Abstract

A field experiment was carried out at The Experimental Farm, Fac. Environ. Agric. Sci., Arish University, North Sinai, Egypt, during the summer seasons of  2014 and 2015.  The aim of this work was to study the effect of two organic fertilizer rates (100% and 200% of the recommended dose) with natural minerals (mixture of natural mineral ore) and natural rocks (phosphate rock  and feldspars) on growth, yield and mineral contents  of cowpea (Vigna unguiculata L.) cv. "Kafr-El Sheikh" under  sandy  soil conditions, using drip irrigation . A randomized complete block design, in three replicates was used. The results showed that applying cowpea plants with organic manure (ChM) and natural nutrient sources (mixture of natural mineral ore, phosphate rock and feldspars) had significant and positive effects on almost studied traits of growth and yield. The highest number of leaves/plant, plant height, leaf area, fresh weight and total yield  of cowpea plants were achieved when cowpea plants fertilized with double amount of organic manure with combination of natural nutrient sources.
