Lentil is an important legume crop in Bangladesh for food, feed and cropping system. It has also immense contribution to soil fertility and agro-based industries. Despites of its necessity, there are many constraints in lentil production in southern region of Bangladesh. Hence, growth and yield of lentil (Var. BARI Masur 7) were evaluated at two types of row spacing viz. 30 cm and 40 cm, and three types of stubble height of Transplant Aman rice viz. no stubble residue, 15 cm height and 30 cm height stubble residue under strip tillage system at Rahmatpur, Barishal, Bangladesh. Results reveal that treatment combination of 30 cm row spacing and 30 cm stubble height showed best performance in seed yield (1.36 t/ha), stover yield (1.56 t/ha) and harvest index (46.6%). The lowest incidence of foot rot (1.3 %) and stemphylium blight (1, scale: 0-5) diseases were observed in this treatment combination. In conclusion, treatment combination of 30 cm row spacing and 30 cm stubble height will be suitable one for increasing production of lentil at southern region, especially Barishal division of Bangladesh.
