“…Beyond the lack of available rainfall, the shading by the established rice crop may have reduced the photosynthetic rate of forage grass and, consequently, its dry matter yield. This intercrop response pattern was previously reported for U. ruziziensis and many other cash crops, such as sunflower (Souza et al, 2015), soybean (Erasmo et al, 2017), and maize (Ribeiro et al, 2018). These authors reported reduced forage yield due to shading.…”

Intercropping perennial forage grasses into cereal crops is an alternative to recover degraded pastures. However, the intercrop of forage grasses, such as Urochloa ruziziensis (R. Germ. and C. M. Evard) Crins (Congo grass), can lead to losses in cereal yield. Therefore, it is necessary to develop management strategies that allow forage grass establishment without major losses in cereal yield in intercropping. The objective was to study the agronomic and economic impacts of intercropping U. ruziziensis into a Clearfield upland rice (Oryza sativa L.) cultivar in the state of Goiás, Brazil, in two growing seasons. Treatments included forage grass seeds sowing method (broadcast or incorporation to the soil) and sowing times (at rice sowing, 20 days after emergence [DAE], and 45 DAE of rice). Also, imazapyr + imazapic herbicide was applied to restrict the competitive effect on rice yield. Monocropping control plots were also evaluated. Grain yield was measured on rice. Forage grass dry matter yield was measured at 30, 60, and 90 days after harvesting (DAH) of rice. Crude protein content was analyzed at 90 DAH. Profitability was calculated for each cropping system relative to rice monocropping. Intercropping of rice and U. ruziziensis sowed at 45 DAE provided the highest grain yield relative to other assessed intercropping treatments as well as rice monocropping. Concurrent sowing of rice and incorporated U. ruziziensis seeding provided the greatest economic return. This reformed cropping system improved land and pasture output, which can reduce the pressure to convert more land to agricultural use.

“…In the experimental conditions, there was no significant difference in the corn biomass (Table 3), indicating that the competition for water and nutrients among the brachiaria plants in the row did not influence the performance and yield of the corn plants. The biomass production of U. ruziziensis was higher in the single cultivation than brachiaria in intercropping systems (Ribeiro et al, 2018). In the intercropping conditions, in interspersed rows and/or in the same row, the brachiaria biomass production was higher than the U. ruziziensis sowing between the corn rows (Table 3).…”

The maize and Urochloa ruziziensis intercropping have potential use for agricultural production systems, allowing the production of grains and biomass. The study aims to evaluate the yield and economic viability of corn and U. ruziziensis intercropping modalities in the northwestern region of Paraná. The experiment was conducted in Maringá-PR in a completely randomized design with five treatments (single corn; single U. ruziziensis; U. ruziziensis between the corn rows; corn with U. ruziziensis in the same row; corn rows interspersed with U. ruziziensis rows) and four replicates. Initial development, grain yield of corn, and the production of biomass of corn and U. ruziziensis were evaluated. The data were submitted to analysis of variance. The means were compared by the Tukey test at 5% probability. In the initial development of corn plants, there was no significant difference due to intercropping. U. ruziziensis in the intercropped system had a reduction in biomass production. Intercropping with corn rows interspersed with U. ruziziensis rows had grain yield higher than other intercropping modalities and similar to single corn cultivation

“…O consórcio é uma técnica na qual mostra-se viável ao controle de plantas daninha, auxilia ainda, na conservação do solo e na adubação orgânica propiciando a recuperação deste (BARBOSA JUNIOR et al, 2019). Um exemplo de sistema consorciado é o cultivo de culturas como girassol e feijão comum, essas culturas , tiveram um melhor desenvolvimento quanto cultivadas isoladamente (RIBEIRO et al, 2018). Os agricultores de Canudos citaram que o cultivo em consórcio poupa espaço e diminui as prováveis perdas totais, algo de extrema importância para uma população carente de recursos financeiros.…”

A cadeia produtiva de biocombustíveis no Brasil tem gerado discussões no âmbito social, acerca de seus impactos para a agricultura familiar no Nordeste. Uma melhor eficiência agrícola para esta região poderia se dar a partir de matérias-primas mais adaptadas às condições locais. O cártamo é uma espécie oleaginosa resistente à seca e pouco exigente em nutrientes, com alto valor agregado, e que poderia se tornar uma alternativa para o desenvolvimento agrícola e econômico da região. Desta maneira, este trabalho objetivou caracterizar socioeconomicamente uma parcela dos agricultores familiares de um assentamento do município de Ceará-Mirim/RN e constatar o conhecimento deles acerca dos usos do cártamo e sua aceitação como cultura viável para a atividade agrícola visando à produção de biodiesel. A metodologia utilizada constou da aplicação de entrevistas a agricultores da agrovila Canudos. Os entrevistados são residentes da zona rural do município de Ceará-Mirim, sendo 68,1% mulheres e 31,81%, homens. Dos 22 representantes de cada família que foram entrevistados, a maioria da amostra (63,6%) é composta por pessoas de faixa etária entre 22 a 59 anos. As principais culturas cultivadas são: banana , macaxeira e feijão. Percebeu-se que os agricultores aceitariam o desafio da introdução do cártamo como cultura oleaginosa para a produção de biodiesel, apesar de desconhecerem a cultura.
