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

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).

Growth and Yield of Soybean on Various Types and Concentrations of Liquid Organic Fertilizer in Ultisols

“…Puteri et al (2021) reported that plant height, number of leaves, stem diameter, ear weight, and ear length of sweet corn were not affected by Tithonia (Tithonia diversifolia) LOF. Combining the planting system and the Gliricidia leaves + banana weevil LOF resulted in higher rice yields than Gliricidia tree leaves or banana weevils LOF (Mollah et al, 2021). Plant height, number of leaves, and flowering time were higher in the 15 ml L -1 liquid fertilizer treatment than in the 20 ml L -1 LOF or control treatments (Ridwan et al, 2020).…”

“…The use of LOF also boosted rice production. A 2:1 legowo planting system and a liquid organic fertilizer made from Gliricidia leaves + banana weevil produced the highest yields per hectare (Mollah et al, 2021).…”

Assessment of Increasing Rice Plant Index 400 with the Application of Environmentally Friendly Rice Cultivation Technology in Irrigation Land, Banjar City, West Java

“…Research by [16] shows that the use of organic materials can significantly increase rice yield (16%). A study by [17] indicates that the use of organic fertilizer significantly affects the number of productive tillers and the number of leaves per rice plant.…”
