Abstract:
A field experiment was conducted in the Thamirabarani tract of Tamilnadu during pishanam season of 2018-2019 to study the effect of different INM practices on soil fertility, rice productivity and profitability in a sandy clay loam soil, Thamirabarani tract of Tamilnadu. The experiment was laid out in a randomized block design with 9 treatments and 3 replications. The results revealed that among the different INM practices STCR-IPNS along with application of biofertilizers on 15th& 30th days after transplanting recorded the highest productivity and profitability, followed by STCR-IPNS with basal application alone treatment. The same treatment recorded the highest yield (7.70 t haˉ¹) as well as nutrient uptake besides profitability (Rs.386 haˉ¹ dayˉ¹) over the other treatments. The yield attributes were also improved by the same treatment. The STCR-IPNS treatment with biofertilizers (basal, 15th& 30thDAT) improved the soil available nitrogen, phosphorous, potassium and organic carbon after the harvest. The same treatment recorded the highest net return of Rs.42,436 haˉ¹. Among the INM treatments 75 % RDF + GLM @ 6.25 t ha¯¹ + biofertilizers- (basal 15th& 30th DAT) recorded the lowest net return of Rs.32,356 haˉ¹.
