Abstract

A study was carried out to understand the extent of influence of seed size on pod and haulm production and also yield in groundnut, with two promising cultivars, -POL 1 and TMV 2. The study revealed that the number of mature and well-dried pods per plant was highly significant and showed positive reltaionship with seed size. 'No precise relationship was discernible between seed size and number of immature- pods per plant although there was a consistant increase in the weight of immatures as the seed size increased in both the varieties The yield of dry haulm showed significant increase with increase in seed size in both the varieties. The plot yield differences of mature dry pods obtained from crops grown from different seed sizes did assume significance, despite the high numerical increase in yield with the increase in seed size in both the varieties. On an average by using the largest seed, increased yield of mature and dry pods to the extent of 13.4 and 6.5 per cent could be obtained in POL 1 and TMV. 2 respectively.
