Analyzing Impact of Vermicompost in Various Combination With Chemical Fertilizers on Physico-chemical Propertif.s of Soil and Wheat Crop

Abstract

To minimize the use of chemical fertilizers in crop production, and to explore the possibility of application of organic fertilizers for sustainable agriculture. the experiment was conducted at the Crop Research Center of Sardar Vallabh Bhai Patel L niH:r~it' nl Agriculture & Technology. Meerut (U.P.) during 2005-06 and 2006-07 In · the experiment live different raw material "ith Ei.~enia foetida were us.:d to prepare vermicompost On the basis of chemical composition, best vermicornpost \\as sd.:cted for further study. Significant effect of different treatments of vermicornpost on physicochemical properties on soil and plant growth was found. All the plant gro" th parameter) at different days interval were found significantly higher with the application of vem1icompost@ 3.0 t ha'1 with I 00% NPK as well as 75% NPK@ 3.0 t ha 1 dunng both the years. Biological, grain and straw yields of wheat were influenced significantly by various treatments. Application of vermicompost alongwith chemical fertilizers. incr~as~s concentration of nutrients (macro and micro) in grain and stra'' as well as uptake b) \\heat Improvement in soil physico-<:hemical properties bulk dcnsit:.

Similarly increasing the doses of NPK within same dose of vermicaornpost resulted significantly higher nutrient status in soil and plant. Comparison of various parameters like gro\\1h, yield, plant nutrient cont.:nt ami nutrient uptake by plant etc., revealed that T7 (75% 1\PK with vcrmicompo>t '" '1 0 t h,1 1) was found statistically similar to T10 where I 00% NPK with vcrmicompost al 1.0 t ha 1 was applied during both the years. This implies that application of 3.0 t ha 1 or vermicompost along with 75% NPK is a better combination tor op1imum crop) icld. I h1s combination also enhanced the soil health by improving avai lability of different nutrient as well as physico-chemical properties of soil.
