Pablero, D.D. | Desamero, N.V.
In purely rainfed rice areas of Barangay [village] Rio Chico, General Tinio, Nueva Ecija, it is customary to use 120-160 kg/ha seeds in establishing wet direct seeding crop. Participatory adaptation cum techno-demo trials were conducted demonstrating the profitability of seeding rates, lower than 120 kg. The replicated on-farm trials for seeding rates of 40, 60, 80 and 120 kg/ha were established in 2013 wet season (WS) and 2014 WS with variety katihan 1 and PSB Rc 10, respectively. For cultural management, recommendations from Rice Crop manager were employed. The grain yields obtained in both trials did not vary significantly with seeding rate. Variations in yield components, however, were obtained. The values per square meter for number of seedlings at 7 (r=0.0031) and 31 (r=.0001) days after seeding (DAS), number of tillers at 31 (r
