Growth retardant and nitrogen levels in wheat agronomic characteristics

Study of genetic diversity in bread wheat germplasm using nitrogen uptake and nitrogen use efficiency characteristics

In order to evaluate the traits related to nitrogen utilization and to identify the superior genotypes, 33 bread wheat landraces along three check cultivars of Chamran and Koohdasht (from Iran) and Gobustan (from the Republic of Azerbaijan) were studied in simple lattice statistical design with two replications under two treatments of non-usage and application of 200 kg/ha ammonium nitrate fert...

Agronomic characteristics and baking quality of twelve wheat varieties grown in iran

growth and nitrogen use efficiency response of wheat and wild mustard to increased nitrogen levels

to investigate wheat and wild mustard growth and competition to n levels, an experiment was conducted in ramin agriculture and natural resources university of khouzestan, located at 36 km north of ahvaz. treatments included planting wheat solely, wild mustard solely, and intercropping wheat and wild mustard in pots. these combinations were exposed to n levels including 0, 60, 120 and 180 kg.ha-...

Agronomic assessment of the wheat semi-dwarfing gene Rht8 in contrasting nitrogen treatments and water regimes

Reduced height 8 (Rht8) is the main alternative to the GA-insensitive Rht alleles in hot and dry environments where it reduces plant height without yield penalty. The potential of Rht8 in northern-European wheat breeding remains unclear, since the close linkage with the photoperiod-insensitive allele Ppd-D1a is unfavourable in the relatively cool summers. In the present study, two near-isogenic...

Maize response to different water, salinity and nitrogen levels: agronomic behavior

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...
