Abstract
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.
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.

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.

A field experiment was conducted during the 2026 dry season at the Dryland Teaching and Research Farm of Usmanu Danfodiyo University, Sokoto, to evaluate the response of maize (Zea mays L.) variety Oba Super 11 to slow-release organo-mineral fertilizer (SROMF) formulations under the Sudan Savannah agro-ecological zone of Nigeria. The study was laid out in a Randomized Complete Block Design (RCBD) with five fertilizer treatments: (i) mineral fertilizer (NPK 20:10:10), (ii) NPK SROM fertilizer (20:10:10), (iii) NPK SROM fertilizer (15:10:10), (iv) NPK SROM fertilizer (12:6:6), and (v) a control (no fertilizer), replicated three times. Data were collected on growth and yield parameters. Results showed that fertilizer treatments significantly (p ≤ 0.05) influenced all growth and yield parameters measured. At 9 weeks after sowing (WAS), the tallest plants (181.5 cm) were recorded under NPK organo-mineral fertilizer (12:6:6), while the shorter plants (83.1 cm) were recorded in the control plot. Grain yield was highest in NPK SROM fertilizer (20:10:10), producing 6.6 t ha⁻¹, followed by the mineral fertilizer treatment (5.5 t ha⁻¹), while the control had the lowest yield (1.1 t ha⁻¹). Similarly, the highest dry matter yield (6.6 t ha⁻¹) was obtained from the NPK SROM fertilizer (20:10:10) treatment. The study concludes that slow-release organo-mineral fertilizers significantly enhanced efficient nutrient utilization and in turn improved growth and yield performance of maize under Sudan Savannah conditions, with the NPK SROM fertilizer (20:10:10) formulation showing superior grain yield performance and is therefore recommended as a sustainable nutrient management strategy for improving maize productivity while potentially reducing nutrient losses under different soil textural classes.

Declining soil fertility is a major constraint to sustainable crop production in sub-Saharan Africa, and sole reliance on inorganic fertilizers raises concerns about long-term soil health. This study evaluated the effects of maize cob biochar and NPK fertilizer, applied individually and in combination, on soil properties, growth, and yield of maize (
Zea mays
L.) in Akure, Nigeria. The experiment was conducted using a randomized complete block design with three replicates. Treatments included control, biochar (1.5 and 3.0 t/ha), NPK fertilizer (100 and 200 kg/ha), and a combined application of 1.5 t/ha biochar with 100 kg/ha fertilizer. Growth parameters measured included plant height, leaf area index, internode length, and stem girth, while yield indices and post-harvest soil chemical properties were also assessed. Results showed that all treatments significantly improved maize performance compared to the control. Biochar alone produced the highest growth values and yield components, including cob weight (375.12 g), number of seeds per cob (707.80), and seed weight per cob (203.53 g), compared to the control (161.50 g, 104.73, and 37.49 g, respectively). The combined treatment also recorded high values (313.52 g, 670.50, and 169.94 g). Biochar improved soil properties, increasing organic carbon (0.89%) and organic matter (1.52%) relative to the control (0.69% and 0.19%), while fertilizer enhanced available phosphorus (5.39 cmol/kg). The study concludes that integrating maize cob biochar with inorganic fertilizer is an effective and sustainable strategy for improving soil fertility and maize productivity.

The purpose of this study was to evaluate the growth and yield performance of three rice varieties under combinations of organic and mineral fertilisers in Burkina Faso and to identify a suitable organo-mineral formulation. A two-factor split-plot experiment with three replications was conducted using Nerica4, FKR84, and FKR60N. Two fertiliser dosages were assessed together with an absolute control. Dosage D1 comprised 9.4 kg of neutral soil, 600 g of organic manure, 4.5 g of NPK, and 3 g of urea, whereas D2 comprised 9.4 kg of neutral soil, 300 g of organic manure, 9 g of NPK, and 6 g of urea. The evaluated traits were production cycle, plant height, number and length of panicles, 1000-grain weight, theoretical paddy yield, and dry biomass. Fertiliser treatments significantly affected several growth- and yield-related traits, with responses varying among varieties and fertiliser combinations. Dosage D1 was associated with favourable production-cycle responses, particularly for the F6NU, F7NU, and F9NU combinations. Organo-mineral treatments also improved plant height and panicle traits, while the F2, F4, and F8 manures and their mineral-fertiliser combinations generally performed well for yield-related responses. Across the two dosages, D2 produced the more favourable paddy-yield response. These findings indicate that rice varietal performance depends on both fertiliser composition and dosage under the experimental conditions, with combined organic and mineral fertilisation showing potential for improving rice productivity. The results can be applied to guide the selection of promising organo-mineral fertiliser combinations and dosages for rice production in Burkina Faso, while field validation is needed before wider recommendation under farmers' conditions.

A field experiment was conducted during the spring season of 2024–25 at the Agricultural Research Farm, Lovely Professional University, Punjab, to evaluate the optimisation of sugarcane straw biochar rate and nutrient management on spring maize (Zea mays L.). The trial was laid out in a split-plot design (SPD) with 3 replications. The main plot received three different treatment levels of sugarcane biochar rate which included 5 t ha-1 (M1) and 10 t ha-1 (M2) and 15 t ha-1 (M3). Similarly, 4 treatments were selected for the subplot section, consisting of S1 for absolute control, S2 for 100 % recommended dose of nitrogen and phosphorus (RDNP), S3 for 50 % RDNP with nano di-ammonium phosphate (nano DAP) and S4 for 50 % RDNP with liquid nutrient foliar sprays. Results revealed that, M3 achieved the significantly highest plant height of 221.46 cm during harvest while also reaching the highest dry matter accumulation (DMA) of 230.06 g plant-1 and soil plant analysis development (SPAD) index of 45.53 which resulted in a 31.8 % grain yield increase compared to M1. The evaluation of different nutrient conditions showed that S2 and S3 performed equally well for all measured characteristics when compared to S1. Under the S2 treatment, both plant height and grain yield increased by 28.1 %, while yield attributes also showed improvement. The interaction showed distinct patterns because M3S2 achieved significantly highest growth and yield of spring maize. The maximum chlorophyll index (46.80), grain yield (57.03 q ha-1) and straw yield (75.03 q ha-1) were found in M3S2 which are statistically at par with M3S3 and M3S4. The combination of reduced fertiliser application with foliar treatment produced better crop results when biochar usage reached its peak level. Therefore, integrating sugarcane biochar with optimised nutrient level offers a pragmatic pathway for improving growth and productivity of spring maize in Punjab.
