Background: Food security has been a target in India since its independence; the primary aim of food security is to ensure enough staple food for the entire population. Although substantial progress was made through the adoption of green revolution (GR) technologies and implementation of the food public distribution system (PDS), desirable food and nutrition security, as defined by the food and...

We evaluated the ability of the WGEN model to generate long term weather series in situations where the actual historic weather data record is only 3–10 years long. The series generated were used to simulate yield of irrigated and rainfed chickpea. To do this, four 100-year samples of weather data were generated for Tabriz, Iran. The WGEN parameters used to generate data were obtained from dail...

Aim of study: To assess the impacts climate change on local agriculture with a high resolution in Mediterranean region diversity climates.Area Catalonia (NW Spain).Material and methods: Based historical meteorological records regionalization RCP4.5 model created by Catalan Meteorological Service, Papadakis agro-climate classification was calculated for two scenarios. The changes agro-climatic s...

In recent decades, there have been substantial increases in crop production in sub-Saharan Africa (SSA) as a result of higher yields, increased cropping intensity, expansion of irrigated cropping systems, and rainfed cropland expansion. Yet, to date much of the research focus of the impact of climate change on crop production in the coming decades has been on crop yield responses. In this study...

Genetic engineering provides a means to introduce genes into plants via mechanisms that are different in some respects from classical breeding. A number of commercialized, genetically engineered (GE) varieties, most notably canola, cotton, maize and soybean, were created using this technology, and at present the traits introduced are herbicide and/or pest tolerance. In 2007 these GE crops were ...

The inconsistency of the Indian monsoon has constantly threatened country’s food production, especially key crops such as rice. Crop planning measures based on rainfall patterns during rice-growing season can significantly improve sustainable water usage for water-intensive This study examines variability monsoonal in rainfed and irrigated rice-cultivating regions to utilization irrigation wate...

(eds M.C.S. Wopereis et al.) 35 Upland environments are situated at the high end of the toposequence, where rice depends solely on rainfall as the water table is out of the reach of rice roots for much of the growing season. At the lower end of the toposequence, rice plants can reach the water table or profit directly from flood water. Along the toposequence, interactions exist between environm...

In August 1990, a 2-ha plantation was established in an area where rainfall (about 515 mm year(-1)) was insufficient to meet evaporative demand. On nine occasions between September 1991 and April 1993, pressure-volume curves were constructed for irrigated and rainfed Eucalyptus globulus ssp. globulus Labill. and E. nitens (Deane and Maiden) Maiden trees. During the experiment, rainfed trees exp...
