Abstract
A field experiment comparing the effects of cow dung, chicken droppings, and a mixture of both on the germination and growth parameters of maize (Zea mays) was conducted at the Botanical Garden, University of Maiduguri, located in the North-Eastern region of Nigeria. Treatments were arranged in a Randomized Complete Block Design (RCBD) with three replications. The variables assessed included the number of germinated seedlings, plant height, number of leaves, and plant diameter. Data collected were subjected to Analysis of Variance (ANOVA), and mean values were separated using the LSD test at a significance level of five percent. The results revealed that the application of organic manures, particularly chicken droppings (14.00), positively influenced maize germination and performance compared to N.P.K (2.00) treatments. Specifically, plots treated with chicken droppings exhibited the highest number of leaves (5.33), tallest plant height (49.17), and largest plant diameter (3.97) per plant. These findings suggest that chicken droppings have the potential to enhance the growth parameters of maize.
This study evaluated the effects of banana peel liquid organic fertilizer (LOF) and chicken manure on the growth and yield components of soybean (Glycine max L.) cultivated in Andisol soil. The experiment was conducted from December 2020 to April 2021 at the experimental field of the Faculty of Agriculture, Universitas Islam Sumatera Utara, using a factorial randomized block design with two factors: four doses of banana peel liquid organic fertilizer (0, 50, 100, and 150 mL polybag⁻¹) and four rates of chicken manure (0, 5, 10, and 15 t ha⁻¹). Data were analyzed using analysis of variance followed by Duncan's Multiple Range Test at the 5% significance level. The results showed that banana peel liquid organic fertilizer significantly increased the number of branches and the weight of 100 seeds but had no significant effect on plant height, stem diameter, or the number of pods. Chicken manure significantly increased stem diameter, number of branches, number of pods, and weight of 100 seeds, whereas its effect on plant height was not significant. No significant interaction was observed between banana peel liquid organic fertilizer and chicken manure for any of the observed variables. These findings indicate that both organic fertilizers independently improved soybean growth and yield components in Andisol soil, although their combined application did not produce a synergistic effect. Further studies involving comprehensive soil characterization, nutrient uptake, and economic evaluation are recommended to better understand the agronomic potential of banana peel liquid organic fertilizer under different environmental conditions.

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.

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.

Marginal soils are characterized by low nutrient availability, which adversely affects crop productivity. The incorporation of organic materials and cultivation techniques plays an important role in maintaining soil health and crop yield. This study aimed to evaluate the effects of photosynthetic bacterial fertilizers and the push-pull system cultivation technique. The research was conducted in Banjaran Village, Purbalingga Regency, utilizing a completely randomized block design. Treatments tested included S0 (control), S1 (50 mL/2L), and S2 (100 mL/2L), as well as P0 (control), P1 (lemongrass), and P2 (peanuts). Each treatment was replicated three times and analyzed using ANOVA, with Duncan's Multiple Range Test (DMRT) (α=5%) applied for significant differences. The observed variables included fresh plant weight, leaf area, fresh root weight, age of male flowers, and chlorophyll a levels. The results indicate that the application of photosynthetic bacteria significantly affects the fresh weight of the plants and the age of male flowers. However, there is no significant effect on leaf area, fresh root weight, and chlorophyll a levels. The push-pull system cultivation technique significantly affects chlorophyll a levels, although no significant differences were found in fresh plant weight, leaf area, fresh root weight, and age of male flowers.

Although nutrient management plays a crucial role in determining the productivity of barley (Hordeum vulgare L.), comparative information on the effectiveness of organic and inorganic nutrient sources under local conditions is still scarce. A field experiment was conducted during the 2024, Rabi season at Khairahani, Chitwan, to evaluate the effects of different nutrient sources on growth, yield, and profitability of barley var. Mustangey Jau. Using a randomized complete block design with five treatments-controls, chemical fertilizer NPK, poultry manure, farmyard manure, and vermicompost-each replicated four times, significant differences were observed in plant height, leaf area index, effective tillers, and grain yield. NPK fertilizer produced the highest plant height (94.80 cm), leaf area index (0.18), effective tillers (6.52), and grain yield (1.69 t/ha), followed by poultry manure and vermicompost. Organic sources improved growth over the control but yielded less than NPK. Economic analysis showed NPK achieved the highest net return and benefit-cost ratio (2.19), followed by poultry manure (1.34). Therefore, the application of recommended NPK fertilizer is suggested for maximizing barley yield and profitability, while poultry manure can be considered as a suitable organic alternative for improving productivity compared with other organic sources.

A field experiment was carried out during the wet season of 2026 at the Teaching and Research Farm of the Federal University of Technology, Akure. The aim is to examine the response of maize growth and biomass yield to inorganic (NPK) and complimentary organic fertilizer treatments. Initial soil samples were collected randomly from the experimental site and analyzed for some nutrients (N, P, K, Ca, Mg, Na, pH) and microbial (bacteria, fungi) population. The experiment was carried out using four treatments, organic, inorganic, organic plus inorganic and control with each treatment replicated three times. Each plot has a dimension of 3 m x 4 m. Agronomic parameters measured were plant height (cm), stem circumference (cm) and biomass yield (g). The results shows that at 10WAS), plot treated with organic plus inorganic fertilizer had the highest stem height (284.67cm); stem circumference (11.32 cm); and leaf dry weight (69.50g). The control treatment which had no fertilizer application recorded the least value of all agronomic parameters measured. The use of the combination of organic and inorganic fertilizer is therefore recommended for smallholder farmers for increased crop yield and soil fertility improvement under intensive continuous cultivation.
