Description Anantapur is the driest district of Andhra Pradesh and hence, agriculture conditions are very often precarious. Groundnut grows where
other crops fail and thus it is the predominant crop of Anantapur district. Groundnut is grown in about 7.5 lakh ha in Anantapur districtÍž
however the average yields are low af 500 kg ha1.
Among various available vegetation indices, normalised difference vegetation index
(ND VI) is widely used for all reasons, which is a single numerical indicator of presence and condition of green vegetation. ND VI
mapping at a regional scale helps to assess the spatial changes in the vigour of green vegetation and thus occurrence of any moisture
stress. Climate tOQls have a great role in understanding the crop performance and estimating the yields. This study was taken up by
using freely available MODIS data to understand ND VI in terms of abiotic stresses over Anantapur district and linking with the actual
rainfall conditions, groundnut crop acreage and production. Results indicate that low groundnut yields in general,could be related to ND
VIbased
stress measurements and rainfall quantum and distribution in the area however, with a few exceptions. It is hoped that by
combining improved practices through IWM with climateadapted
crop varieties, rainfed farmers of Anantapur district can sustain their
crop production under present climate variability and become resilient to future climate change
