Abstract

Effect of different levels of potassium sulphate and zinc sulphate on yield and yield components of CORN (hybrid SC 704) was studied in 2003 at Shushter, college of Agriculture, University of Azad. Four levels of potassium sulphate (0, 250, 500 and 750 Kg/ha) and three level of zinc sulphate (0, 50 and 100 Kg/ha) were evaluated using a factorial design with randomized complete block design in 4 replications. Evaluation of results showed that biological yield (By), grain yield (GY), 1000 grain weight, rate and duration of grain filling were increased significantly when 50 Kg/ha zinc sulphate were applied, but the effect of K SULPHATE was non-significant on these characters. Effects of ZN SULPHAte, K SULPHATE and interaction between both on By were (18.89, 17.97 and 17.92 t/ha) and on Gy were (8.59, 8.0 and 9.98 t/ha) respectively. Maximum Gy, number of seed per row, number of grain in cob and 1000-grain weight was obtained with 50 Kg/ha ZN SULPHAte (8589 Kg/ha, 42, 477 and 252 gr) and with 750 Kg/ha K SULPHATE (8003 Kg/ha, 43, 517 and 288 gr) respectively. Among yield components, 1000-grain weight had high regression with Gy. However, use of 50 kg/ha ZN SULPHAte increased grain yield up to 27.6% in compare to control treatments.
