selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. the present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. for this purpose an experiment was c...

The use of software agent systems and technologies to simulate water resources management scenarios and improve the engagement of stakeholders in policy making is gaining paramount importance. Such importance originates from two main concerns or change agents. Firstly, the context of water management is becoming highly complicated due to the intensity of connections with other systems, the dive...

This paper identified the factors influencing the rice crop residue burning decision of the farmers and the potential of the burnt residue to generate electricity. For this study, data were collected from 400 farmers in the rice-wheat cropping system. Effects of different variables on the burning decision of rice residue are investigated through logit model. A number of factors had significant ...

In recent years, with climate change, drought stress has been witnessed in many parts of the world. In many irrigated regions also, shortage of water supply allows only limited irrigation. These conditions have an adverse effect on the productivity of many crops including cereals such as wheat. Therefore, genetics of drought/water stress tolerance in different crops has become a priority area o...

Background: Cotton with coevolving pests has been grown in India more than 5000 years. Hybrid cotton was introduced in the 1970s with increases in fertilizer and in insecticide use against pink bollworm that caused outbreaks of bollworm. Hybrid Bt cotton, introduced in 2002 to control bollworm and other lepidopteran pests, is grown on more than 90 % of the cotton area. Despite initial declines,...

High yielding irrigated hard red winter wheat (HRW, Triticum aestivum L.) is frequently low in protein and marketed at a discount. Protein is affected by available nitrogen (N) but few published reports relate to N fertilization practices for producing high yielding irrigated hard red winter wheat with acceptable protein in arid environments. A three year study (1985–1987) was conducted (1) to ...

Conservation agriculture in its version of permanent raised bed planting with crop residue retention has been proposed as an alternative wheat production system of western Uttar Pradesh.Therefore the present work was undertaken during 2008-2011 to compare permanent and tilled raised beds with different residue management under irrigated conditions. Permanent beds with residue retention resulted...

A model that integrates biophysical simulations in an economic model is used to analyze the impact of climate change on crop production. The biophysical model simulates future plantmanagement-climate relationships and the economic model simulates farmers’ adaptation actions to climate change using a nonlinear programming approach. Beyond the development of average yields, special attention is d...
