Abstract:
An experiment was conducted at the research Field of Sher-e-Bangla Agricultural
University, Dhaka, during the period from February to June, 2014 to study the effect
of potassium and sulphur on the growth and yield of BARIMash-1. The treatment
consisted of four level of potassium viz. K
0
= 0 kg/ha, K
1
= 12 kg/ha, K
= 18 kg/ha,
K
3
= 24 kg/ha and three different level of sulphur viz. S
0
= 0 kg/ha, S
= 10 kg/ha. The experiment was laid out in a randomized complete block design
(RCBD) having three replications. Each replication had 12 unit plots to which the
treatment combinations were assigned randomly. Seeds (v.BARIMash-1) were sown
at the rate of 25 kg ha
-1
in the furrow. Necessary intercultural operations were done
as and when necessary. The collected data were statistically analyzed for evaluation
of the treatment effect. Results showed significant variation among the treatments in
respect of the majority of the observed parameters and yield. Potassiun @ 24 kg ha
gave the highest plant height, length of pod, number of pods per plant, number of
seeds per pod, thousand seed weight. The highest yield of seed (1505.00 kg ha
) was
recorded in 24 kg ha
-1
. Similarly, the highest number of pods per plant, number of
seeds per pod, thousand seed weight, seed yield (1494 kg ha
-1
) was recorded with 10
1
2
= 5 kg/ha, S
-1
2
-1 kg S ha
-1
. The interaction between different levels of K and S was significant for
almost all studied parameters and seed yield. The highest seed yield (1528 kg ha
)
was recorded with the combination of 24 kg K and 10 kg S ha
. The yield
components also attained the maximum results from the said treatment combination.
Concentrations of N, P, K and S in blackgram stover were influenced significantly
due to combined application of K and S. The highest concentrations were obtained
-1
-1with the combination of 24 kg ha
-1
K and 10 kg ha
-1
S application. As the tested crop
responded linearly due to application of K and S, therefore further higher dose may
be used for maximizing the yield of blackgram in the study area (AEZ-28).
