Investigating the Impact of Nitrogen and Seed Rates on Morpho-physiological Responses in Dual Purpose Wheat (Triticum aestivum L.)

Growing crops for dual purpose i.e. both grains and fodder together may be a good option for
reducing the burden of growing alarming human population. Wheat may be a better option to mitigate
the shortage of grains as well as fodder. Many works have been carried out in this direction
considering wheat but the production has been a limitation. Among various agronomical methods,
modifications of fertilizers concentrations and seed rate are very crucial which affect yield. Nitrogen is
one of major components of fertilizers which plays crucial role in crop growth influencing major
physiology including photosynthesis, protein synthesis, nucleic acids synthesis etc. Seed rate is
directly related to canopy expansion and solar radiation interception, thereby strongly influencing the
use of environmental resources by changing relative importance of intra and interplant competition for
light, water and nutrients during crop development and thereby affects wheat yield. Looking at the
importance of the issue, this review was carried out to get the information about the effect of seed
rates and nitrogen levels on the forage and grain yield of dual purpose wheat genotypes for enhanced
productivity. Growing dual purpose wheat is gaining enhanced importance. Parameters discussed in
the manuscript may be taken into consideration for increased productivity. Deep physiological and
biochemical insights are required for understanding the factors controlling both vegetative growth and
grain development in wheat for serving both dual purposes.
