress tolerance at the cellular level. Alteration in endogenous concentrations of plant bio-regulators under stress helps plants through better turgor maintenance and efficient water usage by influencing stomatal functioning, hydraulic conductivity and morphological adaptation. Progress made in plant adaptation to water stress is an outcome of advances made in analytical techniques on endogenous growth regulator analysis and powerful and reliable molecular and genetic techniques.

Abstract

The potato research in India was started systematically after the establishment of Central Potato Research Institute (CPRI) in 1949. Forty-one potato varieties having attributes of early, medium and late maturity vis-à-vis resistance to various biotic and abiotic stresses have already been developed indigenously for varied agro-ecoregions in the hills and sub-tropical plains. After the establishment of CPRI, collection of potato germplasm was made mandatory. Presently there are over 2,700 accessions including 133 wild species (related to potato) in the germplasm collection of CPRI. Despite the large collection of potato germplasm at the institute the genetic base of all 41 Indian potato varieties released so far can be traced to only about 50 parents and most of these represent tetraploid potato cultivars while only a few of the exotic diploid wild species have been used in improvement of potato varieties in India. Under utilization of wild species could be mainly due to the pre- and post zygotic crossability barriers inherent in many species of genus solanum. Nevertheless, about seven wild species have been used in potato breeding for introgression of resistance genes for various biotic and abiotic stresses in the improved Indian potato varieties.

ENZYMES

Enzymes are the heart of Biochemistry

Protein based catalysts.

Enormously effective catalysts: typically enhance rates by 10⁶ to 10¹² fold.

Operate under mild conditions: 0 - 100 °C (or perhaps even 300+ °C for some bacteria in deep ocean), 20 - 40 °C for most organisms; and low pressures (atmospheric).

Very specific: Generally catalyze reaction for a very restricted group of molecules, sometimes for a single naturally occurring molecule of a single chirality.

Concept of Evaluation

Evaluation is the structured interpretation and giving of meaning to predict or actual impacts of proposals or results. It looks at original objectives, and at what are either predicted or what was accomplished and how it was accomplished.

Context Based Meaning and Concept

The meaning of evaluation is the way of judging or calculating the quality, importance, amount, or value of something: Evaluation of this new treatment cannot take place until all the data has been collected.

In its earliest uses (documented in the 15th century), context meant “the weaving together of words in language.” This sense, now obsolete, developed logically from the word’s source in Latin, contexere “to weave or join together.

7.1 Introduction

Water is one of the most essential natural resources of the planet. Water is also the most critical resource for sustainable development in most of the developing countries. The quantities that are needed for drinking and sanitation purpose of humans are relatively small, and much larger quantities of water are required for many other purposes. It is essential not only for agriculture, industry and economic growth of a country, but also it is the most important component of the environment and ecosystem, with significant impact on overall wealth and nature conservation. Agricultural and industrial activities critically depend on a sufficient amount of fresh water that is withdrawn from rivers, lakes and groundwater aquifers. Currently, the rapid growth of world population along with the extension of irrigation dependent agriculture, development of industrial sector and climate change are stressing the quantity and quality of the natural water systems. Due to the increasing problems, human have begun to realize that they can no longer follow “use and discard” methodology either with water resources or any other natural resources. As a result, the need for water management has become evident. Climate change has already started to affect the hydrological cycle and the availability of freshwater for agriculture. So, proper water management practices play crucial roles in the food production and the management of ecosystems. Over the last century global irrigated area has increased more than sixfold from approximately 40 million hectares in 1900 to more than 260 million hectares in 2000. Today more than 40% of the world’s food comes from the irrigated cropland which is 18% of the total cultivated crop land. Irrigated area is increased by almost 1% every year and the demand for irrigation water will increase by 13.6% by 2025 (Jensen, 1993). On the other hand about 8-15% of fresh water supply will be diverted from agricultural sector to meet the increased demand of domestic and industrial use. On the other hand the efficiency of irrigation is very low, only 65% of the applied water is used by the crop (Fig. 1). So, to overcome shortage of irrigation water for agriculture, it is essential to increase the water use efficiency in the crop field and to use marginal water for irrigation.

India achieved food security through the adoption of high-yielding seed varieties, chemical fertilizers to boost soil nutrition, and pesticides to protect crops. However, this progress came at an environmental cost, including excessive fertilizer use that harmed both human and ecological health.
Natural farming, or prakritik kheti in Hindi, represents a traditional yet evolving approach to agriculture that promotes ecological balance, self-reliance, and sustainability. It is deeply embedded in India’s agricultural legacy, where for centuries, farming was done without synthetic chemicals or mechanization. Today, it is gaining renewed importance as a viable alternative to input-intensive farming, offering solutions to challenges like soil depletion, falling groundwater levels, rising costs, and environmental degradation.
Natural farming operates on the belief that nature is inherently self-sustaining. It avoids the use of chemical fertilizers, pesticides, and GMOs, instead relying on natural, locally sourced inputs to boost soil health and crop yield. This method emphasizes collaboration with nature rather than domination over it. Subhash Palekar’s “Zero Budget Natural Farming” (ZBNF) model, based on low-cost and chemical-free techniques, has been especially appealing to small and marginal farmers.
Soil health is central to natural farming. Techniques like mulching with crop waste, applying jeevamrit (a fermented solution of cow dung, urine, and natural additives), and treating seeds with bijamrit are widely used. These enhance soil microbes and improve its capacity to retain water and nutrients. Natural farming also promotes biodiversity through intercropping, crop rotation, and the use of indigenous seeds.

V    :    Volt.

V domain    :    The variable region of the polypeptide chains of an immunoglobulin or T-cell receptor is composed of a single N-terminal V domain. Paired V domains form the antigen-binding sites of immunoglobulins and T-cell receptors.

Life cycle of nematode has six stages. The egg stage, first stage juvenile (J₁), second stage juvenile (J₂), third stage juvenile (J₃), fourth stage juvenile (J₄) and the adult stage.

The first four stages are the immature stages and are known as juvenile stages. The female lays eggs in soil or in plant tissues, singly or in groups as egg mass that hatch out into juveniles which are almost similar to adults appearance. The first moult occurs within the egg shell and the second stage juvenile comes out by rupturing the egg shells as J₂. In case of Xiphinema index, the juveniles are reported to emerge from the egg before the first moult. The juvenile cuticle is shed after each moult.

The egg

The nematode eggs are oval in shape. The eggs are covered by three membranes, the external protein layer which is the secretion of uterus wall, the middle chitinous layer or the true shell secreted by egg itself and the inner lipid layer (vitelline layer). The chitin content in the egg shell vary in different species of nematodes.

Kiwifruit (often shortened to kiwi outside Australia and New Zealand), or Chinese gooseberry, is the edible berry of several species of woody vines in the genus Actinidia (Lucas, 2003 and Stirk, 2005). The most common cultivar group of kiwifruit (Actinidia deliciosa ‘Hayward’) is oval, about the size of a large hen’s egg: 5–8 cm (2.0–3.1 in) in length and 4.5–5.5 cm (1.8–2.2 in) in diameter. In 2017, China produced 50% of the world total of kiwifruit.

Kiwi is among the very few recent introductions which have surpassed in popularity due to its tremendous commercial potential in the Sub Himalayan region of India. In fact, no other fruit has attracted so much attention in such a short period in history of commercial fruit production since 1960s. In India, Kiwi was first planted in the Lal Bagh Garden (1960) at Bangalore as an ornamental tree where bud bursting didn’t take place. Later on for cultivation purpose it was planted at IARI, Regional Station, Shimla (H.P.)

Introduction

With global population expansion, there is an increase in demand for high quality protein, especially from aquatic sources which have been achieved to some extent through enhanced management, nutrition, genetic improvement of production traits, disease diagnostics and therapeutics. The increasing role of aquaculture during the past decade has forced fishery managers to begin to address many problems associated with the intensive management of small populations. Any fishery operation which uses the limited number of broodstock fish for the production of next-generation can lead to a constriction in the gene pool of that population (Kincaid,1983).

Natural farming in India is deeply rooted in ancient agricultural traditions that prioritized ecological balance and sustainability long before chemical-based farming became widespread. Traditionally, Indian farmers relied on natural cycles, indigenous seeds, animal manure, and mixed cropping to maintain soil fertility, preserve water resources, and enhance biodiversity—principles that form the core of present-day natural farming.
The modern natural farming movement drew global inspiration from Masanobu Fukuoka, a Japanese farmer and philosopher who developed the “do-nothing” method. His philosophy advocated no plowing, no chemical use, and minimal human intervention, which resonated strongly with India’s Vedic agricultural practices. In India, Subhash Palekar further revived and adapted this approach into Zero Budget Natural Farming (ZBNF), a system using local materials such as cow dung, urine, and crop residues. ZBNF emerged as a grassroots response to the ecological damage and financial burdens caused by Green Revolution methods.
Natural farming has since gained international attention. Countries like South Korea, Brazil, and the Philippines have embraced similar ecological practices to address soil degradation and input costs. The FAO and other global bodies also support agroecological methods that mirror natural farming for sustainable food systems.

A silo is an airtight to semi-airtight structure designed for the purpose of preservation and storage of high moisture feeds as silage.
 
Role of the silo in silage making

Silo has only three functions in the ensiling process:
    1.    To provide a solid surface to permit compaction of the mass to eliminate air;
    2.    To protect the ensiled materials from air and water during the storage period;
    3.    Where desired, to aid in the removal of silage by providing a base for unloading equipment.
