In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
To study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and oil percentage of Goldasht spring safflower cultivar, an experiment was carried out in 2012 in the Agricultural Research Farm Station of Islamic Azad University, Roudehen branch as split plot in a completely randomized blocks design with three replications. In ...

In order to evaluation effect of different level of humic acid affected drought stress on seed yield, its components and morphological traits of corn a research farm was conducted according split plot experiment based randomized complete blocks design at three replication during 2015 year. Main factor included four irrigation regimes (90mm, 110 mm, 130 mm and 150mm evaporation from pan class A)...
BACKGROUND: Nutrients play a very important role in chemical, biochemical, physiological, metabolic, geochemical, biogeochemical, and enzymatic processes. Innovations for saving water in irrigated agriculture and thereby improving water use efficiency are of paramount importance in water-scarce regions. Conventional deficit irrigation is one approach that can reduce water use w...
The study was conducted in the northern Texas Rolling Plains in 1999 to define the relationship between number of cotton aphids, Aphis gossypii Glover, and resulting contamination of cotton lint by honeydew. Whole-plot treatments were three furrow irrigation management treatments: cotton grown without supplemental irrigation (dryland), irrigated cotton with last irrigation in mid August, and ir...
BACKGROUND: Polyacrylamide is the main synthetic polymer used, and it absorbs water through the formation of hydrogen bonds. Super Absorbent Polymer (SAP) can absorb water up to 200-400 times its weight and increase its size by up to 100 times. OBJECTIVES: Evaluate effect of different irrigation regime and super absorbent polymer on agrop...
