Some aspects of water relations and dry matter production of coffea arabica l. in Kenya

Abstract

Field and greenhouse studies were carried out to understand some aspects of water relations and dry matter production in Coffea Arabica L. Leaf water potential was found to be the most suitable technique for expressing internal water balance. The leaf water potential at which important plant processes start getting limited was found to be -20 bar. It has therefore, been suggested that this is the time when coffee should be irrigated
