Successful potato irrigation scheduling

Creator:: Shock, Clinton C., Flock, Rebecca, Eldredge, Eric, Pereira, Andre, Jensen, Lynn, and Oregon State University. Extension Service
Abstract:: In the late 1980s, the U.S. Pacific Northwest potato industry faced a crisis. Potato tuber quality was inadequate to meet the needs of potato processing companies due to a condition called “sugar ends” or “dark ends” in fried tuber slices. This defect was common in tubers grown on stressed Russet...

Irrigation scheduling

Creator:: Trimmer, Walter L., Hansen, Hugh J., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension Service, and United States. Department of Agriculture
Abstract:: The main purpose for irrigating is to supply needed water for crops. Plant growth is dependent on photosynthesis. While the plant exchanges gases with the air for photosynthesis, some water evaporates. Water is taken up from the soil by plant roots to replace this water. The water leaving the plant...

Optimization of seasonal irrigation scheduling by genetic algorithms

Creator:: Canpolat, Necati
Abstract:: In this work, we first introduce a novel approach to the long term irrigation scheduling using Genetic Algorithms (GAs). We explore the effectiveness of GAs in the context of optimizing nonlinear crop models and describe application requirements and implementation of the technique. GAs were found to converge quickly to near-optimal...

Strategies for reducing irrigation water use

Creator:: Jensen, Lynn, Shock, Clinton C., and Oregon State University. Extension Service
Abstract:: When water is plentiful, growers usually schedule irrigation practices around other farming activities. For example, most growers change furrow irrigation sets at 12- or 24-hour intervals because this timing is convenient and uses labor efficiently. When water is in short supply, you need to rethink some practices to obtain maximum...

Using infrared canopy temperature and leaf water potential for irrigation scheduling in peppermint (Mentha piperita L.)

Creator:: Gallardo, Ivan T.
Abstract:: Several methods of infering plant water stress for irrigation scheduling are based upon measurements of the environment in which the plants grow. These measurements include parameters such as soil water content, air temperature, pan evaporation and incident radiation. It is hypothesized that improved estimates of plant water deficit can be...

Optimal irrigation management : a framework, model, and application for optimizing irrigation when supplies are limited

Creator:: Hillyer, Charles C.
Abstract:: Many regions in North America are experiencing water shortages, and these conditions are expected to worsen. The next generation of irrigation scheduling applications must therefore be capable of providing operational advice in support of deficit irrigation strategies. However, the theoretical, technical, and practical challenges associated with deficit irrigation scheduling are...

Addressing Data Resolution in Precision Agriculture

Creator:: Kelley, Jason
Abstract:: Irrigated agriculture constitutes the greatest consumptive water use globally, so that irrigation efficiency measures are an important part of global efforts to best utilize this limited resource. However, greater irrigation efficiency must be achieved while simultaneously maintaining or increasing crop yields and farming profitability. Incremental water use decisions are made...

Improving soil water determination in spatially variable field using fiber optic technology and Bayesian decision theory

Creator:: Sayde, Chadi
Abstract:: Achieving and maintaining sustainability in irrigated agriculture production in the era of rapidly increasing stress on our natural resources require, among other essential actions, optimum control and management of the applied water. Thus, a significant upgrade of the currently available soil water monitoring technologies is needed. The primary goal of...

Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...
