Resumen

GIULIETTI, Al; RUIZ, Om; PEDRANZANI, He  y  TERENTI, O. Effect of four vermicomposts on growth of Digitaria eriantha plants. Phyton (B. Aires) [online]. 2008, vol.77, pp. 137-149. ISSN 1851-5657.

In this paper, the effects of four vermicomposts are analyzed on a variety of growth and development parameters of Digitaria eriantha cv. Mejorada INTA. The vermicomposts used originated from cow, horse, goat and hen feaces combined with pure soil in the following proportions: T1: 0% worm humus + 100% soil; T2: 50% worm humus + 50% soil, and T3: 100% worm humus + 0% soil. Digitaria eriantha seeds were sown in trays which were kept under controlled light and moisture conditions. After the third week of treatment, the number of germinated seeds, and both leaf and root length and dry weight were determined. Best results for the analyzed parameters were observed using goat and hen vermicomposts. However, results were better using goat than hen vermicompost.

Palabras llave : Worm humus; Germination; Dry weight; Fresh weight.
