New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...
In order to evaluate the effect of arbuscular mycorrhizal (AM) fungi and Pseudomonas fluorescens bacteria on phosphorus fertilizer use efficiency, mycorrhizal dependence and grain yield and dry matter yield of maize under water deficit conditions, a field experiment was conducted as split-split plot arrangement based on randomized complete block design with three replications. The treatments in...
This study was performed in order to evaluate the effects of supplementary irrigation and application of Zn and K fertilizers on physiological characteristics of chickpea. The experiment was conducted in a split plot-factorial using randomized complete blocks design with three replications at campus of agriculture and natural resources, Razi University, Kermanshah, Iran. Supplementary irrigatio...
Drought stress is considered as the most important limiting factor for growing of crops such as maize. Under low irrigation conditions, proper nutrition of plants can improve the effects of drought stress. This experiment was carried out in order to investigate the effect of nutrition management along with application of zeolite on agronomic traits of two hybrids of maize under deficit irrigati...
Reclaimed water (RW) is increasingly viewed as a valuable resource for supplying irrigation water and nutrients for landscape plants growing in urban environments. A greenhouse experiment was conducted to determine if nitrogen (N) in RW contributes significantly to turfgrass plant nutrition and to measure N use efficiency and the effects of irrigation with RW on N leaching. The factorial experi...
in order to study the effects of different irrigation system and different amounts of nitrogen fertilizer on yield and quality of sugar beet, an experiment was conducted at ekbatan research station, hamedan during 2005-2006 as split plot based on randomized complete block design with three replications. the main plots were irrigation systems (furrow, sprinkler and drip irrigation) and subplots...
In order to investigate the effects of different nitrogen fertilizer levels and water stress during milky and dough stages on grain yield, yield components and water use efficiency of corn hybrid SC 704 (late maturing, non prolific and dent type), a field study was conducted. The factorial design of the study comprised of a randomized complete block with four replications. Four levels of nitro...
The application of N fertilizers with surface irrigation stream (surface N fertigation( is a key approach for fertilizer management. The main objective of this study was to investigate furrow fertigation management effects on distribution uniformity and runoff losses of nitrate in field scale. A field corn experiment was carried out with a complete randomized block design having 12 experiments....
in order to evaluate the effect of some qualitative traits of sugar beet (beta vulgaris l.) under irrigation water quality and different types of fertilizers, a field experiment arranged as split plot in rcbd design with three replications at research station of shahrekord university in 2013. the main factor include irrigation with urban wastewater at 2-4 leaf stage, 8-12 leaf stage and irrigat...
BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Improve saving water in irrigated agriculture and thereby improving water use efficiency is of paramount importance in water-scarce regions. OBJECTIVES: This study was conducted to assessment effect of different levels of irrigation re...
