Effect of cow manure and spacing on growth

With the aim of maximizing the production of chia, a food crop currently being popularized in the area, the present study assessed the effect of cow manure and furrow spacing (30 cm; 45 cm and 60 cm) on chia growth and yield under Buzi bulenga edapho-climatic conditions.The methodological approach consisted in setting up a three-block, three-column experimental set-up (Greco-Latin square set-up), with three treatments, resulting from the combination of variants of two tested factors (fertilizer and row spacing). The results obtained were such that, during vegetative growth, the height of Chia plants did not depend on row spacing or fertilizer until the 15th day of evolution. The difference was observed from day 30 to the end of vegetative growth. Growth in height was therefore inversely proportional to spacing. The 30 cm spacing produced plants with greater height development than the other spacings, followed respectively by the 45 cm spacing and the 60 cm spacing (ppds =13.36; =0.05).
