Drip irrigation systems offer the potential for efficient irrigation of high value crops and have proven feasible from engineering and agronomic standpoints in the northern Great Plains. However, little information is available in this region regarding the optimum design and economics of these systems. The objective of this study was to develop a computerized model for design and economic optim...

given the scarcity of water resources using modern methods of irrigation in agriculture will be inevitable. today, process improvement, development and use of drip irrigation practices as one of the most advanced methods of irrigation in agriculture is increasing. so this study was conducted to determine the impacts of irrigation interval and drip irrigation method and their interactions on yie...

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...

The Australian Government is meeting the challenge of water scarcity and climate change through significant on-farm infrastructure investment to increase water use efficiency and productivity, and secure longer term water supplies. However, it is likely that on-farm infrastructure investment will alter energy consumption and therefore generate considerable greenhouse gas (GHG) emissions, sugges...

A field experiment was carried out to study the changes of soil bacteria, fungi and actinomycetes in saline-sodic soils for different numbers of cultivated years under drip irrigation. The drip irrigation had substantial effects on levels of bacteria, fungi and actinomycetes. With increased number of cultivated years under drip irrigation, the soil biological properties were greatly improved. A...

Adoption of drip irrigation in Kerala State of India is very low and potential exists toincrease its adoption in the State. A field survey was conducted in two districts to determine themajor factors influencing farmers’ adoption of drip irrigation and to draw conclusions that willhelp in developing policy and institutional interventions to encourage the adoption. The resultsindicated that adop...

Halosulfuron is a proposed alternative to methyl bromide for managing nutsedges (Cyperus spp.) in several vegetable crops, including cucurbits. Field studies were conducted to evaluate the crop sensitivity to halosulfuron in a spring squash (Cucurbita pepo L.)—fall cucumber (Cucumis sativus L.) rotation from 2000 to 2002. Treatments included application of halosulfuron to the soil surface after...

abstract this study was conducted to determine the impacts of different drip irrigation method and amount of water on yield and water use efficiency of tomato in varamin agricultural research center, iran. the study was done during two years. experimental design was randomized complete blocks design (rcbd) in split plot with three replications. three different drip irrigation method; surface dr...
