Farmers understanding and practices on shading and pruning for Arabica coffee - A survey and analysis on the effects to the yields

Abstract

Abstract This study aimed to identify and formulate the influence and correlation of farmers’ practices and understanding related to the shading and pruning on the yiels of their Arabica coffee. The research was carried out in Bolokan Village, Lembang Tiroan Bittuang, Tana Toraja Regency, South Sulawesi-Indonesia. The research was in the form of surveys (study literature, observations, and interviews), with the selection of samples carried out deliberately (purposive sampling). The data was analysed with multiple linear regression using SPSS software. The results showed that the different levels of practices related with shading and pruning management provided significant effect and correlation with the yields of coffee plants. The generated multiple linear regression equation was Y = 27.983 + 1.131X1 + 0.591X2 + 2.575X3 + 1.050X4 + 0.820X5 + 1.967X6 + 1.185X7 + 0.313X8 + 0.823X9. Factors from aspects of maintenance techniques related with shading and pruning could increase the production and productivity of Arabica coffee plants. Variables of plant height adjustment, flowering and fruiting stimulation through shading, production pruning, understanding of shade plants benefits and pests and diseases control were stated to have an influence on yields (fruit) of coffee plants, while shade management, pruning time, rejuvenation pruning, and permanent shade plants were declared to have no significant effect.
