KONTRIBUSI TANDAN KOSONG DALAM MENINGKATKAN PENGARUH PUPUK ANORGANIK TERHADAP PRODUKSI KELAPA SAWIT

Sustainable intensification of oil palm plantations faces the challenge decreasing soil fertility and increasing price inorganic fertilizers. Organic matter plays an important role in maintaining fertility. Empty fruit bunches (EFB) are main co-product mills that have potential to be used as a source organic nutrient sources. This study aims reveal effect application empty effectiveness substituting fertilizers for components production. The number female inflorescence, FFB average weight were observed 3 years on aged 8, 9 10 years. Application EFB + 70% recommended fertilizer. fertilizer is 8 kg per tree (N P K Mg 14-28-6-2 +0.5 B). applied one layer mulch with size 3x4 m dead net. results showed could increase flowers plants (1-2 after application), while was only at age (0 application) both production components. year EFB+70% (age ) higher than plants. can contribution nutrients from compared solely.
