The optimum seed rate of lentil is …………….. kg/ha.

✅Explanation: lentil, (Lens culinaris), small annual legume of the pea family (Fabaceae) and its edible seed. Lentils are widely cultivated throughout Europe, Asia, and North Africa but are little grown in the Western Hemisphere. The seeds are used chiefly in soups and stews, and the herbage is used as fodder in some places.  The optimum seed rate for lentil cultivation is generally 30-40 kg per hectare. This seeding rate ensures proper plant density for optimal growth, light interception, and yield while minimizing competition between plants for resources.
