Respon Pertumbuhan dan Produktivitas Dua Varietas Padi (Oryza sativa L.) pada Sistem Tanam Mekanis dan Manual)

Abstract

Plant cultivation techniques using agricultural mechanization (rice transplanter planting machines) and early-maturing and high yielding varieties may increase crop productivity and farmers’ income. The application of the rice transplanter jajar legowo can increase rice crop productivity and planting costs by increasing the plant population and reducing labor and planting time. This study aimed to determine the growth and productivity of Inpari 32 and Inpari 42 varieties with different techniques in irrigated land. This research was conducted from April to July 2019 in Aneuk Glee Village, Indrapuri District, Aceh Besar using a randomized complete block design (RCBD) with two factors and four replications. The factors were varieties (V) consisting of Inpari 32 (V1), Inpari 42 (V2), and planting technique (T) consisting of a transplanter machine (T1), tile machines (T2), and manual (T3). Variety and planting techniques did not affect plant growth and productivity, but the variety had a significant effect on the average number of tillers, number of panicles, and plant productivity, with Inpari 32 variety showing the best results. Planting technique factors did not affect plant growth and productivity.
