Resumo: | Soybean (Glycine max (L.) Merrill) is the leading culture of Brazilian agriculture. With today's global economy, there is greater demand of increased grain yield by adopting appropriate management practices, in which is detached the plant arrangement. These practices aim to maximize the use of environmental factors, not raise production costs and provide greater compet itiveness. In this sense, it is aimed to evaluate the growth characteristics and yield of soybean grain depending on the form of seeding and density of the plants. Two experiments were conducted in the growing season of 2013/2014 and 2014/15, with BMX Ativa RR cultivars (determined growth) and BMX Alvo RR (indeterminate growth) seeded at a spacing of 45 cm between rows and cross-seeding in five plant density (180, 240, 300, 360, 420,000 plants ha-1). It was evaluated the plant height, leaf area index, percentage of soil coverage, the first pod height, number of pods per square meter, number of grains per pod. Weight of one thousand of grains and grain yield. The overall result obtained showed higher plant height in the V6 stage in cross -seeding in two years. In Year 1, cultivate BMX Ativa had the highest plant height in V6 and R2 stages. The increase in plant density increases the height of plants in Year 1 in the V6 stage and two years at R2 stage. The leaf area index was higher in the cross-seeding in both years. Cultivar BMX Alvo RR showed higher IAF regarding BMX Ativa RR, and the increasing of plant density increased IAF. The percentage of ground cover index was higher in the cross-seeding, and as a result of increased plant density. The height of insertion of the first pod was smaller in crossseeding, cultivating BMX Alvo RR had a greater insertion of the first pod in relation to BMX Ativa RR and increasing plant density raised the height of insertion of the first pod. The number of pod per square meter, it was higher in Year 1 , it was higher in cross-seeding, and in Year 2 was higher in the planting spacing of 45 cm. Cultivar BMX Ativa RR showed higher number of pods per square meter and the increased density increased the number of pods per square meter. The number of seeds per pod was higher in cross-seeding and growth of density increased the number of seeds per pod. The weight of a thousand grains in Year 1 was higher in cross-seeding, and in Year 2 was higher in the planting spacing of 45 cm. In both years the PMG was higher in growing BMX Alvo RR. The grain yield was higher in the cross-seeding, and growth of plant density increased grain yield. |

Com a atual economia globalizada, há maior exigência do aumento do rendimento de grãos, pela adoção de práticas de manejo adequadas, na qual se destaca o arranjo de plantas. Essas práticas visam maximizar o uso dos fatores ambientais, não elevar os custos de produção e proporcionar maior competitividade. Neste sentido, objetivou-se avaliar as características de crescimento e rendimento de grãos de cultivares de soja em função das formas de semeadura e densidade de plantas. Foram conduzidos dois experimentos nos anos agrícolas de 2013/2014 e 2014/15, com as cultivares BMX Ativa RR (crescimento determinado) e BMX Alvo RR (crescimento indeterminado) semeadas no espaçamento de 45 cm entre fileiras e em semeadura cruzada, em cinco densidades de plantas (180, 240, 300, 360, 420 mil plantas ha-1). Avaliou-se a altura de plantas, o índice de área foliar, percentagem de cobertura do solo, altura de inserção da primeira vagem, número de vagens por metro quadrado, número de grãos por vagem, peso de mil grãos e rendimento de grãos. Os resultados obtidos, indicaram maior altura de plantas no estádio V6 na semeadura cruzada nos dois anos. No Ano 1 a cultivar BMX Ativa teve a maior altura de planta, nos estádios V6 e R2. O aumento da densidade de plantas elevou a altura de plantas no Ano 1 no estádio V6 e nos dois anos no estádio R2. O índice de área foliar foi maior na semeadura cruzada em ambos os anos. A cultivar BMX Alvo RR apresentou maior IAF em relação a BMX Ativa RR, e o aumento da densiade de plantas elevou o IAF. A percentagem de cobertura do solo foi maior na semeadura cruzada, e em com o aumento da densidade de plantas. A altura de inserçao da primeira vagem foi menor na semeadura cruzada, a cultivar BMX Alvo RR teve uma maior inserção de primeira vagem em relação a BMX Ativa RR e o aumento da densidade de plantas elevou a altura de inserção da primeira vagem. O número de vagens por metro quadrado foi maior no Ano 1 foi maior na semeadura cruzada, e no ano 2 foi maior na semeadura com espaçamento de 45 cm. A cultivar BMX Ativa RR apresentou maior número de vagens por metro quadrado e o aumento da densidade elevou o número de vagens por metro quadrado. O número de grãos por vagem foi maior na semeadura cruzada e o aumento da densidade diminuiu o número de grãos por vagem. O peso de mil grãos no Ano 1 foi maior na semeadura cruzada, e no Ano 2 foi maior na semeadura com espaçamento de 45 cm. Em ambos os anos o PMG foi maior na cultivar BMX Alvo RR. O rendimento de grãos foi maior na semeadura cruzada, e o aumento da densidade de plantas elevou o rendimento de grãos.Submitted by Aline Rezende (alinerezende@upf.br) on 2018-05-11T17:05:56Z No. of bitstreams: 1 2016EmanuelFontana.pdf: 368981 bytes, checksum: de08974007ed639d48283149afe8236d (MD5)Made available in DSpace on 2018-05-11T17:05:56Z (GMT).

Weight of one thousand of grains and grain yield. The overall result obtained showed higher plant height in the V6 stage in cross -seeding in two years. In Year 1, cultivate BMX Ativa had the highest plant height in V6 and R2 stages. The increase in plant density increases the height of plants in Year 1 in the V6 stage and two years at R2 stage.

The percentage of ground cover index was higher in the cross-seeding, and as a result of increased plant density. The height of insertion of the first pod was smaller in crossseeding, cultivating BMX Alvo RR had a greater insertion of the first pod in relation to BMX Ativa RR and increasing plant density raised the height of insertion of the first pod.
