Tillage methods are among the most successful factors in agriculture that have a significant impact on the quality and quantity of agronomic plants. To evaluate different tillage methods and urea fertilizer with nitrapyrin on total chlorophyll content, grain protein, yield, and yield components of two barley (Hordeum vulgare L.) cultivars, an experiment was conducted as split factorial in the r...

The effect of N levels and planting densities on quantitative and qualitative characteristics of grain yield in grain sorghum (cv. Kimia) was studied in summer 1998 at Kushkak Agricultural Research Station, Shiraz University. The experiment was a spilt plot with 4 replications in which 4 levels of planting densities (7.7, 10, 15.4, 20 seeds m-2) were applied as main plots and 4 levels of N (0, ...

The present study aims to investigate the effects of nitrogen fertilization and municipal waste compost on yield, yield components and some of the grain macronutrients of sweet corn. A field experiment was carried out as a split plot in randomized complete block design with three replications in 2015 at Agriculture and Natural Resources Research Center Zarghan-Fars, Iran. The main plot consiste...

Effect of potassium and magnesium fertilizers on safflower grain yield was studied, using a factorial experiment based on completely randomized block design with three replications at the Agricultural Research Station of University of Mohaghegh Ardabili in 2011. The treatments consisted of potassium fertilizer with three levels (0, 60 and 120 kg ha-1) and magnesium fertilizer (0, 75 and 150 kg ...

In order to investige the effect of nitrogen and Azospirillum biological fertilizers on the growth and yield of an Iranian bread wheat (Roshan cultivar) this study was carried out using a factorial experiment based on a randomized complete block design with three replications at a field in Jozan region, Isfahan, Iran in 2013. The experimental factors included Azospirillum brasilense bacterium a...

To investigate the effect of nitrogen and zinc elements on the quantity and quality characters of sunflower plants (Jamah1cultivar), a factorial experiment in a randomized complete block design with three replications was conducted at the University of Zabol, Zabol, Iran in 2013. The experiment consisted of three nitrogen levels: 100, 200 and 300 kg ha-1 as the first factor and three levels of ...
