Varietal Roles on Morpho-physiological and Yield Attributes of Lentil (Lens culinaris Medik)

Background: Lentil is the top cultivated pulse crop in Bangladesh. Even if there are a number of modern high yielding varieties (HYV) with all natural favorable conditions and resources for cultivation but due to lack available stress and climate (biotic and abiotic) resilient variety; potential yield of this crop is rarely met. Against huge sum of demand the supply is deficit in the country which is met by importing. Reflecting this situation, the present investigation attained to test the morpho-physiological and yield related attributes of seven HYV of lentil and depict the most suitable variety in terms of growth, yield and maturity. Methods: Binamasur-5, Binamasur-8, Binamasur-9, Binamasur-10, BARI Masur-5, BARI Masur-6 and BARI Masur-8 was laid in a randomized complete block design during the rabi (winter) season of 2019 at BINA sub-station farm, Magura. Result: Findings divulged that, Binamasur-10 had the most seed yield (2.08 t/ha), harvest index (HI) (25.15%) and with medium duration of maturity (108.94 days). BARI Masur-5 produced maximum stover yield (7.86 t/ha) with delayed maturity (114 days) and least seed yield (1.75 t/ha) among the evaluated varieties. Correlation study exposed that, seed yield had a positive and significant relationship with plant height (0.78*), number of primary and secondary branches (0.76* and 0.75*), total dry mass (0.87**) and HI (0.85**). However, Binamasur-10 might be more suitable than the other varieties in the field due to it’s notable performance.
