Comparative Effects of Two Organic Fertilizers, Inorganic Fertilizer, and Their Integrated Application on Growth and Yield of Common Bean (Phaseolus vulgaris L.) at Kabul Condition

The sustainable management of soil fertility is essential for improving common bean (Phaseolus vulgaris L.) productivity under the semi-arid conditions of Afghanistan. This study evaluated the comparative effects of two organic fertilizers, inorganic fertilizer (NPK), and their integrated application on the growth and yield performance of common bean during the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University. The experiment was arranged in a Randomized Complete Block Design (RCBD) with six fertilizer treatments and three replications. Growth traits, yield components, grain yield, biological yield, and harvest index were analyzed using analysis of variance (ANOVA), and treatment means were separated by Tukey’s HSD test at the 5% probability level. Fertilizer treatments significantly influenced most growth and yield parameters. The integrated application of 50% OF-1 + 50% NPK (T5) consistently produced superior plant growth, increased yield components, and achieved the highest grain yield, biological yield, and harvest index compared with the sole application of organic or inorganic fertilizers and the unfertilized control. The improved performance of the integrated treatment was attributed to enhanced nutrient availability and more efficient nutrient utilization throughout the crop growth period. These findings demonstrate that integrated nutrient management is a sustainable and effective strategy for increasing common bean productivity under semi-arid agroecological conditions. Future studies should evaluate long-term effects of integrated nutrient management under diverse agroecological conditions.

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.
