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.

Available in PDF, EPUB and Kindle. Book excerpt: Seeds of seven hybrid and open pollinated sorghum cultivars were separated with sucrose density solutions into four specific gravity (SG) classes for studies on the effects of seed SG on field performance. The seeds were planted at different densities to provide three levels of competition: "normal" planting density; one high and one low SG seeds in the same hill; and single seeds in widely spaced hills, no competition. There were no differences among the high, medium-low and unseparated (control) seed SG treatments for emergence, vegetative and reproductive development for the normal density plantings. Yield, however, was significantly lower for plants of the unseparated (control) seeds as compared to the SG separated seeds. When high and low SG seeds were planted in the same hill, emergence of the high SG seeds was higher and they produced more vigorous plants that produced more tillers, matured earlier and yielded more as compared to those from low SG seeds. In the case of high and low SG seeds planted at non-competitive spacing, emergence, plant height, number of tillers and yield were higher and the number of days to panicle exsertion and anthesis were fewer for the plants from the high SG seeds as compared to those from the low SG seeds. Priming of high SG seeds did not enhance plant performance above the level of the high SG unprimed seeds. Seed SG was greatly affected by the degreee of weathering and immaturity. As the degree of weathering or immaturity increased, the percentages of seeds in the two highest SG classes sharply declined, while those for the two lowest SG classes sharply increased. Seeds from the intense weathering treatments exhibited cavitation and profuse fungal growth in the placental sac area and in the embryo. Similar cavitation was observed in seeds from the immaturity treatments. Differences in the speed of germination among the unweathered, mature, high SG seeds appeared to be related to differences in permeability of the pericarp to water and/or oxygen.

This book was released on 1971 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid grain sorghum seeds were aged artifically for 0, 3, 5, 7, and 11 days at 42oC and 100% RH, wich produced high, medium, low and lowest vigor level. Among the various laboratory tests performed, standard germination and field mergence, were the least sensitive in discerning the physiological condition of the seed lots. The speed of germination more accurately differentiated the degree of deterioration of the seed lots and was closety correlated to yield. Adverse effect of planting low vigor seeds was found to be related to plant height, panicle exsertion, anthesis, tillering capacity, length of the panicle, and yield. Less vigours seeds produced plants which were not able to "catch up" to the vigorous ones. These slow growing plants were significantly inferior in panicle exsertion to those produced from more vigorous seeds. Seeds aged for 7 and 11 days had their process of exsertion delayed for about 2 and 3 days, respectively. Anthesis, conseguently, was also significantly retarded. Tillering capacity of plants produced from low vigor seeds was significantly reduced, as well as grain yield. Primary head yield was also significantly reduced about 14% for the more deteriorated seeds, and 12% for the mixed treatment, as compared to the control. Yield reductions of 9, 4, and 3% were also detected in seeds aged for 7, 5, and 3 days, respectively, as compared to the check. Seed moisture content generally increases as the vigor level decreased, indicating that the process of maturation was delayed as a (...).

This book was released on 1972 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field experiments were conducted at the University of Arizona Experiment Farm at Marana, Arizona, in 1970, to determine the effects of four plant populations on yield and agronomic characteristics of the cotton (Gossypium hirsutum L.) cultivar "Deltapine 16" and the grain sorghum[Sorghum bicolor (Linn.) Moench] hybrid "DeKalb A25". Significant differences in seed cotton yield due to plant populations were found. Boll size, lint percent, lint index, seed index, seed per boll, fiber length (upper half mean), fiber strength, fiber fineness, and plant height were not significantly affected by plant population. The efficiency of mechanical harvesting increased with plant population. No significant differences were found in grain sorghum yield due to the plant populations used in this test. Plant height, heads per plot, and seed index increased with plant populations, but head weight, yield per plants, heads per plant, and seed moisture content decreased. Plant population did not affect trash percentage with the combine used in this experiment.
