The study on influence of germination and vigour of plant growth by sowing position orientation of cashew seed was conducted at Agricultural and Horticultural Research Station, Ullal, Mangaluru, Karnataka during 2017-18. Results revealed that significantly the highest per cent seed germination was recorded in T3-notch side down position of orientation and T4- stalk end up position of orientation of seed sown (70.00 % and 6.70 %, respectively). With respect to number of leaves per plant indicated that 14, 21, 28 and 35 days after seed sowing the maximum number of leaves per plant was recorded in T3-notch side down position of orientation followed by T4- stalk end up position of orientation of seed sowing. Results on plant girth indicated that 20, 35 and 45 days after seed sowing found no significant difference among the seed sowing positions, however the plant girth ranged from 0.98 to 2.08 mm. The maximum root length was recorded in T4- stalk end up position of seed sowing (27.00 cm) followed by T5- stalk end down position of orientation seed sowing (21.50 cm).
