Experiment was conducted during 2007 growing seasons at the Field of College of Agriculture, Tarbiat Modares University, Tehran Province, Iran to study the effect of biofertilizers (Azosporillum and Azotobacter), nitrogen fertilizer (N) and farmyard manure (FYM) in various rates on the grain and biological yield, seed protein content as well as seed oil content and fatty acid composition in sun...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
this research was conducted to study the effects of water deficiency stress, nitrogen application rates, and plant population on water use efficiency and nitrogen of oily sunflower in 2007-2008 agriculture and research center of west-azerbaijan. the study was consisted split-split-plot experiments using randomized complete block design with 3 replications. the factor main was consisted irrigati...
introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...
this study aims to investigate value conflicts between mothers and their daughters among families and influential factors on this conflict in yazd city. this study adopted a survey method and a questionnaire was used that its validity through construct validity (factor analysis) and its reliability by cronbach alpha were measured. the population of this study consists of all yazdian families th...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
To clarify the effect of deep rooting on grain yield in rice (Oryza sativa L.) in an irrigated paddy field with or without fertilizer, we used the shallow-rooting IR64 and the deep-rooting Dro1-NIL (a near-isogenic line homozygous for the Kinandang Patong allele of DEEPER ROOTING 1 (DRO1) in the IR64 genetic background). Although total root length was similar in both lines, more roots were dist...
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...
In order to investigate the effect of nitrogen management on morphophysiological traits, yield and yield components of corn hybrids, the present experiment was carried out in a split plots arrangement in a randomized complete blocks design with three replications in a field located in Ahvaz city during the crop year 2016-2017. Experimental treatments consisted of nitrogen fertilizer management ...
