sustainable agriculture for producing food is not possible without optimal use of water resources. because of the limitation of water resources, deficit irrigation would be essential to increase water productivity. in order to evaluate the effects of deficit irrigation on quality and quantity of sugar beet, an experiment was carried out in a farm in miandoab agricultural research station for 2 ...

The present study aims to assess the effect of Thiobacillus and sulfur on morphological and biochemical properties of medicinal pumpkinproperties under deficit irrigation based on a split-plot design. For this purpose, water stress was applied as a main factor in three levels (control, no irrigation in flowering stage, no irrigation in fruiting), and Thiobacillus and sulfur fertilizers as sub-p...

this research was conducted at torogh agricultural research station in khorasan-e razavi province to determine the impact of irrigation cutoff at different growth stages and percentage of water use on the yield and water use efficiency (wue) of wheat cultivars using sprinkler irrigation. the study was done from 2006-2008. the experimental design was a randomized complete block design with a str...

ABSTRACT- Despite the benefits of herbicides, their persistence in soil can harm other plants in next rotations and contaminate ground water. The main purpose of this research is to simulate 2,4-dichlorophenoxyaceticacid(2,4-D) movement in silty clay loam soil using HYDRUS-1D model in a corn root zone. The maximum contaminant level goal, MCLG, of 2,4-D in water resources is 10 ppb. The 3.5 kg a...

drought is common across the south of iran, especially in darab district. accordingly, studying the economic aspects of deficit irrigation technique – that is one of the basic strategies in water saving for reducing water use of cotton as one of the main agricultural products in darab district is essential. in order to investigate the deficit irrigation technique and to determine its economic t...
