Abstract

This study summarizes the findings of research organized in two parts. The first part includes the impact of climate and socio-economic factors that affected wheat yield in northwest India during the 2000s. The second part focused on the forecast of average wheat yield for the two highest wheat producing states Punjab and Haryana.

Initial study focused on the impact of climate factors on wheat yield in northwest India. It has been found that above normal temperature coupled with water shortage i.e. irregular irrigation and low soil moisture contributed to the prolonged yield reduction during 2002-2010.

Next, we reviewed the socio-economic factors which might be responsible for the wheat yield reduction along with climate factors. Lastly, an attempt has been made to forecast (2 years) wheat yield for the two states with very limited input. Despite of the limited input, the fitted model worked well and produced around 74% forecast accuracy. This short-term forecast can help crop management planning and other decision planning for the next few years.
