In order to investigate the effect of chemical and biological nitrogen fertilizer on canola, a field experiment was conducted as a split plot based on a randomized complete block design with three replications at the research station of the Faculty of Agriculture, Yasouj University, located in Deshtrum region, in 2019. The main factor consisted of nitrogen fertilizer (zero, 25, 50, 75, 100 and ...

To determine the proper nitrogen fertilizer rates and its application times for achieving high grain and oil yields of rapeseed cultivar, Hyola 401, a research was carried out in paddy fields of Rice Research Institute of Iran in Rasht during two cropping seasons. A factorial experiment was conducted in a completely randomized block design with three replications. The experimental factors w...

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.

In order to study the effects of nitrogen application rate and timing on grain yield, phyllochron and leaf appearance rate of corn (Zea mays L.), an experiment was conducted as split plot based on randomized complete block design with three replications at the Research Farm of University of Mohaghegh Ardabili, Ardabil, Iran during 2009 growing season. Nitrogen rates were arranged in main plot w...

In order to study the effect of soil nitrogen content and water hardness on glyphosate efficacy on common lambsquart control, an experiment was carried out as a completely randomized design in a factorial arrangement with three replications in 2011 at the College of Agriculture, Ferdowsi University of Mashhad. Experimental treatments were included soil nitrogen content at 5 levels (0, 50, 90, 2...
