Abstract


An investigation to evaluate the influence of system of rice intensification (SRI) on seed yield and quality in rice variety BPT-5204 was conducted at Agricultural Research Station (Paddy), Sirsi during kharif 2004-05. SRI method of cultivation, application of FYM and RDF significantly increased the number of tillers. The treatment combinations with SRI method showed more number of Productive tillers.  SRI method produced significantly higher (3.99 t ha-1) seed yield over traditional method. Although germination did not show significant variation among the methods of cultivation but vigour index recorded significantly higher values in SRI method. The 12 days seedlings produced more number of tillers per plant and productive tillers per plant.  Wider spacing of 40 x 40 cm found to have significant influence on growth parameters. The younger seedlings (8 days-old) flowered about four to five days earlier as compared to 25 days-old seedlings. Significantly higher seed yield per ha (3.19 t) was produced by 12 days seedlings. The treatment combination of 12 days old seedling with wider spacing recorded maximum seed yield per ha. The seeds produced by transplanting of 12 days old seedlings with wider spacing recorded significantly higher germination and vigour index values.
