Vermicompost as an Alternative to Inorganic Fertilizer to Improve Okra Productivity in Côte d’Ivoire

The quality of vermicompost from various sources composted with earthworm Perionyx excavates

“…This might be associated with the aggressiveness of the earthworm Perionyx excavates in decomposing organic matter from animal waste [27]. The animal waste was consumed by the earthworm so that it underwent decomposition assisted by soil microorganisms in the digestion of the earthworm, then animal waste was removed from the digestive tract in the form of vermicompost [1] [28]. Soil microorganisms in the digestion of earthworms decompose organic matter from animal waste and release CO 2 so that there is a decrease in organic C content.…”

“…The results of the analysis of variance showed that the mean pH (H 2 O, 1:5 w/v) of the 4 types of animal manure (cow, buffalo, chicken, and goat) were significantly different, as presented in Table 4. The increase in pH (H 2 O, 1:5 w/ v) of the vermicompost is related to the formation of NH 4 + compounds which are more dominant than the formation of organic acids derived from the activity of microorganisms in the digestion of the earthworm Peryonix excavates during the decomposition of organic matter [1].…”

“…Those are aims of vermicomposting: 1) to improve the physical (like soil porosity, aeration, soil aggregation), chemical (pH, cation exchange capacity, available nutrients), and biological (organic carbon and beneficial microorganism ) properties of the soil [1], [2], [3], [4]; 2) to provide higher N, P, and K contents than compost [5], [6], [7]; 3) to improve marginal soil quality and maize production [2]; 4) to contain a lot of soil living organisms [8]; 5) to increase water absorption and water storage [9]; 6) are environmentally friendly and free of plant pests and diseases [10]; 7) to serve as a soil 1005 (2022) 012006 IOP Publishing doi:10.1088/1755-1315/1005/1/012006 2 conditioner [11]; 8) requires a relatively short time to manufacture; 9) easy way to produce; 10) to increase agricultural productivity of many crops [1], [12], 11) to produce more hormone with accelerating plant growth [13]; [14].…”

Production Efficiency, Water Productivity and Monetary Efficiency of Okra Under Organic Manure and Biofertilzers Application

“…) and control, respectively. Vermicompost is rich in plant macro and micronutrients and beneficial soil microbes and plant growth promoting compounds like growth hormones therefore its application in agriculture enhance plant growth and yield [9,10]. Beside these, vermicompost also improves soil physical (soil bulk density, water holding capacity) and soil chemical properties (pH, and electrical conductivity) than conventional compost [11].…”

Effect of Food Waste Compost (FWC) and its Non-Aerated Fermented Extract (NFCE) on Seeds Germination and Plant Growth

“…Considering composting, the term itself refers to the process of controlled biological maturity under aerobic conditions, where organic matter is decomposed by microorganisms such as fungi and bacteria, to materials with low molecular weight, stable, hygienic, humus-rich, and beneficial both for the agricultural crops and for soil organic matter recycling [15] [19]. The compost is a sustainable, economic, and a feasible way to efficiently utilize nutrients from pre and post-consumers food waste as vegetative wastes from modern agriculture.…”
