Performance of Green Bean (Phaseolus vulgaris L.) Varieties in Response to Poultry Manure in Sudan Savanna of Nigeria

Nutrients are limiting factors in green bean cultivation in the Sudan Savanna agro-ecological zone of Nigeria. Thus, field trials were conducted in the 2018 rainy season at the Teaching and Research Farm of Faculty of Agriculture, Bayero University, Kano and Teaching and Demonstration Farm of Department of Agricultural Education, Federal College of Education, Katsina. To study the growth and yield performance of green bean varieties as affected by poultry manure. The treatments consisted of two green bean varieties (Bean Cora and Haricot Contender) and three different rates of chicken manure (0, 2.5 and 5 t ha-1 ). The experimental design employed was l Randomized Complete Block Design (RCBD) with three replicates. Data collected were analysed (ANOVA) using the Genstat statistical package. The results revealed that varieties differed significantly in most of the studied characters. Haricot Contender recorded significantly higher canopy height, number of leaves per plant, plant dry matter and leaf area per plant than Bean Cora. While, Bean Cora significantly produced more pods per plant, pod weight per plant and green pod yield than Haricot Contender. The results also indicated that 5 t ha-1 of poultry manure application significantly increased all the studied characters compared with 2.5 t ha-1 and control. Based on this Study, Bean Cora is a promising variety in these locations. Further research using poultry manure to ascertain the optimum rate for higher green bean production in the Sudan Savanna of Nigeria is required.
