YIELD PERFORMANCE OF BINA DEVELOPED LENTIL VARIETIES
The field experiment was conducted at research farm of BINA sub-station Ishurdi during the winter (rabi) season, 2016-2017 to find out the best yield performance of BINA developed lentil varieties that are able to increase lentil production in Bangladesh within short maturity period. BINA developed nine lentil varieties (Binamasur-1, Binamasur-2, Binamasur-3, Binamasur-4, Binamasur-5, Binamasur-6, Binamasur-7, Binamasur-8 and Binamasur-9) were tested in Randomized Complete Block Design (RCBD) with three replications to evaluate their morphological and yield contributing characters. The performance of Binamasur-8 is the best for maximizing seed yield with short maturity period. Binamasur-8 produced 2.37 t ha-1 yields with 88 maturity days. Primary branch production is more important than plant height in achieving higher seed yield in lentil. More primary branches ensure more pod number which also increase seed number and finally produce more seed yield. Seed size was also responsible for high yield achievement. Among all the BINA developed lentil varieties Binamasur-8 was found pioneer followed by Binamasur-5 in respect of seed yield with earliest maturity period. Therefore, it will be possible to increase lentil production in Bangladesh by cultivating Binamasur-8.
