Study on the effects of hilling up on yield of groundnut cultivars CES 101 and Tainan 9 was carried out under highland conditions (1175 m. above sea level) at Chang Khian Highland Agricultural Research Station during June to October 1987. The hilling up treatments studied were no hilling up, 1 hilling up at 15 DAE, 2 hilling up at 15 and 30 DAE, and 1 hilling up at 30 DAE. Hilling up gave a marked increase in seed yield in both groundnut cultivars. No significant difference in yield was observed among the hilling up treatments. The cultivar CES 101 performed better than Tainan 9, with average yields being 329.3 and 312.3 kg/rai, respectively. No interaction between groundnut cultivars and hilling up treatments for yield was found. Analysis of yield components and shelling percentage also showed that there was no significant difference in number of pod per hill and number of seed per pod among the hilling up treatments, but these characters were higher than those of the no hilling up treatment. CES 101 had higher number of seed per pod, seed weight, and shelling percentage than Tainan 9.
