Book Description
Field experiment was conducted to evaluate the response of Cosor 3, BPI Sor 1 and UPLB SG 5 to varying nitrogen fertilization and plant population density under Central Luzon condition. The field experiment was conducted during the dry season (furrow irrigated) at the experimental farm of Central Luzon State University 9CLSU), while data processing was done at the University of the Philippines at Los Banos. The three levels of nitrogen fertilization were 50 kg N, 100 kg n

Book Description
Three grain sorghum cultivars were grown in the open field and under seven - and towo-year old rubber trees at there levels of nitrogen fertilizer and plant population density, to determine their performance in both seed and atoon crops in terms of grain yeild and other agronomic characters, quality perameters like protein and total starch content of grains and their effects on stem girth and latex yield of rubber. Comparing the six cultural environments with respect to the parameters evaluated, those grown in the open field and under two-year old rubber trees nanmely, MIT open field seed crop. MIT-open field ratoon crop, Kidapawan-under rubber seed crop and Kidapawan-under rubber ratton crop reduced the number of days to blooming, and gave higher grain and total dry matter yields, 100-grain weight and number of grains per panicle. The same treatments gave higher starch but lower protein content in the grains compared to those grown under seven-year old rubber trees namely. MIT-under rubber seed crop and MIT-under rubber ratoon crop. The u=yield component that was consistently associated with grain yield was number of grains per panicle. Nitrogen treatments increased grain yield, total dry matter yield, plant height, leaf area index and number of grains per panicle. Plant population density reduced leaf size and panicle length in both seed and ratoon crops in all environments. The cultivars showed a wide diversity of performance in different culturtal envivornments. There were as inverse relationships (...).

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.

Book Description
Applied Plant Virology: Advances, Detection, and Antiviral Strategies provides an overview on recent developments and applications in the field of plant virology. The book begins with an introduction to important advances in plant virology, but then covers topics including techniques for assay detection and the diagnosis of plant viruses, the purification, isolation and characterization of plant viruses, the architecture of plant viruses, the replication of plant viruses, the physiology of virus-infected hosts, vectors of plant viruses, and the nomenclature and classification of plants. The book also discusses defense strategies by utilizing antiviral agents and management strategies of virus and viroid diseases. With contributions from an international collection of experts, this book presents a practical resource for plant virologists, plant pathologists, horticulturalists, agronomists, biotechnologists, academics and researchers interested in up-to-date technologies and information that advance the field of plant virology. - Covers the detection, control and management of plant viruses - Discusses antiviral strategies, along with mechanisms of systemic induced resistance to enhance the defense of plants against viruses - Provides contributory chapters from expert plant virologists from different parts of the world
