| dc.description.abstract | An experiment was conducted at the farmer’s field of village Bodikona, Upazila-South Surma in
Sylhet district during the period from November 2012 to March 2013 to know the performance of
lentil varieties viz. BARI masur-3, BARI masur-4, BARI masur-6 and BARI masur-7 under
traditional and relay sowing methods with T. aman rice. Design of the experiment was split plot
assigning sowing methods in the main plots and varieties in the sub-plots. Plant characters studied in
the experiment were days to 50% flowering, days to maturity, plant population m
, plant height,
number of branch plant
-2
, 100-seed weight, seed and
straw yields and harvest index. The results revealed that sowing methods produced significant effect
on days to 50% flowering, days to maturity, plant population m
-1
, number of pod plant
-1
, number of seed pod
-1
, number of
pod plant
-2
, number of branch plant
-1
, seed yield and straw yield. Significantly lower seed yield was
obtained from relay sowing than traditional method mainly because of lower plant population m
-1
, number of seed pod
-1
,
number of branch plant
-2
and seed pod
-1
and pod plant
-1
. All characters except plant height, number of branch plant
-1
differed significantly among the varieties. The variety BARI masur-7 produced the
highest seed yield (541.6 kg ha
-1
and 100-seed weight along with moderate plant population m
-1
) which was mainly contributed by the highest number of pod plant
-1
. Interaction of sowing method and
variety also exhibited significant effect on all characters except number of branch plant
-2
and seed pod
-1
, pod plant
-1
) followed by
BARI masur-4 (575.2 kg ha
-1
. Variety BARI masur-7 produced the highest seed yield (614.8 kg ha
-1
) in the traditional method of sowing attributed by the higher plant
population m
-1
and 100-seed weight. These two varieties performed better in
both the sowing methods. BARI masur-7 gave maximum gross margin (Tk. 7524 ha
-2
, number of pod plant
-1
) in relay
method which was followed by gross margin (Tk. 5878 ha
-1
-1
) of the same variety in traditional method. | en_US |
