Effect of Deficit Irrigation on Yield and Water Use Efficiency of Maize at Selekleka District, Ethiopia [PDF]

, 2020
Irrigation water availability is diminishing in many areas of the Ethiopian regions, which require many irrigators to consider deficit-irrigation strategy. This study investigated the response of maize (Zea mays L.) to moisture deficit under conventional,

EFFECTIVE MANAGEMENT OF ON-FARM IRRIGATION FOR SOME MAJOR CROPS IN EGYPT USING CROPWAT MODEL [PDF]

Misr Journal of Agricultural Engineering, 2019
Field experiments were carried out (2013/2014 and 2014/2015 for wheat; 2014 and 2015 for maize) at the two sites of Giza area (Giza governorate, represented to Middle Egypt) and Shandaweel area (Sohag governorate, represented to Upper Egypt). The present study aims to improve water management in on-farm using CropWat model.

Spatial Simulation and Optimization of Cropping Structure Under Climate and Land Use Change Conditions Considering Synergistic Economic Benefits and Carbon Reduction in Crop Growth Processes

Earth's Future, Volume 12, Issue 10, October 2024.
Abstract The climate and land use changes caused by the natural environment and socioeconomic development have potential impacts on the green and sustainable development of agriculture. To accommodate agricultural production under multiple scenarios of future climate and land‐use change, this study proposes a “simulation–optimization” modeling approach

Sustainable sweetpotato production in the United States: Current status, challenges, and opportunities

Agronomy Journal, Volume 116, Issue 2, Page 630-660, March/April 2024.
Abstract Sweetpotato (Ipomoea batatas L.) is an important staple crop cultivated in over 100 countries, and the storage roots and vines provide food for humans and livestock. Sweetpotato consumption and demand for its value‐added products have increased significantly in the last two decades and have led to new cultivar development, expansion in acreage,

Response of Carrot (Daucus carota L.) to Supplementary Irrigation under Rain‐Fed Agriculture at Jimma and Gera, Jimma Zone, South West Ethiopia

Advances in Agriculture, Volume 2024, Issue 1, 2024.
Evaluating supplementary irrigation under rain‐fed agriculture could help to determine the amount of water depth for water management and increasing productivity. Thus, this study was conducted at the Jimma and Gera to determine the effect of supplementary irrigation (SI) on carrot production. Eight treatments with three replications on a field plot of

SIMULATION OF WINTER WHEAT WATER BALANCE WITH CROPWAT AND ISAREG MODELS

, 2013
This paper presents the results of water balance simulations on winter wheat production in the area around Bijelo Polje. Winter wheat production over three years and on two soil types has been simulated with the CROPWAT and ISAREG models. The simulated results have proved variations between the two models and the measured yield. Crop evapotranspiration
