Abstract :

In order to study the effects of organic and nanobiologic fertilizers with three intervals of irrigation on seed yield of sesame (Sesamum indicum) a field experiment was conducted in Touredan region of Khonj in 2012. The experimental design was split plot based on Randomized Complete Blocks Design with three replications. Treatments included: fertilizer treatments with 8 levels (control, manure, compost, manure + compost,  nanobiologic, nanobilogic + manure, nanobiologic + compost and  nanobiologic + manure + compost) as first factor and irrigation intervals with 3 levels (8, 12 and 16 days) as second factor. Results indicated that irrigation intervals had no significant effects on studied traits such as seed yield, 1000- seed weight,  height of main stem and number of capsules. But irrigation intervals influenced shoot dry weight and leaf area significantly. Also fertilizer treatments had significant effects on traits in this experiment. Interaction between fertilizer treatments and irrigation intervals was significant in 0.05 probability level. Also interaction between treatments and different irrigation intervals was significant at 0.05 probability level. In general the effects of fertilizer treatments and irrigation intervals fertilizer treatment (Nano + Compost) with irrigation interval (16 days) was suggested as the best treatment in condition of the experiment.
