Are Chilean Pasture Seed End-Users Adopting New Species? Trends and Joinpoint Regression Analysis of the Last 19 Years of Seed Imports

Pastures are important for the agricultural sector as forage, recreational and sports systems. The Chilean pasture seed market is highly dependent on introduced genetics; however, effect of climate change conditions can modify options. objective this study was to quantify changes seeds sown by end-users, metric tons (Mt) or proportion total (PT), based 19 years imported seed. Mann–Kendall test joinpoint regression analysis were used estimate overall trends average annual percent (AAPC) whole period, respectively. Mt had an increasing trend AAPC (+5.7%), wherein a large PT corresponded ryegrasses (Lolium spp.) (0.681), with PT. Clovers (Trifolium decreasing (−2.9% −9.6% PT). For PT, main species perennial ryegrass (L. perenne L.) (0.357), Mt. As Mt, positive found plantain (P. lanceolata (+17.4%) chicory (C. intybus (+63.2%). Over period years, but not end-users have been adopting new use Trifolium spp.
