This book was released on 2019 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dry edible bean (Phaseolus vulgaris L.) is one of the most important pulse crops in the world. Unfortunately, limited information is available on its growth, yield, soil moisture dynamics, water use, crop coefficients, and yield response under furrow and sprinkler irrigation system. Field experiments were conducted at Powell Research and Extension Center, Powell, Wyoming, USA. The study was conducted to assess dry bean water use, growth and yield dynamics, and crop water productivity. Five irrigation gradients were evaluated FIT (full irrigation treatment), 125% FIT, 75% FIT, 50% FIT, and 25% FIT under furrow irrigation, and linear-move sprinkler irrigation system. Crop evapotranspiration (ETc) ranged from 186 – 438 mm and 190 – 409 mm in the 2017 and 2018 growing season, respectively, under sprinkler irrigation system. Under furrow irrigation system, ETc ranged from 332 – 366 mm and 332 – 378 mm in 2017 and 2018 growing season, respectively. A linear relationship was observed between the growth traits and yield components; however, the relationships were weaker for furrow irrigation. Also, a linear relationship existed between grain yield and ETc, whereas, a quadratic relation was observed between grain yield and irrigation and total water use. The crop water productivity was higher under sprinkler irrigation. Overall, furrow irrigation promotes better root development, however, the tradeoff in water use efficiency and also, the risk of waterlogging, and flooding stress associated with furrow irrigation are considerable. The crop coefficient (Kco) value on average for the FIT for initial-, mid-, and late-season were 0.61, 1.16, and 0.37, respectively, under sprinkler irrigation. The crop coefficient (Kco) value on average for the FIT for initial-, mid-, and late-season were 0.74, 1.07, and 0.43, respectively, under furrow irrigation.

Available in PDF, EPUB and Kindle. Book excerpt: Make the best use of available water for your crops! Water Use in Crop Production explores innovative methods that determine how much water certain crops need, in certain climates, in order to ensure adequate plant growth and help eliminate water waste. Through this informative book, agronomists, growers, researchers, and graduate students will find methods and techniques for effective water management that will save money and conserve water. Water Use in Crop Production will enable you enhance crop quality and quantity and save one of the earth's most important resource. Comprehensive and thorough, this essential book combines two vital needs, food and water, and examines what must be done in order to keep up with the ever-growing human population. Explaining conservation techniques used in Argentina, Australia, Israel, Morocco, New Zealand, the Philippines, Spain, and the United States, Water Use in Crop Production will help you achieve this goal as it discusses water management measures including: avoiding excessive deep percolation reducing runoff lessening water evaporation through methods such as reducing the capillary water flow to the surface of the soil determining the rates at which water is demanded and can be supplied in a specific area to create a plan for limiting water loss studying the root structure of plants to calculate how much water they need using deficit irrigation to help plants save water for future use evaluating citrus water use through the Penman-Monteith model Containing charts, tables, and examples of the concepts it discusses, this book is the culmination of the latest studies on water storage. Water Use in Crop Production provides you with reliable strategies and methods that will help you lessen water expenditures and improve the vitality of crops anywhere in the world.

Available in PDF, EPUB and Kindle. Book excerpt: This report aims to synthesize the results of a crop water use study conducted by country teams of the GEF/World Bank project, Regional Climate, Water, and Agriculture: Impacts on and Adaptation of Agro-ecological Systems in Africa. It also presents the results of the second phase of the study based on climate change scenarios, conducted by the South Africa country team. The actual evapotranspiration of five commonly grown crops-maize, millet, sorghum, groundnuts, and beans-in two selected districts were analyzed by six country teams. In addition, two country teams also analyzed other crops grown in the districts. The regional analysis shows that the actual yield of the different crops-specifically of maize and groundnuts-improves with an increase in actual evapotranspiration, although the gap remains wide between actual and potential yield and actual and maximum evapotranspiration, especially for the rainfed crops. This highlights the importance of improved water management if agriculture is to play an important role as a source of food security and better livelihoods. The report highlights the vulnerability of maize to water stress and the increased risks to the viability of rainfed farming systems based on this crop. The results of the second phase of analysis show that a 2°C increase in the temperature and a doubling of carbon dioxide concentration in the atmosphere will shorten the growing period of maize, which will result in decreased crop water requirement and use. The authors recommend extending this type of analysis to other crops as well as to other countries to develop a clearer picture of the changing pattern in crop water use of the major crops grown in the project countries.

Download or read book Guidance on realizing real water savings with crop water productivity interventions written by Van Opstal, J., Droogers, P., Kaune, A., Steduto, P., Perry, C. and published by Food & Agriculture Org.. This book was released on 2021-03-18 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical document contains clear and practical guidelines on how to implement real water savings in agriculture through interventions for enhancing crop water productivity. A distinction is made between real water savings and “apparent” water savings. Apparent water savings record reductions in water withdrawals but do not account for changes in water consumption. Real water savings record reductions in water consumption and non-recoverable return flows (runoff or percolation). This guidance document emphasizes the paradox of water savings at field and basin scales, which usually do not translate into increased water availability for other users, as is commonly believed.
