Resumo: The work was carrying out at Centro de Ciências Agrárias –UFPB, farm Chã-de-Jardim, in February to June, 2004, with the objective of evaluate effect of nitrogen levels used by fertirigation, on bell pepper growth, development and yield cultivated on protected environment. Experimental design used was randomized blocks with five treatments (0, 100, 200, 300 e 400 kg.ha-1) and four replications, in a total of 20 plots. Each plot was composed by 18 plants variety All Big, in a total of 360 plants. It was evaluated higher of plants, leaves number, foliar area (FA), foliar area index (FAI), floration and frutification beginning, length, diameter and, fruits medium weight, number of fruits per plant and yield for commercial and no commercial fruits. It was determined relations among FA and FAI with yield. The greenhouse thermal variation variation during culture cycle was 7 to 10º C. For reaching maximum it was necessary 1.330 degree-days accumulated, corresponding, in that year, 69 days after transplanting, independing of nitrogen level used and for transplantig-harvest period that thermal accumulation
