abstract shortage and improper distribution of rainfall in tea growing period are important growth limiting factors in tea fields in northern part of iran. if there is not any other limited factors, supplemental irrigation by sprinkler can increase tea yield. this study was carried out in order to investigate the optimum sprinkler irrigation interval on yield and water use efficiency of tea. th...
in this study, a landrace melon zarde jalali as the scion and commercial varieties of cucurbita rootstocks cv., shintozwa and ferro-rz was used as the rootstock. grafted plants upon commercial varieties of cucurbita with own-rooted and ungrafted at three irrigation levels of 60, 80 and 100% (respectively 4984.32, 6124.82 and 7239.41 m3ha-1) based on total available water depletion with drip irr...
Sugarcane has been cultivated in an extensive area in Khuzestan and irrigated by hydro-flume or siphon and furrow. In a field experiment during 2005-6 at Amir Kabir Agro-Industry, Khuzestan, the effect of every other-furrow irrigation method was studied on sugarcane in regard to irrigation water volume, water use efficiency and quality and quantity of sugarcane. The experiment was conducted in ...
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...
To investigate yield and water use efficiency (WUE) of potato with tape and furrow irrigations, an experiment was performed at Hamadan Agricultural and Natural Resources Research Center (Ekbatan station) in 2004. The experiment was arranged in a split-plot experimental design based on completely randomized block with 3 replications of irrigation water amount as the main factor (75%, 100%, 125% ...

scarcity of irrigation water and decreasing of water resources with suitable quality are the most important limiting factors in the crop production in the most of countries such as iran . therefore research for optimum usage of water and economy in consume water is important policies for growing of production and the selection of cultivars with less necessity of water can help to matter.so, an...
abstract water and nitrogen are the main limiting factors affecting agricultural production in arid and semiarid regions. therefore, improving the efficiency of these factors is very important. the method of fertilizer application is affecting water and fertilizer use efficiency. the objective of this study was to investigate the effect of furrow fertigation on fertilizer use efficiency (fue), ...
water deficit is a major factor influencing yield of canola (brassica napus l.) seed yield and oil content. a field experiment was conducted during 2010 growing season in the agriculture research station of torogh, mashhad, iran to evaluate responses of canola cultivars to limited water. experimental design was rcbd pattern with three replications. treatments were two irrigation regimes (based ...
abstract this study was conducted to determine the impacts of plastic mulch, drip irrigation method and different amount of water and their interactions on yield, water use efficiency (wue) and quality characteristic of tomato (mobile cultivar). the study was conducted in torogh agricultural research station, razavi khorasan province. the study was done during 2007-2008. experimental design was...
