Objetivando avaliar o efeito da adubação fosfatada, nitrogenada e introdução de leguminosas na recuperação e utilização de pastagem de capim-jaraguá foi realizado um estudo utilizando-se um pasto de 25 anos em solo Podzolico Vermelho Amarelo com concreções, para engorda de novilhos. Entre 1978 e 1980 foram testados os seguintes métodos de recuperação: A- limpeza das invasoras; B- limpeza das invasoras mais fósforo (50kg de P2O5/ha) mais leguminosas; e C- limpeza das invasoras mais fósforo (50kg de P2O/ha) mais nitrogênio (75kg de N/ha). No primeiro período experimental, as pastagens sob o método A foram utilizadas nas taxas de lotação de 0,5, 1,0 e 1,5 an./ha e os métodos B e C nas de l,0, 1,5 e 2,0an./ha. Neste período, método C foi estudado somente por 196 dias devido a acentuada degradação ocorrida nas pastagens, enquanto a comparação dos métodos A e B continuou por ate 364 dias. No primeiro período experimental, enquanto o método C foi testado, não houve diferenças significtivas nos ganhos de peso por animal e por hectare entre os métodos A,B e C, possivelmente devido ao pequeno período de comparação. Houve diminuição no ganho diário com o aumento da taxa de lotação nas pastagens sob os métodos A e B. Na comparação prolongada dos mesmos, independente de taxa de lotação, o metodo B foi superior em ganho de peso por animal e por hectare. Estas diferenças foram atribuidas ao melhor valor nutritivo proporcionado pelas leguminosas. |

Natural and beneficial associations between plants and bacteria have demonstrated potential commercial application for several agricultural crops. The sunflower has acquired increasing importance in Brazilian agribusiness owing to its agronomic characteristics such as the tolerance to edaphoclimatic variations, resistance to pests and diseases, and adaptation to the implements commonly used for maize and soybean, as well as the versatility of the products and by-products obtained from its cultivation. A study of the cultivable bacteria associated with two sunflower cultivars, using classical microbiological methods, successfully obtained isolates from different plant tissues (roots, stems, florets, and rhizosphere). Out of 57 plantgrowth-promoting isolates obtained, 45 were identified at the genus level and phylogenetically positioned based on 16S rRNA gene sequencing:42 Bacillus (B. subtilis, B. cereus, B.thuringiensis, B.pumilus,B. megaterium, and Bacillus sp.) and 3 Methylobacterium komagatae.
