Buckwheat is gaining attention as a promising crop because of its nutritional value and ability to grow under diverse environmental conditions. This study investigated the performance of three buckwheat varieties Common Buckwheat, Devyadka, and Zyloni under the agro-climatic conditions of Kabul during the 2025 growing season. The field experiment was carried out at the Research Farm of the Faculty of Agriculture, Kabul University, using a randomized complete block design with four replications across two contrasting field environments. Several growth characteristics, including plant height, leaf number, leaf width, and number of branches per plant, together with total biomass and 100-seed weight, were evaluated. The results revealed that plant height, leaf number, leaf width, and total biomass varied significantly among the varieties and between environments, with a clear interaction between genotype and environmental conditions. These findings indicate that the growth and productivity of buckwheat are strongly influenced by the environment in which each variety is cultivated. In contrast, the number of branches per plant and 100-seed weight remained relatively stable across environments, suggesting that these traits are less affected by environmental variation. Among the tested varieties, Devyadka produced the greatest vegetative growth and biomass under favourable conditions but showed greater sensitivity to environmental changes. Common Buckwheat maintained consistent performance across both environments, demonstrating strong adaptability and stable productivity, while Zyloni displayed moderate performance with reasonable stability. The study concludes that environmental conditions play an important role in determining buckwheat performance in Kabul. Considering both yield potential and stability, Common Buckwheat is the most suitable variety for cultivation under the variable agro-climatic conditions of the region.

This study evaluated the effects of different rates of diammonium phosphate fertilizer on the growth, yield, and yield components of common bean under field conditions at the Faculty of Agriculture Research Farm, Kabul University, during the 2025 growing season. The experiment was conducted using a randomized complete block design with three replications and four fertilizer treatments: 0 (control), 30, 60, and 90 kg ha⁻¹ of diammonium phosphate. Data were collected on vegetative growth traits, including plant height, number of branches, and number of leaves, as well as reproductive traits such as number of pods per plant, grains per pod, pod length, pod width, 100-seed weight, and grain yield. The data were analyzed using analysis of variance, and treatment means were separated using the least significant difference test at the 5% significance level. Fertilizer application significantly affected most growth and yield parameters. The application of 60 kg ha⁻¹ produced the greatest vegetative growth, recording the highest plant height (33.8 cm) and number of branches (4.47), while the unfertilized control produced the highest number of leaves (36.4). The application of 90 kg ha⁻¹ resulted in the highest reproductive performance, including number of pods per plant (12.33), grains per pod (4.00), pod size, 100-seed weight (66 g), and grain yield (1090 kg ha⁻¹). The findings indicate that moderate fertilizer application promotes vegetative growth, whereas a higher application rate maximizes reproductive development and grain yield. Therefore, applying 90 kg ha⁻¹ of diammonium phosphate is recommended to improve common bean productivity under agroecological conditions similar to those of the study area.

Phosphorus deficiency is one of the main factors restricting mung bean (Vigna radiata L.) production in many parts of the world, including Afghanistan. Therefore, a field experiment was carried out in the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University, to determine the influence of different diammonium phosphate (DAP) fertilizer levels on mung bean growth and yield. The experiment was arranged in a randomized complete block design (RCBD) with three replications, consisting of four DAP rates: 0, 30, 60, and 90 kg ha⁻¹. The collected growth and yield data were analyzed using analysis of variance (ANOVA), and mean comparisons were performed using the Least Significant Difference (LSD) test at a 5% probability level. The application of DAP fertilizer significantly improved plant height, shoot dry matter, number of branches, pods per plant, pod length, seeds per pod, and 100-seed weight. However, leaf number, grain weight per square meter, seed yield, and harvest index did not show significant differences among fertilizer treatments, although higher values were generally observed compared with the control treatment. The maximum seed yield (870.83 kg ha⁻¹) was obtained from the application of 60 kg DAP ha⁻¹, while the highest performance for most growth and yield-related traits was recorded under 90 kg DAP ha⁻¹. The findings suggest that DAP fertilizer application enhances mung bean growth and yield performance under the environmental conditions of Kabul. Among the tested fertilizer levels, 60 kg DAP ha⁻¹ was found to be the most effective rate for achieving higher grain yield.

Soybean is an important legume crop valued for its high protein and oil content, but its productivity is often limited by poor soil fertility and environmental stresses. This study aimed to determine the optimum potassium application rate for improving soybean growth and yield under the agroecological conditions of Kabul, Afghanistan. A field experiment was conducted during the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University, using a randomized complete block design with five potassium levels (0, 25, 50, 75, and 100 kg ha⁻¹) and three replications. Standard agronomic practices were applied uniformly throughout the experiment. Data were collected on plant height, branches per plant, pods per plant, total seeds per plant, 100-seed weight, and grain yield, and analysed using STAR software with the least significant difference test at the 5% probability level. Potassium application had no significant effect on vegetative growth traits, including plant height and number of branches per plant. However, it significantly improved yield components and grain yield. The application of 75 kg K ha⁻¹ produced the highest number of pods per plant, greatest 100-seed weight, and maximum grain yield, whereas increasing the rate to 100 kg K ha⁻¹ resulted in reduced yield. The findings indicate that potassium application enhances soybean productivity primarily through improved yield components rather than vegetative growth. It is concluded that 75 kg K ha⁻¹ is the optimum potassium rate for maximizing soybean yield under the agroecological conditions of Kabul, Afghanistan.
