to study the effects of irrigation interval and nitrogen level on yield and yield components of fenugreek medicinal plant, an experiment in split plot arranged in randomized complete block design with three replications conducted at the azad university of birjand in 2009. treatments included; irrigation intervals (4, 8 and 12 day) as main plot and nitrogen fertilizer (none fertilizer, 50, 100 a...

field experiment was conducted in order to determine the effect of wheat seeding rate and time of application of sulfosulfuron for control of hordeum spontaneum in wheat field in 2007 in qom province, iran. the experimental design was completely randomized block with four replications in which treatments were arranged as factorial. the treatments were wheat seed rates at 250, 275 and 300 kg/ha ...

this experiment was carried out in factorial arrangement based on randomized complete block design with three replications in agricultural and natural resources research center of markazi province, arak (iran) during 2008-2009 growing season. three application rates of sulphur (s1=0, s2= 40 and s3=80 kg/ha) and three rapeseed varieties (okapi, modena and licord) comprised the experimental facto...

The documentation process is very important for identifying yield constraint factors and yield gap. For this purpose, all managing practices were recorded by monitoring of paddy rice fields in Sari region, Iran from 2015 to 2016. Field identifications were undertaken in such a way that they included all the main production procedures with variations in management viewpoints. The results reveale...

The present study aims to assess the effect of Thiobacillus and sulfur on morphological and biochemical properties of medicinal pumpkinproperties under deficit irrigation based on a split-plot design. For this purpose, water stress was applied as a main factor in three levels (control, no irrigation in flowering stage, no irrigation in fruiting), and Thiobacillus and sulfur fertilizers as sub-p...

in recent years, surplus usage of chemical fertilizers and inattention the importance organic matter to improve soil fertility, leading to increasing use of chemical fertilizer, environmental pollution and etc. in order to study the different fertilizer levels (organic, chemical and combined) on yield of grain corn (s.c.704) experiment was conducted at the research farm faculty of agriculture t...

to evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in islamic azad university agricultural research station, isfahan, as a split plot in a randomized complete block design. main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...

Drought is one of the most important factors that limits N fixation, growth and yield of soybean. 2 The aim of this study was to determine the effects of water stress, starter N application and seed inoculation on yield and yield components of soybean (cv. Williams). The experiment was conducted in 2010 at the Islamshahr town that located in 12 km of South-west of Tehran, the capital of Iran. T...

In order to study the effect of irrigation interval, N fertilization and plant density on yield and yield components of fenugreek, a split-split-plot experiment was conducted in Darmian, Iran in spring 2010. The experiment was conducted in randomized complete block design with three replications. The main plots were subjected to different irrigation intervals of 5 and 10 days. The sub-plots wer...
