Desempenho de cultivares de soja submetidas à semeadura agrupada e convencional

Abstract

Due to the economic importance of soybean, innovations in spacing and distribution of plants in the sowing line are being studied in order to increase the yield of this crop. In this way, the objective of this work was to evaluate the agronomic performance of soybean cultivars submitted to grouped and conventional sowing. The experiment was installed in the experimental field of the Federal Technological University of Paraná, Campus Dois Vizinhos. The experimental design was a randomized block design, with three replications, in a 2 x 4 factorial scheme. The first factor was composed by the different sowing methods (conventional and clustered) and the second by soybean cultivars of contrasting cycles. following treatments: T1: Cultivate 5D634 conventional sowing; T2: Cultivate 5D634 grouped sowing; T3: Cultivation TMG7062IPRO conventional sowing; T4: Cultivate TMG7062IPRO grouped sowing; T5: Cultivation LG60163RR conventional sowing; T6: Cultivate LG60163RR grouped sowing; T7: Cultivate conventional NS6006IPRO sowing; and, T8: Cultivate NS6006IPRO grouped sowing. It was evaluated the height of plants, height of insertion of the first pod, number of pods per plant, number of grains per plant, number of grains per pod, mass of one thousand grains and crop productivity. The height of plants and height of insertion of the first pod were influenced by the arrangement of plants and cultivars studied. The mass of a thousand grains varied according to the types of soybean cultivars. The planting arrangements did not influence the mass of a thousand grains and the yields of the soybean cultivars.
