In order to investigate the effect of deficit irrigation and chemical fertilizers on yield some physiological traits quinoa an experiment was conducted in 2019 as split plot based a randomized complete block design two locations (Mashhad Neishabour). Irrigation included, I0: full irrigation, I1: no at emergence stage, I2: stem elongation I3: flowering I4: seed setting stage. Fertilizer treatmen...
Due to the availability of limited water resources in the country, it is necessary to use unconventional water. On the other hand, application of minerals such as Zeolite (Zo) is necessary to simulate plant growth and reduce the harmful effects of wastewater. The present study was conducted to investigate the effect of irrigation by wastewater with Zo on cotton (Gossypium herbaceum) based on a ...
the objective of this study was to evaluate the effect of different levels of irrigation and nitrogen fertilizer on nitrate movement, yield, and water use efficiency (wp) of corn in no-till planting method. the research was conducted in two years as a randomized complete block design arranged in a split block treatment design with three replicates in the safiabad agricultural research center. i...
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...
to investigate the effect of deficit irrigation on quantitative and qualitative yield of soybean cultivars, an experiment was conducted as split plots based on randomized complete block design with three replications at agricultural research farm, university of guilan, during 2009. main factors were included four irrigation levels based on potential moisture 30-35 (i1), 50-55 (i2), 70-75 (i3) c...
in order to improve irrigation water productivity (wp) at rice production, a field experiment was conducted at shahid fozveh research station (esfahan region) during 2001-2003. experiment was arranged in a split plot design (rcbd) with three replications. the treatments were: three levels of irrigation managements including i1: permanent flooding under 3.5cm water during growth period, i2:perma...
Subsurface drip irrigation systems, compared to other irrigation systems (basin and furrow), enhance the delivery of water and nutrients directly into the root zone. The purposes of this study were to determine wetting front advancement in a subsurface drip irrigation and to compare the results with the HYDRUS 2D model simulation. In this study, the irrigation using T-Tape was carried out on a ...
In order to study the relationships among traits and grouping genotypes of wheat, 11 promising lines of winter wheat along with Orum, Zareh, Mihan, Zarrin and peshgam cultivars were evaluated under two levels of irrigation (complete irrigation and cutting irrigation from flowering to maturity) at Agricultural Research Station of Miandoab during 2013-2014 and 2014-2015 growing seasons. The exp...
Using water and fertilizer management at the farm level can be increased water use efficiency and reduce the volume of drainage water, fertilizer losses, and other pollutants in farmland with deep underground drains such as Khuzestan agro-industrial Companies. In the present study, a comprehensive simulation model for the water cycle and the nitrogen dynamics modeling was used for water and fer...
in order to investigate effect of deficit irrigation on phenological stages and yield of soybean cultivars, an experiment was conducted as split plots based on randomized complete block design with three replications at agricultural research farm, university of guilan in 2009. main factor was included four irrigation levels based on potential moisture 30-35 (i1), 50-55 (i2), 70-75 (i3) centibar...
