Influence of spraying different nutrients in the growth and yield Hybrid of peppers Capsicum annuum under greenhouse

Abstract

The experiment was conducted in Agricultural season 2014-2015 beneath heated plastic house condition which belong to Agricultural state nursery / Kirkuk government, to study the effect of organic nutrition spraying on growth and yield of three pepper hybrid Capsicum annum L. the nutrient following were used Humque acid G , seaweed extract P and alga cifo 3000 V in addition to control treatment Three hybrids were used Mandera H1, Remus CR×6122 H2 and Festose H3 . The experiment designed as split plot design with two factors, and hybrid distributed in main plots , while the nutrient distributed in secondary plot with three replicates for two factors , so the experiment included 36 experimental unit. The results were analyzed using in SAS of composed in using Duncan that multiple boards at level 0.05 . The result were summarized as following :H2 had highest chlorophyll contacts , H1 recorded significant increasing in fruit diameter and weight, while H3 in fruit length , there are no significant differences between the hybrids to individual plant yield. The nutrient spraying with G spraying recorded spurting in main leave content of chlorophyll , leaves area and fruit weight , For the interaction between nutrient and hybrids the interaction between of H2 with G had superiority in total chlorophyll contact . H1 with P in total leave area. Nutrient effect appeared significant in all quantitve and qualitative characters expect number of fruit character It superior as a comparison treatment. the interaction between H1 and G significant increasing in fruit diameter, fruit, length and weight fruit while interaction between H2 and G in characters yield, total yield and individual plant yield, the interaction between G, H3 had superiaty in fruit length .
