INFLUENCE OF ZINC UNDER DEFICIT IRRIGATION ON GROWTH AND PRODUCTIVITY OF HYBRID MAIZE


 Zinc (Zn) is an integral part of many enzymes and proteins required by plants for different physiological functions. The field study was conducted to determine the influence zinc on growth yield maize hybrid under skipping irrigations at stages. experiment comprised two factors, irrigation treatment viz regular system (8 irrigations, control) skip knee high tasseling stages Zn application treatments i.e. non-Zn as control, soil @ 9, 18 27 kg ha-1. laid out in randomized complete block design (RCBD) with split plot arrangement having three replications. results showed that ha-1 gave maximum leaf area index (5.16), crop rate (20.26 g m-2 day-1), 1000-grain weight (255.03 g), grain (5.64 t ha-1) harvest (34.5%) than lower doses minimum recorded control treatment. Similarly, improvement observed full while skipped stage negatively influenced height stage. In conclusion, applied normal helped improving autumn planted maize.
