Organic potato production – The biodynamic way

Field experiments were conducted in Typical Ustochrept soil of Modipuram from 2002–03 to 2004–05 to produce organic potato, following principles of biodynamic farming. In the first year, the highest tuber yield (190.7 q ha⁻¹) was obtained in Kufri Anand followed by Kufri Sutlej (173.5 q ha⁻¹). In case of Kufri Chipsona-1, Kufri Bahar, Kufri Pukhraj and Kufri Chipsona-2, the aggregate tuber yields were 155.2, 152.6, 136.0 and 120.4 q ha⁻¹, respectively. The continuous raising of organic potato bio-dynamically on the same site, improved tuber production by 30–50%. A perusal of grade-wise tuber production revealed that bio-dynamically raised organic potato produced 8–11% more seed size tubers than inorganically fertilized crop.
