Effect of integrated nutrient management in relation to vegetative parameters and fruiting behaviour of lemon (Citrus limon burm) cv. pant lemon-1 in sandy loam soil under western Uttar Pradesh conditions

A field experiment was carried out to study the effect of integrated nutrient management in relation to vegetative parameters and fruiting behaviour of lemon (Citrus limon Burm) cv. Pant Lemon-1 in sandy loam soil at Horticultural Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut during summer season of 2011–12 and 2012–13. Result indicated that application of 75% NPK (315g N + 210g P + 315g K) + 10kg NC + 200g PSB + 200g Azotobacter found to be statistically significant and most beneficial & promotive in relation to maximum per cent increase in tree height (14.44 and 15.34%), tree spread (16.20 and 17.68%) and trunk diameter (11.21 and 13.55) during 2011–12 and 2012–13, respectively. Similarly, maximum fruit set (79.19 and 80.54%) and fruit retention was recorded under 75% NPK (315g N + 210g P + 315g K) + 10kg NC + 200g PSB + 200g Azotobacter during 2011–12 and 2012–13, respectively. While maximum fruit drop (64.34 and 63.35%) recorded under control treatment during 2011–12 and 2012–13, respectively. Maximum fruit set and fruit retention was observed under the spring flush, however more fruit drop in autumn flush.
