The projected demand of maize production in India in 2050 is 4–5 times of current production. With the scope for area expansion being limited, there is need for enhancement of yield. This calls for identifying areas where huge unrealized yield potential exists. With a view to address the issue, the present study delineates homogeneous agro-climatic zones for maize production system in India taking district as a unit and using the factors production, viz. climate, soil, season and irrigated area under the crop.

By 2050, India is likely to experience a temperature rise of 1-4°C; rainfall will increase by 9-16 per cent. This will have a detrimental effect on farmers in more than half of the country.

This paper attempts to analyse the determinants and impact of adoption of IPM practices in groundnut. This study is a part of a project "Assessment of Adoption and Impact of IPM in Rainfed Crops" funded by the Indian Council of Agricultural Research.
