Com a expansão da cultura da soja na região de baixas latitudes do Brasil, faz-se ne-cessário realizar estudos para estabelecer tecnologias para seu cultivo, já que poucas pesquisas ali foram feitas. As recomendações de adubação e calagem são efetuadas através de adaptações de ou-tras regiões do País. Com o objetivo de avaliar a resposta à adubação fosfatada e potássica, foi conduzido, em 1984/85 e 1985/86, um experimento no município de Balsas, MA, com doses de K (0, 40, 80 e 120, no primeiro ano, e 0, 50, 100 e 150 kg de K2O/ha no segundo ano) e de P (0, 80, 160 e 240, no primeiro ano e 0, 100, 200 e 300 kg P2O5/ha no segundo ano) aplicadas no sulco de plantio. O experimento foi realizado em um Podzólico Vermelho-Amarelo, tendo sido cultivado anteriormente com arroz de sequeiro por dois anos, sem adubação e sem calagem. Foram incorpo-radas 3 t/ha de calcário, mais 10 kg de Zn/ha. As sementes receberam inóculo de Bradyrhizobium japonicum (200 g/50 kg de sementes). Os resultados mostraram grande resposta a P, com pontos de máxima produção na dose próxima e 200 kg P2O5/ha e dose econômica de 150 kg/ha, nos dois anos de cultivo. Para o K a dose que proporcionou produção máxima foi de 50 kg de K2O/ha, com dose econômica abaixo de zero. |

Products made from piperine are important for the management of pests, but allelopathic studies for these products are also relevant. The aims of the study were: First, to evaluate the effect of piperine on Spodoptera frugipera and Diatraea saccharalis and as second objective, to evaluate the allelopathic and phytotoxicity effects of this compound in the germination and growth of several vegetables. The piperine was applied on eggs laid by both lepidopteran species and on sand used as a substrate for the seeds plants. The hatching in recently laid eggs of S. frugiperda and D. saccharalis with piperine was lower than older eggs. Allium cepa presented a higher percentage of germination at 0.5 and at 5.0 mg/Kg and Lactuca sativa the lowest. The highest length of seedling was for the A. cepa.
