Abstract
Field experiment was conducted to evaluate the response of Cosor 3, BPI [Bureau of Plant Industry] Sor 1 and UPLB [University of the Philippines at Los Banos] SG 5 to varying levels of nitrogen and plant plantation densities under Central Luzon conditions. The levels of nitrogen were 60, 100 and 150 kg per hectare. The population densities used were 200,000, 250,000 and 300,000 plants per hectare. The computed grain yield per hectare of the three varieties was highest at 150 kg N per hectare (14.1 tons) and lowest at 50 kg N per hectare C9.0 tons). Grain yield also increased as plant population was increased from 200, 000 (9.7 tons) to 250,000 (2.0 tons) plants per hectare. Yield did not increase beyond 250,000 plants per hectare. Incremental nitrogen increased panicle length, weight, and grain yield per panicle. These yield components de;reased, however, with increasing plant population in all the three varieties. Blooming period was shortened by increasing nitrogen but not by plant population. Plant height was not significantly affected by both nitrogen fertilization and plant population.
