Introduction

India is gifted with varied agro-climatic conditions for growing an array of vegetable crops to combat the present ill-balanced diet. The brinjal belongs to the family Solanaceous and to the genus Solanum, species melongena. The egg plant, Guinea squash are some synonyms to brinjal. It is a hardy crop and does best in worm and moist climate. The crop is generally grown twice or thrice in a year. The edible part, fruit is of high nutritive value and can well be compared with tomatoes. Insect pest constitute the major limiting factors in the successful production of brinjal. Pest comples of brinjal is very high and aphid (Aphis gossypii) causes heavy damage to the crop. Aphis gossypii (Hemiptera: Aphididae) is a tiny insect or greenfly in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae.

Introduction

The vast majority of climate change impacts and the overall impact of climate change on rice production are likely to be negative. Overwhelming scientific research and evidence have shown that the climate is ongoing. According to the International Food Policy Research Institute (IFPRI) report Climate Change: Impact on Agriculture and Costs of Adaptation forecasts there will be an increase in the net price of rice between 32 and 37% as a result of climate change by 2050. They also show that yield losses in rice could be between 10 and 15%. While there is still ongoing scientific exploration into climate change, IRRI recognizes two universal trends predicted by all climate change models viz., temperatures will increase, resulting in more heat stress and rising sea levels and there will be more frequent and severe climate extremes.

Abstract 

The on-farm programme on SRI was carried out in the village Narayanpur under RLI command area in Karimpur II Block of Nadia district in the year 2016 during summer season. The soil of farmland is clay loam and situated having latitude of 23°54’26.5"Nlongitude 88°30’24.1"Eat an average elevation of 9.75 m above the mean sea level. Monsoon ceases during October and cool season sets in by November. The average rainfall of this region is about 1500 mm and normal monsoon breaks in the first week of June. Though water resources in this area are generally satisfactory and 90% of these resources are tapped form the ground water source through deep and shallow tube wells. However, due to faulty crop planning and lack of scientific water management approach, a significant portion of agricultural area is identified as gray zone from hydrological point of view. Even many tube wells are becoming dry due to over exploitation of valuable water from the lower depths of confined aquifers. Rice is predominant crop during kharif season becoming less profitable because of high input costs involved. Summer rice gave satisfactory yield but also profitable proposition because of more input cost and less farm gate prices.  

Systematic Sampling (Meaning and Concept)

In this chapter, we are going to discuss the systematic random sampling technique. This is a random / probability / quantitative sampling method. In our previous chapter, we discussed the stratified random sampling technique. We have said that this technique is used when the population is heterogeneous and needs to be stratified into homogeneous groups. We have also discussed steps to be followed when using stratified random sampling as well as the strengths and limitations of stratified random sampling. Systematic sampling is a commonly employed technique if a complete and up-to-date list of the sampling units is available. The procedure involves choosing the very first object arbitrarily and the remaining members of the sample will be selected naturally according to any pre-decided sequence containing regular spacing of units. In this method, units of the population are numerically, geographically, and alphabetically arranged either in ascending or descending order (generally ascending order is preferred). When the ordering of the elements is related to the characteristic of interest,

Introduction
The major non-mulberry silkworms include the following

1.    Tasar silkworm Tasar silkworm is wild. Larva of tasar silkworm spins a ring like structure around the twig and a long peduncle before constructing the cocoon. Cocoons are large, thick and pedunculate. Cocoons are referred as ‘Hens’s eggs’. They are made of a single unbroken filament and hence are reelable. Tasar silkworm is bi/ tri/ tetra/ pentavoltine. This silk is brown colored silk. Monia or Mauni vessel, a palm leaved vessel is used to rear tasar silkworm in olden days.

a)    Indian Tropical Tasar, Antheraea mylitta (Saturniidae: Lepidoptera) This silkworm commonly found in tropical India. It is polyphagous and feeds on a number of food plants. Its principal host plants are asan (Terminalia tomentosa), arjun (T.arjuna) and Sal (Shorea robusta). Secondarily it feeds on Ber (Zizyphus sp.) The cocoons are grey white, tough and pedunculate.

Abstract

Being a great nutrient rich fruit, Dragon fruit has fetched a worldwide attention already and started to emerge as an important cash crop in global market. But the fine tuning between the scheduling of supply and market demand is greatly influenced by postharvest management and storage techniques of the fruit as the fruit has a short storage life. In this review, effect of diversified storage and packaging techniques on the different post harvest quality of fruits viz. fruit firmness, skin colour, its nutritional quality and susceptibility to disease pest during storage is investigated. And it was seen that various alternative and innovative modern techniques such as introduction of  plastic film, plastic crate packaging, modified atmospheric storage, different chemical application and application of edible chitosan coating are proven as effective to extent the durability of storage that widen the room for transport and marketing. Finally it can be said that the advantage of growth in dragon fruit consumption and marketing can be more harnessed through understanding the missing links between harvest and post-harvest handlings and integrating the traditional and modern postharvest approaches.

Introduction

Canning is the general term applied to the process of packaging a food in a container and subjecting it to a thermal process for the purpose of extending its useful life. An optimal thermal process will destroy pathogenic (disease-causing) Bacteria, kill or control spoilage organism present and have mineral impact on the nutritional and physical quality of the food. Although we thing of canning in term of steel or possible aluminium cans, the principle apply equally well to a variety of food containers such as glass jar, plastic and foil laminated pouches, semi rigid plastic tray or bowls, as well as metal cans of any one of several shapes, including cylindrical, oval, oblong or rectangular. The concept of aseptic packaging (sterilizing the food and the container prior to filling and sealing) also follows the same principles.

Introduction

There are both ants and white-ants present in this world since long. Although wrongly called, white ants or termites are responsible for substantial losses due to their infestation or attack not only to agriculturally important crops, but also to buildings and constructions, which in other way creates a hurdle to advancement of civilization. It will be an injustice if the beneficial role of them rendered to the society is remained unmentioned. Their ability to digest cellulose helps these insects recycle the entire base of the nutrient of this earth. But in terms of wastage and destruction, particularly in buildings and constructions, it surpasses the other damages mainly in the sectors like agriculture. In a latest literature, it was estimated that the world suffered an annual loss of 40 billion USD, owing to the attack of termites on various constructions (Liston, 2015).

Test for Significance of Population Proportion

A fundamental problem facing researchers today is how to make effective use of available wealth of online background domain knowledge to improve their understanding of complex biological system. Effective use of such online background domain knowledge plays a crucial role in all stages of integrated biological studies.

In the past years, research in molecular biology and molecular medicine has accumulated enormous amounts of data. This includes genomic sequences gathered by the Human Genome Project, gene expression data from micro array experiments, protein identification and quantification data from proteomics experiments, and SNP data from high-throughput SNP arrays. However, the understanding of the biological processes underlying these data lags behind. There is a strong interest in employing methods of knowledge discovery and data mining to generate models of biological systems. Mining biological databases put forward challenges which knowledge discovery and data mining have to address in the future. Important background knowledge in bioinformatics is often contained in documents, such as scientific publications or database annotations. Analyzing data from biological databases often requires the consideration of data from multiple relations rather than from one single table. Recently, approaches (such as propositionalization algorithms) are being studied that utilize multi-relational data and yet meet the efficiency requirements of large-scale data mining problems.

INTRODUCTION

The avocado (Persea americana Mill) is the highly nutritive fruit. Its common names are alligator pear or butter fruit in English; Aguacate, Palta in Spanish and Avokado in Afrikaans. It is an evergreen sub-tropical fruit. 

NUTRITIVE AND CULTURAL SIGNIFICANCE

Avocado is the most nutritive among fruits. The pulp is rich in proteins and fat, but low in carbohydrates. Avocados have the highest energy value of 245 cal/100 g and reservoir of several vitamins and minerals. Avocado is rich in copper and iron, potassium and is associated with lower blood pressure as it is high in monounsaturated fat. It contains all amino acids. Another benefit is avocados shown to maintain good cholesterol while reducing bad cholesterol and triglyceride level.. Avocado is considered healthy for heart ,good for digestion and vision. It is a natural detoxification fruit and may help in preventing osteoporosis
Avocado is mainly used fresh, in sandwich filling or in salads. It can also be used in ice creams and milk shakes and the pulp may be preserved by freezing. The fat in avocado is similar to olive oil in composition and is widely used in the preparation of cosmetics.

INTRODUCTION

The ber or Indian jujube (Ziziphus mauritiana Lamk.) in the most common fruit crop grown in arid and irrigated zones of Indian sub-continent. It is one of ancient fruits of India which is cultivated practically all over the country for its fresh consumption. Ber is a tropical as well as subtropical fruit and can be successfully cultivated even in the most marginal eco-system of tropics and subtropics. Ber is a hardy fruit tree and is best known for growing under adverse soil and climatic conditions. It can thrive well even in drought, water-logged and salinity conditions. It is common notion among the people that ber is a poor man’s fruit. It is one of the most nutritious fruit compared to other ones. The grafted varieties of ber fetch even higher price in the market than several other fruits. Hence, ber stands no longer the poor man’s fruit. Now, ber growing has received a great attention and preferred as a commercial fruit crop in North Indian states like Punjab, Haryana, Rajasthan and Uttar Pradesh on account of its potential for higher yield and good economic return to the growers. Moreover, the tree has less water need in the summer months during the period of dormancy, thus considered an ideal fruit for cultivation in the arid and semi-arid regions of North India. Apart from ber, no other fruit trees grow wild so extensively in this region, thus it is becoming popular among the growers.

INTRODUCTION

Mango (Mangifera indica L.) belonging to Family Anacardiaceae is the most important commercially grown evergreen tree of tropical and subtropical regions of the world. Due to its wide range of adaptability, high nutritive value, colorful fruits, richness in variety, delicious juicy taste and excellent flavor, it possesses high commercial value. It is sometimes also called ‘apple of the tropics’. It is believed that cultivation of mango originally started in South East Asia where it is being cultivated for last four to six thousand years. Now, it is cultivated in 112 countries of the world. India has the richest collection of mango cultivars.

Introduction

There is a growing interest in the role of different types of land use systems in stabilizing the atmospheric CO₂ concentration and reducing the CO₂ emissions or on increasing the carbon sink of forestry and agroforestry systems. Forestry has been recognized as a means to reduce CO₂ emissions as well as enhancing carbon sinks. There is considerable interest to increase the carbon storage capacity of terrestrial vegetation through land-use practices such as afforestation, reforestation, and natural regeneration of forests, silvicultural systems and agroforestry (Brown 1996; Canadell and Raupach 2008). Agroforestry systems are very important given the area currently under agriculture, the number of people who depend on land for their livelihoods, and the need for integrating food production with environmental services (Garrity 2004; Makundi and Sathaye 2004).

Abstract
This paper presents a lucid and application-oriented delineation of the theory of probability which has proved itself as a basic tool in the theoretical and applied researches in almost all disciplines of science, specially, in the problems encompassing the real-life issues. Bio-informatics has recently emerged as a potential discipline of science and, needless to mention that the application of the probability theory has delved deep to elucidate the laws under its ambit. The inference procedures based on biochemical systems require the formulation of stochastic models (owing to the prevalence of low to moderate levels of stochasticity and noise in their dynamics) which, in turn, are developed using the probability laws in abundance. In Systems Biology, the estimation of parameters poses a prime task in biokinetic models developed on experimental data, and such estimation procedures have been possible only by applying appropriate tools derived using probability. Likelihood-free Bayesian inference that explicitly accounts for discrepancies between the model and the data, termed Approximate Bayesian Computation under model uncertainty is an off-shoot of the celebrated, Bayes' theorem of probability.
