Aim: The aim of study was to evaluate the influence of various organic and
inorganic nutrient sources on physico-chemical and microbiological properties
of acid Inceptisol after cabbage (Brassica oleracea L. var. capitata) harvest.
Method and Materials: Eight different combinations of doses of Farm Yard Manure (FYM), Vermicompost (VC) and recommended doses of NPK fertilizers (RDF) such as control (T1), 100 % RDF (T2), 100 % N through FYM (T3), 100 % N through VC (T4), 50 % RDF + 50 % N through FYM (T5), 75 % RDF + 25 % N through FYM (T6), 50 % RDF + 50 % N through VC (T7) and 75 % RDF + 25 % N through VC (T8) were tested in RBD and replicated thrice. The experimental soil was having pH 4.87, SOC 1.24 %, Alkaline KMnO4- N 160 kg/ha, available P2O5 18.60 kg/ha and available K2O 238.4 kg/ha.
Results: The results revealed that the higher soil dehydrogenase enzyme activity (DHA) and soil microbial biomass carbon (SMBC) was observed under all organic manures treatments over the control and sole inorganic treatments. Among the organic treatments, T3 (100 % N through FYM) recorded highest DHA and SMBC. In both combined treatments, farm yard manure treated soils (T5 and T6) showed higher DHA and SMBC over vermicompost treated soils (T7 and T8) indicating superiority of FYM over VC in maintaining soil biological health after harvest of cabbage.
Conclusion: The application of 50
per cent nitrogen through vermicompost along with 50 per cent of the
recommended dose of fertilizers (T7) found most effective
combination.
