Abstract
The use of organic fertilizers combined with chemical fertilizers is a form of integrated fertilization that can enhance plant production efficiency. It helps plants grow well and produce high-quality yields. The application of organic fertilizers improves soil fertility, making the soil more suitable for plant growth, thus allowing plants to better absorb nutrients from chemical fertilizers. This experiment aimed to study the effect of integrating organic and chemical fertilizers on the yield enhancement of Arabica Coffee. A Split plot experimental design with three replications was used, consisting of the main factor, which was chemical fertilizers at 4 levels: 0 (no chemical and organic fertilizer), 100% of the recommended rate (220-92-45 g N-P2O5-K2O per plant), 75% of the recommended rate (165-69-34 g N-P2O5-K2O per plant), and 50% of the recommended rate (110-46-23 g N-P2O5-K2O per plant). The secondary factor was organic fertilizer (cow manure) at 5 levels: 0, 1.25, 2.5, 5, and 10 kg per plant. The results showed that integrating organic and chemical fertilizers to increase the yield of Arabica coffee. Using organic fertilizer at 5 kg of per plant combined with chemical fertilizer rate 220-92-45 g N-P2O5-K2O per plant resulted in the highest yield of Arabica coffee, with a value of 1,130.60 kg per rai, significantly higher than other treatments. Additionally, this combination also resulted in the highest net profit, which amounted to 19,846.26 baht per rai.
