Effect of liquid organic fertilizer on the rice varieties field production

Abstract

Rice production for rice supply in Indonesia still needs to be increased in line with the growing population growth. One effort that can be done by planting high-yielding rice varieties and using liquid organic fertilizer. This study aims to obtain the rice variety which is the best in production among the varieties studied in this study and the appropriate concentration of liquid organic fertilizer is applied. The study was conducted in Sendang Rejo Village, North Sumatra Province, Indonesia. The study used a Randomized Block Design with two treatment factors, namely: Liquid Organic Treatment Factor consists of 4 levels of treatment: Mo=Without liquid organic fertilizer. M1 = 3 cc/l of water. M2 = 6 cc/l of water. M3 = 9 cc/l of water. Variety treatment factors consisted of 3 types of paddy rice varieties: V1 = Ciherang. V2 = Inpari 30. V3 = Inpari 32. The results showed that the highest grain production is found in the treatment of liquid organic fertilizer 6 cc/l water with a production of 27.48 g per plant (4.40 tons/ha). There is a tendency of the highest production found in the variety of Inpari 32 with a production of 26.38 g per plant (4.22 tons/ha).
