This study was conducted from May–September 2025 / the 2025 growing season at the Research Farm of the Department of Agronomy, Faculty of Agriculture, Kabul University, to evaluate the effects of organic and inorganic fertilizers on the growth, yield, and yield components of mung bean (Vigna radiata L.) variety 08 Zudrus. The experiment was arranged in a randomized complete block design (RCBD) with four treatments with three replications. Treatments included a control, NPK fertilizer, XiR Biomass containing 10% humic acid, and XiR Biomass containing 20% humic acid. Data on growth, yield components, and yield parameters were analyzed using STAR software (version 2.0.1) through analysis of variance (ANOVA) at the 5% significance level. Fertilizer treatments significantly influenced several growth and yield traits. XiR Biomass containing 20% humic acid produced the tallest plants (35.10 cm), the highest number of pods per plant (10.53), and the greatest biological yield (7851.63 kg ha⁻¹), whereas XiR Biomass containing 10% humic acid produced the highest grain yield (2202.38 kg ha⁻¹) and number of grains per pod (11.00). In contrast, tiller number, branch number, pod length, pod width, and 100-seed weight were not significantly affected. Overall, XiR Biomass organic fertilizers showed greater potential than NPK fertilizer for improving mung bean growth and productivity under the agro-ecological conditions of Kabul.

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.
