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.

Download or read book Differences in Dry Matter Yield and the Uptake Distribution and Use of Nitrogen by Sorghum Genotypes written by Goncalo Evangelista de Franca and published by . This book was released on 1981 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty-four sorghum (Sorghum bicolor (L.) Moench) genotypes were screened for differential response to N by growing plants with 10 mg N/ plant in nutrient solution. The genotypes TX 3934 X GH-8-17, and SC 423 X SC 239 produced the highest amount of dry matter per unit N (H), and SC 110 X SC 120, and SC 150-6 X SC 150-9 (L) produced the low-est amount of dry matter per unit N. Because of this, these genotypes were selected for further study to identify physiological properties that may be associated with differential N nutrition. The physiological properties evaluated in these genotypes were: (1) NO3 uptake rates as affected by time (hours after being put in a new N03 solution), N03 concentration, and plant age; (2) dry matter and N accumulation with plant age;(3) N distribution among plant parts at various plant ages; (4) dry matter produced per unit N; (5) genotype responses to different N levels and N compounds. Differential responses to N were moted among the genotypes screened with low N. The ranges were 131% for dry matter yields, 75% for N contents, 59% for top N/root N ratios, and 34% for dry matter produced per unit N. After an initial slow rate of N03 uptake, N03 absorption was relatively rapid during the next four hours before leveling off or decreasing after six hours in plants 34 days of age or younger; plants older than this showed no differences in N03 uptake. Patterns of N03 uptake with time suggested that uptake was induced by N03 at low concentrations. Differences in N03 uptake rates among (...).
