The research work was conducted at the Experimental Station of Lagoa Seca, located at the Empresa Estadual de Pequisa Agropecuária da Paraíba, EMEPA-PB, with the objective of identifying the consequences of soil moisture content upon the growth variables of the bean (Phaseolus vulgaris L.) crop. The statistical design used was the randomized blocks, with four treatments and four replications. The treatments were based on different irrigation levels: 80, 160, 320 and 140.2 mm, distributed in the different phenological phases of the crop and based on the results of the previous studies and in the soil humidity. The effects of the different irrigation regimes were evaluated by means of the growth variables, while total phytomass, leaf area, leaf area index, net assimilation rate and leaf area ratio which showed differentiated values in which response to the water treatments employed, with increased values in plants with higher supplies of water.
