Sustaining Chili Pepper Production in Afghanistan through Better Irrigation Practices and Management
Water management and utilization is an ongoing problem in developing countries with semi-arid to arid climates such as Afghanistan. The lack of effective irrigation systems are oftentimes the most limiting factor for maximizing agricultural productivity in these countries. In Afghanistan, the most widely used irrigation methods are basin/border for cereal crops and furrow for vegetables and gra...
Soil moisture is one of the main input parameters in many models for monitoring and predicting crop yield. The ability of mathematical models has allowed correct application of brackish water and selection of management options. The purpose of this research was to evaluate the performance of HYDRUS-2D for simulating soil volumetric water content in a heterogeneous heavy soil under field conditi...
in order to study the effects of different irrigation system and different amounts of nitrogen fertilizer on yield and quality of sugar beet, an experiment was conducted at ekbatan research station, hamedan during 2005-2006 as split plot based on randomized complete block design with three replications. the main plots were irrigation systems (furrow, sprinkler and drip irrigation) and subplots...
In order to compare the effect of drip and furrow irrigation methods with different quantities of water (50%, 75%, and 100% of the amount of water evaporated from class A pan evaporation during irrigation intervals) on yield and quality of tomato, an experiment was conducted on a silty loam soil in Mashhad Agricultural Research Station. The experimental design was a factorial trial with complet...
Two field experiments were conducted in Aly Mubark experimental Farm in sandy soil at El-Bustan Sandy soil irrigated by drip irrigation, during 2003 and 2004 seasons. The experiments aimed to study the effect of three irrigation treatments with three different kinds of fertilizers and its concentration on sage growth, yield, essential oil yield and components, macro-nutrients content in dry her...

This report investigates the costs and benefits associated with the conversion from semi-enclosed seep irrigation to either automated seep or automated sub-drip irrigation for potato production in Northeast Florida. These costs and benefits are estimated at the level of the individual grower and for the public at large. The analytical tools in the report include financial budgeting and regressi...
A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.
One of the biggest obstacles to the widespread adoption of subsurface drip irrigation (SDI) on the High Plains of Texas is the high cost of initial installation. In some cases, SDI costs can be reduced if systems are designed using lower irrigation uniformity standards. The question becomes “what is the cost in terms of cotton lint yield of lowering the uniformity standards for SDI design?” A S...
Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...
