water stress decrease water content and water potential between soil and root. therefore, water potential of plant declines and plant faces with water stress. water stress in different stages of growth can be useful in different aspects. water stress can be practiced from two point of view, increasing water use efficiency (wue) and improving cultural practices. no irrigation in insensitive sta...
In order to determine the effects of number of irrigations on stages of development, yield, and yield components of cumin, an experiment was conducted in 1993 - 94 growing season with a randomized complete block design and four replications. The location of the experiment was Isfahan University of Technology Research Station in Shervedan Field. The irrigation treatments were: I1- Irrigation aft...
In tea plantation regions of northern part of the country, application of supplemental irrigation during dry periods (lacking rainfalls) in conjuction with proper nitrogen fertilizer application can significantly improve tea yield per unit of plantation area. In order to quantify the effectiveness of proper irrigation and nitrogen management on tea, the response of tea to various levels of irri...

Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...
proper use of water resources in arid and semi-arid regions is important and vital. this study was conducted to evaluate the effect of irrigation scheduling by various methods on crop yield and water use efficiency (wue) by wheat, and determining suitable irrigation-scheduling method for irrigation of wheat in saeedabad, tabriz. a field experiment was conducted with 10 irrigation treatments (i1...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
In order to study the effects of foliar application of potassium (K) and boron (B) and dificit irrigation treatments on quantitative and qualitative traits of sugar beet (Beta vulgaris L.), a split plot experiment was conducted based on randomized complete block design with three replications in the Research Field of Shahrekord University, Shahrekord, Iran, in 2019. The main plots were allocate...
to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...
