Available in PDF, EPUB and Kindle. Book excerpt: Agrometeorology is a comparatively young science. The beginnings of agrometeorological work came in the 20's of this century, when agrometeorology was a working branch of climatology. In the years following 1950 it then developed widely to an independent science. In this process, agrome teorology has not only gained a vast knowledge of the influence of meteorological conditions on plants and livestock in agriculture and damage prevention, but additionally evolved new advisory methods which are of great practical use in agriculture. Up to the present time there has been practically no specific training for an agrometeorologist. Agrometeoro logists are drawn, according to their training, from the ranks of general meteorology or from agriculture and its related biological disciplines. They must, therefore, them selves gather the knowledge for their agrometeorological work and combine for themselves the complex of agrome teorology from biological and meteorological information. This is usuaIIy far from easy, as the relevant literature is scattered among the most widely differing journals, partly in little-known foreign languages, and is thus very difficult of access. Comprehensive writings are to be found only in very few partial fields of agrometeorology. The subject of training problems has thus been treated as of utmost importance at the meetings ofthe Commission for Agrometeorology (CAgM) of the World Meteorological Organization (WMO), especially as agrometeorology has won such great significance and useful ness not only in the so-called underdeveloped countries in advancing a more productive agriculture, but also in coun tries whose agricultural standard is already high.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Water Requirement of Plants, Vol. 1: Investigations in the Great Plains in 1910 and 1911 The term water requirement is used in this paper to indicate the ratio of the weight of water absorbed by a plant during its growth to the weight of dry matter produced. The water requirement of a grain - producing field crop may be expressed either in terms of the total dry matter produced or on the basis of the grain alone and is found by dividing the total weight of the water absorbed during the Whole period of growth by the total dry weight or by the weight of the grain, respectively. The results of earlier investigations have shown that some of the amp plants differ materially as regards their water requirement. The subject thus becomes one of considerable economic importance in connection With the agriculture of semiarid regions, since the crop or variety Which is most economical in the use of water, other things being equal, is evidently the one best adapted to regions having a limited water supply.

Available in PDF, EPUB and Kindle. Book excerpt: Principles of Soil and Plant Water Relations, 2e describes the principles of water relations within soils, followed by the uptake of water and its subsequent movement throughout and from the plant body. This is presented as a progressive series of physical and biological interrelations, even though each topic is treated in detail on its own. The book also describes equipment used to measure water in the soil-plant-atmosphere system. At the end of each chapter is a biography of a scientist whose principles are discussed in the chapter. In addition to new information on the concept of celestial time, this new edition also includes new chapters on methods to determine sap flow in plants dual-probe heat-pulse technique to monitor water in the root zone. Provides the necessary understanding to address advancing problems in water availability for meeting ecological requirements at local, regional and global scales Covers plant anatomy: an essential component to understanding soil and plant water relations

Available in PDF, EPUB and Kindle. Book excerpt: Water Deficits and Plant Growth, Volume II: Plant Water Consumption and Response focuses on internal water deficits in plants, the measurement for such deficits, and the identification of physiological and growth responses of herbaceous and woody plants to water deficiency. Partitioned into six chapters, the book discusses the rate of water consumption of agricultural plants. Concerns in this part include evapotranspiration, characteristics of plants, and climate. The discussions move on to the study of water consumption in forests. The methods used in the research, the theoretical considerations, and a review of the results are also discussed. The next part focuses on the relationship of water deficits and physiological processes. This part also introduces the discussions on the effect of water deficiency on the growth of herbaceous plants and trees, including the emergence of diseases related to water deficiency. The book is a valuable source of data for readers who are interested in pursuing studies on the effect of water deficiency on the growth of plants.

Available in PDF, EPUB and Kindle. Book excerpt: Water requirement was defined by Briggs and Shantz in 1911 as the ratio of the weight of water absorbed by a plant during its growth to the weight of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter produced. Ballard (1933) and Williams (1935) defined water requirement as the ratio of the amount of water transpired to the amount of dry matter formed during the whole or any part of the life cycle of the plant. Miller (1938) and Kramer (1959) postulated that the water requirement is the ratio of water used to the dry matter produced, and therefore could more accurately be termed transpiration ratio because it is largely controlled by transpiration. Regardless of specific definition, the dry matter considered in such ratios is generally the amount harvested, including the entire plant except the roots. The amount of water measured is the amount lost during growth since the amount of water retained within the plant is insignificant when compared with either total water intake or the amount transpired. The water requirement thus constitutes a useful way to characterize the plant and soil-water conditions and plant growth. The availability of soil water to a plant is one of the factors that vitally affects its water requirements. In turn, the availability of soil water is affected by soil moisture tension and the salt content of the soil. Thus it seems likely that a significant relationship may exist between a plant's water requirement and its degree of salt tolerance. The relation between water requirement and salt tolerance could not be established based on the information found in the literature at this time. the study reported here was undertaken in an attempt to determine the effect of salt on the water requirement of plant species known to have different degrees of salt tolerance.
