Way of compost application for organic farming

Abstract

Application of composts is an alternative of synthetic agrochemicals for eco-friendly farming. Work is limited on the effective and economic way of compost application in Bangladesh. A study was done at the Field Science Center, Saga University, Japan with green tea waste – rice bran compost (GRC) application. Radish (Raphanus sativus L.), spinach (Spinacia oleracea L.) and komatsuna (Brassica rapa var. pervidis) were used as test plants. GRC was applied at 1.0 kg m-2 by mulching on soil after seeding. It enhanced seed germination, seedling growth and improved crop yield of spinach and radish grown in a controlled condition. Among the two application methods, post-sowing mulching (PSM) reduced water loss from upper soil surface, thus enhanced seed germination and better growth compared to pre-sowing incorporation (PSI) system. This study also suggests that improper compost incorporation to soil may impair seed germination, seedling growth and likely crop yield.

Influence of compost Amendments on the germination and Growth performance of Zea mays L.

“…Moreover, application of compost manure at either 5 or 10 t/ha supported maximum maize grain yield (Kandil et al 2020). Khan et al (2019) reported that compost application (10t/ha) as mulch after seed sowing enhanced germination, seedling growth, crop productivity, and quality of spinach and radish under controlled conditions. The discrepancies in the results of the studies could be attributed to differences in compost type, which influenced the chemical composition (OC, TN, AP, and AK) of the amendments, and consequently biomass yield.…”

Productivity and flower quality of different pot marigold (Calendula officinalis L.) varieties on the compost produced from medicinal plant waste

“…Composting is recommended as a tool for managing and controlling diseases, pests, and weeds. In organic production, it is desirable that all organic waste from the farm is composted and as such returned to the soil as technologically mature compost (Khan et al, 2019). Such compost has significant commercial potential in horticultural production of flowers, vegetables, and medicinal plants, primarily in container production of seedlings (as an integral part of substrate mixtures), but also, in field conditions, where it can be achieved by using compost produced in the medicinal plants production (Khalid and da Silva, 2012).…”
