Purpose: The response of sweet sorghum to biosolids application under different irrigation regimes was studied in a field experiment conducted during 2010 and 2011 in Central Greece. The study assessed the effects of soil application of biosolids on plant height, biomass production, and water use efficiency. Method: The experiment consisted of nine treatments with three […]
Purpose Rice straw degradation in the soil is slow because of the high percentage of complex carbohydrates. Hence, farmers prefer to burn it in the agricultural field as a quicker alternative to the open burning of rice straw. Therefore, this study aims to characterize the bacteria from cow dung that can degrade rice straw. Method […]
Purpose: This study aimed to evaluate the effectiveness of starters made from cattle rumen and EM 4 on the decomposition of agricultural biomass wastes (rice straw, corncobs, and coffee husks). Method: Three types of starter i.e. starter from local cattle rumen (grass/straw feed), starter from the rumen of cattle farms (concentrate feed), EM 4 (factory […]
Purpose Maize (Zea mays L.) is a major crop grown and consumed in Nigeria but poor soil quality has resulted in low yield. This study assessed the quality of compost produced from agricultural wastes and its impact on the yield of Zea mays L. Method The composting process was carried out on a windrow (2 […]
Purpose No research has been published on the effect of chemical processing on the degradability and nutritional value of cumin residue. Chemical processing, such as urea, sodium hydroxide, and hydrogen peroxide, has been widely investigated to increase the nutritional value of grain residues, but information on cumin residue is limited. The effects of untreated and […]
Purpose Reusing agricultural waste as a substrate material for mushroom cultivation was considered a great alternative to bio-waste disposal. In this study, bamboo waste from a local skewer factory in Lampang Province, Thailand, was used as a substrate, along with the original material for the mycelial growth of Dictyophora indusiata mushroom. Method D. indusiata mycelia […]
Purpose: Fermented cow urine (cow bio urine) is used as an organic source of nutrients. This study aimed to determine the effect of various concentrations of cow bio urine as the organic nutrient source on the growth and yield of vegetable crops in hydroponic systems. Method: Research was conducted in a greenhouse at the University […]
Purpose This study investigated the effect of recycled Olive Pruning Residues (OLPR) and Spent Coffee Grounds (SCG) on substrate temperature (temp) and duration (dur) of Pleurotus ostreatus growing stages. This study also sheds light on the correlation between selected parameters, yield, and substrate composition. Method The experiment consisted of 2 sole substrates wheat straw (WS; […]
Purpose Diospyros mespiliformis which is commonly known as African ebony is a valuable fruit tree species with important medicinal and nutritional values. The tree has a slow growth rate that discourages its propagation and at present attempts made towards improving its growth performance are scanty. This study, therefore, evaluates the effect of the type and […]
Purpose The study was devoted to conceptualize, develop and evaluate a collector-cum-chopper for in situ paddy straw degradation at the farmer’s field level. The intention was to increase the amount of straw cut at size below 5 cm for nutrient recycling. Method A paddy straw collector-cum-chopper comprised of three sub-systems i.e. straw collection and conveying […]
Purpose Aggressive use of crop fertilizer during food production caused an overburden in the environment. Gradual release of crop nutrients from the fertilizer could decrease the massive utilization of fertilizer. The advantages are two folds, cheaper cost, and environmentally friendly crop production. Method Slow-release fertilizer was prepared by encapsulating hydroxyapatite (HA) with a single fertilizer. […]
Purpose: Sludge treatment and reuse as a fertilizer is of great significance in Gaza Strip. This study aimed to treat sludge generated at North Gaza WWTP, to produce rich nutrients fertilizer, to apply it in a greenhouse, and to compare its performance with different fertilizers. Method: The concept of drying beds was applied to 1500 […]
Purpose: Research investigated oil mill decanter cake (OPDC) and empty fruit bunch (EFB) from oil palm in varying forms as soil media for growth performances of cocoa (Theobroma cacao) and citrus (Citrus sp.) seeds during germination and growth. Method: Factorial design with 4 levels of bio-organic: oil palm decanter cake (OPDC) treated with hot water […]
Purpose: The purpose of the study was to find that solid waste from sago, tofu, and rice could be made into animal feed with high nutritional content as evidenced by increasing body weight of Gallus domesticus. Method: This research is a quantitative research using laboratory and field experimental methods to examine the proximate feed and […]
Purpose: Yam cultivation in soils of low fertility has been a major cause of yield decline in Nigeria. The inadequacies associated with either inorganic or organic fertilizer in the aspects of crop growth and productivity necessitated the introduction of organomineral fertilizers. However, information on the appropriate placement method for sustainable cultivation is still limited. Hence, […]
Purpose: This study was carried out with the aim of improving the use of compost products as compost tea and humic substances fertilizers, to study the evolution and the degree of compost maturity, and to use the chlorophyll as an indicator of compost quality. Method: The compost tea and humic substances were prepared from different […]
Purpose: Waste and waste disposal is a universal problem and attention is required in all ways. The plant generated waste (leaf litter) is also a type of organic waste that creates multiple issues in urban areas. Method: Vermicomposting is a suitable alternative safe, hygienic, and cost-effective disposal of organic solid waste with the help of […]
Purpose: This study analyzed the ability of Black Soldier Flies Larvae (BSFL) in reducing grease waste and the effect of variation in feed composition on the growth rate effect of larvae age at 8 days, 12 days, and 16 days. Method: Before reaching the specified age (8, 12, or 16 days), the larvae are fed […]
Purpose: Soil nutrient depletion is an endemic factor that constitutes one of the greatest limitations to crop production in the tropics. Identifying high yielding kale varieties that thrive best with the most cost-effective fertilizer type can help meet the nutritional deficits of most families in Africa in line with WHO recommendations. The propose of this […]
Purpose Composting is known since long for reducing the use of synthetic chemical fertilizers. These fertilizers are applied to the crops for the supply of required macro/micronutrients. The present study describes how to decompose biodegradable solid wastes quickly into compost without harming the environment. Method The microbial inoculums were developed from cow dung concentrate. The […]
Purpose Profiting from agricultural waste and lowering production costs for farmers have been made possible by the incorporation of bagasse and local resources as a substitute for sawdust. Method The experiment was using a CRD. Follows: Bagasse 100 % Bagasse: Rice straw (25:75%) Bagasse: Rice straw (50:50%) Bagasse: Rice straw (75:25%) Bagasse: Giant mimosa (25:75%) […]
