Abstract

Two field experiments were conducted during 2005 and 2006 at El-Baramon Experimental Farm, El-Dakahllia Governorate, Hort. Research Institute. In order to study response of cowpea plants El-Balady  cv.  grown during late summer season to foliar feeding with some biostimulants (amino acids– seaweed extracts) and organic nutrients,(potassium borate citrate, organic boron,zinc citrate, calcium citrate, NPK-Humate)besides to NAA, on growth, mineral composition and yield and its components towards, maximizing its productivity under such season condition.
The results could be summarized as follows:
The applied treatments were significantly differed among them and were superior the control in all growth parameters, mineral concentration (NPK and Ca) in leaves, seed yield and its components during the two seasons.
The best ones in diminished order were KB-citrate NPK-humate, NAA, amino acids, B-EA (organic boron), seaweed extracts, Zn-citrate and at least Ca-citrate, those increased their plants, dry weight and total seed yield increased over the control by (35.67%,43.9%), (26.79% ,35.01%), (26.36% ,35.1%), (24.66% ,30.8%), (24.63% ,32.3%), (17.98% ,27.5%) ,(16.64%,25.8%)  and (5.73%,20.5%) means of the two seasons, respectively. Also, these treatments resulted in significant increase in concentration of N,P,K and Ca in leaves compared with the control one.
It could be sprayed late summer grown cowpea plants with potassium  borate citrate (3ml/L) or NPK-humate (2.5ml/L) to obtain the best growth and mineral concentration and the maximum total seed yield.
