an experiment was conducted to study wheat grain protein increasing through foliar application of nitrogen afterflowering. the rcbd design was analysed with three replications and four n-treatments as foliar application as(n0=0, n1=4kg.ha-1 urea, n2=8kg.ha-1 urea, n3=4kg.ha-1 ammonium sulfate). results showed that seed proteincontent increased significantly by foliar application of nitrogen. da...

A field experiment was conducted in 2010, to evaluate the effects of plant density (D1, D2 and D3: 8, 14 and 20 plant/m2) on field performance of Sorghum under different nitrogen application rates (N1, N2 and N3: application of 40, 80 and 120 kg/ha Nitrogen, respectively). The experiment was arranged as factorial based...

Previous research has demonstrated that glyphosate can affect nitrogen fixation or nitrogen assimilation in soybean. This 2-year field study investigated the effects of glyphosate application of 1.12 and 3.36 kg of ae ha(-1) on nitrogen metabolism and seed composition in glyphosate-resistant (GR) soybean. There was no effect of glyphosate application on nitrogen fixation as measured by acetylen...

in order to study the effects of nitrogen and phosphorous application on yield and physiological parameters of sugar beet polygerm seed (cv. 7233), this study was conductedin 2000-2001 in ardabil agricultural research station (alarough). the experiment was carried out with two factors including nitrogen in 4 levels (0 as control, 100, 200 and 300 kg n/ha) and phosphorous in 3 levels (0 as contr...

n order to investigate the effect of nitrogen fertilizer rates and top dressed on nitrogen remobilization in different rice cultivars, a field experiment was conducted in the rice research institute of iran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 factors were used in which fertilizer rates in 3 levels (including 46,...

A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...

effect of three different levels of fe-eddha foliar application and soil application of nitrogen on some quantitative and qualitative characteristics of apple (cv. fuji) grafted on maling-9 was evaluated. this experiment carried out at the experimental field of tehran university, in 2013. the factorial experiment was carried out as randomized completely block design (rcbd) with three replicatio...

objective: this field experiment was laid out in order to study on effect of nano and bio fertilizers on yield and yield components of tomato (lycopersicone sculentum l.) during the growing seasons 2013- 2014. methods: the experiment was laid out in a factorial based on randomized block design with three replications. treatments were k nanofertilizer in five levels such as (0, 100, 200, 300 and...
