Abstract

The aim of this research was to study the responses of coffee (Coffea canephora) grafting to holes biopore and NPK fertilizer dosages. The coffee plant used in this research was grafting coffee plant (25 years) which grafting from local robusta and stumb from Tugu Hijau clone. This research was conducted from Januari until Mei 2018, in Semendo Darat Ulu Subdistrict, Muara Enim Distict of South Sumatera. The research used Randomized Block Design (RBD) in factorials. Hole mad biopore had diameter as 10 cm and dept in as 100 cm. The first factor was the amount of biopore : without biopore holes (P1), 1 biopore hole/plant (P2), 2 biopore holes/plant (P3), 3 biopore holes/plant (P4), and 4 biopore holes/plant (P5). The second factor was the NPK fertilizer dosages : without NPK (Q1), 300 g/plant (Q2), 600 g/plant (Q3), and 900 g/plant (Q4). Each treatment combination was three replications so that there were 60 samples plant, each treatment unit was 1 plant, in each plant there are 3 samples of secondary branch. Based on the analysis unit of variance, between the amount of biopore holes and of NPK fertilizer was not significantly affect for all the variables, and nothing too for effect of NPK fertilizer dosages. There was a significant effect of the number of biopore holes on in the amount of branches of water, and and no significant effect on all other variables. Application of biopore as 4 holes / plant increased the number of flowers and fruit bunch and number of fruits / plants. Fertilizer dosage of 900 g / plant with also the followed by 4 holes of biopore/ plant reach number of fruit more 18 seeds / branch secondary sample was compared from controle treatment.
