Abstract:
A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm.
Dl1aka 1207 during the period from December 2008 to April 2009 to study the role of
potassium and sulphur on the growth, yield and oil content of soybean
(Glvcine
max
var.I3ARI soybean-5). The experimental soil was clay loam in texture having pH of 6.3.
The experiment included four levels of potassium viz.. 0. 20. 40 and 70kg K ha" and Ibur
levels of sulphur viz., 0. 10. 20 and 40 kg S ha". The experiment was laid out in a
Randomized Complete Block Design with three replications. Potassium showed significant
effect oil yield and yield attributes of soybean. Application of porassiLim

lower response was found from the control treatment. The addition of K and S not only
increased the yield but also protect the soil from total exhaustion of nutrients.
