Popis: The dose effects of green manure in vegetable crops production are still poorly understood. There are few scientific studies indicate that increasing the dose may influence plants characteristics. The objectives were to evaluate the effect of doses of velvet bean green manure on growth and yield, the partitioning of dry matter and nitrogen (N) in plants of broccoli, as well as determine the apparent recovery and physiological efficiency of use N. We established four treatments plus a control. The treatments consisted of four levels of green manure: 0, 3, 6, 9 t ha-1 on a dry matter basis, with the addition of 12 t ha-1 of compost. Doses of green manure applied influenced the growth and yield of broccoli. The distribution of dry matter between plant parts of broccoli is not influenced by the doses of green manure. Doses of green manure influenced the amount of N accumulated in the inflorescence and whole plant of broccoli. The apparent recovery of N from green manure and efficiency of N use by plants of broccoli are positively associated with the applied doses.
