Use of nitrification inhibitor DMPP to improve nitrogen recovery in irrigated wheat on a calcareous soil

effects of nitrification inhibitor 3, 4- dimethylpyrazole phosphate on the yield and nitrogen use efficiency of wheat

low nitrogen (n) use efficiency is considered to be one of the major problems in wheat production fields all over the world. this experiment was conducted to evaluate the effects of nitrification inhibitor (ni) 3, 4- dimethylpyrazole phosphate (dmpp) on the yield and nitrogen use efficiency of spring wheat (triticum aestivum l.) cv. bahar during 2011 at shahrekord university. a factorial experi...

Nitrate leaching in a winter wheat-summer maize rotation on a calcareous soil as affected by nitrogen and straw management

Nitrate leaching is one of the most important pathways of nitrogen (N) loss which leads to groundwater contamination or surface water eutrophication. Clarifying the rates, controlling factors and characteristics of nitrate leaching is the pre-requisite for proposing effective mitigation strategies. We investigated the effects of interactions among chemical N fertilizer, straw and manure applica...

Relative importance of soil and climate variability for 4 nitrogen management in irrigated wheat

10 11 Abstract 12 13 Increased efficiency of nitrogen (N) fertilizer use may be achieved with management practices that account for spatial 14 variability in soil properties and temporal variability in climate. In this study, we develop a N management decision model for an 15 irrigated wheat system that incorporates hypothetical diagnostics of soil N and growing season climate. The model is the...

on the relationship between self- regulated learning strategies use and willingness to communicate in the context of writing

این تحقیق به منظور بررسی رابطه بین میزان استراتژیهای خود-تنظیم شده یادگیری و تمایل به ایجاد ارتباط دانشجویان زبان انگلیسی انجام شده است.علاوه بر این،روابط و کنش های موجود بین ریزسنجه های استراتژیهای خود-تنظیم شده یادگُیری ، مهارت نگارش و تمایل به برقراری ارتباط و همچنین تاٍثیرجنسیت دانشجویان زبان انگلیسی در استراتژیهای خود-تنظیم شده یادگیری و تمایل به برقراری ارتباط آنها مورد بررسی قرار گرفته شد.
