Abstract

The study was conducted to determine the growth and yield response of Oryza sativa CL1 and the ideal rate of Nostoc commune to be applied as fertilizer supplement. Based on the result of the study, application of 3 g of N. commune + ½ recommended rate of inorganic fertilizer (RRIF) gave the best response among the treatments in terms of the plant height, number of tiller and harvest index. With respect to weight of 1000 grains and the days to flowering, application of 9 g of N. commune + ½ RRIF was the best treatment. Moreover, concerning the number of productive tillers, days to maturity, chlorophyll content, filled grain percentage per panicle, grain yield per hectare, harvest index and biomass application of full RRIF appeared desirable. Regarding the growth and yield parameters of CL1, application of full RRIF was recommended. However, there is a need to verify further the response of CL1 to the application of the different rate of N. commune + ½ RRIF, especially the 3 g of N. commune + ½ RRIF, for it can increase the yield through continuous application.
