Abstract:
Experiment was conducted during <em>rabi</em> season of 2015-16 at the Agricultural Research Farm Dhablan of the G.S.S.D.G.S. Khalsa college Patiala, Punjab. The experiment consisted of two factors viz. three nitrogen levels (N<sub>0, </sub>N<sub>100, </sub>N<sub>150 </sub>kg/ha) in main plots and four zinc levels (Z<sub>0, </sub>Z<sub>1.5,</sub> Z<sub>3</sub>, Z<sub>6</sub> kg/ha) and was laid out in a Factorial Randomized block design replicated thrice. Cobs/plant, length of cob, number of grains/cobs, 1000-grain weight and weight of cobs increased with all fertilizer rates consistently and significantly over control. Nitrogen 150 kg/ha and zinc 6 kg/ha gave maximum 1000-grain weight (445.0 g), length of cob (19.20 cm), cob weight (240.40 g), number of grains/cob (368.30), grain yield (41.80 q/ha), stover yield (251.0 q/ha) and B.C ratio (2.62) followed by nitrogen 100 kg/ha and zinc 3 kg/ha.
