Zinc-fertilization effects on wheat yield and yield components

Abstract: A field experiment was conducted in Department of Soil Science and Agricultural Chemistry, BAU, Ranchi during rabi season 2012- 13 and 2013-14. The objectives were to evaluate the effect of zinc (Zn) on the yield and yield contributing characters of wheat and to find out the optimum dose and method of Zn application for yield maximization. The treatments consisted of control (T0), 5 kg Zn ha-1(T1), 10 kg Zn ha-1 (T2) and 5 kg Zn ha-1 + 2 foliar sprays (T3). The basal dose of NPK at the rate of 120: 60: 40 kg ha-1 respectively, was applied to all treatments. The treatments were arranged in randomized complete block design with three replications. Results showed that effect of Zn application was significant on the grain yield (q/ha), straw yield (q/ha), and sterility percentage but had no effect on spike length, thousand grain weight and harvest Index. Average grain yield of two years is highest (3.93 t/ha) under the combination of soil and foliar application of Zn and lowest yield (3.36 t/ha) in control is observed. Maximum reduction in sterility percentage was found in soil along with foliar application of Zn. Based on the findings of study combined application of basal and foliar Zn on wheat may increase the grain yield.
