Abstract:

A field experiment was carried out at S.G. College of Agriculture and Research Station, Jagdalpur, Chhattisgarh during Kharif 2016 to study the effect of organic and inorganic sources of nutrients on soil chemical properties and nutrient availabilities under direct seeded rice in Inceptisols of Bastar plateau zone. The experiment was conducted in randomized block design with twelve treatments and four replications. The 100% NPK i.e. recommended dose of fertilizers were 100:60:40 kg N: P2O5: K2O/ ha for rice crop. Soil samples were collected from the top soil surface (0-15 cm) of all the four replications before and after Kharif 2016 and analyzed for chemical properties and nutrients availabilities. The highest pH (6.70) was recorded in 50% NPK +5 t FYM + ZnSO4 @ 25 kg/ ha + lime 3 q/ha (T12) whereas the lowest pH (6.1) was recorded in 100% NPK. A slight increase in soil pH was observed in all the treatments which received FYM and lime and decrease was recorded in treatments which received inorganic nutrient sources as compared to the initial. The continuous application of organic materials along with fertilizers significantly increased the soil organic carbon as compared to the application of fertilizers alone. The use of organic manure like FYM with chemical fertilizers increased the availability of macro (N, P, K, S, Ca, and Mg) and micro (Zn) nutrients in soil over chemical fertilizer alone.
