اثر کاربرد منابع مختلف تغذیهای زیستی و شیمیایی بر اجزای عملکرد و عملکرد کنجد

Today, over-reliance on chemical inputs for agricultural production caused serious environmental and economical concerns. In order to study the effects of biological and chemical sources of nitrogen, phosphorus and sulfur on yield components and yield of sesame, an experiment was conducted based on randomized complete block design with three replications and ten treatments including Nitroxin (Ni), Biophosphor (BP), Biosulfur (BS), biological double mixture of Ni+BP, biological triple mixture of Ni+BP+BS, Urea (U), triple super phosphate (P), chemical double mixture of U+P, chemical triple mixture of U+P+elemental sulfur and control. Treatments had significant effect on the number of capsules per plant, biomass in hactare and grain yield, but had not affected the number of grain per plant, 1000-grain weight and harvest index. Maximum yield was achieved in biological and chemical mixture treatments. There was no significant different between mixture treatments. Considering the benefits of biofertilizers and need to replace them with chemical inputs, biological double or triple mixture treatments is suggested to sustainable production of sesame.
