PHOSPHORUS FERTILIZATION AND FOLIAR SPRAY WITH “GREENZIT” ON COWPEA YIELD AND QUALITY
2Agriculture Research Center, Ministry of Agriculture, Egypt.
Abstract
The present investigation was conducted at Shandaweel Agriculture Station, Sohag Governorate, Egypt, in the two successive Summer seasons of 1996 and 1997, to study the effect of four levels of phosphorus fertilizer i.e., 0, 30, 45 and 60 kg P2O5 / fed in the form of calcium super phosphate (15.5% P2O5) and number of foliar sprays with “Greenzit” fertilizer (1 cm / liter) i.e., once, twice and three times on yield and quality of cowpea cv. “Cream 7”. The obtained results indicated that : plant height, number of branches, early fresh yield, total fresh yield, dry seed yield, average weight of 100 seeds, shellout %, protein and phosphorus % in dry seeds were significantly increased when cowpea plants were fertilized with 60 kg P2O5 / fed. and sprayed 3 times with “Greenzit” fertilizer after 30, 45 and 60 days from sowing.
