The Effect of Inorganic Nitrogen and Phosphorus Fertilizers, Chicken Manure and Their Combinations on Growth and Development of Common Bean (Phaseolus vulgaris L.)

Common bean is one of the most widely grown of grain legumes, being cultivated from the tropics to temperate regions. The present study was aimed to determine the effect of chicken manure doses, nitrogen and phosphorus fertilizers on growth of common bean. The experiment was conducted from March to July 2020 in the Dicle University, Agriculture Faculty, Field Crops Department Experiment Farm. The treatments composed of control, 40N+80P kg ha-1, Chicken (C) 2000 kg ha-1, Chicken (C) 2000+40N+80P kg ha-1, Chicken (C) 3000 kg ha-1 and Chicken (C) 3000+40N+80P kg ha-1. Treatment was arranged in a randomized complete block design with three replications. The effect of chicken manure and nitrogen and phosphorus combinations on the plant traits is higher than the treatments alone. The differences among treatments for compared crop growth rates (CGR), net assimilation rate (NAR), leaf area index (LAI), leaf area duration (LAD) and specific leaf area (SLA) were significant, and the highest CGR, NAR, LAI values were in Chicken 3000+40N+80P kg ha-1. NAR of Chicken 3000 kg ha-1 and Chicken 3000+40N+80P kg ha-1 treatments were significantly lesser than those of the other treatments included control
