Abstract

 In order to study the effect of some physiological traits and yield of basil (Ocimum basilicum L.) under different planting dates and POTASSIUM FERTILIZER amounts, an experiment was carried out as factorial based on completely randomized blocks design with three replications.Potash fertilizer was in 4 levels (40, 60, 80 and100 Kg per hectare) and SOWING DATE included 2 levels (25th April and 20th May). The traits included, leaf dry weight, stem dry weight, leaf dry weight and BIOLOGICAL YIELD per unit area at 2 harvesting was evaluated. Based on the results, the impact of applying POTASSIUM FERTILIZER on yield, leaf dry weight, stem dry weight, leaf dry weight per unit area of BIOLOGICAL YIELD at 1% probability level in the first and second harvest were significant. Also, single effect of SOWING DATE on leaf dry weight, stem dry weight, leaf dry weight per unit area and BIOLOGICAL YIELD were significant at 1% probability level. The mean comparison results demonstrated that 60, 80 and100 Kg /ha Potash fertilizer increased the yield 6%, 16% and 28% compaired with 40 Kg /ha in first harvesting time and 7%, 9% and 19% at second  harvesting time alternatively.
