“…Several benefits are evidenced in systems that use crop variation in the same area, such as improved soil structure (SANTOS et al, 2000), greater economic stability of the system Soybean becomes a good ally for the floodplain production system. Goulart et al (2020) mention that the soybean crop was genetically adapted to well-drained environments, but originated from the flooded areas of northern China (EVANS, 1996).…”

It is known that soybean cultivation in recent years has shown a growing behavior in its use in succession with the production of irrigated rice in lowland areas. As a result, there are gaps both in the implementation of this succession and in its duration. Soy becomes an important ally to these production systems due to nutritional factors both for the environment (soil and weed control) and for the economic side of the property. Aiming to have an overview of the real situation of the properties in the physiographic region of the western border of Rio Grande do Sul, the present work proposes a research with the survey of general characteristics of the implantation and persistence of the succession systems of soybean with rice in lowlands, a since knowing the production deficiency gaps, you can have a better problem solving focus. A tester was developed and imposed on 10 properties that already have the system implemented. The questions involve since the beginning of the implantation, as well as the current progress of the system, correlating sowing, cultural and harvest management factors. With the results obtained, it was concluded that the gaps in the soybean-rice production system are in the phase of establishing crops and maintaining them, that is, in sowing and spraying, since the soybean harvest when detected with that of rice becomes easier due to its greater fluidity and lower depreciation of the machinery.

“…No período de 1988 a 1997, o rendimento mais elevado ocorreu no plantio direto (2.727 kg ha -1 ) e no cultivo mínimo (2.661 kg ha -1 ), em comparação com o de preparo convencional do solo com arado de discos (2.463 kg ha -1 ) ou com arado de aivecas (2.412 kg ha -1 ) (Tabela 3). Essas diferenças podem ser atribuídas à quantidade de palha remanescente, relatada anteriormente, e, como conseqüência, a deficiências hídricas em alguma fase crítica de desenvolvimento da cultura (Santos et al, 1999).

Práticas culturais e incidência 791Práticas culturais e incidência de manchas foliares em trigo (1) Ariano Moraes Prestes (2) , Henrique Pereira dos Santos (2) e Erlei Melo Reis (3) Resumo -Em experimento de campo, foram avaliados os efeitos de práticas culturais na incidência de manchas foliares, causadas por Drechslera tritici-repentis, Bipolaris sorokiniana e Stagonospora nodorum, e no rendimento de grãos de trigo. Foram comparados quatro sistemas de manejo de solo (plantio direto, cultivo mínimo, preparo convencional do solo com arado de discos + grade de discos e preparo convencional do solo com arado de aivecas + grade de discos) e três sistemas de rotação de culturas (trigo/soja; trigo/soja e ervilhaca/milho ou sorgo; e trigo/soja, aveia-preta ou aveia-branca/ soja e ervilhaca/milho ou sorgo). O delineamento experimental foi em blocos ao acaso, com parcelas subdivididas e três repetições. A parcela principal foi constituída pelos sistemas de manejo de solo, e as subparcelas, pelos sistemas de rotação de culturas. A incidência de manchas foliares de trigo foi mais elevada sob monocultura e sob plantio direto do que nos sistemas de rotação de culturas. A rotação de culturas viabilizou o plantio direto, em relação ao controle de manchas foliares, e garantiu a estabilidade do rendimento de grãos de trigo.Termos para indexação: manejo do solo, sistema de cultivo, doenças das plantas, grãos, rendimento. Effect of cultural practices on the incidence of leaf blotches of wheatAbstract -The effects of cultural practices on leaf blotches of wheat, caused by Drechslera tritici-repentis, Bipolaris sorokiniana and Stagonospora nodorum, and on grain yield were assessed in field experiments at Embrapa-CNPT, in Passo Fundo, RS, Brazil. Four soil management systems (no-tillage, minimum tillage, conventional tillage using a disk plow plus disk harrow, and tillage using a moldboard plow plus disk harrow) and three crop rotation systems [system I (wheat/soybean), system II (wheat/soybean and common vetch/corn or sorghum), and system III (wheat/soybean, black oats or white oats/soybean, and common vetch/corn or sorghum)] were compared. A randomized block experimental design, with split-plots and three replicates, was used. Leaf blotch incidence was higher under monoculture and no-till than under crop rotation. Crop rotation under no-tillage controlled leaf blotch diseases and maintained yield stability of wheat.

“…To help reverse the physical degradation process the soil goes through, as well as to prevent crops' productivity losses, several soil management practices are recommended, such as direct seeding system (DSS), green fertilization, intercropping, crop rotation, among others (Santos et al, 2008).…”

Soil physical properties and soybean productivity in succession to cover crops

et al. 2019

The objective of this research was to assess soybean productivity in succession to cover crops grown during the winter, in addition to assessing physical properties macroporosity (Ma), microporosity (Mi), total porosity (Pt), soil density (Sd) and aggregate stability by means of the following variables: aggregate stability index, geometric mean diameter and weighted mean diameter after soybean crop cultivation. The experiment was conducted in the municipality of Quatro Pontes, PR, using a randomized-block design with six treatments and four replications. Treatments consisted of soybean crop grown on top of different cover plants' haystack: black oat, black oat + forage turnip, forage turnip, black oat + forage pea, forage pea and control. Significant differences were observed for soil macroporosity and density. At the depth of 0.10 m, the highest Ma was observed in the area with oat and oat + turnip haystack. At other depths, all cover crops were superior to control. Treatments with cover crops were efficient in reducing soil PR. As for soil aggregation, the treatment with pea was superior to control for weighted mean diameter. The treatments with soybean sown after intercropping obtained greater mass, as well as higher productivity.
