Abstract

Today, all countries of world try to get progress in productivity in other word; they try to get more output by decreasing input usage. In order to study the effects of application nitrogen level fertilizer on energy indices and economic indices of rice cultivars (Oryza sativa L.), an experiment as factorial in RCBD with three replications was conducted during 2009 year in the Rice Research Institute, Iran, Rasht, central of Guilan and Rudsar, East of Guilan. Also, for this purpose, a number of questionnaires were prepared and distributed among the rice producers of the examined region. Factors were cultivar (Khazar, Ali Kazemi and Hashemi), and nitrogen fertilizer levels (0, 30, 60, and 90 Kg N/ha). Results indicated that cultivar and nitrogen fertilizer significantly effected on energy indices and economic indices. Khazar have the highest production energy to consumption energy ratio among cultivars. With increasing N fertilizer application, production energy to consumption energy ratio increased significantly. Hashemi and Khazar have the highest benefit to cost ratio among cultivars. With increasing N fertilizer application, benefit to cost ratio increased significantly. Khazar have the highest productivity among cultivars. With increasing N fertilizer application, productivity increased significantly.
