Pertumbuhan dan Produksi Beberapa Varietas Padi Sawah (Oryza sativa L.) pada Berbagai Jenis Pupuk Organik Cair di Kabupaten Batu Bara

Abstract

Rice is very important cultivated crop for mankind as half of the world’s population depends on it humanity as half of the world’s population depends on this crop as a source of food. Rice is a primary need for the people of Indonesia, as it is a source of energy dan carbohydrates for human life. This research aims to determine the growth and production of several varieties of lowland rice (Oryza sativa L.) with different types of liquid organic fertilizers in Batu Bara district. This research was carried out in Bangun Sari Village, Datuk Tanah Datar District, Batu Bara Regency with an altitude of ±9 meters above sea level from February to May 2024. This research used a Split Plot Design (RPT) using two factors. The first factor was the combination of fertilization consisting Without Liquid Organic Fertilizer + Farmer's Habitual Dose of Inorganic Fertilizer, Recommended Dose of Inorganic Fertilizer, Nasa Liquid Organic Fertilizer 8 ml/liter + Farmer's Habitual Dose of Inorganic Fertilizer, Fertilizer Vigorin Liquid Organic Fertilizer 8 ml/liter + Farmer's Habitual Dose of Inorganic Fertilizer, Kilat Liquid Organic Fertilizer 8 ml/liter + Farmer's Habitual Dose of Inorganic Fertilizer, MKP Plus Liquid Organic Fertilizer 8 ml/liter + Farmer's Habitual Dose of Inorganic Fertilizer. The second factor is lowland rice varieties consisting of Ciherang, Inpari 32, Mekongga and Mapan-05. The results showed that the variety treatment showed significant differences in the parameters of plant height and 1000 seed weight. Fertilization treatment had a significant effect on the parameters of grain weight per plot and production per ha. The interaction treatment had a significant effect on the parameters of panicle length, the number of total grains per panicle, the number of filled grains per panicle and the number of empty grains per panicle.
