Nitrogen fertilizations strongly influence the wheat growth particularly in N deficient soil. The objectives of this study were to quantify the effect of N sources on emergences, growth rates, chlorophyll content, phyllochron and dry matter of wheat. Wheat (AC Barrie variety) was grown in glasshouse at the University of Bangor, Wales, UK for 31 days in pots having five N treatments i.e. ordinary soil, 100 kg N ha-1 as nitram, compost, farmyard manure (FYM) @ 12.5 and 25 tons ha-1. The glasshouse was set at temperature of 18 and 20�C during night and day, respectively with a day length of 16 hours and relative humidity of 65-70%. Nitram N delayed emergence of seedling, improved chlorophyll contents, leaf length, and plants tallness. Linear elongation rate and leaf appearance rate of the leaf were greater for organic N over control. Linear elongation rate was decreased with appearance of leaves. Phyllochron values (�C days) were decreased as the number of leaves on primary tiller increased. In conclusion, the effects of inorganic N attributed to a reduced leaf numbers and increased leaf elongation rate, whereas organic source of N had increased growth and root dry matter in addition to leaf appearance.
