Effectiveness of Planting Pattern Systems and Types of Varieties on the Growth and Production of Rice Plants (Oryza sativa L.)

Abstract

Jajar Legowo planting pattern technology is a planting technique designed to arrange the planting pattern in order to increase production. The purpose of this study is to analyze the Jajar Legowo planting system and different varieties on post-harvest rice production and proximate content. There are 2 types of research methods: quantitative analysis of post-harvest rice, which includes proximate content, and rice cultivation using a Randomized Block Design (RBD) with 5 repetitions. The treatments consist of two factors: the main factor is 2 types of seed varieties (V1) Inpari 32 HDB and (V2) Inpari 49 Jembar, and the second factor is the type of planting system (J1) Jajar Legowo 2:1, (J2) Jajar Legowo 3:1, (J3) Jajar Legowo 4:1. The parameters analyzed are: plant height, number of tillers, number of panicles, wet grain weight, dry grain weight, and moisture content. The research location is in Getas Village, Tanjunganom District, Nganjuk Regency, East Java, at an altitude of 79.9 meters above sea level, with a soil pH of 6.0, alluvial soil type, surrounding temperature of 30-32 degrees Celsius, and about 85% humidity, conducted from April to October 2025. The results showed that the growth and yield of the Inpari 49 variety were higher than Inpari 32 in all planting system combinations
