The effect of composted oyster mushroom baglog waste on rice growth and productivity in acid sulfate soils

Abstract

Indonesia demands appropriate land expansion for food production since the paddy fields are scaling down nevertheless the population is still increasing. Acid sulfate land has prospects for the development of agricultural areas. The land has a few obstructions in its use for paddy cultivation, including low nutrient availability, high Fe2+, content and acidity in soil. Compost that produced using baglog waste from oyster mushroom cultivation is relied upon to be an alternative soil enhancer in acid sulfate lands. The compost contains supplements required by plants (0.74% nitrogen, 0.50% phosphorus, 8.08% potassium, 14.38% organic carbon, and a pH of 8.00) which are potential for the amelioration of soil properties, plant growth, and productivity. Accordingly, this study aims to figure the effect of the application of composted baglog waste from cultivation of oyster mushroom on the growth and productivity of paddy in acid sulfate soils. This experiment utilized a single factor completely randomized design (CRD), as a different portion of the composted baglog waste b0 (0 ton.ha−1), b1 (5 ton.ha−1), b2 (10 ton.ha−1), b3 (15 ton.ha−1), and b4 (20 ton.ha−1). The outcomes showed that the application of composted baglog waste at a portion of 20 ton.ha−1 (b4) had the capacity to increase plant height, number of tillers, plant dry weight, weight of 100 grains, and paddy productivity, respectively by 24%, 115%. , 65%, 39%, and 66% contrasted with the control treatment (b0).
