Abstract:
An experiment was carried out to evaluate the influence of variety and phosphorous
on growth and yield of lentil at Sher-e-Bangla Agricultural University farm, Dhaka,
Bangladesh during November, 2015 to March, 2016. The experiment comprised of
two factors viz. i) Factor A: three lentil cultivars V

= BARI
Masur 6 and V

= BARI Masur 7 and ii) Factor B: four levels of phosphorus P

The
experiment was laid out in split-plot design with three replications where lentil
varieties were assigned in the main plot and levels of phosphorous in the sub-plot.
Variety of lentil showed significant influences on most of the growth, yield and yield
attributes of lentil. The highest seed yield (1.44 t ha
-1
) was observed in BARI Masur 6
while the lowest in BARI Masur 7 (1.03 t ha
-1
). Phosphorus fertilizers had a
significant effect on the growth, yield and yield attributes of lentil. The highest seed
yield (1.46 t ha

) was recorded from 40 kg P

effect on most of the growth, yield and yield attributes of lentil. The highest seed
yield (1.72 t ha

. Addition of phosphorus fertilizer beyond 40 kg ha

decreased seed yield
irrespective of varieties. Application of phosphorus fertilizer at the rate of 40 kg P

could be a best production package for lentil production irrespective of varieties
in different lentil growing regions of Bangladesh.
