Yield and lodging related traits are essential for improving rapeseed production. The objective of the present study was to investigate the influence of plant density (D) and nitrogen (N) rates on morphological and physiological traits related to yield and lodging in rapeseed. We evaluated Huayouza 9 for two consecutive growing seasons (2014-2016) under three plant densities (LD, 10 plants m-2;...

to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...

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...

in order to study the effects of simultaneous application of znso4 and biological fertilizer, azotobacter chroococcum and azospirillum brasilense, on grain yield and nitrogen uptake efficiency in rapeseed (brassica napus l.), cv. hyola308, a field experiment was conducted as split plot factorial based on randomized complete block design at research field of faculty of agricultural sciences, uni...

in order to investigate the effects of nitrogen application rates and different planting beds on yield and yield components of garlic (allium sativum l.), a field experiment was conducted as split plot based on a randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, iran, during 2009-2010. three nitrogen application rates ...

to study the effects of simultaneous application of urea, znso4 and inoculants, (azotobacter and azospirillum), on uptake and nitrogen use efficiency in rapeseed, var. hyola308, a field experiment with split plot factorial layout based on a randomized complete block design was conducted at the research field of faculty of agricultural science, university of guilan in 2008. experimental treatmen...

Soil water, salinity and nitrogen content are three major factors affecting crop production in arid and semi-arid areas. This study was performed in two years of 2009 and 2010 in a semi-arid area in order to investigate the effects of irrigation water quantity (as main plot), quality (saline water, as sub-plot), nitrogen fertilizer (as sub-sub plot) and their interactions on growth and yiel...

In this study the effect of four levels of nitrogen fertilizer (0, 50, 100, 150) kg/ha and four levels of super phosphate triple (0, 50, 100, 150) kg/ha were investigated on Rubia Inctorum L. (madder) under salinity stress. A factorial experiment was carried out in a research farm in Roaddasht, Isfahan based on complete randomized blocks with three replications. The results of the variance anal...

in order to study the competition effects of redroot pigweed (amaranthus retroflexus) and millet (panicum miliaceum) on maize performance under different rates of n fertilizer, a field experiment was conducted in 2009 in the research fields of tarbiat modares university in tehran as a randomized complete block design with factorial arrangement of treatments and three replications. accordingly, ...
