Increased yield and nutrient uptake of several rice lines by applying soil amendments to newly cultivated land

Abstract

The objective of this study was to determine the effect of soil amendments and rice line on agronomic characters and nutrient uptake. The research was conducted in Bueng Tujoh (5o.50′5′14″N 95o47′67′36″ E), Atong village, Montasik sub-district, Aceh Besar district, from August to December 2021. This study used 3×6 factorial randomized block design with 3 replicates, consisting of 2 levels. There were 18 treatment combinations with 54 experimental plots. The main factors are three levels of soil enhancers consisting of A0 without soil amendments, A1 using biochar (20 t ha-1 or 4,8 kg plot-1), and A2 using manure (20 t ha-1 or 4,8 kg plot-1). The second factor was the rice lines which consisted of 6 lines: L1 (Inpari 42), L2 (C3), L3 (TG IRBB 27), L4 (15 E 1009), L5 (F1 C4 x KH), and L6 (Sigupai). The results showed that there are interactions between soil amendments and rice lines on parameters observed. The highest yield potential was found in Inpari 42 (4.92 t ha-1).
