Experiments were carried out in 1986 at the experimental farm of An Sung Agricultural Technical College, to determine the ecological responses of peanut cultivars to different seeding date and densities. Cultivars representing three plant types. ie. Runner. Semi-runner and Spanish types were chosen and planted of April 20. May 10 and May 30. The results obtained are summarized as follows; 1. Main stem of the spanish type was longer than that of the Runner type cultivars, Stem length tended to longer for early seeding date than for late seeding date. 2. Number of branches per plant was significantly greater for runner types than spanish types. For the late seeding date, the number of branches decreased significantly more for runner type cultivars than for semi-runner or spanish types. 3. The longest branch of runner type plants was longer than those of either semi-runner or spanish type. 4. Top dry weight per m^2 of Runner type were much more than that of spanish type, black were sowed at May 10 were most heavy in top dry weight per m^2 and increasing rat of top dry weight per m^2 was most heavy from Jul. 10 to Aug. 31. 5. Dry pod weight per m^2 was recognized that increasing rate of dry pad weight in Runner type is biggest at Aug. 24 that in Semi-runner and spanish type increased from Aug. 9, but decreases from Oct. 8. 6. C.G.R of top dry weight stage were peak of two stage, such as just before the reproduction stahe and fruiting stage. 7. Number of pods per plant of nunner type, earlier seeding, spare planting increased more than that of Spanish type, later seeding. 8. 100 grain weight in block was sowed at May 10, increased more than in block was sowed at Apr. 20, but the more seeding date delayed, the more it reduced. 9. Pod yield was order of Spanish, semi-runner, runner type, variation on seeding date showed the same trend as 100 grain weight plant.
