内容 Results of peanut spacing tests conducted on the plan shown in Table 1 are summarized as follows: 1) At thick spacing the stem grows longer and thinner, whereas branches develop less in number than at wider spacing. This trend comes forth by the time when leaves on first branch grow as come in contact with each other (Table 2). 2) Though the commencement of flowering is dependent on spacing, its termination as well as its maximum occurs earlier at the thicker spacing, the number of flowers per a plant being larger when spaced wider (Fig.1). 3) Root-, stem- and mature seed-weight per a plant reduce rapidly as spacing becomes thicker, while yeild per 10m^2 increases then so as reaches its peak at a certain width spacing (Table 3, 4). 4) 100-seedweight remains indifferent to spacing so long as this is not extremely dense (Table 3). 5) Percentage of mature shells not being definitly affected by spacing, the rates of nut per hay and fertilization rise higher when plants are spaced wider, indicating that the physiological function for plant fruiting is to be checked at thicker spacing (Table 5, 6). 6) As row breadth in practical cultivation cannot be narrower than about 60cm both for Spanish and Virginia type by reason of cultivating administration, the most proper plant population for the best yield obtained from this experiment may not be true of practical cultivation of peanuts, though a denser population than prevailing one is recomended surely. As for the most suitable hill distant it remains to be determined by later experiment.
