Book Description
Grain sorghum (Cosor 3) was grown under three light regimes, i.e., in full sunlight, 25% shade, and 50% shade at three levels each of nitrogen and plant population density to evaluate its yield and other, important characteristicssuch as: leaf lenght, leaf width, leaf area index,100-grain weight, grains per panicle, panicle yield, grain-stover ratio, threshing percentage, total dry matter production, panicle lenght, plant height and number of days to blooming. In addition, leaf nitratereductase activity and grain tannin concentration were analyzed. Plantpopulation densities used were 150, 000, 200, 000 and 250,000 plt/ha; the nitrogen levels at 0, 75, and 150 Kg N/ha; and 0, 25, 50 per cent shading. The statistical design split-split plot was used with plant population density as the main plot, nitrogen level as the sub plot, and light intensity as the sub-sub plot. The experiment was conducted during the dry season (January-April, 1975) at the Central Experiment Station, University of the Philippines at Los Banos, Laguna. The yielding capacity of grain sorghum (Cosor 3) in terms of its total dry matter,grain yield, and grain tannin concentration was reduced at low light intensyti. The results have shown that: l. Grain sorghum (Cosor 3) yielded differently at different combinations of plants density, nitrogenlevels, and light intensity. 2. Increasing plant population density up to 250,000 plt/ha consistently resulted in reduction of such characters as: leaf length, leaf width, plant height, and number of grains perpanicle. In spite of the depressive effects of dense population on individual plants, grain yield is co compensated by the increase in number of panicles per unit area. Higher plant population density is advantageous only at high light intensity, while at lower light intensity lower plant population is preferred. 3. Fertilized plants matured 10 days earlier than the unfertilized. Plants treated with 150 Kg N/ha produced higher grain yield at higher light intensity. Under shaded condition, grain yields from 75 and 150 Kg N/ha were comparable. 4. Grain tannin concentration was lower at high nitrogen rates. At high light intensity, grain tannin concentration was also high. 5. Leaf nitrate reductase activity was maximum at 25% shade and ao lower nitrogen level. At higher nitrogen rates, maximum nitrate reductase activity was obtained from the unshaded plants.
