Impact of Different Levels of Chicken Manure on the Growth and Yield of Common Bean (Phaseolus vulgaris-L.) under the Agro-Climatic Conditions of Kabul

Common bean (Phaseolus vulgaris-L.)  is one of the most popular pulse crops, providing substantial economic benefits in the farming communities of Afghanistan, and it is for both food security and income generation. it is an important source of calories, proteins, dietary fibers, minerals, and vitamins for millions of people in both developing and developed countries worldwide. Organic fertilizers play an important role in the growth, yield, and yield attributes of beans. To study this, an experiment was conducted at the Agriculture Faculty of Kabul University during, (2025) growing season, examining the effects of three different levels of chicken manure (control, 10 t/ha^-1, 15 t/ha^-1, and 20 t/ha^-1) on the yield and yield components of common beans (Phaseolus vulgaris -L.) under Kabul’s Agro-climatic conditions. Different crop agronomic traits, including to the growth and yield parameters such as plant height, number of branches per plant, number of leaves per plant, number of pods per plant, number of seeds per pod, biological weight t/ha^-1 100-seeds weight, and grain yield t/ ha^-1.  The experiment was conducted in a Randomized Complete Block Design (RCBD), and the data were analyzed with Statistical Tools for Agricultural Research (STAR 2.0.1) software. The results of research indicated that different levels of chicken manure had significant effects on all studied traits (plant height, number of branches/plant, leaves number/plants, number of pods/ plants, number of seeds /pods, one hundred seed weight and seed yield t/ha^-1), According to statistical analysis, 20 t/ha^-1 chicken manure improved growth and yield characters of common bean. For increased productivity of common beans in Kabul climate, the farmers are recommended to apply a proper dose of chicken manure.
