Analysis on correlation of cultivation practices on production of Arabica coffee

Abstract

This paper presents the results of a study which was conducted to analyze the effects of maintenance practices of Arabica coffee on production. The location of the study was in a coffee production center of Tompobulu Subdistrict, Gowa Regency, Province of South Sulawesi, Indonesia. The research was in the form of a survey supported by literature study, observation, and interviews. Sample selection was purposive sampling and analyzed by multiple linear regression data. The results show that coffee productivity in Cikoro Village, Tompobulu Subdistrict, Gowa Regency is still low at 0.53 kg per tree. The multiple linear regression equation of Arabica coffee productivity obtained is Y = 351,487 + 53,331X1 + 5,324X2 + 7,108X3 + 1,967X4 + 5,080X5 + 3,889X6 + 5,407X7 + 9,420X8 + 5,307X9. Fertilizer dose and rejuvenation trimming variables had very significant effects. Other variables, namely fertilization frequency, fertilization method, fertilization time, shape trimming, production pruning, sanitation, and pest control, did not significantly affect the productivity of arabica coffee plants. Maintenance practices could increase the production and productivity of Arabica coffee plants in study location, especially on fertilizer dosage aspects and rejuvenation trimming.
