The Effects of Biochar and Chicken Manure Application on Red Ginger (Zingiber Officinale Rosc.) Growth and Yield of Semi Paludiculture in Tropical Peatlands

Abstract

The research was conducted to determine the influence of growth and yield of red ginger plants by applying the combination of biochar palm oil and chicken manure in a semi-paludiculture planting system on peatland. The design used in this study is the Completely Randomized Design (CRD) with 4x4 factors and with a three repetitions factor. The first treatment factors are oil palm shell biochar with control treatment, 5 t ha^-1, 10 t ha^-1 and 15 t ha^-1 and the second factor is chicken manure with control treatment, 5 t ha^-1, 10 t ha^-1 and 15 t ha^-1. The research was conducted in Tanjung Taruna Village, Jabiren Raya Sub-district, Pulang Pisau Regency. The research was conducted from December 2018 until April 2019. The results showed that the interaction occurred in both factors, on the plant variable's height and the highest yield from the introduction of chicken manure 10 t ha^-1 and the biochar 15 t ha^-1. The interaction of biochar palm oil shells on growth and yield of ginger plants only occur in plant variable height and the samplings at 8, 10, and 14 weeks after planting. While the chicken manure has real effect on ginger plants' growth and yield in all observation variables.
