Productivity and persistence of red clover, Egyptian clover and chicory in four locations in Santa Catarina State

Abstract

The objective of this network assay was to evaluate the performance of four agronomic forages potential for Santa Catarina, State. Were evaluated cultivars of Trifolium pratense (cv. Quiniqueli and PG626), Trifolium alexandrinum (cv. Elitte II) and Cichorium intybus (cv. Puna II). The experiments were conducted in four physiographic regions of the State: West, South Plateau, North Plateau and Midwest. Was used a randomized block design with three replications. The cuts were made from June 2010 to January 2012. In the first year of evaluation, the two cultivars of T. pratense were the most productive in the West, not differing of C. intybus in other regions. During the first year of evaluation, the two cultivars of T. pratense were the most productive in Western, not differing from chicory in other regions. In the evaluation of the second year, the chicory was the most productive material in South Plateau, North Plateau and Midwest, being lower than the genotypes of red clover only in the West. The two cultivars of red clover showed similar behavior among them in all regions. T. alexandrinum had an annual cycle and low yields at all locations. Forage Cichorium intybus (cv. Puna II) presented a favorable yield potential for cultivation in Santa Catarina, State, with emphasis on the Northern Plateau region. Key words: Pasture. Trifolium pratense. Trifolium alexandrinum. Cichorium intybus.
