Summary in the original language of the document
This research was conducted to study the direct fertilization combining 0 and 160 kg N ha-1 of cattle manure and green manure as branches of pigeon pea (Cajanus cajan L.) and their residual effects on two population densities of roquette (Eruca sativa Miller) crop, in Seropédica, Rio de Janeiro, Brazil. Yield, number of leaves plant-1, leaf area index, shoot fresh weight, stems dry matter, roots dry matter, leaves dry matter, total dry matter and plant height were measured. The experiment was a randomized block design set as a factorial 2 x 2 x 2, and three replications: 0 and 160 kg N ha-1 of cattle manure, 0 and 160 kg N ha-1 of branches of pigeon pea and 500,000 and 1,000,000 plants ha-1. The results indicate that the population density of 500,000 plants ha-1 showed, in general, better results in terms of yield per plant. However, 1,000,000 plants ha-1 had significantly higher yield per hectare. It was observed that there was no significant difference between the use of cattle manure and branches of pigeon pea on the yield of roquette under directly fertilization and residual effect of fertilization. The replacement of cattle manure by branches of pigeon pea associated with 1,000,000 plants ha-1 showed less loss of roquette yield under the residual effect of fertilization.
Summary translation
Investigou-se a adubação orgânica direta combinando esterco bovino, ramas de guandu (Cajanus cajan L.) e seu efeito residual na cultura da rúcula (Eruca sativa Miller) cultivada em duas densidades populacionais no Município de Seropédica, RJ, sobre produtividade, índice de área foliar, número de folhas planta-1, matéria fresca parte aérea, matéria seca de ramos, raízes e folhas, matéria seca total e altura de planta. O delineamento experimental adotado foi blocos ao acaso em ensaio fatorial 2 x 2 x 2 e três repetições: 0 e 160 kg N ha-1 de esterco bovino, 0 e 160 kg N ha-1 de ramas de guandu e 500.000 e 1.000.000 plantas ha-1. Os resultados indicam que a densidade populacional de 500.000 plantas ha-1 apresentou, em geral, melhores resultados em termos de rendimento por planta. No entanto, 1.000.000 plantas ha-1 apresentou produtividade significativamente maior. Observou-se que não houve diferença significativa entre o uso de esterco bovino e ramas de guandu na produtividade de rúcula sob adubação direta e seu efeito residual. Sob efeito residual, a substituição do esterco de gado por ramas de guandu utilizando 1.000.000 plantas ha-1 apresentou menor perda de produtividade.
