* Department of Soil Science, Punjab Agricultural University, Ludhiana 141 004 Abstract: Different irrigation methods and regimes affect maize (Zea Mays L.) growth differently. The field experiment was conducted to study the interactive effect of three irrigation methods and three irrigation regimes on maize growth under sandy loam soil at the Research Farm of Department of Soil Science, Punjab...

A survey based study was conducted in three districts of Bangladesh to understand the mode of input pricing, problems of timely availability of inputs and the existing input subsidy scenario of Boro rice. Applying the conventional descriptive statistics, the study revealed that there are three major modes of payment for irrigation charges prevailing all over the study areas and it varied from l...

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.

Dwindling water resources combined with meeting the demands for food security require maximizing water use efficiency (WUE) both in rainfed and irrigated agriculture. In this regard, deficit irrigation (DI), defined as the administration of water below full crop-water requirements (evapotranspiration), is a valuable practice to contain irrigation water use. In this study, the mechanism of paclo...

Hay and silage crops are integral parts of beef production in the Great Plains. In the southern Great Plains, a growing dairy industry is adding demand for silage and hay. Corn silage has long served the region well, producing consistent high quality silage. However, many areas of the southern Great Plains no longer have the irrigation capacity to successfully produce corn silage. Forage sorghu...

The decline in groundwater supply the Texas High Plains is forcing some growers to convert center-pivot irrigated cropland dryland production. Transitioning toward reduced water input can lead declines soil health. We assessed short-term changes health indicators two transition scenarios: (a) from high irrigation method low (center pivot subsurface drip) and (b) dryland), comparison continuous ...

One hundred and seventy-four consecutive patients with symptoms of derangement of the knee were examined with an arthroscope under local anaesthesia using a continuous pressure-irrigation system. A 0.2 per cent prilocaine-saline solution was used as irrigation fluid. In the first 19 patients the serum level of prilocaine was monitored for six hours after the start of irrigation. Eighteen of the...

as irrigation system installation is expensive and time consuming, it would be better to have an estimate of the water content provided by the system in the active root zone before designing an irrigation system. in this study, hydrus-2d performance was assessed under a tape irrigating in-situ with a heavy textured and relatively heterogeneous soil in rasht region. three different flows i.e. 2....

Introduction. This experimental study is to compare radiographs based on the penetration depth of the irrigant following three final irrigation techniques. Material and Method. A sample of sixty teeth with single roots were prepared with stainless steel K files followed by mechanized Ni-Ti files iRace® under irrigation with 2.5% sodium hypochlorite. Radiopaque solution was utilized to measure t...
