Study on the relationship between climate and coffee production in upper Northern Thailand
This study was started in 1986 to define the influence of climatic factors on the growth and production of Arabica coffee and is conducted at the Nong Hoy and Chang Khian Research Station (1000 and 1,300 m asl. resp.). Research in the period January to December 1987 concentrated on the growth rate of 5 selections of Catimor, i.e. H 528/49, H 420/49, H 528/25, H 528/21 an H 361/3, and red Caturra. Growth increments in terms of plant height, stem diameter and length of branches were measured. Results show that these components increased considerably at Nong Hoy during the rainy season from June to October and then slowed down in the early cool season in November - December. The growth rate at Chang Khian was found to fluctuate slightly during the rainy season followed by a slow-down in the cool season. Generally, the total growth increment was relatively higher at Chang Khian than at Nong Hoy, especially the Catimor selection H 361/3
