Kenaf performance in northwestern Argentina

Industrial Crops and Products, 1996
Abstract With increasing worldwide use of newsprint and wood products, the demand for nonwood fiber sources such as kenaf is expected to grow. Extensive studies were initiated to determine the potential for cultivation of kenaf in Argentina. Kenaf was grown at five locations in northwestern Argentina (Alberdi, Metan, Pichanal, Yuto I and Yuto II ...
