EFFECT of FOLIAR SPRAY of ASCORBIC ACID and CHELATED IRON on GROWTH and YIELD of Cucurbita pepo L.

Abstract

An experiment was conducted during autumn season of 2010 at Al-Harta, Basrah. The aim was to study the effect of foliar spraying of ascorbic acid and chelated iron on some vegetative growth, flowering and yield of Cucurbita pepo cv. Kanna F1. The experiment included 5 treatments came from (0 , ascorbic acid concentration of 40 , 80 mg/l and chelated iron 6% concentration 300 , 600 mg/l Randomized Complete Block Design was used in a simple experiment. Results showed that were a significant effects for foliar spraying of ascorbic acid at 40 mg/l and chelated iron of 600 mg/l on vegetative growth, flowering and yield and its components foliar Spraying with 40 mg/l ascorbic acid and 600 mg/l chelated iron gave the highest yield per plant (1.1840 and 2.084)kg respectively and the highest total yield per unitarea (7.233 and 8.187) ton/dounm. For both parameters, respectively.
