Abstract:
A field investigation was carried out during kharif 2019 at Agricultural Research station, Binjhagiri, Chatabar, Faculty of Agricultural Sciences, IAS, SOADU, Bhubaneswar to study growth and yield of black rice (Oryza sativa L.) varieties as influenced by different organic amendments under “SRI” (System of Rice Intensification) method of cultivation. The experiment was laid out in factorial randomized block design with three replications. Treatments consisted of two varieties (V_I- Chaka Hao Amubi and V₂- Kala Malli) in main plot and six practices of organic amendments (T_I - Jeevamrutha, T₂ – Jeevamurtha + Vermicompost, T₃- EM-1, T₄ - EM-1 + Vermicompost, T₅- Jeevamurtha + EM-1 and T₆- Vermicompost) in subplot. Study revealed that among the varieties, Kala Malli performed well and produced significantly the highest yield of grain and straw. The increase in grain yield was associated with significantly higher Number of filled grains panicle^-1, Ear bearing tillers m^-2, and test weight. Among the organic amendments, T₄ - EM-1 + Vermicompost recorded highest yield of grain & straw over others treatments.
