The response of paddy with biochar application and legowo planting system at Tanjung Garbus Kampung Village

Abstract

Abstract A black charcoal from the heating of biomass with limited or without oxygen called Biochar. It is organic matter that has stable charateristics could be removed in dry land. The purpose of this study was to evaluate the response of biochar application on paddy fields and legowo planting systems. The Factorial Plan Split Plot Design was used for this research with two factors, namely; the treatment of planting system (main plot/S) with two stages, Jajar Legowo 2:1 and Jajar Legowo 4:1 and biochar’s application as sub-plot with three level; control, 25.5 ton/ha, and 50.5 ton/ha. The research was carried out in Tanjung Garbus Kampung’s Village, Pagar Merbau Sub-district, Deli Serdang Regency with an elevation of ± 50 Meters above sea level. The paddy field has irrigation system for watering the crops. The biochar application and legowo planting system showed a slight significant effect on the root volume. However, the application of biochar and legowo planting systems statistically unaffected on the weight of 1000 grains of paddy crops. Therefore, legowo planting system had slight difference on the production per hectare for paddy.
