Paperback. Condizione: New. Print on Demand. This book chronicles the water consumption of representative plant species commonly used in agricultural practices, focusing on crops grown at the same location under identical environmental conditions. The author, a biophysicist and plant physiologist, conducted a series of experiments to determine the water requirement of each plant, defined as the ratio of water absorbed during its growth to the weight of the dry matter produced, excluding the roots. The measurements were conducted in large galvanized pots covered with tight-fitting lids to minimize water loss and exclude rainfall. The results of these experiments provide valuable insights into the relative water efficiency of different plant species, which can inform crop selection and irrigation practices in regions with limited water resources. Understanding the water requirements of crops is crucial for sustainable agriculture, particularly in the face of increasing water scarcity and climate change.
