“…Still in the previous study, with this same experiment, from 1997/1998 to 2002/2003, the soybean grown after wheat (2,866 kg ha -1 ), in the system II, was superior to that grown after white oat (2,799 kg ha -1 ) and after wheat (2,804 kg ha -1 ), in the system III, and after wheat (2,636 kg ha -1 ), in the system I (Santos et al, 2006). The lowest values of grain yield, grain weight per soybean plant and 1,000-grain weight was observed in monoculture soybean.…”

The effects of crop rotation systems (CRS) on soybean yield and agronomic characteristics were evaluated from 1996/1997 to 2010/2011 at Embrapa Trigo, Passo Fundo (RS), Brazil. Four soil management systems (SMS) were compared, namely: 1) no tillage, 2) minimum tillage, 3) conventional tillage using a disk plow and a disk harrow, and 4) conventional using a moldboard and a disk harrow -and three CRS: system I (wheat/soybean), system II (wheat/soybean and common vetch/corn or sorghum) and system III (wheat/soybean, white oats/soybean and common vetch/corn or sorghum). This is a split-plot, randomized, complete block design with three replications. SMS were assigned in the main plot and CRS systems in the split-plots. This work addressed only data on crop rotation systems. There were no significant differences between the CRS for number of grains per plant, 1,000 grain weight and first pod height in soybean. The crop rotation for a summer, with corn or sorghum, propitiates a higher soybean yield compared with the other systems and monoculture soybean. The combination of conservation systems (no tillage and minimum tillage) and CR resulted in a higher soybean yield. The lowest grain yield and grain weight per plant were obtained in monoculture soybean.

“…This demonstrates the importance of notillage in increasing soybean tolerance to hydric stresses (FRANCHINI et al, 2009), increasing the bond number and strength of soil aggregates by age-hardening phenomena (MORAES et al, 2017), improving soil aggregation and its structure that allows greater storage of available water (SILVA et al, 2014), upward flow of water from the deeper layers to the more superficial layers of water (MORAES et al, 2016) and increased rooting depth (MORAES, 2017). Santos et al (2006) observed that, independently of crop rotation systems, soybean cultivated under no-tillage showed higher grain yields, a greater mass of 1,000 grains, with higher plant height than soybean cultivated under conventional tillage system, with disk plow or turning plow.…”

“…These authors observed a 17% increase in the average yield of soybean, under rotation system with maize, in relation to that observed in the succession with wheat. Santos et al (2006) reported that the higher grain yields in crop rotation systems relative to the wheat / soybean succession model were related, in part, to the final population of plants, the grain mass per plant, the mass of thousand grains and the height of soybean plants.…”

-No-tillage system have been a mainly conservationist system specially in tropical and subtropical climate conditions. The aim of this work was to evaluate yield components and morphological soybean and wheat in Rhodic Eutrudox under tillage and cropping systems in Subtropical climate (Londrina, Brazil, latitude 23º11'S; longitude 51º11'W; and 620 m in altitude). This study was carried with five tillage and two cropping systems, on completely randomized block design, with four replications. Tillage systems consisted of conventional tillage with disk harrow; minimum tillage with annual chiselling; minimum tillage with chiselling every three years; no-tillage for 11 years; and no-tillage for 24 years. The factor cropping systems was represented by crop rotation and crop succession. In the soybean crop were evaluated yield, mass of 1000 grains, plant height, and first pod insertion of soybean, chlorophyll content and the vegetation index normalized difference. Furthermore, for the wheat cropping was evaluated the grain yield and hectolitre weight. Soybean and wheat grain yields were not changed due to cropping systems. Soybeans yield in no-tillage with 24 years was higher than in conventional tillage; and soybean and wheat yields were not affected by times under no-till adoption. Soil chiselling not favoured increased in productivity of soybean and wheat. Thus, soil chiselling under this climate conditions is an unnecessary practice due to absence of productive and morphological improvement for soybean and wheat cropping.Keyword: no-tillage system; long-term experiment; Glycine max; Triticum aestivum.Resumo -O sistema plantio direto tem sido um dos principais sistemas conservacionistas dos solos em regiões tropicais e subtropicais. O objetivo deste trabalho foi avaliar parâmetros de rendimento e morfológicos de soja e de trigo em Latossolo Vermelho sob sistemas de manejo e modelos de produção em região de clima Subtropical (Londrina, Brasil, latitude 23º11'S; longitude 51º11'W; e 620 m de altitude). O delineamento de blocos ao acaso foi usado, em esquema fatorial, com cinco preparos, dois modelos de produção e quatro repetições. Os preparos do solo incluíram o convencional; mínimo escarificado anualmente ou a cada três anos; sistema plantio direto com 11 anos; e sistema plantio direto com 24 anos. O fator sistema de cultivo foi comporto por rotação e sucessão de culturas. Na cultura de soja foi avaliada a produtividade de grãos, massa de mil grãos, altura de plantas e de inserção do primeiro legume, teores de clorofila e índice de vegetação por diferença normalizada, já na cultura de trigo foram avaliadas a produtividade e o pH dos grãos. As produtividades de grãos de soja e de trigo não foram alteradas em função dos modelos de produção. Entre os tempos de adoção do sistema plantio direto não houve diferenças de produção de grãos, sendo maior do que no preparo convencional. A escarificação do solo não incrementou a produtividade de grãos das culturas. Assim, a escarificação do solo sob as condições edafocl...

“…foi determinada por meio da percentagem de plantas que apresentaram o sintoma no total de 20 plantas por parcela, no estádio fenológico R6 da soja, tendose observado o sintoma na área foliar, conhecido como folha carijó, que é caracterizado por manchas cloróticas e necróticas internervais, com coloração verde normal, na região das nervuras, e com coloração castanho-claro a castanho-avermelhado escuro, na raiz (Almeida et al, 2005 (Kluthcouski et al, 2000). Já Santos et al (2006b) verificaram que, independentemente de rotação, a soja cultivada sob plantio direto e sob cultivo mínimo apresenta maior produtividade, maior massa de mil grãos e maior altura de plantas, em comparação à soja cultivada sob preparo convencional de solo.

Resumo -O objetivo deste trabalho foi avaliar o efeito dos sistemas de manejo do solo e de coberturas de inverno sobre o número de propágulos de Fusarium spp. no solo, a incidência da podridão-vermelha-da-raiz (PVR) e a produtividade das cultivares de soja CD 206 e FT Fênix. Sudden death syndrome of soybean under different soil management systems and cover cropsAbstract -The objective of this work was to assess the effect of soil management systems and winter cover crops on the number of propagules of Fusarium spp. in soil, the incidence of sudden death syndrome ( However, in the second year, this difference was not observed. The soil management systems and winter cover crops used do not influence the incidence of SDS in soybean cultivars or the number of Fusarium spp. propagules in soil. The plowed system provides an increase in soybean yield in the second year of management.
