Abstract
The experiment was carried out at the research field of Sher-e-Bangla Agricultural
University, Dhaka, during the period from 10 November 2010 to 10 March 2011 to
investigate the effect of potassium and sulfur on morpho-physiological characters, yield
attributes and yield of potato. The experiment comprised of four different doses of
potassium (0, 117, 130, 43 kg ha
-1
) along with sulfur (0, 24, 29 and 34 kg ha
). The
experiment was laid out in split plot design with three replications. The growth
parameters such as plant height, stems hill
-1
, leaves hill
-1
-1
, total dry mass (TDM) plant
and TDM m
-2
, yield attributes such as tubers hill
-1
and single tuber weight and tuber yield
and marketable yield were significantly influenced by potassium and sulfur. Results
revealed that, number of leaves hill
-1
, stems hill
-1
, plant dry matter content, tuber dry
matter content, tubers m
-2
, seed yield, marketable yield significantly increased with
increasing potassium levels, whereas, plant height decreased with increasing potassium
level. On the other hand plant dry matter content, tuber dry matter content, stems hill
,
tubers m
-2
, seed yield, marketable yield increased significantly with increasing sulfur
level. While plant height, number of leaves hill
-1
and tubers m
-2
decreased with increasing
sulfur level. Combined effect of potassium and sulfur reveled taht the highest number of
tubers m
-2
was achieved by 130 kg potassium ha
-1
with 34 kg sulfur ha
. But 130 kg
potassium ha
-1
with 29 kg sulfur ha
-1
produced more 45-55 mm sized tuber than 130 kg
potassium ha
-1
with 34 kg sulfur ha
-1
. Application of 130 kg potassium ha
with 34 kg
sulfur ha
-1
produces more <28 mm sized tuber than that of 130 kg potassium ha
with 34
kg sulfur ha
-1
. Finally 130 kg potassium ha
-1
with 29 kg sulfur ha
-1
produced numerically
highest yield but statistically similar with 130 kg potassium ha
-1
-1
-1
-1
with 34 kg sulfur ha
