Effect of Biochar Produced from Paddy Husk and Coconut Frond on Soil Physical Properties and Productivity of Ginger in a Laterite Soil

The effect of biochar produced from paddy husk and coconut frond on soil physical properties yield ginger crop was studied in a laterite Kerala, India. treatments included (PHB) (CFB) each @ 10, 20 30 t ha-1 + NPK as per KAU package practices (KAU POP) recommendation, POP alone (30 FYM 75: 50: 50 kg ha-1) absolute control. recovery 50% that 40%. Physical the were significantly improved by application compared to application. Specific surface area (68.74 2.56 m2 g-1 respectively) water holding capacity (276.33 256.51% higher for PHB CFB whereas bulk density lower (0.27Mg m-3) than (0.35 Mg m-3). Biochar reduced density, increased stable aggregates soil. Plant height, rhizome spread, calculated towards interpreting direct influence growth ginger. All these parameters positively influenced incorporation at different rates. highest obtained (13964.2 which par with (13418.3 ha-1). From investigations, it can be concluded or along treatment considered economically viable
