In Bangladesh, lentil (Lens culinaris Medikus subsp.culinaris) production was 0.26 million tons from 0.20 million hectares (average yield 1.3 t ha-1) which is 29 % of the total national pulse production (AIS, 2016). Globally, it is cultivated as a rainfed crop on 3.85 million hectares (m ha) with a yield of only 1.1 t ha-1 (Erskine et al., 2011). In rice based cropping patterns, after harvesting of t.aman rice maximum land remains fallow for about 90 days until establishment of the boro rice. Presently, this rice land cannot be used to grow lentil since varieties have 110-115 days duration (AIS, 2017). Promising biofortified short duration (83-90 days) lentil varieties can play an important role to expand its cultivation through establishing lentil by relay sowing into t.aman rice and harvesting before boro rice. The relay cultivation method involves no tillage and residue retention, and establishes the lentil before t.aman rice is harvested. The selection of promising biofortified short duration lentil genotypes under relay cultivation method is therefore important to accommodate in fallow between t.aman and boro rice
