Four field experiments were conducted over the 1992 and 1993 seasons (southwest monsoon seasons, June-October) in the warm subhumid tropical region on the west coast of the Maharashtra State, India. The objective was to investigate the effect of recycling limited amounts of rice straw (RS) (as a source of K and Si) integrated with the use of prilled urea (PU) and urea briquettes (UB) at 60 kg N/ha on the growth and yield of rainfed transplanted rice (Oryza sativa L.). The management practice, consisting of basal incorporation of RS (2 t/ha) integrated with deep placement of UB (one 2-1-g UB/4 hills) immediately after transplanting using a modified 20 x 20 cm spacing, produced a significantly higher grain yield (average increase of 1-3 t/ha) and straw yield (average increase of 1 • 1 t/ha) than did the RS practice integrated with two equal split applications of PU at the same N rate and hill spacing. The additional yields were attributed to the increase of total and productive tillers/m 2 and panicle weight. The results indicate the potential of the integrated RS-UB management for increasing yields of rainfed transplanted rice in the warm subhumid tropical zone.
