damage caused by water shortages leads to physiological and biochemical changes in metabolism of plants and make them predispose to attack by pests and diseases and reduce the quality of the crops. in order to evaluate the effect of supplemental irrigation on safflower fly (a. helianthi) population of safflower cultivars, an experiment conducted as a split plot based on randomized complete bloc...

water scarcity is a major factor for limiting crop growth and development in arid and semi-arid regions. in order to study the effects of varying timing and severity of water deficit on mung bean phenological traits, a field experiment was carried out during 2009 growing season at agricultural research institute of zabol university. the experiment was laid out in split plot by using a randomize...

to study the effect of humic acid and drought stress on some physiological characteristics of roselle (hibiscus sabdariffa) an experiment was conducted in the research field of agricultural education centre of jiroft in 2013. field experiment was carried out as split plot design with three replications. water deficit stress as main factor with three levels (a1 = irrigation after 50, a2 = 100 an...

There are some plants can replaced grass among cover plants. Cover plants are obvious solution of problem in these places that the most important plant is Frankinia and Lisimakia etc. The aim of this study is to use organic wastes, biological fertilizers and moisture super absorbents in the growth media of Frankinia to increase water holding capacity, delay in permane...

to investigate the effects of supplementary irrigation and application of different compost levels on morphological traits, yield and yield components of two chickpea cultivars under dry land conditions, a field experiment was conducted at the research field in khoramabad, iran in 2009-2010. the experiment was split split plot based on randomized complete block design with four levels of irriga...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...
