Determinação de épocas de semeadura de genótipos de soja adaptados a solos cultivados em rotação com arroz irrigado no município de Manoel Viana e Alegrete/RS

Abstract

Determination of sowing time and soybean genotype of adapted to soils in crop rotation with irrigated rice in the municipalyts of Manoel Viana/RS and Alegrete/RS. This work aimed to identify the best sowing season and which genotypes are adapted to the edaphoclimatic conditions of the Manoel Viana and Alegrete / RS regions. The sowing will be carried out in three different seasons, where each sowing will consist of three plots. These varieties were selected because they represent different groups of relative maturity and type of growth. the reproductive stages of the soybean plant - R1, R3, R5, R7 and after stage R8 will be identified, the height of the first legume of the plant will be identified; Degree of accommodation (1 = standing plants 5 = lying plants); Number of plants in three linear meters; Number of nodes (Count of the number of nodes of the unifoliolated leaves node); Number of fertile nodes; Number of plants per plant; Number of grains in 100 vegetables; Weight of 1000 grains; Productivity; Allow the producer to identify the most appropriate maturity groups at each growing season in the western border region, providing more accurate information about the region. According to the statistics, for the 3 sowing times with irrigation and without irrigation, they did not have any significant difference.
