Precision farming is one of the most scientific and modern approach to sustainable agriculture. It involves management of within field variation and helps farmers to grow crops more efficiently. Precision farming is concerned with the management of variability in the dimensions of both space and time. Variability of resources is a key factor of precision farming.   Precision farming is the application of technologies and principle to manage spatial and temporal variability associated with all aspects of horticultural production for improving crop performance and environment quality. Precision farming calls for an efficient management of resources through location specific hi-tech inventions to produce cost-effective and eco-friendly consumer- acceptable quality products (Mondal and Tewari, 2007).

The development of bio-informatics started with the working of computers and accumulation of data on genes and proteins. There are 100,000 proteins in the human body or 1 million. In the last decade the number of protein sequences gathered in databases increased tremendously, but the key to understand the function of a protein is not its sequence but its structure. Experimental determination of 3 dimensional native folded structure of a protein usually can be done via crystallography techniques. But such experiments are time consuming. Currently there are hundreds of different fully automated approaches to protein 3D structure prediction.

All proteins are polymers of Amino acids. The polymers also known as polypeptides consist of a sequence of 20 different L-m-amino acids also referred to as residues. For chains under 40 residues the term peptide is frequently used instead of protein. To be able to perform their biological function, proteins fold into one that is driven by a number of non covalent interactions such as hydrogen bonding, ionic interaction, Vander Waal’s forces and hydrophobic packing. In order to understand the functions of proteins at a molecular level, it is often necessary to determine the three dimensional structure of proteins. The modern Information Technology techniques like Artificial Intelligence have opened new pathways to researchers. Once ANN has been trained it is capable of producing accurate output for the unknown inputs. Many researchers have tried to analyze the large sequence sized gene to determine the protein, predict the secondary structure of the protein and model its three dimensional (3D) view [11].

Abstract

A Mathematical Method for Artificial Neural Networks offers an original, broad and integrated approach that explains each tool in a manner that is independent of specific ANN systems. Artificial Neural Networks are abstract mathematical models of brain structure and functions. They are nothing but a mathematical model that relies on varying the strength of connections between the internal processing elements to interpret data. They can be applied to many pattern classification problems. In this paper, it has been used to predict the level of amino acid in protein sequences. Amino acids are the building blocks of proteins. It is any molecule that contains both amine and carboxylic acid functional groups. Here, known protein sequences of ingredients are taken as input patterns. The network is trained using back propagation algorithm with sigmoid function as activation function by generating random weights. It is tested again with unknown protein sequence. Error is calculated by the difference between actual network output and desired output. If the training is successful the patterns are correctly classified. The network is trained until the error is minimum. The amino acid level is thus predicted in a particular protein sequence.

Q.1.    What is an experiment ?

    Answer
    
    An experiment is a means of getting an answer to the question that an experimentor (researcher) has in mind. This may be to decide which of the several pain relieving drugs that are available in the market, is the most effective or whether they are equqlly effective.
    
    An experiment may be planned to compare the yield of different varieties of wheat. so that the varity giving the maximum yield may be recommended to the farmers to increase their production.

1. Introduction

Milk is considered to be an adequate source of valuable macro nutrients, fat, protein, lactose. Vitamins and micronutrients making it a wholesome food. It can serve as an excellent carrier product for extra nutrient and if enriched or fortified it can satisfy the nutritional needs of the population. Soybean is an excellent source of low cost protein and has been an important nutritional component and medical investigation have revealed the great potential of soy foods for lowering blood cholesterol levels and the incidence of heart disease and cancer. The dry soybean contains roughly 40 % protein, 20% oil and 35% soluble (sucrose , raffinose, stachyose, etc. ). Aqueous extract of soya is an ideal substitute of animal milk for people suffering from allergic, gastrointestinal and other diseases peculiar to elderly people liu et al. (2004). Soymilk obtained by aqueous extraction from whole soybeans is a well known food product that is growing in popularity in many areas of the world (Hauman,1984). Soy milk is low in fat, carbohydrate, calcium, phosphorus, and riboflavin, but high in iron, thiamin, and niacin in comparison with cows’ milk. Soy milk contains higher amount of protein than buffalo milk and is deficient in sulfur containing amino acids. Soya milk is used in various products like paneer, yoghurts , cheese, tea and coffee whiteners , shrikhand, rasogolla and various indigenous milk sweets, confectionary, etc (Kale et al., 2012, Chang et al., 2005) also reported that intake of fermented soymilk improves the ecosystem intestinal tract by increasing the amount of probiotics. During the last years, soy beverages consumption has gradually increased due to their significant concentration of health promoting compounds, such as iso flavones.

Abstract

The per capita availability of fresh water in the World is continuously decreasing. It is reported that in the World about 69 percent of total water resources developed are used for irrigation, 23 percent for industries and the balance is used by the domestic sector. About 60 percent to 70 percent of water used in domestic sector is returned as waste water. Substantial quantities of water used by industries are also returned. To meet the increased food requirements of the global population, there is constant pressure for increase in food production. Since, agricultural productivity depends on availability of water; there is increased demand of water for irrigated agriculture. On the other hand, due to increased demand of water for other sectors, quantum available for irrigation sector is getting reduced. So, for meeting the increased irrigation demand, it is necessary to economise the use of water for irrigation by adopting improved technologies and improving the water use efficiencies.

Conservation Agriculture (CA) is an agro-ecological approach for sustainable crop production and intensification. CA comprises the resource conserving agricultural production practices that aim to achieve more produce at less cost while enhancing the quality of the natural resource base. CA is all about providing multiple options for farmers, endowed differentially. The basic components of CA include drastic reduction in tillage, adequate retention of crop residues on the soil surface, use of economically feasible diversified crop rotations, avoidance of freewheeling and practice of controlled traffic, if possible. These elements of CA are not site-specific but represent unvarying objectives that are practised to extend CA technologies efficiently across all production conditions. No-till agriculture is considered as a revolutionary step in the direction of preventing land degradation and rehabilitation of the resilient but fragile lands. No-till agriculture together with other associated management practices such as direct seeding into loose crop residues to provide soil cover and to conserve soil moisture, judicious choice of crop rotations and agro-forestry tree species constitutes CA. CA is thus being widely accepted as an important component of the overall strategy for enhancing productivity, improving environmental quality and preserving natural resources for food security and poverty alleviation in such areas.  Recent CA trials conducted in Karnataka, Andhra Pradesh and Tamil Nadu seem to bring out that the rainfed tropical India stands to benefit more from CA than the irrigated areas.

Abstract

Arsenic, although a non-metal, is very often referred to as a heavy metal. Its provenance and contents in recently formed or least weathered soils depend on the type of rocks and intensity of geochemical processes. The variation is exemplified in shale, where As content varies from 1 to 900 mg kg-1. In highly weathered soils, where pedochemical processes exceed geochemical processes, the content is generally below the levels that are toxic to life forms. In the Bengal basin, As content is low in soils, but high in the ground water (beneath the vadose zone). This suggests that As has been sufficiently leached from soils. The solubility of most of the As-bearing soil minerals is high, and it occurs as anions (AsO33-, or AsO43-) in soil solution. The soils of the Bengal basin are alkaline in reaction, mostly fine textured with almost even distribution of particle size fractions, and moderately drained. Minerals like micas and feldspars dominate their coarse fractions, whereas illite (40-47%) and smectite (24-30%) are dominant in clay fractions. Both inorganic and organic colloids are negatively charged that cannot retain anions. In many soils in the world, leaching of As is well documented. 

Abstract: Dry land ecosystems cover about 41% of the earth’s land surface including hyper arid region. There is a considerable difference between them, in which arid region covers 7% of global lands. These are barely productive and provide a meager existence to small populations, usually nomadic with little settlements as in Thar desert. In addition to hyper arid, other types are arid, semi and dry-subhumid, which are in danger of becoming desertified. Environmental conditions are harsh affecting agriculture production. People of Indian arid zone are well acquainted about agroforestry- an age old practice in India, but maintaining only a few trees on farmlands does not serve the growing demand of fodder, fueldwood and food. Adoption of alternate land use systems like alley cropping, lay farming, tree farming, dryland horticulture etc. may intensify crop production and sustain the rural livelihoods. The selection of tree/shrub species may be based on the tolerance towards drought, salitnity/alkalinity prevailing in the region. Based on arrangements and combinations of trees/shrubs with associated crops, agroforestry are categorized into: agri-silviculture, agri-horticulture, agripasture, silvipasture, hortipasture and silviherbal. Common trees are P. cinreraria, T. undulata, Salvadora oleoides, Acacia nilotica, A. tortilis, Ailanthus excelsa, Zizyphus nummularia, Z, mauritiana etc.

Introduction

In India importance of beekeeping is for honey production and little importance has till now been given to the primary biological and economic role played by bees in the pollination of agricultural crops. Honeybees are most fascinating creatures on the earth. They provide not only honey and also other valuable beehive products such as bees wax, pollen, royal jelly, propolis and bee venom. The bee forage in good quality is the primary requirement for production of the beehive products whereas efficient management and manipulation of bee colonies can competent for more production. A wise beekeeper adjusts to colony manipulation techniques according to floral and climatic conditions. In temperate regions there is enough flora during particular period i.e. spring and summer of the year and bees collect and store food but they face protracted dearth period in winter. Under subtropical climate of the country, nectar and pollen sources are available for most part of the year which are helpful for production of beehive products with quality.

16.1 Introduction

The broad bean is a hardy plant and can withstand sufficiently cold temperatures. It is cultivated on a small scale in India but widely cultivated in Latin America. This is the only bean which is sown in autumn and is grown as a winter crop (in temperate countries). Broad bean is used as green, shelled and dry beans and as a feed for livestock. Plants have distinguishing features like square and erect growing stems which grow up to 30 cm (dwarf cultivars) to 100 cm (tall cultivars). 

6.1 Introduction

It is an important vegetable in European countries. It got its name from the capital city of Belgium since it has been grown around Brussels for hundreds of years. From Belgium it has been introduced to England (1810). Some parts of Long Island in New York are also well known for Brussels Sprout production. In India, it is widely grown in Kodai kanal and Nilgiris hills of Tamil Nadu and Maharashtra. Exact statistics regarding area, production and productivity are not available. It is a cool, moisture loving and frost resistant biennial, with axillary buds produced in the leaf axils during the first year of growth and a seed head is produced in the second year of growth. Edible part is swollen axillary bud (sprouts or buttons or mini cabbage). 

12.1 Introduction

Carrot is valued as a nutritive food mainly because of high carotene content. The edible part of carrot is modified root (conical form, i.e., enlarged fleshy taproot). Although carrot is a biennial crop but it is grown as an annual for its root. Black carrots (Asiatic carrot root) are used for the preparation of a soft beverage called Kanji, which is supposed to be a good appetizer. Red type is good for preparing various types of sweets especially Gajar Halwa in northern India. Carrot seed oil is used for flavouring liquors and commercially used in France. The taste of carrot is due to the presence of glutamic acid. In carrot roots sucrose is the most abundant than glucose and fructose. Maximum concentration of carotene is found 85-100 days after planting. Carrot seeds contain germination inhibitor named as carrotal. 

3.1 Introduction

Cauliflower is a cruciferous vegetable that is naturally high in fibre and B-vitamins. It is said that the cauliflower has originated around the Mediterranean Sea. Ancestor of cauliflower is Brassica cretica which has been descended from the wild cliff cabbage, Brassica oleracea var. sylvestris, a native of coastal region of Europe and Africa. Cauliflower is cultivated worldwide in different climatic conditions ranging from temperate to tropics during most of the cropping seasons and is available round the year. Curd is the economic part of cauliflower and is an intermediate stage between vegetative and reproductive stage. It was introduced in India during the Mughal period. In 1822 a botanist Dr Jemson, In-charge of Company Bagh, Saharanpur, U.P introduced it in India from Kew Garden London. 

7.1 Introduction

Chinese cabbage appears to be native of China. It is known to have arisen from a cross between Pak choi (Brassica rapa var. chinensis, non-heading Chinese cabbage) from south China and turnip (Brassica rapa var. rapifera) from north China when they were grown together in the city of Young-chou. Artificial crosses between these species have proved this hypothesis. Its chromosome number 2n=20 distinguishes it from cole crops. It is not a member of cole group but regarded as very closely allied crop due to similarity in breeding systems, cultivation practices, season of growing and other features besides being like a member of Brassica vegetables. In general Pe-tsai cabbage, i.e., heading type (B. rapa subsp. pekinensis or B. pekinensis) and pak-choi cabbage, i.e., leafy type (B. rapa subsp.
