...I and DI, 100 and 50% of evapotranspiration (ET) was replaced by irrigating the entire pot surface every 4-5 days. For PRD, root system was split into two equal halves and during each irrigation event, only one-half of the root system was irrigated with the same amount of water as applied to DI, and subsequently, irrigation was switched to the second half. PRD irrigation significantly improved WUE (both photosynthetic and intrinsic) and instantaneous carboxyla...

IMPACTS OF CLIMATE CHANGE ON CROP WATER REQUIREMENT UNDER MULTI - REPRESENTATIVE CONCENTRATION PATHWAYS DURING MID-CENTURY: A CASE STUDY OF D. I. KHAN
...as conducted to estimate evapotranspiration (ETo) and crop
water requirements (CWR) of wheat and maize crops of the study area during mid (2040-2059) century under emission
scenarios based on Representative Concentration Pathways (RCPs). The methodology employed here involves
the comparison of temperature and precipitation data projected by different GCM with the observed data. The delta
change and ratio method was used to obtain th...

YIELD RESPONSE AND WATER USE EFFICIENCY OF SUGAR BEET IN SEMI-ARID ENVIRONMENT UNDER DIFFERENT DEFICIT IRRIGATION REGIMES
...d between root yield and evapotranspiration was linear. It can be concluded from the study that, for better sugar beet yield, full irrigation treatment should be used for semi arid conditions with no water shortage. However, in water limited situation, sugar beet may be irrigated at 80% offull irrigation. This might decrease the sugar beet root and sugar yields by 13.7% and 9.10%, however it may save 20% irrigation water that can be used to bring more are...

...er productivity based on evapotranspiration (WPET). The field results indicated, comparable yield for the NB treatment but increased (2.4%) the water productivity based on irrigation input (WPi), saved (3%) irrigation water and reduced (3%) deep drainage losses than the FB treatment. However, the WB treatment reduced (7.5%) crop yield, but increased the WPi (242%) and saved (73%) irrigation water. Thus, optimally managed furrow and drip irrigated raised beds c...

...> Model to calculate evapotranspiration of rice harvests in the province of An Giang, Vietnam, and evaluating the entire water demand for the production of rice in the year 2020. The results showed that the value ET0 for rice in An Giang province ranged from 3.2 to 3.91 mm.d-1, and averaged 3.73 ± 0.34mm.d-1 (equivalent to 1,323 mm.yr-1). Crop evapotranspiration (ETc) and its actual estimation was 1,588 mm.yr-1. I...
