Abstract :

To evaluate effects of nano fertilizer and different levels of nitrogen on sesame, a factorial experiment, arranged in randomized complete block design with 3 replications, was done in the research station of Kahnoj. Factors in this experiment included four nano fertilizer (0, 1, 2 and 3 /1000) and N levels in four levels (0, 50, 100 and150 Kg N/hac). Analysis of variance showed significant effects of N and nano fertilizer on all characters. Maximum plant height, amount of capsul and biological yield was obtained in 150 Kg nitrogen and minimum level of these parameters was in 0 Kg N. In nano fertilizer yield per plant, amount of capsul and biological yield, was maximum in (3/1000) treatment, while plant height was maximum in 2/1000 treatment. N fertilizer together with nano fertilizer increased 1000 kernel weight, grain yield and biological index, in comparison with none fertilizer treatment and the highest amount of this parameters was in 100 kg N and 2/1000 nano fertilizer treatments. For the oil percent maximum average was 58.5% more than none N fertilizer treatment and maximum amount of oil between nano fertilizer was obtained in 2/1000 and the minimum was in none nano fertilizer usage. Generally, it can be said that the effects of nitrogen and nano fertilizer increased availability of nutrients, which is required by plant, and caused the best growing condition for the sesame
