Yield of coffee is affected by some anatomical- as well as morphological properties and physiological activities. Coffee is a C3 plant that has a photosynthetic saturation at a certain light intensity. To know some anatomical-, morphological- and physiological characteristics those affect growth and yield of Robusta coffee, a study has been done at the Indonesian Coffee and Cocoa Research Institute, Jember, East Java, Indonesia. Fully expanded leaves of eight clones have been measured on their area, stomata density, stomata pores area, palisade index, chlorophyll index, and photosynthetic rate. Clones measured were BP 42, BP 358, BP 409, BP 534, BP 936, BP 939, BP 961 and SA 237. Measurement was done at Kaliwining Experimental Station, Jember, Indonesia, at the altitude of 45 m above sea level. Measurement was stressed to describe the dynamic response curve model and to correlate yield to other parameters. The most dominant parameter that affect yield was determined.
