AGRONOMIC FEASIBILITY OF GROWING CHIA IN NORTHWESTERN RIO GRANDE DO SUL

Abstract

The aim of this work was to evaluate the development of Chia at different sowing times and plant spacings. The experiment was conducted in a commercial area located in the Northwest Region of RS in the municipality of Novo Machado. The experiment was conducted in a bifactorial arrangement with 2 spacings and 3 sowing times, with four replications. The factors analyzed were three different sowing times (January 15 and 30, and February 15) combined with two spacings (17 and 45 cm). The following parameters were evaluated: mean plant height, ear length, yield, weight of one thousand seeds, germination and first germination test count. The variable percentage of germination and its derivations were transformed into arcsin (X/100)1/2. The study showed that chia can be cultivated in the region, achieving good results for the parameters evaluated, mainly for grain yield. Sowing carried out in January and at the spacing of 17 cm between rows provided the best results.
