Abstract
Two field trials were carried out in the farm of Research and Production Station, National Research Centre, Nubaria District, AL-Behaira Governorate, Egypt, during the two successive summer seasons of 2010 and 2011 to study the effect of nitrogen fertilizer and Zn foliar application at different growth stages on yield, yield attributes and some chemical traits of groundnut. Results showed that increasing N levels from 30 to 40 kg N/faddan significantly increased number of pods/plant, weight of pods/plant, weight of seeds/ plant, 100-seed weight, pod yield/faddan, seed yield/faddan and straw yield/faddan. Use of Zn foliar application either at flowering or seed filling stages significantly increased number of pods/plant, weight of pods/plant, number of seed/ plant, weight of seeds/plant, 100-pod weight, 100-seed weight, pod, seed and straw yield/faddan, oil yield, seed protein content, N and K content in the seed and straw compared to control treatment. The studied characters of yield and yield attributes were significantly affected by the interaction between nitrogen fertilizer levels and foliar Zn application. Groundnut treatment with 40 kg N/faddan + Zn foliar application at seed filling stage recorded the highest significant values of most studied characters than the other treatments followed by the same nitrogen level and Zn foliar application at flowering stage. The data of nitrogen use efficiency calculated (kg seeds/kg N) revealed that there were synergistic effect of the combined application of nitrogen and zinc either at flowering or seed filling stages. Such synergistic effect was more pronounced when the lower level of N( 30 kg N/faddan) was applied .The maximum efficient use of N for producing seeds was attained at seed filling stage (37.1 and 31.45 kg seeds /kg N) when zinc was combined with 30 and 40 kg N/faddan, respectively
