Abstract
A field experiment was conducted at Sher-e-Bangla Agricultural University during the
period from November 2021 to March 2022 to evaluate the influence of micronutrient
management on growth and yield of two lentil varieties viz. BARI Masur-8 (V
1
) and
Binamasur-8 (V
2
) and 6 micronutrient management (No fertilizer - F

). No significant effect had found for variety except 1000-seed weight but
micronutrient management along with interactions significantly effects on all studied
parameters of lentil. The higher 1000-seed weight (34.16 g) was recorded in BARI Masur8.

The highest number of nodules plant

So, the two studied varieties showed similar
performance on yield. Foliar application of Zn has the potentiality to increase seed yield.
Application of Zn is important for lentil cultivation. The variety Binamasur-8 with 50 %
RFD + 50 % cowdung + Zn & B (F

) of lentil that also similar with F

) as foliar spray could bring maximum yield (2.91 t ha

. Variety BARI Masur-8 gave the highest
seed yield (2.79 t ha

) with F

that similar with F

and F

.
