    Abstract

    Crop density can be managed by row spacing. However, the use of wide row spacing will lead to in efficiency of land use. On the other hand, narrow row spacing can disrupt growth and development of crops owing to the lack of radiation wtrich is received by the crops. Consequenfly, it will disrupt photosynthesis process. Estimation of growth rate and developmeni of plant induding radish based on the ciange of a plant per number of days after planting is not appropdate. Therefore, potential biomass production which is determined by the use of sun radiation effaiency whidr is observed by a oop is more applimble. Research aim was to examine crop density o{ radish with regard to radiation efficiency. Randomized block design was used with frve treatment of row spacing and three rcplbations. The treatments were 40 x 60 crn, 45 I 60 cm,50 x 60 cm, 55 x 60 cm and 60 x 60 cm each of which is repeated three times. Radiation on below crop shool radiailon on top crop shoot, air temperature, and rain fall vrere observed, The data were analyzed using ANOVA and least significance difference was used to test the significance differene among treatments. The result showed that radiation use efficiency of radish at various crop densities was 0.2333 - 0.3667 g MJ-1 and wide row spacing can cause decreasing of radiation use efficiency.
