SOME ASPECTS OF SEED SIZE AND PLANT SPACING ON THE MATURITY CHARACTERISTICS OF RADISH |

| Abstract:
A study was carried out to investigate the effect of plant density, plant arrangement, seed size and time of harvest on the weight frequency distribution of radish, and to explore ways of describing population variability. The coefficient of variation was found to be a useful means of describing population variability, as it measures variability independent of the size of the mean. Variability was found to increase with high density and high rectangularity, with a significant interaction between plant density and harvest date, with variability being independent of harvest date at low density, but increasing with time at high plant density. The development of positive skewness was enhanced by high rectangularities and high densities, but the effect of harvest date on skewness varied with the grade of seed used. | |
