The Brazilian semi-arid region has water restrictions, which justifies the cultivation of cowpea associated with sustainable soil management practices. Thus, the objective of this work was to evaluate the water demand and growth of cowpea under doses of sheep manure in the Cariri region of Paraíba. The experiment was carried out in the municipality of Soledade, Paraíba, using a completely randomized design, testing six doses of sheep manure (D1 = 0%, D2 = 5%, D3 = 10%, D4 = 15%, D5 = 20% and D6 = 25%, m/m) and 4 repetitions, totaling 24 experimental units. Water demand was determined during cultivation and at 10 and 22 days after sowing, the length of the main branch was measured, the leaf area estimated and the root, shoot and total dry mass determined. It was verified that doses of sheep manure increase the water demand and the growth of cowpea in the Cariri region of Paraíba, being recommended the application of a dose of 13.51±1.98% of sheep manure.
La región semiárida brasileña tiene restricciones hídricas, lo que justifica el cultivo de caupí asociado a prácticas de manejo sostenible del suelo. Así, el objetivo de este trabajo fue evaluar la demanda de agua y el crecimiento del caupí bajo dosis de estiércol de oveja en la región de Cariri, Paraíba. El experimento fue realizado en el municipio de Soledade, Paraíba, utilizando un diseño completamente al azar, ensayando seis dosis de estiércol de ovino (D1 = 0%, D2 = 5%, D3 = 10%, D4 = 15%, D5 = 20% y D6 = 25%, m/m) y 4 repeticiones, totalizando 24 unidades experimentales. Se determinó la demanda de agua durante el cultivo ya los 10 y 22 días después de la siembra se midió el largo de la rama principal, se estimó el área foliar y se determinó la masa seca radical, aérea y total. Se verificó que las dosis de estiércol de ovino aumentan la demanda de agua y el crecimiento del caupí en la región de Cariri de Paraíba, siendo recomendada la aplicación de una dosis de 13,51±1,98% de estiércol de ovino.
