Assessment of coherent impacts of selenium and urea on the growth and physiological attributes of wheat (Triticum aestivum L.)

A study was conducted to examine the effect of selenium and urea on the growth of wheat plant. Plants were grown in the pots by using different concentrations of selenium and urea. The treatment levels were in the form of control with 0 % urea and selenium while others were kept as (4 mg SeL-1 + 1% urea), (4 mg SeL-1 + 3% urea), (4 mg SeL-1 + 5% urea) and (6 mg Se L-1 + 1%), (6 mg SeL-1 + 3%), (6 mg SeL-1 + 5%). Observed growth parameters were root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight, leaf length, grain weight, total plant height while physiological were chlorophyll a and chlorophyll b content, and percentage of nitrogen, proteins, starch, lipids, iron and zinc in the grain. Results showed that there was significant increase in both growth and physiological parameters with increasing concentration of combined urea and selenium as compared to that of control.
