The response of two variety of Muskmelon to sprays different concentration of (Vit-Org) organic fertilizer

Abstract

This research was undertaken in the farm of the Horticulture department- college of Agriculture- University of Baghdad/ Abu-Ghraib (pH=7.5) and (Ec=4.2). During spring season of 2007, to investigate organic nutrient fertilizer on vegetative growth characters of sweet melon plant. Two variety experimented (Ananas an Hafed nafsa) with three levels of organic fertilizer (2, 3 and 4 ml/ l) were tested plus the control treatment.The Vit-org organic fertilizer contains ( organic N = 3% w/w , K2O =6% w/w , organic P = 13% w/w , total organic matter = 22.4% w/w), plants were sprayed for two times for two weeks intervals beginning with 30 days after transplanting to drip point with either distilled water. Factorial experiment in Randomize Complete Block Design was adapted with three replicates. The Ananas variety increased number of fruit/ plant, plant yield at 4.05 fruit/ plant and 7.78 kg/ plant respectively, spraying Vit- org at rate 4ml/ L increased fruit number and plant yield at 5.93 fruit/ plant and 8.54kg/ plant respectively, The Ananas variety increased plant length, number of branches/ plant, number of leaves/ plant, Dry matter/plant when vit-org sprayed at the rate 4 ml/ L, and increased fruit number/plant at 6.30 fruit/ plant and 5.57fruit/ plant for Ananas and Hafed nafsa variety respectively and yield/ plant at 11.43 kg/ plant for Ananas variety.
