Abstract:

A research work was carried out with a view to evaluate lentil (Lens culinaris) varieties at different sowing dates from October 25 to December 6 against Stemphylium botryosum in Bangladesh during winter season of 2012-2013.Two lentil varieties viz., BARI Masur-1 and BARI Masur-7 were evaluated at seven different sowing dates viz., October 25, November 1, November 8, November 15, November 22, November 29 and December 6 in RCB design with three replications. Significant differences were found in percent disease incidence for sowing dates and varieties. The highest disease incidence (72.50%) was recorded from the plants grown from October 25 sowing which was statistically identical to that of November 1 (63.5%), November 15 (62.17%) and November 22 (62.17%). However, disease incidence was drastically reduced at November 29 (42.17%) and December 6 (30.83%) sowings. The variety BARI Masur-1 was found more sensitive (64.0%) to that of BARI Masur-7 (47.0%) to stemphylium disease. The average highest seed yield was obtained from November 8 sowing (1200 kg ha-1) which was statistically identical to that of November 15 sowing (1156 kg ha-1). Between two varieties, BARI Masur-7 was more productive (1131 kg ha-1) than that of BARI Masur-1 (789 kg ha-1). The maximum seed yield ha-1 (1399 kg) was achieved from BARI Masur-7 when grown from November 8 sowing followed by November 15 sowing (1314 kg ha-1) by the same variety indicating first fortnight of November might be more productive for BARI Masur-7.
