INFLUENCE OF AGE AND CLIMATE IN THE PRODUCTION OF CENCHRUS PURPUREUS IN THE ECUADORIAN AMAZON REGION

Abstract

The objective of this study was to establish the relationship between age and climatic elements and the performance indicators of Cenchrus purpureus vc. Maralfalfa. Sprouting ages at 30, 45, 60, 75 and 90 days were evaluated. A randomised block design was used and the variables green and dry matter yield of leaves and stems, total dry matter and dry matter production were measured. Second degree equations were established for age and the variables evaluated, as well as multiple linear curves to determine the relationship between climate factors and performance indicators; in the latter case, age was always used as an independent variable. The regression coefficients were higher than 0.96. The established regression equations explain the close relationship between age, performance, and climatic elements. These can be used to design efficient management systems of this variety. Age had a marked effect on the behaviour of the indicators evaluated, as performance increased.
