It mainly uses the improved BP neural network based on the GA algorithm to develop the yield-irrigation water model for predicting the corn yield for different irrigation systems under subsurface drip irrigation.
The lack of drainage was glossed over in the rush to develop the land with irrigation.
One of the constraints in developing optimum irrigation facilities is the lack of engineers and technicians as well as of farmers trained in modern irrigation techniques.
As leaders of a large number of villagers, these jitō laboured to develop the rice fields and irrigation works in the areas under their jurisdiction, and they and other influential landlords constructed spacious homes for themselves in the villages and hamlets where they lived.
Located in southern Mesopotamia, present-day Iraq, Sumerians developed the wheel, writing, sophisticated irrigation and agricultural techniques, sailboats, calendars and cities, as far back as 3500 B.C.
The DSS-EVIW (Decision Support System for Economic Value of Irrigation Water) was implemented to compute and develop the economic value of irrigation water maps.
Nevertheless, if Ethiopia is to exploit its river resources, it will have to develop the necessary civil and irrigation works, which will require a decade or more of effort and investment.
Most fruit crops do not come into contact with irrigation water in developing countries, since the irrigation water is spread through furrows under the trees, well below the fruits up in the tree canopy.
Greenhouse-grown hot pepper was used to investigate the effect of Time-Space deficit irrigation (TSDI), a newly developing irrigation technique based on regulated deficit irrigation (RDI) and partial rootzone drying (PRD), by measuring plant growth, yield and irrigation water use efficiency.
The country is actively developing its irrigation potential that ultimately will irrigate more than 2.5 million acres (1 million hectares).
