Field experiments were conducted during 2015-16 and 2016-17 to study the effect of irrigation and N levels on growth and yield of onion (Allium cepa L.) in Himachal Pradesh. Twelve treatment combinations comprising four irrigation level . 4 cm irrigation at IW/CPE ratio (I1), (I2), (I3), (I4) and three N levels . 75 (N1), 100 (N2) and 125 per cent (N3) of recommended dose of N, were replicated thrice in a Randomized Block Design. Growth parameters viz. Bulb yield, number of leaves, leaf length, equatorial diameter, polar diameter and TSS were at par under I1 and I2 levels and superior over I3 and I4. Among N levels, 125% of the recommended dose (N3) was found to be optimum as it recorded significantly higher growth and yield of onion crop over N2 and N1 levels. The combinations of irrigation and N levels viz. I1N3 and I2N3 gave significantly higher bulb yield ( q ha-1 and q ha-1 ). The study has led to a conclusion that for maximizing growth and yield of onion in Himachal Pradesh, 4 cm irrigation at IW/CPE ratio and 125 per cent of recommended dose of N (I2N3 ) could be the best. | Effect of irrigation and nitrogen levels on growth, yield and quality parameters of onion (Allium cepa L.) in Himachal Pradesh, India
