Crescimento e produção de coentro irrigado no semiárido com uso de bagana de carnaúba como cobertura vegetal

Abstract

Carnauba has economic, social and environmental importance in the semi-arid. It occupies several workers in the countryside and contributes to poverty reduction in the Northeast. In recent years, the Terra plant has been suffering from the environmental changes caused by agricultural activity and livestock farming, practices that generate environmental impacts and soil degradation. The soil cover is spread on the surface of the land in order to protect them from the effects of degradation. Soil cover also influences the reduction of water use. The objective of this study was to evaluate the use of carnauba bagana as a soil cover for the growth and production of coriander in the semiarid region. The experiment was carried out in the municipality of Pentecoste, semi-arid region of Ceará. The design used was of randomized blocks, in plots of 10sqm and subplots of 1sqm. The growth variables analyzed were plant height and number of leaves and the production variables were dry mass and freca of shoot and root, besides productivity. It was observed that by adding almost 50% plant cover of carnauba bagana (approximately 8 t.ha-¹) a better root dry mass index was obtained. New studies should be conducted to identify the best way to utilize this by-product of carnauba, allowing man to attach to the field and proper disposal of carnauba bagana.
