Corn (Zea mays L.) productivity in acid dry land used zigzag planting method

Abstract

Zigzag planting method technology was an alternative technology to increase plant population without affecting plant growth and development. The purpose of this study was to determine the productivity of corn with different planting methods, such as the zigzag and the linear planting method applied by farmers on acid dry land in the Lampung area. The research was conducted at the Natar Experimental Station in Negara Ratu Village, Natar District, South Lampung Regency, Indonesia from March to June 2020. The study used a two-factor randomized block design, namely the hybrid corn varieties (NK Sumo, NK 22 Jumbo, and NK Super) and the planting methods (zigzag and linear planting methods). Observations were made on ten plants per sampling plot, which were determined randomly. The results showed that the zigzag planting method produces a higher yield (8.16 tons/ha) compared to the linear planting method (4-5 tons/ha grain yield). Moreover, the zigzag planting method increased the plant population by 80% without disturbing plant growth and development. The zigzag planting method was able to increase corn production by 30-40%.
