Effect of municipal solid waste compost and NPK fertilizer on growth, yield and protein content of rice (cv. BRRI dhan49)

Abstract

An experiment was conducted to study the effect of municipal solid waste compost (MSWC) on growth, yield and protein content as well as to know the effect of combined application of MSWC and NPK fertilizers in rice (cv. BRRI dhan49). There were six treatments including- T0 = Control (No fertilizer or no MSWC); T1= 100% Recommended Doses of Fertilizers (RDF) NPK; T2 = (MSWC @ 5 t ha-1+ 75% RDF); T3= (MSWC @ 7. 5t ha-1+ 50% RDF); T4= (MSWC @ 10 t ha-1 + 25% RDF); T5 = (MSWC @ 10 t ha-1). The experiment was laid out in a randomized complete block design (RCBD) with three replications. Our results showed that the integrated application of MSWC and different RDF% had a significant impact on various plant growth and yield parameters including plant height, panicle length, number of effective tillers per hill, number of filled grains per panicle, 1000-grain weight (g), and grain and straw yield of rice. In case of T2 treatment, highest grain yield (5.70 t ha-1), straw yield (7.71 t ha-1) and protein content (5.875%) were obtained. Thus, the result indicated that combined application of MSWC with NPK performed better than the single application of either MSWC or NPK fertilizer.
