BIOFERTILIZER OPTIONS IN NUTRIENT MANAGEMENT OF POTATO

S. N. Dash, R. C. Jena

Abstract :

High dose of fertilizers raises the cost of cultivation of potato. An experiment was conducted at the Orissa University of Agriculture and Technology, Bhubaneswar during rabi seasons of 2012-13 and 2013-14. Use of biofertilizers

was evaluated as an option in nutrient management for studying growth, yield, nutrient uptake and economics of potato cv. KufriChandramukhi. The yield (28.98 t ha-1) and uptake of nutrients (94.4 kg N ha-1 and 17.1 kg P ha-1) of a crop raised from seed tubers soaked in 1%
each of urea and NaHCO3 and biofertilizer treatment (Azotobacter+phosphorus solubilizing bacteria) under 75% of recommended NP was
significantly higher than that from 100% nutrients from inorganic sources. It also resulted in maximum net return (`55186) and return per
rupee investment (2.03) indicating 25% saving of NP over full nutrient application through inorganic sources.
