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