Abstract: A field experiment was conducted at BCKV during rabi, 2018-19 to study the effect of Zn, Fe and B foliar spray on phenology, growth and yield of popular lentil variety; Moitiri(WBL 77) under different sowing condition (1st week of November and 1st week of December). Delay in sowing though reduce the yield in second date of sowing, a foliar spray combination of B+Fe @0.5% recorded almost double the yield (1431 kg ha-1) than control (748 kg ha-1). Delay in sowing of crop from November 1st week to December 1st week reduced the duration by 11.67 days (113.41 days vs 101.74 days). Mean days of lentil from sowing to emergence, flower initiation, pod initiation and maturity for first date of sowing were 8.0, 47.81, 16.22 and 41.52. The crop completed these respective stages in 10.96, 38.39, 20.63 and 31.26 days in second date of sowing, respectively. The treatment with B+Fe+ Zn @ 0.5% through recorded highest plant height (49.22), highest nodule number (30.83) and no. of flowers (323.17), the highest yield was recorded in B+Fe @0.5% (1431.11 kg ha-1). This is mainly because of the completion among the flowers because of more number of flowers resulting in more flower drop and less number of pods.
