Zaheer Ahmed Arain
Abstract
The studies were planned to find out the effects of nitrogen and zinc alone or in combination on the biology of wheat TD-1, at Sindh Agriculture University Tandojam. The natural parameters contemplated are plant tallness cm, number of tillers m-2, spike length cm, number of grain spike-1, grain weight in gram plant-1, seed record or index (1000 seed weight g) and grain yield kg ha-1. The factual screening demonstrated that nitrogen and zinc spray at different dosages influenced essentially at (P≤0.05). The greatest plant tallness 65 cm, number of tillers m-2 298.3, spike length 9.2cm, number of grains spike - 1 56.5, grain weight plant-1 24.7 g, seed list 53.3 g, and grain yield 5907.3 kg ha-1 were recorded with 2 % nitrogen + 1 % zinc shower at tillering stage taken after by 2 % nitrogen + 1 % zinc splash at booting stage with 63-2 cm plant tallness. 283.3 number of tillers m-2, 8.7 cm spike length, 54.2 number of grains spike - 1, 22 g grain weight plant-1, 51.5 g seed list, and 5758 grain yield kg ha-1, while least plant tallness 51.3 cm, number of tillers m-2 256.7, spike length 7.0 cm, number of grains spike-1 38, grain weight plant-1 10.1 g, seed file 38 g, and grain yield 4111.7 kg ha-1 were recorded in the untreated control. It is concluded foliar nitrogen at 2 % + 0.1% Zinc remarkably increased the yield of wheat when applied at tillering stage.
