In order to study the effects of simultaneous application of nitrogen (N) and ZnSO4 fertilizers and biofertilizer (Azotobacter and Azospirillum) on grain yield and growth traits of rapeseed, Hyola308 cultivar, a field experiment, with split plot factorial layout based on randomized complete blocks design with three replications, was conducted at Research Field of Faculty of Agriculture, Univers...

 This study was designed and conducted to investigate on physiological growth indices and photosynthetic pigments in three maturing corn (Zea mays L.) hybrids (SC704, SC500, and SC260) using four nitrogen (N) levels (0, 80, 160, and 240 kg N ha-1, from Urea, N= 45%). The experiments were conducted in Zabol and Isfahan in 2014 and 2015, respectively, using the split-plot arrangement in a randomi...

In line with sustainable agriculture development, an experiment was conducted including tillage as the main factor in two conventional systems (plowing and mixing fertilizer with soil) and no tillage (leaving residuals of green manure and direct corn sowing). The fertilizer resources were T0: control, T1: barley green manure without chemical and manure fertilizers, T2: barley green manure with ...

The aim of this study was to investigate the influence of different nitrogen sources on qualitative and quantitative characters and economic benefit of potato (Sante cultvar). This experiment was conducted in a randomized complete block design with four treatments and three replicates at Behbahan Agriculture Research Station, Behbahan, south-east Iran, in two years (2014 and 2016). Treatments w...

The use of nitrogen fertilizer has a key role in enhancing agricultural productivity worldwide. In order to achieve an effective approach to enhance nitrogen use efficiency in rice, a field experiment was conducted in a randomized complete block design with three replications and 13 treatments on Shiroudi, a high yielding rice cultivar in Rice Research Institute of Iran (Amol) in 2015 and 2016....
