Resumen:
Water isone of the morelimiting factors forecophysiological development of cultures
compromising the growth and yieldof plants, notablyincowpea, fact compounded whengrown
insemiarid region, characterized bywater limitation, so the oftechniqueswater catchmentand
identificationof genotypestolerantarealternativeinproduction system. Withthisstudy focuses
onthe ecophysiologyand economic aspectsofbean genotypesunderwater
conservationtechniquesin situ, in order to relate therational use of waterto sustainable
productionof the cropin the semiaridParaiba, identifying more resistant materials. The
experiment was realized on fieldof the Federal Universityof CampinaGrande, UFCG,
PombalCampus, PB, usinga randomizedblock design with factorialschem, 6x4, studyingfour
techniquesofwater harvestingin situandsixcowpeagenotypes plantedat a spacing of0.5mx0.5m,
with four replicationsand theexperimental parcelconsists of 24plants, being12 useful.It was
studedthe growth, physilogical andproductionvariables on genotypesunder techniques and
qualityandeconomic aspects from yield. The dataweresubmitted to analysisof variance, F test,
testand(Tukey)mean comparisonfor factorgenotypes andwater conservation techniques.The
semiarid region is passive to the cultivation of cowpea, with the use of techniques of water
harvesting an alternative to the producer, among them is indicated in ridge cultivation, by
providing better performance when compared to control, especially the cultivar Costela de
Vaca and genotype BRS Guaribaby presenting the best value in relation to other.
