Two on-farm commercial vegetable demonstrations were conducted in south-central Kentucky, along with three specialty melon observation plots in 2003. Grower/cooperators were located in Edmonson and Larue counties. The grower/cooperator in Edmonson County grew one acre of cantaloupes, marketed through Green River Produce Marketing Cooperative located in Horse Cave, Kentucky. In Larue County, the...
Water crisis is an important issue in arid and semi-arid regions like Iran. The situation has been getting more worse over recent years drought. Hence, there is a growing need to utilize low quality water where freshwater is scarce. In this regard, urban wastewater is a promising source but there are concerns about the environmental and health aspects of using such water. The main problem regar...
the determination of soil wetting front which caused by emitters is one of the important issues in designing trickle irrigation system. in this study, a mathematical model introduced in order to study the position of soil wetting front during irrigation by point emitters in homegenious soil in unsteady condition. the model solves governing differential equation of unsaturated flow in cylindrica...
The determination of water application parameters for creating an optimal soil moisture profile represents a complex nonlinear optimization problem which renders traditional optimization into a cumbersome procedure. For this reason, an alternative methodology is proposed which combines a numerical subsurface flow model and artificial neural networks ~ANN! for solving the problem in two, fully s...
