This book was released on 1971 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: A. Grain sorghum - 1966 and 1967. The effects of plant spacing on yield and yield components of RS610 hybrid grain sorghum were studied in 1966 and 1967 at Urbana, Illinois. Grain yield/plant was, as expected, reduced in all experiment as plant population was increased. Plants at low populations were able to compensate somewhat for low stand densities through production of tillers. More tillers were produced in narrow than in wide rows in one of the two experiments conducted in 1966. A generally higher/seed at low than at high plant population increased yield/plant at low population. In spite of tillering which increased the number of seeds/plant and production of heavier seeds by plants at low stand densities, yield/m2 increased as plant population increased to between 25-48 plants/m2, depending on the experiment. While RS610 hybrid grain sorghum has been noted for its high capacity to tiller, the results of these experiement indicate that it lacks the potential to produce a sufficient number of tillers/plant and/or seeds/panicle to offset low planting rates at Urbana, Illinois. Per plant yield from a study utilizing a systematic planting design, in which observations were single systematically arranged plants, were similar to those obtained in a large plot experiment. Small per plant difference were magnified, however, when they were multiplied by the number of plants/m2 so that predicted yield/m2 from the systematic study did not correspond closely to those obtained in the large plot experiment.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Prior studies indicate clumped planting can increase grain sorghum yield up to 45% under water deficit conditions by reducing tiller number, increasing radiation use efficiency, and preserving soil water for grain fill. The objective of this study was to evaluate effects of planting geometry on sorghum grain yield. The field study was conducted in seven environments with two sorghum hybrids, four populations, and two planting geometries. Crop responses included leaf area index, yield, and components of yield. Delayed planting decreased yield by 39%, and a later maturing hybrid increased yield, relative to an early hybrid, by 11% under water sufficiency. Clumped planting increased the fraction of fertile culms (culms which formed panicles) from 5-14%. It reduced the number of culms m−2 by 12% under water limiting conditions (at one of two locations) but increased culms m−2 16% under water sufficiency. Seeds per panicle and seed weight generally compensated for differences in panicles m−2, which were related to different planting population densities. Although agronomic characteristics of hybrids varying in maturity have been widely studied, little information exists concerning their physiological differences. Therefore, the objective of the greenhouse study was to determine if stomatal resistance, leaf temperature, and leaf chlorophyll content differed between two DeKalb grain sorghum [Sorghum bicolor (L.) Moench] hybrids. They were DKS 36-16 and DKS 44-20, of medium-early and medium maturity, respectively, when grown under field conditions in Kansas. Seeds were planted in a greenhouse. Stomatal resistance and leaf temperature were measured 55 days after planting with a Decagon Devices (Pullman, WA) diffusion porometer, and chlorophyll content was measured 119 days after planting with a Konica Minolta (Osaka, Japan) SPAD chlorophyll meter. The two hybrids did not differ in stomatal resistance, leaf temperature, chlorophyll content, height, and dry weight. Their difference in maturity was not evident under the greenhouse conditions. Future work needs to show if hybrids of different maturities vary in physiological characteristics.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In Kansas, productivity of grain sorghum [Sorghum bicolor (L.) Moench] is affected by weather conditions at planting and during pollination. Planting date management and selection of hybrid maturity group can help to avoid severe environmental stresses during these sensitive stages. The hypothesis of the study was that late May planting improves grain sorghum yield, growth and development compared with late June planting. The objectives of this research were to investigate the influence of planting dates on growth, development, and yield of different grain sorghum hybrids, and to determine the optimal planting date and hybrid combination for maximum biomass and grains production. Three sorghum hybrids (early, medium, and late maturing) were planted in late May and late June without irrigation in Kansas at Manhattan/Ashland Bottom Research Station, and Hutchinson in 2010; and at Manhattan/North Farm and Hutchinson in 2011. Data on leaf area index, dry matter production, harvest index, yield and yield components were collected. Grain yield and yield components were influenced by planting date depending on environmental conditions. At Manhattan (2010), greater grain yield, number of heads per plant, harvest index, and leaf-area were obtained with late-June planting compared with late May planting, while at Hutchinson (2010) greater yield was obtained with late May planting for all hybrids. The yield component most affected at Hutchinson was the number of kernels panicle-1 and plant density. Late-May planting was favorable for late maturing hybrid (P84G62) in all locations. However, the yield of early maturing hybrid (DKS 28-05) and medium maturing hybrid (DKS 37-07) was less affected by delayed planting. The effects of planting dates on growth, development, and yield of grain sorghum hybrids were found to be variable among hybrid maturity groups and locations.

This book was released on 1975 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 (...).

This book was released on 1975 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
