Six treatment Viz. 50, 100,150,200, 250, 300 kg/ha of Nitrogen with same level of P and k (160:100 kg/ha) and FYM (20 t/ha) were used in a Randomized Complete Block Design with three replications. Effect of treatments on plant height, leaf area and head weight plant<sup>-1</sup>, yield ha<sup>-1</sup> were significant and other parameters (leaf number, SPAD reading, plant spreading) were not affected by the treatments. Treatment that received 300 kg N ha<sup>-1</sup> gave the maximum yield ha<sup>-1 </sup>(14.77 ton) which was followed by treatment that received 250 kg N ha<sup>-1 </sup>(10.60 ton), 200 kg N ha<sup>-1</sup> (8.11 ton), 150 kg N ha<sup>-1</sup> (7.432 ton), 100 kg N ha<sup>-1</sup> (5.96 ton) and 50 kg ha<sup>-1</sup> (4.24 ton). Treatments 250 kg N ha<sup>-1</sup>, 200 kg N ha<sup>-1</sup>, 150 kg N ha<sup>-1</sup> and 100 kg N ha<sup>-1</sup> were statistically at par while 50 kg produced the least yield ha<sup>-1</sup>. Application of 300 kg N ha<sup>-1</sup> gave the higher result with respect to plant height (17.75 cm), leaf area (699.32 cm<sup>2</sup>), leaf number (7.77), SPAD reading (68.71), plant spreading (70.21 cm), compared to other treatments while minimum result obtained from application of 50 kg N ha<sup>-1</sup>. Hence, we can conclude that the total head production increased with increased N </p><p><em>Int. J. Appl. Sci. Biotechnol. Vol 6(3): 270-273</em></p> ER -
