Available in PDF, EPUB and Kindle. Book excerpt: Sorghum experiments were conducted at the Central Experimental Station, University of the Philippines at Los Banos, College, Laguna after the lowland rice was harvested during dry season 1977 with the following objectives: (1) to determine the grain yield of the selected grain sorghum cultivars grown after rice; (2) to evaluate the main and combined effects of tillage and populations densities on yield amd other agronomic characters of grain sorghum; (3) to study the response of selected grain sorghum cultivars to nitrogen levels with and without phosphorus; and (4) to correlate the leaf area index and grain yield. Regardless of the 3 rates of planting used, tillage practices did not have any significant effect on grain yield and other agronomic charactersfor both varieties tested. However, population densities significantly affected the leaf area index, plant height and grain yield. Population density of 300,000 plants/ha was better than 200,000 and 250,000 plants/ha. Application of nitrogen fertilizer increased plant height, leaf area index, number of grain per panicle and grain yield, but reduced the growth duration and 1000 grain weight. Phosphorus application together with nitrogen further improved the grain yield and other agronomic characters o fsorghum. Application of 150 kg N/ha together with 50 kg P2O5/ha was found the best among the different fertilizer treatments used. Leaf area index had significant positive correlation to grain yield. The bigger the leaf area index at blooming stage, the more(...).
