Original Article
Integrated application of wood ash and inorganic fertilizer sources on vegetative growth, fruit yield, and nutrient quality of Solanum aethiopicum L.

Purpose: Wood ash is an important alternative source of inorganic potassium especially for farmers in areas with acidic soils. Method: The experiment was carried out in two phases. In the first phase, treatments consisted of the application of inorganic fertilizer sources (0 kgha-1, 130.44 kgha-1 of urea, and 300 kgha-1 of NPK of 20:10:10) and […]

The effect of vermicompost leachate and split root system of tomato on the growth and crop per drop

Purpose: This study aimed to investigate the effects of vermicompost leachate on the growth and water use of tomatoes in an unequal distribution of salinity in a hydroponic system.Method: Roots of tomato seedlings were separated into approximately two equal parts, each half was grown in a media culture part containing a 3-liter perlite and cocopeat […]

Effects of biochar on the chemical properties of soils and the volume of wood in a plantation of Acacia mangium Willd in the Colombian Orinoquía (highlands)

Purpose: Exploring alternatives to mitigate soil degradation has been gaining importance in recent years. Biochar promises to improve properties such as soil fertility and soil conditioning. This research involved an experiment with different levels of biochar in associating it with some chemical properties and the wood yield of A. mangium. Method: We used a design […]

Original Article
A review of vegetable waste bio-processing techniques in rural areas

Purpose: Vegetable waste (VW) could cause environmental problems if not properly managed. Due to rural living conditions and a relatively low residence density, VW is usually disposed of in landfills. Waste management should be engineered in a way to process the waste into value-added products in a sustainable manner. This review evaluates four bioprocessing techniques […]

Original Article
Efficacy of biocompost from pineapple waste coupled with indigenous fungi strains Trichoderma spp. on soil fertility, nutrients uptake, growth, and yield of Ananas comosus (L.) Merr

Purpose: The current study aimed to figure out the types and dosages of biocomposts supplied with cellulose-degrading Trichoderma strains for ameliorating soil properties, and the growth and yield of pineapple. Method: The experiment with two factors followed a completely randomized block design, including 20 treatments (4 replications). The first factor (A) was the types of […]

Original Article
Soil phosphorus mobilization as affected by long-term organic fertilization in a tropical Regosol

Purpose: Phosphorus mobilization (PM) in tropical Regosols may be harmful to the environment and water quality. It is expected that high contents of soluble phosphorus in sandy soils may promote the P leaching through the transport of the available phosphorus from the soil surface to deeper layers. This study aimed to evaluate the PM in […]

Original Article
Comparative study of cucumber ( Cucumissativus L.) cultivars under organic fertilizer treatments in the Southern Guinea Savanna, Nigeria

Purpose: The study investigated the growth and yield of cucumber cultivars under the influence of the organic fertilizers application. Method: A 4 x 5 factorial combination of four cucumber cultivars (Poinsett, Marketer, Marketmore, and  Darina hybrid) and four organic fertilizers (Sunshine, Aleshinloye, Gateway, KWASU organic-based fertilizer-KOBF, and the control) in a completely randomized design at […]

Original Article
Bioconversion of kitchen waste by Pichia kudriavzeii SGP1 (Sudhida Gautam Parihar1)

Purpose: The study was undertaken with a purpose of at source bioconversion of wet kitchen waste.  To accelerate the “Zero Waste Concept” and meet the UN’s Sustainable Development Goals 2015. Method: Wet waste was mixed with dry paper, cardboard material and a microbial culture was inoculated in the bag. Proper mixing of the material enhanced […]

Original Article
Feasibility study of pilot scale vegetable waste composting project for Kundasang community’s waste management program

Purpose: Vegetable waste (VW) composting was assessed using a passive aerated pilot-scale composter at Kundasang, Sabah. The passive aerated composting system proposed at Kundasang Community Composting Site (KCCS) was analyzed for its techno-economic impact.Method: The composting performance (temperature, organic matter loss, moisture content, pH value, electrical conductivity, and nutrient value) of 500 ± 2 kg […]

Original Article
Exploring the synergistic effect of rose distillation waste and biostimulant beside other organic amendments onRosa damascena seedlings’ growth

Purpose: Floral waste, as a frequently overlooked resource for sustainable agriculture, can be harnessed to produce nutrient-rich soil amendments resulting in an enhancement of soil fertility and augment crop yields. This in turn can foster a circular economy, minimizing waste disposal and promoting a green economy. This study was aimed to explore the potential of […]

Original Article
Efficacy of vermicompost derived from local organic wastes as nursery sub-strates for cabbage and chili seedlings

Purpose: This study aimed to evaluate vermicompost derived from various local organic wastes as a nursery material for cultivating cabbage and chili seedlings, converting organic waste into fertilizer through vermicomposting. Method: Local organic materials, including cow dung, spent mushroom waste, and coffee grounds were utilized as the main substrates for earthworm bedding. Three main substrates, […]

Original Article
Nutrient availability in tropical soils fertilized with sewage sludge and natural phosphate

Purpose: The use of sewage sludge associated with natural rock-based fertilizers can increase nutrient solubility and soil fertility. From this perspective, this study evaluated changes in the chemical soil attributes and the nutrient availability rate after the application of sewage sludge, natural phosphate, and elemental sulfur in soils with different clay contents. Method: The study […]
