Application of liquid organic fertilizer and N, P, K to the properties of soil chemicals and growth of rice plant

Abstract

Rice is a food source of carbohydrate which is a staple food in Indonesia. One way to increase production is to control soil productivity by using organic and inorganic fertilizers. This research was conducted to determine the effect of organic fertilizer combined with N, P, K inorganic fertilizers on the chemical properties and growth of rice plants. This research was conducted from June-September 2018. The experimental design was carried out using a Randomized Block Design (RBD) consisting of 10 treatments with three replications. The treatment combination consisted of liquid organic fertilizer dosages of 0 ml/L, 2.5 ml/L, 5 ml/L 7.5 ml/L and 10 ml/L and inorganic fertilizer N doses of 0 kg/ha, 50 kg/ha, 100 kg/ha, 150 kg/ha 200 kg/ha. inorganic P 0 kg/ha, 37.5 kg/ha, 75 kg/ha, 112.5 kg/ha, 150 kg/ha inorganic K 0 kg/ha, 12.5 kg/ha, 25 kg/ha, 37.5 kg/ha 50 kg/ha. The results showed that the combination of organic and inorganic fertilizers N, P, K did not influence the soil chemical properties and plant growth. The highest yields on plant height after 8 WAP were shown in treatment D (1 dose of LOF + 1 N, P, K) with 58.03 cm.
