Book Description
Cotton production today is not to be undertaken frivolously if one expects to profit by its production. If cotton production is to be sustainable and produced profitably, it is essential to be knowledgeable about the growth and development of the cotton plant and in the adaptation of cultivars to the region as well as the technology available. In addition, those individuals involved in growing cotton should be familiar with the use of management aids to know the most profitable time to irrigate, apply plant growth regulators, herbicides, foliar fertilizers, insecticides, defoliants, etc. The chapters in this book were assembled to provide those dealing with the production of cotton with the basic knowledge of the physiology of the plant required to manage the cotton crop in a profitable manner.

Book Description
Stand establishment and early vigor are critical to the successful production of cotton. However, there is a lack of information on the genetics and the physiological mechanisms determining early vigor. Physiological and genetic aspects of resource allocation by cotton plants in the time period between emergence and first bloom need to be examined. As an initial step, early vigor among modern cultivars and advanced breeding lines were compared. In addition, the effect of seed source (parent plants grown in Arkansas or Arizona) on seedling vigor were compared. Various traits, including leaf area development and shoot dry weight, root dry weight (greenhouse only) were measured under field and greenhouse conditions. In two field seasons, seeds produced in AZ had greater shoot dry weight early in development than seeds produced in AR, which may have been caused by differences in seed weight. Advanced breeding lines, regardless of seed source, exhibited greater shoot dry weight than commercial seeds. However, the differences in seedling biomass between seed source were reduced as plants developed. Several genotypes had consistently superior or inferior shoot dry weights in both years despite different environmental conditions. Characteristics closely associated with seedling biomass were seed dry weight, cotyledon area and dry weight, and area and dry weight of the first leaf. As expected, the associations of cotyledon and first leaf area with traits measured at later harvests were reduced. These data suggest that the area of the cotyledons and the first leaf are important drivers for early growth in cotton.

Book Description
Seed quality is one of the most important factors for stand establishment in cotton (Gossypium Sp.), and the use of good quality seeds is therefore essential to obtain an optimum plant population. Conditions prevailing during seed formation can affect the quality of seed produced, and hence crop establishment in the next growing season. These conditions can affect the germination of the seeds and the ability of the seedlings to emerge from soil. Field experiments were conducted to investigate the effect of nitrogen (N), phosphorus (P), potassium (K), foliar application of zinc (Zn) and calcium (Ca), the use of plant growth retardants (PGR) [e.g., 1, 1-dimethyl piperidinium chloride (MC); 2-chloroethyl trimethyl ammonium chloride (CC); or succinic acid 2, 2-dimethyl hydrazide (SADH)], during square initiation and boll setting stage, on growth, seed yield, seed viability, and seedling vigor of Egyptian cotton (G. barbadense). Dry matter yield, total chlorophyll concentration, K, Zn and P-uptake plant-1, were increased with the addition of K, and foliar application of Zn, and different concentrations of P (576-1728 g ha-1of P).

Book Description
Crop Physiology: Case Histories of Major Crops updates the physiology of broad-acre crops with a focus on the genetic, environmental and management drivers of development, capture and efficiency in the use of radiation, water and nutrients, the formation of yield and aspects of quality. These physiological process are presented in a double context of challenges and solutions. The challenges to increase plant-based food, fodder, fiber and energy against the backdrop of population increase, climate change, dietary choices and declining public funding for research and development in agriculture are unprecedented and urgent. The proximal technological solutions to these challenges are genetic improvement and agronomy. Hence, the premise of the book is that crop physiology is most valuable when it engages meaningfully with breeding and agronomy. With contributions from 92 leading scientists from around the world, each chapter deals with a crop: maize, rice, wheat, barley, sorghum and oat; quinoa; soybean, field pea, chickpea, peanut, common bean, lentil, lupin and faba bean; sunflower and canola; potato, cassava, sugar beet and sugarcane; and cotton. A crop-based approach to crop physiology in a G x E x M context Captures the perspectives of global experts on 22 crops
