A study on the effect of seed size (averaging 0.37, 0.62 and 0.72 g/seed) and plant spacing (12 x 50, 25 x 50 and 50 x 50 cm) on growth and seed yield of peanut was conducted during October 1985 to February 1986. The seed size did not affect growth and yield, but did the plant spacings. Both total dry matter and seed yields significantly increased with increasing plant densities. The mean seed yields for the three seed sizes of 2.26, 1.89 and 1.09 t/ha were recorded from 12.5 x 50, 25 x 50 and 50 x 50 cm plant spacing treatments respectively. Number of pods per plant was markedly increased with decreasing plant densities. The plant spacings had also no effect on hundred-seed weight and number of seeds per pod. Mean leaf area index of 0.6, 1.2 and 2.1 for the three seed sizes were recorded at fully bloomed stage from 50 x 50, 25 x 50 and 12.5 x 50 cm spacing respectively. The interaction between seed sizes x plant spacings was not observed.
