Improvement in post-rainy sorghum grain yield has been a challenge with M 35-1, a landrace selection released in 1937 dominating the post-rainy (rabi) tracts. It led to stagnation of post-rainy sorghum yields until the importance of specific adaptation was realized in lieu of highly variable soil and climatic conditions of post-rainy growing regions. As a result, Phule Maulee and of late Phule Chitra were released for regions of Maharashtra with medium soil depth.

Acid soils comprise up to 50% of the world's arable lands and in these areas aluminum (Al) toxicity impairs root growth, strongly limiting crop yield. Food security is thereby compromised in many developing countries located in tropical and subtropical regions worldwide.

The immediate and most common response by the different organs of a plant to water stress is decrease in turgor. This may be partially or fully adjusted by
accumulation of solutes. In the present study sorghum pollen grains were subjected to in vitro osmotic stress using polyethylene glycol (PEG). The change in size and shape of the pollen grains under osmotic stress

The people of Zimbabwe have to cope with a difficult political situation, but they also face many other problems daily. Climate change is making entire areas of land infertile and may halve crop yields by 2020. Zimbabwe

Local action can curb habitat loss and counter global pessimism on biodiversity. (Editorial)

Impacts of climate change vary from region to region. The 4th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) mentions that drier areas will be affected by more droughts while the rainfall regime, in general, will become

Farmers in mixed crop-livestock systems produce about half of the world
