Household Waste Based Vermicompost and Fertilizer Effect on Yield and Attributes of Pot Culture Rice (Oryza sativa)

Abstract

Organic matter content in soil improves the soil health with supporting large microbial population and stabilizing soil health deterioration. The soil physical, chemical parameters improve according to the significant application of organic matter in soil. Integrated application of organic and inorganic sources and analysis of these components in response to its effect on rice growth and yield attributes at different stages is of major concerned study. Application of four levels of vermicompost (0 t ha-1, 1.25 t ha-1, 2.5 t ha-1, 3.7 t ha-1) and three levels of fertilizer (0%, 100%, 50% Recommended Dose of Fertilizer) were taken in a pot culture experiment and total of 36 pots i.e. twelve treatments replicate thrice for analyzing its effects on growth and yield attributes of rice crop (Variety-Rajendra Bhagawati) with using factorial Completely Randomized Design statistical method for data analysis and validation. Application of higher doses of vermicompost 3.7 t ha-1 and higher dose of fertilizer i.e. 100% RDF content in combination produced elevated grain and straw yield and also boosted growth attributes (Panicle length, test weight, number of tillers, grains per panicle), root volume as well as chlorophyll content from initial growth up to the harvesting time over the control due to buildup of organic matter and nutrient mobilization in soil.
