The purpose of the present work was to evaluate the behavior of buckwheat in relation to different harvesting times in five locations in the province of Valdivia, Chile, harvesting times: 25 February, 5 March, 12 March and 20 March. During the performance of this research the following agronomic characters were analyzed: plant height, number of inflorescence per plant, weight of 100 grains, yield and harvesting index. The grain quality characters analyzed during this research were: weight of hectoliter, chlorophyll content and protein content. The results obtained in this trial, from a random complete block design with four replicates per location, were submitted to an analysis of variance. Later, a joint analysis of treatments was carried out in a factorial way, where the single effects of harvesting time, location and interaction of harvesting time/location were studied. Significance of differences between means was analyzed through Tukey's test. In regard to yield and exportable quality, two harvesting times, 25 February and 5 March (14 and 15 weeks from sowing to maturity, respectively), proved to be the most adequate, showing yields ranging from 33 to 36 qq/ha, with chlorophyll contents approximating to 1.3% and protein contents ranging from 13 to 14%. The best locations for buckwheat growth were Pelchuquin and Lanco, which exhibited yields of 37 qq/ha, grain chlorophyll contents close to 1.3% and protein contents of 14%.
