Abstract: To investigate the effect of nutrition management along with zeolite application on the fertilizer use efficiency and irrigation water productivity of two cultivars of maize under deficit irrigation conditions, a field experiment was carried out. The experiment was conducted at Soil and Water Research Institute, Karaj, Iran, in 2015 and 2016, in the form of a   factorial split plot...

The main objective of this study was evaluation of integrated management and mixing saline/fresh water on soil salinity distribution. For this purpose, a field was selected and 32 plots were made in it with a 6 m×2.5 m size. A split plot experiment was employed with two sunflower varieties (Alstar and Hisan33), four irrigation schemes (CIS) and four replications. Irrigation schemes being ...

Increasing crop production per unit volume of water consumption requires recognizing the most dependent variable in drip irrigation to the volume of water consumption and also identifying the most important variables independent of water productivity in surface and subsurface drip irrigation for optimal use of available water resources. The present research was carried out in Behbahan Agricultu...

This experiment was carried out to investigate the effect of biopolymer coated urea under deficit irrigation on ear yield, nitrogen uptake, nitrogen recovery efficiency and nitrogen use efficiency, grain protein and plant nitrogen content in sweet corn (KSc 403). The experiment was carried out in strip plot arrangement based on randomized complete block design with four replications in Agricult...

Organic fertilizers preserve food cycle, reduce pollution and remediation of soil physicochemical properties and stabilization of plants in soil. To investigate the effect of organic fertilizer (vermicompost, compost and manure) on physiological characteristics of Petunia hybrida, a factorial greenhouse experiment was conducted based on completely randomized design with three replications at Fe...
