In a pilot study conducted in South India, farmers who followed the cropping advisory derived from climate and crop simulation modeling earned 20% more than those who did not heed the advice.A majority of the farming community in Hussainapuram, Kurnool, Andhra Pradesh, India, live below the poverty line. Over 50% of the cultivators hold less than two hectares of dryland. Twice in every five years the village experiences drought. Recurrent droughts force migration to nearby cities for employment. In this region the deep black soils are deficient in major and micro nutrients like nitrogen, phosphorus, sulfur, boron and zinc. Cotton, groundnut, sunflower and chickpea are the major crops in the region. Cotton growers have been the worst hit by changing rainfall patterns.
