Abstract
The experiment was conducted in the Agronomy Farm of Sher-e-Bangla Agricultural
University, Dhaka during the period from November 2015 to March 2016 to find out
the effect of variety and potassium on the yield of lentil under residual soil moisture
condition. The experiment consisted of two factors: Factor A: Three varieties of
lentil (V

: BARI masur-5, V
2
: BARI masur-6, V
3
: BARI masur-7). Factor B: 4 doses
of Potassium fertilizer (P

). There were 12 treatment combinations. The experiment was
laid out in Randomized Complete Block Design (RCBD) with three replications.
Variety, potassium level and their interactions had significant influence on water
relations, yield contributing characters and yield of lentil. The maximum relative
water content, exudation rate, grain yield (1.05 t ha

) and biological yield (2.38 t ha
) were found in BARI Masur-7 whereas the minimum in BARI Masur-5. The
maximum relative water content, exudation rate, grain yield (0.99 t ha
) and
biological yield (2.20 t ha

) were also found from 40 kg K
