Study of Some Factors Affected on Dry Seed Yield and its Components of Common Bean (Phaseolus vulgaris L.)

Abstract

This experiment was suggested to study the beneficial effects of some levels of NPK fertilizers i.e. (0, 50, 75 and 100%) from NPK recommendation for common bean with humic acid (HA) on plant growth, dry seed yield and its components, quality and seeds chemical composition of common bean(Phaseolus vulgaris L.) cvs. Nebraska and Bronco. All experiments were achieved at the Experimental Farm of Kaha Research Farm, Horticulture Research Institute, Agriculture Research Center (ARC), Qaliobia Governorate, Egypt, during the two successive summer seasons of 2013 and 2014. The results showed that adding humic acid (HA) to common bean plantswith the level of 50% from NPK recommendation gave the highest values of vegetative growth, total dry seed yield and its chemical composition with cv. Nebraska or also cv. Bronco which cultivated under these study for the purpose of dry seed production. This treatment also led to save 50% of NPK fertilizers for common bean requirements. For that, it can be recommended that fertilization of common bean plants for the purpose of dry seed production by 50% from common bean NPK recommendation plus humic acid (HA) to obtain significant highest dry seed yield with best quality and at the same time save 50% from mineral fertilizer recommendation of common bean.
