Daftar Isi:
- This experiment was aimed to study the effect of biofertilizer on growth of young Robusta coffee. New planting of Robusta coffee BP 42 x BP 358 was used with Randomized Complete Block Design and 3 replications. Treatments were fertilization as follows : P1 (20 g EMAS + 50 % recognized dosage of inorganic fertilizer (d.a.p.a.)), P2 (10 ml EM 4 + 50 % d.a.p.a.), P3 j (25 g OST + 50 % d.a.p.a.), P4 (5 kg manure + 50 % d a.p.a.) and P5 (d.a.p.a., 23 g Urea, 28 g SP36 and 16 g KCI). The results showed that sum couple, length and sum node of plagiotrophic stems were significantly different from 2 till 6 month after treatment, but it were not significantly different for height and stem diameter: Manure + 50 % d.a.p.a. was the best responses for all variables. EMAS + 50 % d.a.p.a. and EM 4 + 50 % d.a.p.a. had responses as good as inorganic fertilizer: Whereas, OST+ 50 % d.a.p.a. had the lowest responses for all variables.
