Fertilizer-Prescription Equations for Targeted Yield in Radish under Integrated Nutrient Management System

Soil test crop response correlation studies under integrated plant nutrient system were carried out in Inceptisol of West Bengal during 2008 - 2010, with radish as a test crop following Ramamoorthy's 'inductive-cum-targeted yield model'. Four fertilizer (NPK) and three farmyard manure...
