O crescimento da cultura da soja no país esteve sempre associado aos avanços científicos e à disponibilização de tecnologias ao setor produtivo. Assim, o trabalho objetivou avaliar as características agronômicas e a produtividade da soja semeadas em sucessão ao sistema de Integração lavoura-pecuária com forrageiras consorciadas com o milho, com ou sem a inoculação da semente com Azospirillum brasilense. A pesquisa foi desenvolvida em área de sequeiro no Núcleo de Ensino, Pesquisa e Extensão do Unifunec. O delineamento experimental foi o de blocos casualizados, em esquema fatorial 4 x 2, com quatro repetições, sendo que a soja foi semeada nos tratamentos em um ciclo completo de integração lavoura-pecuária, assim os tratamentos foram compostos pelas áreas com 4 variedades de forrageiras (MG-13 Braúna; Marandú; Mombaça e Tanzânia) consorciadas com milho, com ou sem inoculação das sementes com bactéria Azospirillum brasilense. A soja foi semeada mecanicamente no início de dezembro, utilizando-se a cultivar TMG 2165 IPRO. Foram avaliados os componentes da produção e produtividade da soja. A inoculação com A. brasilense na cultura do capim e milho antecessor à soja incrementou os componentes de produção e produtividade da soja em sucessão. Houve desdobramento da interação da forrageira dentro da modalidade de inoculação para a produtividade de soja, evidenciando um aumento quando inoculado. Com efeito da palhada dos capins e, principalmente quando do uso da bactéria fixadora antecessor à soja, houve incrementos nas características agronômicas e produtividade da soja.   COMPONENTS OF SOYBEAN PRODUCTION CULTIVATED IN DRYLAND IN THE INTEGRATED CROP-LIVESTOCK SYSTEMS USING AZOSPIRILLUM BRASILENSE   ABSTRACT The increase in soybean cultivation in the country has always been associated with scientific advances and the availability of technologies to the productive sector. Accordingly, this study aimed to evaluate the agronomic characteristics and productivity of soybeans sown in a successional crop-livestock integration system with forage crops intercropped with corn, with or without inoculation of the seed with Azospirillum brasilense. The research was developed in a dryland area in the Teaching Research and Extension Center of Unifunec. The experimental design was in randomized blocks, in a 4 x 2 factorial scheme, with four repetitions, and soybeans were sown in the treatments in a complete cycle of crop-livestock integration, so the treatments were composed of areas with four varieties of forage (MG-13 Brauna, Marandu, Mombasa and Tanzania) intercropped with corn, with or without inoculation of the seeds with Azospirillum brasilense bacteria. Soybeans were mechanically sown in early December, using the TMG 2165 IPRO cultivar. The production and yield components of soybean were evaluated. The inoculation with A. brasilense in the culture of grass and corn before soybean increased the components of production and productivity of soybean in succession. The interaction of forage within inoculation modality was unfolded for soybean yield, showing an increase when inoculated. With the effect of the grass stubble and especially when using the fixing bacteria before soybeans, there were increases in agronomic characteristics and productivity of soybeans.   Keywords: Urochloabrizantha; Megathyrsus maximum; Crop-livestock integration; Glycine max (L.)

Water Use Efficiencies

Introducing alternative cultivars with enhanced water use efficiencies can help alleviate pressure on groundwater for crop irrigations in Mississippi (MS) Delta. A two-year field study was conducted in 2019–2020 to compare the water use efficiencies (WUE) of recently released and pre-released soybean {Glycine max (L.) Merr.} cultivars in maturity group (MG) III (‘P37A78’, ‘LG03-4561-14’), IV (‘Dyna-gro 4516x’, ‘DS25-1, DT97-4290’), and V (‘S12-1362’, ‘S14-16306’) in the MS Delta. The experimental design was a split-plot with cultivar as the first factor and the second factor was water variant irrigation (IR) and no irrigation (RF, rainfed), replicated three times. The MG IV cultivar Dyna-gro 4516x recorded the highest grain yield and WUE: grain yields were 4.58 Mg ha−1 and 3.89 Mg ha−1 under IR and RF, respectively in 2019, and 4.74 Mg ha−1 and 4.35 Mg ha−1 in 2020. The WUE were 7.2 and 6.9 kg ha−1 mm−1, respectively, in 2019 under IR and RF, and 13.4 and 16.9 kg ha−1 mm−1 in 2020. The data reveals that ‘Dyna-gro 4516x’ (MG IV), ‘LG03-4561-14’ (MG III), and ‘P37A78’ (MG III) are best adapted to the early soybean production system (ESPS) in MS Delta region for sustainable production for conserving water resources.

Abstract Soybean (Glycine max L.) is annual crop that have high morphologies and yield components diversity. The research was conducted at the first season of 2011, the objective of the research were to find morphological, yield, and yield component of Soybean germplasm (Glicine max L.). The research was carried out at experimental station BB-BIOGEN Citayam, Depok, and laboratory of Gene Bank BB-BIOGEN. The experiment used randomized block design with 100 different accessions and three replications for each accession. Based on the observation, the morphological characters have many visual forms. They are as follows: growth percentage in which 19.33 – 99%; growth types were determinate and indeterminate, the leave form was triangle to sharp; purple and white flowers; yellow and black seeds color. The range of values for each characteristic component are as follows: plant height 29,23 – 104,25 cm; number of pods per plant was 23,6 – 99,82; flowering time 33 – 47 days after planting; 100 seed weight 5,98 – 20,77 gram; maturing time 75 – 96,67 days after planting; root nodule’s weight 0,004 – 0,109 gram; seed’s weight 3,15 – 11,45 gram/plant. Among the accessions, the highest yield was shown by B 4323 (643,27 gram/3,6 m2). Significant correlation was shown between soybean’s yield components and yield which were plant’s height, growth percentage, numbers of main stem’s node, numbers of pods, seeds weight for each plant and root nodule’s weight. 100 seeds weight showed significant negative correlation with soybean components.   Key words: germplasm, morphological characteristics, soybean, yield components

Trail System

The soybean crop (Glycine max. (L.) Merril) shows strong participation in the Brazilian economy. Therefore, the aim of the present study was to quantify the losses in the cutting and feeding platform and in the trail system in mechanized soybean harvest by analyzing different speed and rotation adjustments of the trailing cylinder. The experiment was carried out in a commercial soybean plot on a farm located in the municipality of Brejo (MA), during the 2017/2018 harvest. The harvester evaluated was a Case IH 8120, with a maximum power of 34.2 kW, axial flow system, and 12.2-m platform equipped with a conveyor system (draper). The experiment was conducted in two different areas. Area 1 was planted with the Brasmax® Opus (BMX Opus) cultivar, while area 2 was cultivated with the BRS 9383 cultivar. The treatments consisted of three machine speeds (4 km h-¹, 6 km h-¹, and 7 km h-¹), associated with the rotation levels of 500 rpm and 800 rpm in the trail system. The experimental design used was randomized blocks in a 3 x 2 factorial arrangement, with four replications. For the BMX Opus cultivar, harvest losses did not influence the travel speeds and rotations evaluated in the experiment due to the marked instability within the treatments. The BRS 9383 cultivar showed satisfactory results at a speed of 4 km h-1 combined with a rotation of 800 rpm, which obtained acceptable numbers for the soybean harvest (54.09 kg ha-1).
