Avaliação da promoção de crescimento de sorgo granífero [Sorghum bicolor (L.) Moench]com uso de Trichoderma spp.

Abstract

Grain sorghum [ Sorghum bicolor (L.) Moench], which originated in Africa, is a cereal crop that belongs to the Poaceae family and is valued for its ability to grow in adverse conditions, such as arid soils and hot climates. In this study, the growth of grain sorghum in the Cariri Paraibano region was assessed by applying different doses of Trichoderma , the dosages being 0, 50, 150 and 200ml of Trichodermam diluted in 5 liters of water. The research was conducted in the Experimental Area of LAFISA (Semi-Arid Plant Health Laboratory), located at the Federal University of Campina Grande, Sumé Campus - PB, within the scope of the Semi-Arid Sustainable Development Center (CDSA/UFCG). The results showed that the Trichoderma harzianum doses of 150 and 200 ml/5L were the most efficient in promoting leaf area growth and increasing the diameter of the sorghum stem. These results indicate that the use of Trichoderma spp. is an effective alternative for improving the development of grain sorghum plants in Cariri Paraibano, which could contribute significantly to increasing agricultural production in the region.
