“…Mesmo assim, estes resultados mostram a importância do consórcio com leguminosas, principalmente na adição de proteína à forragem de gramíneas, melhorando seu valor nutritivo aliado à diminuição de custos e aumento da sustentabilidade do sistema produtivo (Oliveira, 1989;Sood & Sharma, 1992;Silva et al, 2000;Silva et al, 2003;Silva et al, 2004;Obalum & Obi, 2010;Alcantara et al, 2011).…”

O consórcio de plantas forrageiras visa ao aumento da produtividade e qualidade dos produtos obtidos com maior eficiência de uso dos recursos disponíveis. O objetivo do trabalho foi avaliar o rendimento forrageiro da rebrota do sorgo em função das épocas de semeadura, cultivares de soja e sistemas de corte com a soja consorciada na entrelinha. O experimento foi conduzido na Universidade Federal de Lavras em um Latossolo Distroférrico, durante dois anos agrícolas (2006/07 e 2007/08). Utilizou-se o delineamento de blocos casualizados em esquema fatorial 5x3x3+5, compreendendo cinco épocas de semeadura do sorgo, híbrido Volumax, (30/10, 15 e 30/11 e 15 e 30/12), três cultivares de soja (Monsoy 8400, Conquista e Luziânia) e três sistemas de corte (1-corte rente ao solo; 2 -15 cm acima do solo; 3 -30 cm acima do solo). Os tratamentos adicionais foram constituídos pelo monocultivo do sorgo avaliando-se as cinco épocas de semeadura. Na rebrota do sorgo observaram-se aumentos para massa verde e proteína bruta em função das épocas de semeadura e sistemas de corte. O sistema de corte 3 proporcionou os maiores rendimentos de massa verde (5.516 kg ha -1 ), massa seca (2.395 kg ha -1 ) e proteína bruta (173 kg ha -1 ). O sistema consorciado apresenta maiores rendimentos de massa seca e proteína bruta.

This study aimed to evaluate the effects of sorghum sowing dates, soybean cultivars and cutting systems on forage production from the regrowth of an intercropping system using sorghum and soybean crops. The experiment was carried out at the University of Lavras in a typical distroferric latosol, in two crop years (2006/2007 and 2007/2008). The experiment was conducted in a randomized block design with a 5x3x3+5 factorial scheme, corresponding to five sorghum sowing dates (10/30; 11/15; 11/30; 12/ 15 and 12/30), using the hybrid "Volumax", three soybean cultivars (Monsoy 8400, Conquista and Luziânia) and three cutting systems (1 -cut at ground level; 2-15 cm above ground; 3-30 cm above ground). Additional treatments were composed by the monoculture of sorghum, in which the five sowing dates were analyzed. In the sorghum regrowth, the sowing dates and cutting systems significantly increased the green matter and crude protein levels. Cutting system 3 provided the highest green matter (5,516 kg ha -1 ), dry matter (2,395 kg ha -1 ), and crude protein yields (173 kg ha -1 ). The intercropping system provides the highest dry matter and crude protein yields.

The objective of this work was to evaluate the yield and physiological quality of seeds of different bean genotypes produced in the off-season period in the subtropical region of Rio Grande do Sul state. The work was divided in two experiments. The first one evaluated the number of pods per plant, number of seeds per plant, number of seeds per pod, thousand seed weight and seed yield per plant of five bean genotypes (IPR Tuiuiú, BRS Embaixador, Guabiju, Carioquinha and Mouro ), during 2013 and 2014 offseason periods. In the second study, the physiological quality of the seeds such as germination, first germination count, shoot and root dry matter were measured under different osmotic potentials (0.0, -0.09, -0.18, and -0,27 MPa) at temperatures of 25 and 35°C. Moreover, the isoenzymatic expression of the seedlings at the temperatures 25 and 35°C, of the seeds from the 2013 crop was evaluated. The results showed that IPR Tuiuiú and Carioca genotypes have superiority in yield components, whereas the BRS Embaixador showed the highest Thousand seed weight. The physiological quality of the seeds was reduced in the lower osmotic potentials at both temperatures. The expression and intensity of isoenzyme peroxidase bands were higher in potencies of -0.09 and -0.18 MPa for all genotypes at both temperatures.

“…Common bean is sensitive to environmental changes during flowering (Didon and Silva, 2004) and may cause flower abortion and drop of pods (Silva et al, 2006). According to Stülp et al (2009) and Alcantara et al (2011), sowing outside the appropriate time can cause a reduction of 50% in SY of soybeans and change the chemical composition of the produced grains.…”
