Abstract
Study of spacing for irrigated bunch groundnut conducted during August, to December seasons of 1965 to 1967 at Bhavanisagar showed that varving the plant-space under a constant row space decreased the height of main stem and length of primary branches and increased the number of secondary branches, flower production and number of mature and immature pods per plant. The closer spacing of 15 x 15 cm recorded 34.1 per cent increased yield over 21.5 x 15 cm (standard) while all the other spacing treatments produced lower yield. A spacing of 15 x 15 cm with a seed rate of 150 kg/ ha yielded 1,569 kg of pod and resulted in a net income of Rs. 1231/ ha which was Rs. 548/ more than that recorded under 22.5 x 15 cm,
