Impacts of projected changes and variability in climatic data on major food crops yields in Rwanda

This paper investigated the response of major food crop yields namely beans,cassava, Irish potatoes, maize and sweet potatoes to ongoing changes in climate inRwanda. The projected daily precipitation and temperature data for the period2000-2050 used in this study were generated by stochastic weather generator(LARS-WG) from daily raw data for the period 1961 -2000. These data werecollected from ...

Impact of Climate Change on Yields of Major Food Crops in India: Implications for Food Security

The study has analysed changes in climate variables, viz. temperature and rainfall during the period 1969-2005 and has assessed their impact on yields of important food crops. A significant rise was observed in mean monthly temperature, but more so during the post-rainy season. The changes in rainfall, however, were not as significant. While an increase in maximum temperature was found to have ...

Agronomic Approaches for Increasing Iron Availability to Food Crops

Iron availability in calcareous soils, and Fe uptake and translocation in plants are major factors limiting the agricultural use of land. The nutritional value of crops as Fe sources for humans is often reduced due to Fe-deficiency in plants. Agronomic approaches to overcome these shortcomings include: (i) methods aimed at increasing the availability of indigenous soil-Fe; (ii) soil and/or foli...
