Abstract
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.
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.

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.

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.

Chickpea (Cicer arietinum L.) is an important pulse crop valued for its nutritional quality and role in sustainable agriculture. However, productivity is often constrained by low soil fertility and poor nutrient management, particularly phosphorus deficiency. A field experiment was conducted during the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University, Afghanistan, to evaluate the effect of different levels of diammonium phosphate (DAP) fertilizer on growth and yield of chickpea variety Flip 94. The experiment was arranged in a Randomized Complete Block Design (RCBD) with five DAP levels (0, 50, 100, 150, and 200 kg ha⁻¹) and three replications. Results showed that DAP application significantly influenced all growth and yield parameters, while replication effects were non-significant. Treatment 3 (100 kg ha⁻¹ DAP) consistently performed best, recording the highest plant height (34.23 cm), number of branches per plant (4.92), number of pods per plant (37.47), grains per pod (1.93), and grain yield (5.52 t ha⁻¹). In contrast, the control treatment recorded the lowest values for all studied traits. The improved performance under optimal DAP application is attributed to enhanced nutrient availability, better root development, increased nodulation, and improved photosynthetic efficiency, which collectively supported stronger vegetative growth and reproductive development. In conclusion, application of DAP fertilizer significantly improves chickpea growth and yield under Kabul agro-climatic conditions. Treatment 3 (100 kg ha⁻¹ DAP) was identified as the most effective dose for maximizing productivity of chickpea variety Flip 94.

Flax is among the most significant industrial oilseed crops in the world, as well as in Afghanistan. It is high in health-promoting fatty acids. However, its yield and quality are low owing to poor nitrogen fertilizer use and lack of improved cultivars in Afghanistan. Hence, a field trial was conducted at the Research Farm of the Agriculture Faculty of Kabul University during the main cropping season of 2025 to evaluate four nitrogen rates (0, 50, 100, and 150 kg/ha). The study was conducted using a randomized complete block design (RCBD) arrangement with four replications. The size of each experimental unit was 2 m × 2 m (4 m2), with six rows. Distances of 30 cm and 40 cm were left between plots and blocks, respectively. The spacing between rows was 30 cm, and the spacing between plants was 15 cm. Significant differences were observed in the different levels of nitrogen on plant height, number of capsules per plant, number of branches per plant, number of seeds per capsule, 1000-seed weight, length of roots, biological yield, grain yield, and straw yield. However, the results showed that the 100 kg N/ha fertilization level significantly outperformed in number of seeds per capsule, number of capsules per plant, 1000-seed weight, and seed yield. Meanwhile, the 150 kg N/ ha fertilization level excelled in plant height and number of branches per plant, biological yield, and straw yield.

A field experiment was conducted during the kharif seasons of 2024 and 2025 at the Experimental Farm, Department of Agronomy, School of Agricultural Sciences, Hapur, Uttar Pradesh, to evaluate the effects of different nitrogen and silicon levels on the yield attributes and yield of rice (Oryza sativa L.). The experiment was laid out in a Randomised Block Design with three replications and comprised nine treatment combinations involving the recommended dose of fertilisers (RDF) and varying levels of silicon applied through broadcasting and foliar application. The results showed that silicon application significantly influenced the yield attributes and yield of rice. Among the treatments, RDF combined with 120 kg Si ha⁻¹ through broadcasting (T₅) recorded the highest number of panicles (286.78 m⁻²), panicle length (26.08 cm), grains per panicle (83.06), and test weight (26.18 g). The same treatment also produced the maximum grain yield (5365.44 kg ha⁻¹), straw yield (7759.62 kg ha⁻¹), and harvest index (42.76%), which were significantly superior to the other treatments. The improvement in yield and yield attributes may be attributed to enhanced nutrient uptake, increased photosynthetic efficiency, better grain filling, and improved assimilate translocation under silicon application. The study indicated that the combined application of RDF and 120 kg Si ha⁻¹ through broadcasting is an effective nutrient management strategy for maximising rice productivity under the agro-climatic conditions of western Uttar Pradesh.
