Abstract
Production inputs are one of the most important factors affecting the risk of agricultural products. This study aimed at investigating the effects of inputs on the production risk of irrigated and rainfed wheat through the information collected from 221 producers of these products in eastern region of Golestan province of Iran in the 2015-2016 cropping year using the suggested model of Just and Pope (1979). The results showed that for both products, seed input had a significant positive impact on the average production; also, the inputs of fertilizer and consumed water had the production increasing impact on the average irrigated wheat production, while such an impact could be found by application of the inputs including fertilizer, pesticide, machinery and labor for the rainfed wheat. In addition, the study results indicated that the pesticide input used for both products had a risk increasing impact on the production; furthermore, the inputs of seed and labor for the rainfed wheat and the fertilizer and machinery inputs for the irrigated wheat reduced the production risk. Therefore, the study recommended using properly the risk reducing inputs at the right time to reduce the production risk of irrigated and rainfed wheat crops and as a result, to increase the average production of such a strategic product.
