Nitrogen fertilization in common bean under no-tillage grown after green manures provides different response patterns. Thus, the study aimed to evaluate the effect of N doses on coverage and the use of different vegetation covers on the development and yield of irrigated common bean, grown in no-tillage. The work was conducted during the years 2001 and 2002, in an area located in the city of Selvíria-MS, Brazil. The experimental design was randomized blocks in factorial arrangement (7 x 6) with four replications. The first factor it was composed of seven soil cover managements (Pennisetum glaucum, Sorghum bicolor, Zea mays,Cajanus cajan, Crotalaria spectabilis, Mucuna aterrima and a fallow area), while the second factor consisted of five N top-dressing doses (0, 25, 50, 75, 100 and 125 kg ha-1). It were mensured the variables: foliar N content, dry matter of plants and yield components (number of pods plant-1, number of grains plant-1, number of grains pod-1 and mass of hundred grains) at five plants each plot; final population of plants and grain yield. Nitrogen top-dressing doses on irrigated common bean influenced only variable dry matter of plants, while the different soil covers does not influence any agronomic characteristic this culture.
