e0“Field experiments were conducted at Sivapuri, Chidambaram, Tamil Nadu to evaluate the efficacy of vermicompost, in comparison to inorganic fertilizers-NPK, on the physio-chemical and biological characteristics of the soils--clay loam soil (CLS) and sandy loam soil (SLS) and on the growth, yield and nutrient content of beans--Phaseolus vulgaris”
e1“Results showed that the application of vermicompost @ 5 tonnes ha(-1) had enhanced significantly the pore space (1.09 and 1.02 times), water holding capacity (1.1 and 1.3 times), cation exchange capacity (1.2 and 1.2 times)”
e2“It reduced particles (1.2 and 1.2 times), and bulk density (1.2 and 1.2 times), pH (1 and 1.02 times) and electrical conductivity (1.4 and 1.2 times)”
