Resumo
O presente trabalho teve por objetivo avaliar o desempenho de leguminosas como adubação verde visando melhorar a aeração, o teor de matéria orgânica e contribuir com a fertilidade do solo. O projeto foi instalado no Instituto Federal de Educação Ciência e Tecnologia-Campus Muzambinho, no mês de novembro do ano de 2008. Para a realiza- ção do experimento utilizou-se uma área cultivada com a variedade Rubi MG 1192, com idade de 12 anos, dispostas no espaçamento 0,8 m entre plantas e 4,0 entre linhas. O delineamento experimental utilizado é o de blocos ao acaso, com 4 repetições e de 5 tratamentos perfazendo um total de 25 parcelas. Cada parcela é constituída de 10m. Cada parcela possui uma bordadura separando-as entre si. Os tratamentos são constituídos por quatro leguminosas e uma testemunha, sendo elas: soja, crotalária, mucuna preta e guandú. As leguminosas foram plantadas nas ruas do cafeeiro, com três linhas de 10m de comprimento, contendo dezessete plantas por metro linear. As leguminosas foram roçadas no início do florescimento e permaneceram em decomposição na superfície do solo. As testemunhas foram roçadas quando as plan- tas invasoras alcaçaram em média 0,70m. Após 60 dias foram coletadas amostras de solos e encaminhadas ao Labora- tório de Análise de Solos Instituto Federal de Educação Ciência e Tecnologia-Campus Muzambinho. Para avaliação do experimento foram considerados as seguintes variáveis: Fertilidade do solo, monitorada por análise das amostras, le- vando em consideração pH, CTC, teor de matéria orgânica macro e micronutrientes. Os resultados da análise química de solos obtidos no presente trabalho foram submetidos à análise de variância, utilizando-se o software SISVAR, sendo utilizado o teste de médias Scott-Knott. De acordo com os dados obtidos no presente trabalho conclui-se que: O solo cultivado com leguminosas apresenta menor acidez e elevação da soma de bases e da capacidade de troca de cátions (CTC) quando comparado com a testemunha (indicadores de fertilidade do solo). As leguminosas utilizadas como adu- bo verde mucuna e guandu aumentam significativamente os teores de cálcio, ferro, cobre e boro e o adubo verde guandu é responsável pelo maior teor de zinco e manganês no solo.
This study aimed to evaluate the performance of legumes as green manure to improve the aeration, organic matter content and contribute to soil fertility. The project was installed at the Instituto Federal de Educação Ciência e Tecnologia-Campus Muzambinho, in November of 2008. To perform the experiment we used an acreage with a variety Rubi MG 1192, aged 12 years, arranged in 0.8 m spacing between plants and 4.0 between lines. The experimental design is randomized complete block with four replications and five treatments for a total of 25 plots. Each plot consists of 10m. Each plot has a border separating them from each other. The treatments consist of four legumes and a witness, as follows: soybean, sun hemp, pigeon pea and velvet bean. The legumes were planted in the streets of coffee with three rows of 10m in length, with seventeen plants per meter. Legumes were mowed at flowering and remained in decomposition at the soil surface. The witnesses were the weeds when mowed proved unexpectedly strong on average 0.70 m. After 60 days soil samples were collected and sent to the laboratory of the Instituto Federal de Educação Ciência e Tecnologia-Campus Muzambinho. For evaluation of the experiment were considered the following variables: Soil Fertility, monitored by analysis of samples, taking into account pH, CTC, organic matter content of macro and micronutrients. The results of chemical analysis of soils obtained in this study were subjected to analysis of variance, using the software SISVAR, by using the mean test Scott-Knott. According to data obtained in this study concluded that: The soil under legumes has lower acidity and raising the sum of bases and cation exchange capacity (CTC) when compared with control (indicators of soil fertility) . The legumes used as green manure, mucuna and pigeonpea increased significantly, calcium, iron, copper and boron and pigeon pea green manure is responsible for higher levels of zinc and manganese in the soil.
