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 district; however the average yields are low
af 500 kg ha-1. 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 VI-based 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 climate-adapted crop
varieties, rainfed farmers of Anantapur district can sustain their crop production
under present climate variability and become resilient to future climate change
