Edible bananas are classified into several main groups and subgroups. In the first place is the diploid M. acuminata group which originated in Malaya, Indonesia, the Philippines, Southern India, East Africa, Burma, Thailand, the West Indies, Colombia and Brazil. This group is characterized by dark-brown sheaths of pseudostem,  and the leaves are nearly free from wax. The bunches are small and the fruits small, thin-skinned and sweet. Cultivars of this group are more important in New Guinea than any where else. Lady Finger which was popular in Queensland and New South Wales belonged to this group.

In second place, there was a group represented by the prominent and widely cultivated ‘Gros Michel’ originally from Burma, Thailand, Malaya, Indonesia and Ceylon. It was introduced into Martinique early in the 19th Century by a French naval officer and, a few years later, was taken to Jamaica; from there it was carried to Fiji, Nicaragua, Hawaii and Australia, in that sequence. It is a large, tall plant bearing long bunches of large, yellow fruits, and it was formerly the leading commercial cultivar in Central Africa, Latin America and the Caribbean, but has been phased out because of its great susceptibility to Panama disease. It has given rise to several named sports or mutants (Mortan, 1987).

Abstract

India is primarily agrarian country and this sector provides livelihood to a major part of the population. The indiscriminate use of agro chemicals since green revolution resulted in adverse effect on the soil fertility; crop productivity; quality of produce and more specifically on the environment system. Organic cultivation is the form of agriculture that relies on techniques such as crop rotation, green manure, compost, and biofertilizers which helps to maintain soil productivity. Organic farming excludes or strictly limits the use of chemical fertilizers, pesticides (herbicide, insecticides and fungicides), plant growth regulators, livestock feed additives, antibiotics and genetically modified organisms. Thus, the importance of organic sources of nutrients was recognized in current scenario in order to get higher yield without disturbing soil health. In this context integrated use of inorganic and organic sources of nutrients in crop production is becoming very crucial for assurance of food security on sustainable basis, which in turn not only improve the soil fertility for sustained crop productivity but also to reduce the cost of inorganic fertilizers.

INTRODUCTION

Persian walnut (Juglans regia L.) is of great importance across worldwide where nuts are harvested from wild stands, backyard gardens and rarely from commercial orchards that vary considerably in their size and degree of management. Nuts are collected for home consumption, sale at local roadside stands and markets and for shipping to cities. Walnut trees are further utilized for their high quality timber to make a wide array of products. The leaves, bark and other plant parts are used for medicinal remedies and trees are grown and maintained for soil conservation purposes (Mamadjanov, 2006b). A diverse mix of seedlings, local selections, and advanced cultivars are grown for nut production, many with unknown origins, including some of which are the direct result of selection from the wild.

INTRODUCTION

Water is one of the most important inputs essential for tree growth, development and fruit production. Fruit trees need it continuously during their life in optimum quantities. It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients, and cell division besides some other processes. Both its shortage and excess affect the growth and development of a plant directly and, consequently, its yield and quality. In India, however, rainfall is notoriously capricious, causing floods and droughts alternately. Its frequency distribution and amount are not in accordance with the needs of the particular fruit crops. Artificial water supplies through irrigation on one occasion, and the removal of excess water through drainage on another occasion, therefore, become imperative, if the fruit crops are to be raised successfully. Water management in India, thus, comprises irrigation or drainage or both, depending considerably on the environmental conditions, soil, crops and climate. Applying the proper amount of water at the right time is important for reducing costs and maximizing profits. It is essential, therefore, that there be a scientifically sound method for determining when to irrigate and how much water to apply for optimum crop response and efficient use of resources.

Introduction

In the environment of dwindling water resources and contention of the other sectors, the share of water allocated to irrigation is likely to be decreased by 10 to 15 per cent in the next two decades. One of the ways of improving water scarcity is by enhancing its use efficiency or productivity. Water use efficiency (WUE) is a broad concept that can be defined in many ways. For farmers or farm irrigators, WUE is the yield of harvested crop produce achieved from the available water to the crop from irrigation, rainfall and soil water storage. Improving WUE in pomegranate will be required an increasing in pomegranate water productivity (i.e. an increasing marketable yield per unit of water used by plants and reduction in water losses from the root zone (Chopde and Gorantiwar, 1998; Chopde et al., 2001; Intrigoli et al., 2011). For comprehensive improvement of WUE, it is necessary to raise the following ratios to their maximum: stored soil water content/water received through rainfall and irrigation, transpiration/water consumption, biomass yield/transpiration, water consumption/soil water storage and economic benefit/biomass yield (Frederick, 1993).

Abstract

On the basis of symptoms, samples from seven localities within Solan district (H.P.) at varying altitudes ranging from 600-1650mts comprising Nalagarh (600-750m), Badghal (850m), Dilchab (950-1000m), Shaya (1200m), Solan (1300-1450m), Bajhyana (1520m) and Tikari Pajahali (1650m), were collected and used for serological detection by DAS ELISA. It was found that all the isolates except Nalagarh, reacted positively with the antisera to ToLCV, thus substantiating the results on the identity of the present isolates. Out of the seven isolates under study, Dilchab and Shaya isolates did not show any PCR amplification for Rep gene indicating the variability in the regions flanking the Rep gene. Likewise, no amplification result in case of Nalagarh sample proposes the attack of some other pathogen producing similar symptoms.

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.

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.

Abnormal milk: It is milk that is not smooth and homogenous but is flaky, ropy, stringy, slimy, watery, discoloured or bad flavoured (Plate 1 & 2).

Abrassive peeler: It is equipment comprising a rotating drum lined with carborandum (an abrasive material) in which certain vegetables like potato and ginger are tumbled and exposed to the abrasive action of the carborandum lining, thereby facilitating separation of peel from the vegetables (Plate 3).

Absinthe: It is green liqueur which is flavored with wormwood, anise, and other aromatic herbs (Plate 4). Its commercial production is banned in ma ny countries for health concerns.

Absolute alcohol: It is water free alcohol. It contains atleast 99 per cent pure alcohol by weight and obtained by digesting rectified spirit over quicklime and redistilling the same.

Absolute density: It is the ratio of weight of certain volume of a substance at 1oC to that of weight of same volume of water at 4oC.

Absolute humidity: Absolute humidity is defined as kg of water vapour per kg of dry air at a given temperature and pressure. Absolute humidity is the mass of water vapour divided by the mass of dry air in a certain volume of air at a specific temperature. The warmer air absorbs more water than cooler one. Absolute humidity is the measure of water vapour or moisture in the air, regardless of temperature.

Absolute pressure: It is equal to atmospheric pressure minus vacuum pressure (Plate 5).

Absolute zero: It is a theoretical temperature characterized by complete absence of heat and motion and equivalent to exactly -273.15°C or -459.67°F (Plate 6).

Okra (Abelmoschus esculentus Moench), known in many English-speaking countries as lady’s finger or gumbo, belongs to family Malvaceae. The geographical origin of okra is disputed and supposed to be South Asian, Ethiopian and West African origins (Anonymous, 20013a). Its proposed parents are reported to be in South Asian; therefore, it is believed that perhaps it is of South Asian origin. However, because of greater diversity in okra in West African region, it is considered to be originated in West Africa. Masters (1875) proposed that it originated in India.
Okra is cultivated in tropical, subtropical and warm temperate regions, including the Middle East, Africa, Brazil, Turkey and southern states of USA (IBPGR, 1990; Jideani and Adetula, 1993; Acquistucci and Francisci, 2002). In tropics it is cultivated during summer and in the warmer parts of the temperate regions. It is an annual or perennial plant, growing up to 2 m height. The leaves are 10–20 cm long and broad, palmately lobed with 5-7 lobes. The flowers are 4–8 cm in diameter, with five petals which are generally yellow, but often white with a red or purple spot at the base of each petal. The fruit is a capsule which may attain length up to 18 cm containing numerous round seeds. Okra is an allopolyploid of uncertain parentage (proposed parents include Abelmoschus ficulneus, A. tuberculatus and a reported “diploid” form of okra).

Abiotic stresses include salinity, drought, flood, extremes in temperature, heavy metals, radiation etc. They are the foremost factors that causes the loss of major crop plants worldwide. This situation is going to be more rigorous due to increasing desertification of world’s terrestrial area, increasing salinization of soil and water, shortage of water resources and environmental pollution.

The inadequacy of water availability, including precipitation and soil moisture storage capacity, in quantity and distribution during the life cycle of a crop to restrict the expression of its full genetic yield potential”. Generally drought stress occurs when the available water in the soil is reduced and atmospheric conditions cause continuous loss of water by transpiration or evaporation. Drought stress tolerance is seen in almost all plants but its extent varies from species to species and even within species.

Chemicals which are used specifically for the control of mite pests are known as acaricides, though there are many insecticides, which show acaricidal properties as well. In the last few decades, there has been tremendous progress in the development of broad-spectrum acaricides i.e. the compounds that will knock down different species of mites at the same time. Prior to the commercial introduction of broad-spectrum insecticides like DDT and other organochlorine insecticides, mites did not commercially cause wide-spread damage under natural or semi-natural environments which were little influenced by man. This might be due to the natural processes of prey-predator relationship in undisturbed situations. Contrastingly in situations where broad-spectrum pesticides are commonly used, the natural enemies are more adversely affected than the mites, and an outbreak of the latter occurs. Besides becoming generally intensified with the introduction of modern insecticides, the mite problem in some cases has subsequently become even more serious due to development of resistance against these materials.

Many spider mite species, which were rarely found in pest form in some situations, appeared commonly as major pests with the persistent use of pesticides. In Indian literature, spider mites were never reported in pest form prior to 1940 but with the intensive use of pesticides, every year new mite problems are appearing and becoming troublesome to control.

When avoidance or tolerance of frost is not possible and frost damage is inevitable, the active methods of frost protection are the way out for the protection of the fruit plantations. The methods which are employed just before or during a frost event for avoiding freeze damage are called Active Frost Protection Methods.

Abstract

Temperate fruit production in India is mainly confined to the Himalayan region particularly in north-west states namely J&K, HP and Uttaranchal and to the east in Arunachal Pradesh.Though these areas are sparsely populated, yet are the main centers for production of these fruits. Apple is the leading cash fruit among these fruits occupying nearly 85.0 per cent of the total area 90 per cent production under these temperate fruits.

The apple cultivation in these states is more than 100 years old where the English settlers planted acidic types varieties in Kullu, Shimla, Chaubattia and Kodikonal hills. Quality Delicious apples which were introduced by an American Missionary Samuel N.Sokes in 1917 at Kotgarh, form the today’s commercial apple production in H.P. exception Kashmir valley, temperate fruit production in India is in temperate type of climate available in these states due to higher hills experiencing adequate winter cold and snowfall.

3.1 Technology assessment - A pillar of innovation commercialization
The process of transitioning an innovative technology to commercial reality requires a stringent and formal process known as technology assessment. This early stage is crucial as it determines the viability of an invention by analysing practicability of the invention as well as its uniqueness and the likelihood of it being adopted in the target markets. In the absence of this preliminary examination, the chance of technology’s potential being mismatched to the market can arise.
a) Scientific merit and technical feasibility
A key benchmark in assessing technologies involves the identification of
scientific validity and technical performance. An innovation’s viability depends on the fact that it complies with good scientific practice or the innovative application of a new paradigm that has empirically confirmable validity. It is important to determine whether the invention’s underlying mechanism can be reliably proven through established scientific practice. A working prototype allows for empirical testing in different conditions and serves as proof of practical application. In addition to that, scalability has to be tested critically. It often happens that innovations perform well in a controlled laboratory setting but lose efficiency or cost-effectiveness in the case of mass production. The viability of the implementation on a grand scale becomes a core concern in this phase of the evaluation.

1. Introduction

Food is an essential requirement for survival. We work hard to earn money so that we can feed ourselves. However, at the end of the day, many of us are unsure about the quality of food we consume. The allure of money, along with a general disregard for humanity, has resulted in the addition of adulterants to food ranging from simple stones in rice to the more harmful chemicals in food of daily use. Surprisingly, food fraud is not a modern issue. There are several references to fraudulent food behaviour as early as the Romans, but it is usually considered to be the Victorian who places food fraud on the map.

Introduction

Fruits and vegetables are an important part of healthy human diet. Consumption of vegetables is widely promoted by Governmental health agencies since it provide consumers essential nutrients such as vitamins, minerals, dietary fiber and phytochemical compounds, at a relatively low calorie density. Furthermore, the consumption of vegetables has been strongly associated with reduced chronic and degenerative diseases such as cancer and heart related ailments. The United States Department of Agriculture recommends five to nine servings of fruits and vegetables daily (Berger et al 2010). In recent years, fresh-cut produce has become more popular due to their convenience, freshness, taste and assumed “Healthiness”.
