Resumo
A adoção do consórcio de milho com plantas de cobertura aliado a
tecnologia de inoculação com Azospirillum brasilense pode proporcionar
melhorias positivas nos atributos do solo, no controle da erosão hídrica, além
do aporte de resíduos culturais deixados na sua superfície, bem como
desempenho produtivo de culturas comerciais em sucessão. Assim, o objetivo
desta pesquisa foi avaliar o efeito residual de sistemas de consórcios de milho
com plantas de cobertura e inoculação via foliar com Azospirillum brasilense,
no crescimento e produtividade do feijoeiro irrigado por aspersão. O
delineamento experimental foi em blocos casualizados disposto em esquema
fatorial 4x2 para o feijão, com quatro repetições. Os tratamentos foram
constituídos pelos cultivos antecessores de milho solteiro e consorciados com
culturas de cobertura (Crotalaria spectabilis, Urochloa ruziziensise, C.
spectabilis + U. ruziziensis) na presença e ausência da aplicação via foliar (no
estádio fenológico V4) do inoculante contendo Azospirillum brasilense, com
quatro repetições. Foram avaliadas na cultura do feijão: população de plantas,
matéria seca de plantas, concentração foliar de nitrogênio, número de vagens
por planta, número de grãos por planta, número médio de grãos por vagem,
massa de cem grãos, produtividade de grãos e ciclo. Na análise estatística das
variáveis avaliadas os dados foram submetidos à avaliação dos pressupostos
estatísticos e a análise de variância. Para verificar os efeitos isolados e da
interação entre os fatores as médias foram comparadas pelo teste de Tukey,
adotando-se nível de 5% de significância (p<0,05). O uso de inoculante no
feijoeiro em sucessão a sistemas de consórcio de milho com plantas de
cobertura pode causar efeitos residuais positivos na cultura.
The adoption of the brazil technology consortium with protection corn allied to inoculation plants can provide adjustments with special attributes, without control of brazil photometry, in addition to cultural protection support for individual solutions on its surface, as well as productive performance of crops acquired in succession. Thus, the objective of this research was to evaluate the residual effect of corn intercropping systems with cover crops and inoculation via foliar with Azospirillum brasilense, on the growth and productivity of bean irrigated by persion. The experimental design was randomized in a 4x2 factorial scheme for beans, with four replications in blocks. The treatments consisted of single corn predecessor crops and intercropped with cover crops (Crotalaria spectabilis, Urochloa ruziziensise, C. spectabilis + U. ruziziensis) in the presence and absence of foliar application (at phenetic stage V4) of the inoculant with Azospirillum brasilense , with four. : plant varieties of medium grain plants in the dry bean crop, plant content of medium-grain plants of active grains, number of average plant masses, plant grains, number of average-grain plants per pod, grain yield and cycle . In the analysis of the evaluations of the evaluations of the data, the configurations of the statistical data and the analysis of variables were included. For the control and analysis factors of selected tests, they were significantly approved by the Tukey test (p<0.05). The use of inoculant in common bean in succession to corn intercropping systems with cover crops can cause positive residual effects on the crop, which can result in a decrease in economic costs.
