Study was conducted at Pakchong Animal Nutrition research Centre to determine the effect of plant spacing on seed yield and quality of Arachis pintoi cv. Amarillo. Arachis was established from seed in different spacing: 50*25 cm (8 plant/square m) 50*33 cm (6 plants/square m), 50*50 cm (4 plants/square m) and 100*50 cm (2 plants/square m). Plot were aranged in Randomized complete block design with 4 replications. Seed were harvested at 20 months after establishment. Pure seed yield obtained from plant spacing of 50*25 cm was 867 kilogram per rai and at 50*33 cm spacing was 780 kilogram per rai which were significantly higher than that from planted at 100*50 cm (495 kilogram per rai). Plant spacing did not affect on seed quality of A. pintoi the mean 1000 seed weight ranged from 151-184 gm. Purity ranged from 83.7-91.6 percent Germination ranged from 47.9-63.1 percent.
