Abstract

Barley (Hordeum vulgare L.) is a strategic crop for the Andean communities because it is not very demanding on soil conditions, tolerates low temperatures and can be used for both human and animal consumption. Frosts, on the other hand, are phenomena that usually occur in the Andes and can affect the proper development of crops. This research aims to illustrate the influence of frost on the yield and quality of barley in the central highlands of Peru. For this, two locations were chosen: Valle del Mantaro (11°50’33” S 75°22’45” W, 3200 m asl) and Ñahuimpuquio (12°19’35” S 75°04’00” W, 3630 m asl). A meteorological frost was recorded during the study. Four cultivars were evaluated, comparing seven yield variables and three quality variables. A randomized complete block design by locality was used. Statistical analyses were performed using the SAS program. The results obtained reflected that the occurrence of said frost during flowering compromised the adequate development of cultivars in Ñahuimpuquio; while, in Valle del Mantaro, there were no effects when it occurred during vegetative growth. Frosts that occur in sensitive stages of the crop can compromise yield and quality, as well as food sovereignty.
