Desempenho agronômico da soja cultivada em diferentes épocas e distribuição de plantas

Abstract: RESUMOPeríodos favoráveis à semeadura bem como a disposição espacial em que plantas se encontram na área de cultivo são fatores que influenciam diretamente a produtividade da soja. A melhor equidistância entre plantas para determinada época de cultivo pode resultar em maior aproveitamento de água, luz e nutrientes. Nesse contexto, por duas safras agrícolas de verão contínuas, foram realizados experimentos de campo com o objetivo de avaliar o desempenho agronômico da soja semeada em diferentes épocas e distribu… Show more

“…For this to happen, developing implements that allow the use of this technology to be feasible are necessary. Similar results were observed in soybean cultures, in which higher yield was observed in densified sowing when compared to traditional spacing (Moreira, Moraes, Schroth, & Mandarino, 2015;Carmo, Braz, Simon, Silva, & Rocha., 2018), although Balbinot, Procópio, Debiasi, Franchini and Panison (2015) observed greater yield using 0.6 m spacing when compared to 0.4 m in soybean cultivars of determined growth. With these findings, the possibility of a new alternative of management practice in the soybean/corn season production system opens up, increasing farmers' cultivation alternatives and consequently, the possibility of more profitable crops.…”

“…When evaluating soybean, Zardo and Casimiro (2016) reported 25.4% of flawed and 23.3% of double spacing, and these percentages were similar to those in the current study. Some authors have noted that the arrangement of soybean plants affects their productivity and is related to the adaptability of plants to the available space (Carmo et al, 2018). Notably, the period during which crops in integrated systems are killed may affect the sowing uniformity and agronomic performance of soybean in succession (Franchini et al, 2015) because of the moisture of the biomass present on the soil at the time of planting, which may increase the risk of wheel slip by machinery during sowing and contribute to clogging of the machine with uncut biomass that in turn accumulates in the path of the seeder (Aratani et al, 2009).…”

“…Destaca-se a baixa produtividade das cultivares na época 4 (20/11/2012), sendo que esta época em ambos os locais e cultivares (exceto para a cultivar TMG 1179 em Tangará) obtiveram a menor produtividade. Isso se deve ao fato de que a época de cultivo ter efeito sobre as características morfológicas e componentes do rendimento de plantas de soja, ou seja, o retardamento da época de semeadura proporciona menores rendimentos de grãos (CARMO et al, 2018).…”
