Genome editing is a technique in which changes are made in the DNA of any organism. A nuclease promotes breaks in the DNA at a specific sequence which is repaired by several mechanisms. It is one of the efficient technologies which enable us to change and edit genome of any organism precisely and accurately. Multiple genome editing technologies have been employed, including zinc finger nucleases, mega nucleases, clustered regularly interspaced short palindromic repeats (CRISPR) along with Cas9 protein and transcription activator-like effector nucleases to modify genome of an organism.

Mechanization in Indo-Gangetic plains of India is increasing progressively for the past decades. Use of energy intensive inputs is increasing in a modern intensive agricultural production system. The effect of energy intensive inputs are directly associated with the cost of crop production and environmental issues. These necessities the need of energy input – output analysis. This paper presents the energy input-output analysis of rice (Oryza sativa L.) – wheat (Triticum aestivum L.) cropping system studied at Indian Institute of farming system research, Modipuram from 2011 to 2014.

Professional fisheries education is a new branch of science, which is having tremendous potential sooner rather than later. A new era in the professional fisheries education in India started at the State Agricultural/Veterinary Universities with the establishment of first Fisheries College at Mangalore in 1969. Presently, there are thirty professional fisheries colleges in India. Professional fisheries graduates have employment opportunities in fisheries departments of Central and State Governments, fisheries research institutes, academic/ universities and so on.

Fruit Crops yield and quality significantly increase with the use of micronutrients such as zinc (Zn), iron (Fe), Calcium (Ca) Magnesium (Mg) Boron (B), Copper (Cu), Manganese (Mn), etc. Zinc (Zn) has an important metabolically role in plants vegetative and reproductive phases; growth and development; is therefore called an essential trace element or a micronutrient.

This paper revealed striking difference in food consumption pattern of households across income groups and rural and urban sectors in Uttar Pradesh. Analysis of food consumption, using consumption expenditure survey conducted by NSSO, revealed a structural shift towards high value agricultural commodities like milk, fruits, vegetables and non-vegetarian products in the state. High disparity among income groups and ruralurban disparities in Monthly per capita expenditure were observed.

There are several innovations in floricultural industry such as value addition in flowers, vertical garden, drying of flowers, hydroponics, aeroponics, bonsai, flower arrangement these add beauty in nature. Value addition in flowers not only help the producer to get a good price for its produces but also helps the consumer as they get a good quality as well quantity added products. Hydroponics is a technology for growing plants in nutrient solutions with or without the use of an artificial medium to provide mechanical support.

Soil organic carbon (SOC) content is key component of the global carbon (C) cycle which is highly variable with respect to space and time. The main objective of this study was to provide an assessment of soil organic carbon (SOC) stock variability for Uttarakhand state. The other objective of this study was to evaluate the performance of different pedotransfer functions for reliable assessment of bulk density. Soil Resource Mapping for Uttarakhand state was conducted on 1:50,000 scale with the help of Satellite imagery (LISS III) along with exhaustive ground truthing through soil surveys.

Access to safe drinking water and sanitation is a basic necessity. However, such access is highly variable around the world and in particular in Africa, Asia and South America. Much progress still remains to be made in infrastructure improvements and poverty reduction. A recent World Bank report, for example, noted that more than 100 million people in the Latin American region alone lack access to potable water and adequate sanitation systems. Compounding the issue of water availability is contamination of water supplies and the lack of wastewater treatment facilities.

Soil erosion is a hazard traditionally associated with agriculture in tropical and semi-arid areas and is important for its long-term effects on soil productivity and sustainable agriculture. It is, however, a problem of wider significance occurring additionally on land devoted to forestry, transport and recreation. Erosion also leads to environmental damage through sedimentation, pollution and increased flooding. The costs associated with the movement and deposition of sediment in the landscape frequently outweigh those arising from the long-term loss of soil in eroding fields.

The acre-yields of crops on dry-farms, even under the most favorable methods of culture, are likely to be much smaller than in humid sections with fertile soils. The necessity for frequent fallowing or resting periods over a large portion of the dry-farm territory further decreases the average annual yield.

It is widely accepted that irrigation allows for the increase and stability in agrarian yields, being a necessary tool to support food supplies and necessities for certain raw materials in the world. However, irrigated agriculture is also considered the most significant fresh water consumer and one of the main causes of pollution, degradation and depletion of natural resources. These impacts are primarily related to changes in the water cycle, salinization of agricultural soils, and salinization and pollution of water resources due to the use of agrochemicals....
