Malaysia’s heavy reliance on imported soy-based feed ingredients poses significant
challenges to both food security and sustainability in its livestock sector. As an
underutilised legume with high protein content and strong ecological adaptability,
Canavalia ensiformis (L.) DC. (jackbean) offers a promising local alternative. This study
investigated the combined effects of different growing media (clay, cocopeat, sandy soil,
and topsoil) and organic amendments (control, composted chicken manure, green manure,
and biochar) on the growth performance and yield of jackbean. The experiment was
conducted using a randomised complete block design (RCBD) with five replications, and
plants were harvested after 12 weeks. The data on plant height, number of leaves, number
of branches, pod length, pod number, flower production, chlorophyll content, shoot
biomass, and root biomass were analysed using two-way ANOVA in RStudio. The results
demonstrated that sandy soil amended with green manure (GM) consistently produced the
highest values for plant height (185.61 cm), number of leaves (84.90), number of branches
(33.63) and pod length (17.00 cm). GM in topsoil had higher chlorophyll content (33.08),
while it had the highest shoot dry weight (56.18 g) and root dry weight (6.48 g) in
cocopeat. GM showed the most robust and consistent enhancement across all media types,
indicating its superior nutrient supply and positive effects on rhizosphere microbial
activity. In contrast, biochar amended performed poorly, particularly when applied in
sandy and topsoil, likely due to poor drainage and nutrient immobilisation. These findings
revealed the importance of selecting optimal combinations of organic inputs and soil
media to maximise jackbean productivity and highlight their potential as a sustainable
crop for protein-rich feed production, supporting the efforts to reduce Malaysia's
dependency on soybean imports and enhance agroecological resilience. This study aligns
with the Sustainable Development Goals (SDGs), particularly SDG 2 (Zero Hunger) and
SDG 12 (Responsible Consumption and Production) by promoting sustainable crop
management and enhancing food security.
Papaya (Carica papaya L.) is a fast-growing, nutrient-demanding fruit crop with continuous vegetative and reproductive development. The present study evaluated the effects of organic manures and bio-inoculants, applied with different levels of inorganic fertilisers, on the growth, flowering, yield attributes, and fruit yield of papaya cv. CO 7 under the humid tropical conditions of Kerala. The field experiment was conducted in a randomised block design comprising 12 treatments, three replications, and four plants per treatment. Treatments included combinations of the recommended dose of fertilisers (RDF; 240:240:480 g NPK plant⁻¹ year⁻¹), farmyard manure, vermicompost, poultry manure, biovermi, bone meal, wood ash, Trichoderma viride, and Pseudomonas fluorescens. Biometric, floral, and fruit characteristics were recorded, and the data were analysed using MSTAT.C, with treatment means compared by DMRT. The treatment comprising RDF + vermicompost (13 kg plant⁻¹) + T. viride (5 g plant⁻¹) + P. fluorescens (10 g plant⁻¹) recorded the greatest plant height, collar girth, fruit length, fruit girth, fruit weight, fruit volume, seed number, and fruit yield. This treatment produced 42.59 kg fruit plant⁻¹. RDF + poultry manure (10 kg plant⁻¹) + the two bio-inoculants recorded the highest number of fruits per plant and a yield of 40.93 kg plant⁻¹. Fully organic treatments yielded less than the integrated nutrient treatments. Under the conditions of this study, combining RDF with vermicompost and bio-inoculants was the most effective nutrient-management treatment for papaya cv. CO 7.

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.

Canola (Brassica napus L.) is one of the key oilseed crops worldwide, serving as a vital source of edible oil, livestock feed, and biofuel. In Afghanistan, canola production faces significant challenges due to declining soil fertility and over-reliance on expensive chemical fertilizers. Poultry manure, as a low cost and nutrient-rich organic fertilizer, offers a sustainable alternative for improving crop productivity. However, limited scientific information is available regarding the optimal poultry manure application rate for canola under Kabul’s agro-climatic conditions. Therefore, an experimental research was conducted at Kabul University Agricultural Research Farm during the 2025 cropping season using Randomized Complete Block Design (RCBD) with three replications and four treatments. The study aimed to evaluate Effects of Different Levels of Poultry manure on Growth, Yield, and Yield Components of Canola. The findings of the study revealed that the application of poultry manure significantly influenced on growth, yield and yield components of canola. Overall, the application of 8-ton poultry manure ha-1 had better performance than control. The maximum plant height (117.45 cm), number of branches plant-1 (5.65), number of leaves plant-1 (39.77), number of siliques plant-1 (184.61), silique length (6.01 cm), number of seeds silique-1 (18.39), thousand seed weight (3.40 g), seed yield (2.74 t ha⁻¹), biological yield (9.87 t ha⁻¹), and harvest index (27.76%) were all recorded in T4. The lowest values for all parameters were observed in the control treatment (T1). It is recommended that use 8 tons of poultry manure ha-1 in order to realize optimal seed yield and biological yield of the crop.

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.

A significant issue in the wheat production systems is the need to increase the efficiency of nutrient use without compromising soil health. This paper has examined the synergistic impact of organic manures, Nano-DAP on growth, yield and soil fertility of wheat (Triticum aestivum L.) under field conditions during the Rabi seasons of 2023-24 and 2024-25 in Lucknow, India. The treatments were: green manure, farmyard manure and vermicomposting (5 t ha-1), with various nutrient management strategies based on Nano-DAP. The findings indicated that vermicompost was highly beneficial in promoting crop growth, with the highest values in terms of plant height, density and biomass growth. Nano-DAP seed treatment and foliar sprays, combined with 100% NPK, created the greatest grain yield (49.64 q ha-1) and better yield characteristics than traditional fertilization. It was also seen that the combined application enhanced the uptake of nutrients and the soil fertility status.In general, the results imply that the combination of organic Manures and NanoDAP is an efficient and sustainable approach to nutrient management to achieve better wheat yields and better soil health.

The heavy use of chemical fertilisers for a long period of time deteriorates the soil quality and productivity of the crop. So, a field trial on “Effects of poultry manure and seaweed extract on growth and yield attributes of rice (Oryza sativa L.)” was conducted during the kharif season (2024) at the Agri Farm, Lovely Professional University, Punjab to evaluate the effectiveness of poultry manure and seaweed extract on the growth and yield of rice. The field trial was structured in a split plot design with three replications; the main plots were poultry manure with four levels (0, 5, 10 and 15 t ha-1) and the subplots were seaweed extract with four levels (0 %, 0.25 %, 0.75 % and 1 %), forming 16 treatment combinations and 48 plots. Results demonstrated that increasing levels of poultry manure significantly improved plant height, number of tillers, dry weight, panicle length and grain yield. The highest grain yield (6.33 t ha-1) and harvest index (48.21 %) were noted with 15 t ha-1 poultry manure (M₄). Among the seaweed extract treatments, 1 % foliar spray (S₄) produced the maximum grain yield (6.01 t ha-1) and harvest index (48.22 %). The combined application of 15 t ha-1 poultry manure + 1 % seaweed extract (M₄S₄) produced the maximum grain yield (7.19 t ha-1). Thus, integrating poultry manure and seaweed extract proved to be a sustainable and eco-friendly practice for improving rice productivity.
