Deficit Irrigation of Cotton in Tennessee
5th National Decennial Irrigation Conference Proceedings, 5-8 December 2010, Phoenix Convention Center, Phoenix, Arizona USA, 2010The goal of this research was to determine the level of deficit irrigation that provided the highest economic return for cotton. Drip tape was used to create nine deficit irrigation treatments compared to a rainfed control in a RCB design. Irrigation was initiated at square, bloom, and post-bloom by opening manual valves on the drip lines while ...

Evapotranspiration of Deficit Irrigated Sorghum
World Environmental and Water Resources Congress 2007, 2007Deficit irrigation commonly is used in regions with reduced or limit ed irrigation capacity to increase water use efficiency (WUE). This research measured sorghum ( Sorghum bicolor L. Moench ) water use (ET) and yield so WUE could be determined. Two precision weighing lysimeters were used to accurately measure sorghum ET fr om a fully irrigated field ...

Advances in Deficit Irrigation Management
5th National Decennial Irrigation Conference Proceedings, 5-8 December 2010, Phoenix Convention Center, Phoenix, Arizona USA, 2010Scarcity of irrigation water supplies is leading to the need to consider deficit irrigation which is the intentional under-irrigation of crops resulting in evapotranspiration and yield reduction. We present analytical tools that can be used to assist irrigators and water managers in assessing the water balance and economic consequences of various ...

Macromanagement of deficit-irrigated peanut with sprinkler irrigation
Agricultural Water Management, 2009Precision irrigation management and scheduling, as well as developing site- and cultivar-specific crop coefficient (Kc), and yield response factor to water deficit (ky) are very important parameters for efficient use of limited water resources. This study investigated the effect of deficit irrigation, applied at different growth stages of peanut with ...

Effects of Deficit Irrigation and Irrigation Frequency on Wheat Yields
Journal of Irrigation and Drainage Engineering, 1989The relationship between wheat yields and irrigation frequency was studied in a set of field experiments. Experimental plots were irrigated at intervals that ranged from two days to four weeks.

EFFECT OF DEFICIT IRRIGATION ON THE PRODUCTIVITY AND CHARACTERISTICS OF TOMATO
Misr Journal of Agricultural Engineering, 2013In order to assess the effect of water irrigation deficit during season on yield and mechanical damage of processing tomato, an open field experiment was carried out in two seasons 2010/2011 – 2011/2012. Four irrigation treatments were studied: (ET1: 1 time potential crop evapotranspiration (ETc), ET2: 0.9 ETc, ET3: 0.8 ETc and 0.7 ETc, ET4). The study

Irrigation Water Use Efficiency Based on the Deficit Irrigation Theories
Advanced Materials Research, 2013Irrigation water use efficiency is an important index to evaluate agricultural water use efficiency of irrigation districts, and is a basic parameter of hydraulic engineering construction and water management. However, there are many problems in practical applications of the traditional irrigation water use efficiency which is based on sufficient ...
