Effect of FYM, Biofertilizers and Zinc on Potassium Uptake by Maize

A field experiment was conducted to study the effect of FYM, biofertilizers (Azotobacter and VAM) and zinc on potassium uptake by maize during two consecutive years of 2006-07 and 2007-08 at Instructional Farm, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur. Application of FYM, biofertilizers and zinc significantly increased potassium uptake by maize. Combined use of FYM and biofertilizers significantly increased potassium uptake by maize and combined use of FYM and Zn also significantly increased the potassium uptake by maize.
