Abstract
Variety and sulphur play a significant role in the physiological growth and yield of crops such as groundnut. Even so, there has been little information on the application of variety and sulphur in groundnut. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh to investigate the effect of sulphur on yield and yield components of two groundnut varieties. The experiment comprised two varieties of groundnut viz. BARI Cheenabadam-8 and Bina cheenabadam-6; and five levels of sulphur viz. 0, 15, 30, 45, and 60 kg ha–1. The experiment was laid out in a randomized complete block design with three replications. Among the parameters leaf area index (2.03), dry matter plant–1 (50.36 g), number of primary branches plant–1 (10.33 cm), number of secondary branches plant–1 (9.27 cm), number of pegs plant–1 (46.27), number of total pods plant–1 (37.80), 100-pods weight (96.82 g), 100- seeds weight (46.25 g), shelling percentage (85.29%), pod yield (3.13 t ha–1), seed yield (2.67 t ha–1), stover yield (6.84 t ha–1), and harvest index (31.37 %) were the highest in BARI Cheenabadam-8, when treated with sulphur 60 kg ha–1. The lowest values of all these parameters were found in Binacheenabadam-6, when no sulphur was applied. This study suggested that BARI Cheenabadam-8 combined with sulphur 60 kg ha–1 could be applied for obtaining the highest yield of groundnut.

Highlights
Groundnut is an important oil-seed crop because its seed contains about 48 to 52% high quality oil, 25 to 36% highly digestible protein (Mondal and Wahhab, 2001), 20% carbohydrates, 5% fiber and Vitamin B and E which make a substantial contribution to human nutrition
To save the foreign currency and to make the country selfsufficient in edible oil, it is extremely necessary to increase the total production of oilseed crops including groundnut either by increasing their per acre yield or by increasing their acreage of cultivation or by a combination of both
The topography of the field was medium high belonging to the Sonatola soil series of grey floodplain soil under the Agro-ecological Zone-9 (AEZ-9) named Old Brahmaputra Floodplain characterized by Non-calcareous Dark Grey Floodplain Soil (FAO and UNDP, 1988)
Summary
Groundnut is an important oil-seed crop because its seed contains about 48 to 52% high quality oil, 25 to 36% highly digestible protein (Mondal and Wahhab, 2001), 20% carbohydrates, 5% fiber and Vitamin B and E which make a substantial contribution to human nutrition. It requires about 446 thousand tons of edible oil annually but it produces only about 187.0 thousand tons mainly from mustard, sesame and groundnut. The deficient is partly met mainly by soybean oil imported from foreign countries which incurs a huge amount of foreign currency to the tune of 3412 million taka annually. To save the foreign currency and to make the country selfsufficient in edible oil, it is extremely necessary to increase the total production of oilseed crops including groundnut either by increasing their per acre yield or by increasing their acreage of cultivation or by a combination of both
