Influence of integrated nutrient management on dry matter accumulation and nutrient uptake in holy basil (Ocimum sanctum L.) as intercrop in coconut garden.

摘要

Field studies were conducted at Horticulture Research Station, Arsikere, Hassan District, Karnataka during 2007-08 to develop integrated nutrient management practices for holy basil as intercrop in coconut garden. Treatments include: T1, recommended practice (10 t FYM + 120:80:60 NPK kg/ha); T2, recommended NPK through fertilizers (120:80:60 NPK kg/ha); T3, 100% N through FYM; T4, 100% N through Vermicompost (VC); T5, 100% N through Composted Coir Pith (CCP); T6, 50% N through FYM + 50% NPK through fertilizers; T7, 50% N through VC + 50% NPK through fertilizers; T8, 50% N through CCP + 50% NPK through fertilizers. Dry matter accumulation was maximum with the recommended practice of 10 t/ha FYM + recommended NPK through fertilizers followed by integrated treatments of organic and inorganic source of nutrients and recommended NPK through fertilizers. The uptake of N, P and K by holy basil crop was found to be highest with the application of 50% N through FYM + 50% NPK through fertilizers followed by recommended practice of 10 t/ha FYM + recommended NPK through fertilizers. The organic carbon content in the soil was improved in all the treatments except recommended NPK through fertilizers and application of 100% N through CCP. The available N and K in soil were improved in the recommended practice of 10 t/ha FYM + recommended NPK through fertilizers and integration of 50% N through FYM/VC/CCP + 50% NPK through fertilizers. Improvement in available P in soil was observed in the recommended practice and application of 50% N through FYM/VC + 50% NPK through fertilizers.
