Abstract:
The field experiment was carried out at Agricultural College and Research Institute, Killikulam as summer rice in 2021-2022 for the management of nutrients in wet seeded rice by using the combination of both organic and inorganic sources of nutrients. The different nitrogen sources utilized in the experimental study were STCR based N application through conventional urea, liquid Nano urea as foliar spray at critical stages of rice and Bio Organic Fertilizer (BoF). The BoF was prepared by the combination of Rice Husk Biochar (RHB), vermicompost, rock phosphate and microbial consortia. The combination of both organic and inorganic source of nutrients excelled over the other treatments. The treatment combination of STCR-N, Liquid nano urea as foliar spray and Bio Organic fertilizer (BoF) (T₁₃) has the more plant height, a greater number of productive tillers, greater yield and higher B:C ratio among the other treatments.
