Book Description
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 (...).

Book Description
Sorghum is among the top five cereals and one of the key crops in global food security efforts. Sorghum is a resilient crop under high-stress environments, ensuring productivity and access to food when other crops fail. Scientists see the potential of sorghum as a main staple food in a future challenged by climate change. The contributors provide a comprehensive review of sorghum knowledge. The discussion covers genetic improvements, development of new hybrids, biotechnology, and physiological modifications. Production topics include water and nutrient management, rotations, and pest control. Final end uses, sorghum as a bioenergy crop, markets, and the future of sorghum are presented. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.

Book Description
This new volume, Advances in Sorghum Science: Botany, Production, and Crop Improvement, provides an easy-to-read and comprehensive treatment of the sorghum crop. With the world’s production of sorghum topping over 55 million tons annually, sorghum is very important for as a staple dietary food for much of the world as a rich source of micronutrients and macronutrients, as an ingredient in the processing of many foods, and as a source of fodder. The authors of the volume provide detailed information on sorghum from several disciplines and bring together recent literature under one umbrella. The book covers the various aspects of the sorghum crop, starting from its origin, to its domestication, and going on to biotechnology of the crop. It describes sorghum production, ideotypes, botany, physiology, abiotic and biotic factors affecting crop productivity, methods of cultivation, postharvest management, grain quality analysis for food processing, improvement of sorghum crop, and research advancements in breeding and biotechnology. This valuable resource will be helpful to researchers and scientists working to understand the relation between various disciplines and the implementation of new methods and technology for crop improvement and higher productivity. The multi-pronged approach will help to enable the increase sorghum productivity to meet the world’s growing demands.
Some Genotypic Variation in Sorghum (Sorghum Bicolor (L.) Moench) Seed Related to Germination Temperature and Water Absorption

Book Description
Seed of 36 sorghum (Sorghum bicolor (L.) Moench) geneotypes selected on the basis of high physiological quality were evaluated to determine genotypic differences in response to germination temperatures ranging from 10 to 42C. Seed of high, medium, and low quality were evaluated to investigate seed quality-germination-tempearture relationships. Seed of 24 genotypes were dimensionally sized and permitted to imbile water to evaluate both genotypic variation in speed of water uptake and the influence of seed size on water imbibition. Sorghum seed of near maximum phusiological quality germinated equally well at temperatures between 20 and 30C. Among the range of genotypes evaluated, constant germination temperatures of 14 and 42C were the best for screening genotypes for their to germinate at low and high temperatures, respectively. Two genotypes, IS 1166C and SC 175-14, were equal to or better than all other genotypes at all germination temperatures evaluated. Five genotypes, E 35-1, MN 1958, MN 4508, IS 12685C and TPDXB1388 (9256) were very sensitive to germination temperatures outside the optimal range. Seed of lower physilogical quality were more sensitive to germination temperatures than those of high quality. However, there was a differential response among the genotypes. Regardless of genotype, small seed increased in moisture content more rapidly than large seed when water supply was not limited. Within the same size. there was genotypic varation both in the rate of moisture absorption and the time (...).
