The present paper attempted to determine the trends in the food crop productivity in Jammu and Kashmir at agro-climatic zone level from 1980 to 2011. For the delineation of State into agroclimatic zones, altitude, precipitation-temperature regime, major crops are grown and agricultural productivity have been taken into consideration. The different map layers were prepared using suitable data base and methodologies. The superimposition of these map layers, viz., altitude zonation map, cropping land use map, productivity map and PT Index map resulted in the delineation of fourteen zones (five-climatic zones and nine agro-climatic zones). The productivity of the crops vary with the geo-climatic conditions and as a result of this, the productivity of rice (paddy) is highest in two zones of Jammu division (1J and 3J) and one zone of Kashmir valley (1K), while as productivity of maize is higher in zones of Jammu division (1J, 2J and 2'J) than Kashmir and similarly zone 2K is leading in the wheat productivity in Kashmir division and zone 3'J and 2'J are high productive wheat zones in Jammu division. The Ladakh division (zone L) is producing only wheat with the productivity of 17.26 q/ha (quintals/hectare). The productivity of all the three dominant crops doubled during these thirty years. On an average out of nine zones, the productivity in one zone is very high followed by three zones having high productivity; while as two zones each have medium and low productivity and one zone have very low productivity.
