EFFECT OF CROPPING SPACES ON RADISH

Abstract

Given the importance of culture and the need for phytotechnical knowledge about the spatial arrangement of plants. The objective of the present work was to evaluate the productive parameters of the radish culture when submitted to different spatial arrangements between plants and rows. For this, the hybrid cultivar Red Pearl was used as a test in a randomized block experimental design, arranged in a 4 x 6 factorial scheme, with four replications. The factors comprise the combination of crop spacing between “rows” and “plants”. The factor levels correspond to the distances between rows of: 8, 16, 24 and 32 cm; and plants of: 4, 6, 8, 10, 12 and 14 cm. Root yield, average root mass, longitudinal and transverse diameters and non-commercial roots were determined. The data were submitted to analysis of variance and, when significant, to linear regression analysis with the aid of Software R. The results showed that there is no interaction between the spacing factors for the analyzed parameters, and the spacing between rows and plants influences the independently evaluated attributes. Both treatment factors, when increased, provide less mass and greater root diameters.
