Growth and production of paddy rice (Oryza sativa L.) in various planting systems and types of liquid organic fertilizers

Abstract

Abstract This study aims to determine the growth and production of rice in various planting systems and types of liquid organic fertilizer. The research was conducted in Rijang Panua Village, Kulo District, Sidenreng Rappang Regency from May to August 2016. The research was conducted based on a split plot design with main plot set was planting system consisted of three levels, namely: the tile planting system (20 cm × 20 cm), the legowo planting system 4:1 (40 cm × 20 cm × 20 cm), and 2:1 legowo planting system (40 cm × 20 cm × 20 cm). Subplot was type of liquid organic fertilizer made from three types of raw material, namely Gliricidia tree leaves, banana weevils, and Gliricidia leaves + banana weevil. The results show that there was a significant interaction effect between the two treatments on parameters of plant height, number of grains per panicle, production per plot and production per hectare. The combination of 2:1 legowo planting system and the liquid organic fertilizer made from Gliricidia leaves + banana weevil gave the highest yields on production per hectare (5.55 ton.ha −1 ). Highest number of productive tillers and an earlier flowering age were observed in the 2:1 legowo planting system (32.26 tillers and 60 days after sowing).
