Desempenho agronômico do rabaneteiro em diferentes arranjos de cultivos

Abstract

The radish is a short-cycle vegetable that allows fast financial return to the farmer, the small size allows its insertion in the lines of cultivation (consortium). However, in order for good yields and final product quality to be achieved, research should be developed as the evaluation of the arrangement of plants in the crop. Based on the above, this work aimed to evaluate the agronomic performance of the radisher at different plant densities under conditions in Fortaleza-CE. The experimental design was a randomized complete block design in a 4x2 factorial scheme, with two plant numbers per cultivation pit (one and two plants) combined with four plant spacings (0.05, 0.10, 0.15 and 0 , 20 m). Three replicates of each treatment were conducted, with 10 plants per treatment being evaluated. The number of leaves, fresh and dry mass of shoot and tuber, length and diameter of tuber, percentage of tuberous plants, firmness of tubers, percentage of surviving plants and commercial productivity were evaluated. The density of one plant per pit combined with the spacings of 0.05 and 0.10 m between plants obtained higher values of fresh and dry mass of the tufa, length and diameter of the tuber and greater percentage of tuberization. The highest productivity was observed for the spacing of 0.05 m between growing line combined with density of one plant per pit. From the results obtained, it is concluded that the spacing of 0.05 m between plants combined with only one plant per pit is the most indicated for higher yield and good quality of the radish in the edaphoclimatic conditions of Fortaleza-CE.
