Abstract

Field experiment was carried out on private orchard at El – Khamella , Abyan Governorate, during two consecutive growing seasons 2013-2014, to study the effect of different doses of nitrogen , phosphorus and potassium on growth and yield of papaya cv. Honey dew . Nitrogen fertilizer was applied with three levels 50, 100, 150 gm N\plant, phosphorus with three levels: 50, 150, 250 gm P2O5\plant, and potassium with three levels: 100, 200, 300 gm K2O\plant. Randomized complete block design with 10 treatments and three replicates were used. Results indicated that best yield was with 150, 250, 300 gm\plant N, P ,K different levels of fertilization has affected other characteristics: an increase in plant height, stem diameter and fruit weight; an increase in fruit number per plant with 100, 250, 200 gm\plant N,P,K and pulp thickness with 150 , 250 , 300 gm\ plant N,P K. Juice of fruits contains a high total soluble solid with 100, 250 , 300 gm\ plant N,P K, and acidity was affected with different levels of fertilization.
