Effects of zinc , boron and sulphur on the yield and nutrient uptake of wheat crop

A field trial was carried out to investigate the effects of Zn, B and S when applied alone or in combination on the yield and nutrient uptake of wheat at New Developmental Farm the University of Agricultural Peshawar during winter season 2010. The experiment was carried out in Randomized Complete Block Design replicated three times having row to row distance of 25 cm and plot size of 3x5 m. The NPK fertilizers were applied at rate of 120:90:60 kg hain the farm of urea, DAP and potassium chloride, respectively. Sulphur, zinc and boron were applied at rate of 60:10:2 kg ha in form of ammonium sulfate, hepta-hydrated zinc sulfate and borax, respectively. All the treatments revealed significant (P<0.05) differences for all the traits. The treatment receiving zinc, boron and sulphur was significantly higher which showed maximum dry matter yield and grain yield. Significantly higher1000-grain weight was found in treatment of Zn with S Uptake of leaves P, B, SO4-S and Zn was found significantly higher in the treatment of S + B + Zn. The overall result suggested that when sulphur, zinc and boron applied at the rate of 60:10:2 kg hacollectively produced maximum yield.
