Abstract

The field experiment entitled Effect of Seed Rate and Nitrogen on Growth and Yield Attributes of Wheat (Triticum aestivum L.) was conducted, in the experiment comprising a total 12 treatment combinations; such as three seed rates (100, 125 and 150 kg/ha) and four levels of nitrogen (75, 100, 125 and 150 kg/ha). Which was carried out in split plot design with three replications. Results revealed that the growth, yield and economics of wheat significantly differed with different seed rates and nitrogen levels. Results showed that crop sown using seed rate of 100 kg/ha recorded significantly higher plant height, spike length, number of grains per spike and test weight as compared to 125 and 150 kg/ha seed rates. Higher dry matter accumulation, number of tillers per meter row length and straw yield recorded with seed rate of 150 kg/ha over 100 and 125 kg/ha. However, significantly higher grain yield and biological yield, net returns and B: C ratio were recorded with the seed rate of 125 kg/ha as compared to seed rate of 150 and 100 kg/ha. Among nitrogen levels, significantly higher plant height, dry matter accumulation, number of tillers per meter row length, spike length, number of grains per spike and test weight, grain yield, straw yield and biological yield, net returns and B: C ratio recorded with the application of nitrogen @ 125 kg/ha as compared to application of nitrogen @ 75 and 100 kg/ha, but it was at par with the application of nitrogen @ 150 kg/ha as compared to 125 and 150 kg/ha seed rates.
