Abstract
Se evaluó Ulex europaeus como abono verde sobre la producción de biomasa y proteína en acelga (Beta vulgaris L. var. Cicla). Los tratamientos fueron 1,6 kg de Lupinus albus; 1,6 kg de U. europaeus y un testigo absoluto. Las unidades experimentales fueron parcelas de 2 m2, dispuestas en bloques completamente al azar, con cuatro repeticiones. Los datos se sometieron a un ANDEVA y a la prueba de Tukey con 5% de significancia. Transcurridos 60 días de la incorporación, se establecieron plántulas de B. vulgaris var. Cicla. La producción de biomasa y análisis proximal se evaluó a los 120 días del establecimiento; y el análisis de suelo, a los 184 días de la incorporación. U. europaeus generó un 42% más de materia verde respecto del testigo (p≤0,05), sin diferencias con lupino (p>0,05). No se encontraron diferencias (p>0,05) en la producción de materia seca. El contenido de proteína fue 14% superior (p≤0,05) en U. europaeus y L. albus respecto del testigo. El nivel de NPK en el suelo fue mayor en U. europaeus. El aumento de materia verde y proteína en B. vulgaris var. Cicla, así como de NPK en el suelo, avalan el uso de U. europaeus como abono verde.
We assessed the response of biomass and protein production of chard (Beta vulgaris L. var. Cicla.), by using Ulex europaeus vs. Lupinus albus as green manure. Treatments were 1.6 kg of L. albus; 1.6 kg of U. europaeus and absolute control. The experimental units were 2 m2 plots arranged in a randomized complete block with four replications. The data were analyzed by ANOVA and Tukey’s tests at 5% significance. Plants of chard were established after 60 days of the incorporation of the green manure. Biomass production as well as proximal analysis was performed at 120 days after establishment. In addition, a soil analysis was performed at 184 after incorporation of green manure. The utilization of U. europaeus improved in 42% fresh biomass production when compared with the control (p≤0.05), however no differences were observed when it was compared with lupin (p>0.05). No differences were observed for dry matter production among the treatments (p>0.05). Water content it was 14% greater for treatments that included green manure. The levels of NPK in the soil were greater for U. europaeus treatment. The increase of green matter and protein in chard as well as the increase of NPK levels in the soil, support the use of U. europaeus as green manure.
