Effect of Foliar Application of Chemicals and Plant Growth Regulator on Growth and Yield of Baby Corn (Zea Mays L.)

Abstract

The present investigation was conducted in the Orchard, Department of Horticulture, Faculty of Agriculture, Annamalai University, Chidambaram, Cuddalore District, Tamil Nadu to find out the “Effect of foliar application of chemicals and plant growth regulator on growth and yield of Baby corn (Zea mays L.)”. The experiment was conducted in a Randomized Block Design with ten treatments in three replications. The foliar applications of chemicals and plant growth regulators viz., Naphthalene Acetic Acid (NAA) at 10, 20 and 30 ppm was applied @ 25 and 35 DAS, Nano urea at 1, 2 and 3 ml were applied first at 25 DAS and second at 20 days after the first spray, Potassium nitrate (KNO3) @ 1 per cent was applied at 1 week before silking. Among the various treatment combination, the application of 100% RDF + 30 ppm NAA + 3 ml Nano urea + 1% KNO3 was found to have the percentage increase in the growth and yield of Baby corn and could be used commercially, for large scale production.
