Abstract
This research was carried out under the temperate climate condition of Ilam province, Iran, during 20122014 growing seasons to determine the suitable crop rotation for enhancing nitrogen agronomic efficiency of wheat.The experiment was performed in a split plot arrangement based on randomized complete block design with 4 replications. The main plots consisted of 6 Green manure plant treatments (Control, Perko PVH, Buko, Berssem Clover, Oilseed radish and combination of three plants Ramtil, Phasilia, Clover), and sub-plots were allocated to four levels of nitrogen fertilizer (Zero, fertilizer recommendation, 50% lower and 50% higher than the recommended fertilizer).The results showed that there were significant differences among the green manure treatments for the grain yield. The highest and lowest grain yield, with 7020, and 4969 kgha -1 were obtained for Perko green manure and Control, respectively. The highest and lowest nitrogen uptake efficiency was obtained for Oilseed radish green manure and Fallow rotation, respectively. The difference between the various green manure was significant for nitrogen use efficiency. The green manure of Oilseed radish increased nitrogen economic performance up to 30.65 kg kg-1. The Nitrogen Uptake Efficiency in Oilseed radish green manure was the highest with 0.86 kg per kg of nitrogen. Finally among the cultivated varieties, Perko and Oilseed radish was superior compared to the other four cultivars.
