Long-term use of fertilizers reduces crop yields. This decrease is due to the acidification of the soil, the reduction of biological activity of the soil and the inappropriate physical properties of the soil. So nutrient management plays an important role for obtaining economic and sustainable yields and increase crop productivity.
This study was carried out to evaluate combined effect of Sulfur and Sulfofertilizer1 of wheat cultivars on seed yield and its components.
Current research was done by using a split-plot experiment within randomized complete blocks (RCBD) design with three replications. The experimental treatments consisted of three levels of sulfur fertilizer (control, no consumption; 270g of sulfur fertilizer; and 270g of sulfur fertilizer + 6g of Sulfofertilizer1, biofertilizer) and three wheat cultivars (Mehregan, Chamran 2 and Khalil), which were assigned to the main and sub plots, respectively.
Result of analysis of variance revealed effect of different level of fertilizer (instead number of seed per spike at 5%), cultivar (instead number of seed per spike at 5%) and interaction effect of treatments on all studied characteristics (instead number of seed per spike and harvest index was not significant) was significant at 1% probability level. Assessment mean comparison result of different level of fertilizer indicated the maximum amount of grain yield (464.73 gr.m-2), number of spike per m-2 (416.5), number of seed per spike (40.1) , 1000-seed weight (43.11 gr), biologic yield (1400.8 gr.m-2) harvest index (33.17%) were noted for Sulfur + Sulfurfertilizer1 and lowest amount of mentioned traits belonged to control treatment. Compare different level of cultivar showed Khalil was superior to another one and had the highest amount of measured traits.
Generally result of studied research revealed using Sulfur + Sulfurfertilizer1 by Khalil cultivar had the highest amount of studied characteristics and it can be advice to farmers.
