NPKS rates were 120 kg urea, 25 kg TSP, 50 kgs KCl, and 30 kg S/ha. N was applied 1/3 at planting and 2/3 5-7 d before panicle initiation. PKS were applied at planting. Six tonnes of rice straw or carabao manure/ha or 2 t rice straw ash or rice hull ash/ha were broadcast and incorporated just before planting. Treatments were in a randomized complete block design with four replications. One month after planting, the rice plants in all the treatments that received NPKS alone or with straw, carabao manure, straw ash, or hull ash were darker green, taller, and had more tillers than the control and the treatments without NPKS. Applying rice straw, carabao manure, rice straw ash, or rice hull ash did not significantly increase yield
