ABSTRACT
The experiment was conducted to study the effect of seed enhancement treatments and growth regulators on plant growth and seed yield of maize hybrid Hema(NAH-1137)at ZARS, V.C.Farm Mandya during kharif 2013. The different seed enhancement treatment includes T1: No treatment (control), T2: Hydration and dehydration T3: Seed treatment with Vermi wash (75%) T4: Seed treatment with Spent wash (20%) T5; Seed fortification with Zinc sulphate (2%) T6; Seed fortification with Silicilic acid (4%) and growth regulators includes G1: No spray (control) G2: Triacontanol (10ppm) G3: Mepiquat chloride (200ppm) G4; Silicilic acid (4ml/lt). The result revealed that seed enhancement treatment ZnSo4 (2 %) recorded highest plant height (154.97 cm), number of leaves (15.50) at 90 DAS and chlorophyll content of leaves (22.53) at harvest, cob length (17.53 cm), cob weight (184.10 g), seed yield (2680 kg ha-1), followed by seed treatment with spent wash (20 %). Among the different growth regulators tried, highest plant height (156.49 cm) and number of leaves (15.32) at 90 DAS was observed with 10ppm Triacontanol. Spraying thecrop with 200ppm Mepiquat chloride at 30 and 45 DAS recorded highest chlorophyll content of leaves (22.58) at harvest, cob length (17.33 cm), cob weight (183.79 g), seed yield (2689 kg ha-1) which was on par with Triacontanol at 10ppm. Hence it can be concluded that by treating the seed with 2 per cent Zinc sulphate and spraying of Mephiquate chloride is better plant growth and seed yield can be obtained.
