Abstract


A field experiment was conducted during 2010-11 and 2011-12 at Indian Agriculture Research Institute, New Delhi to study the productivity and profitability of application of different source of potassium in maize wheat cropping system. The experiment was laid out in Randomized Block Design consists of ten treatments and replicated thrice. Results revealed that potassium application irrespective of sources was superior over control. Application of 60 kg K through muriate of potash + 30 kg K through farmyard manure in both maize and wheat resulted into higher yield attributes, grain yield and nutrient concentration. This treatment was closely followed by 30 kg K through muriate of potash + 30 kg K through farmyard manure in both maize and wheat which was found significantly superior over 60 kg K through muriate of potash alone and treatment without potassium application.
