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.

Moench) Cultivars Grown Under Rubber and in the Open Field as Affected by Nitrogen Level and Plant Density written by R.T. Gloria and published by . 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 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.
