Effect of nitrogen levels and herbicides on major nutrients uptake and recovery by finger millet in sodic soil

Abstract

Finger millet is an essential diet on everyday intake. It’s the third most food crop among millets. It requires less water to produce the yield and is recommended as a tolerant crop for sodic soil. Hence, an experiment was conducted with application of various herbicides in combination as subplots and two nitrogen levels viz., 100% RDF and 125% N RDF in split plot design to study their individual effect and their interaction. The results showed that application of 125% N RDF, PE oxyfluorfen + EPOE bispyribac sodium and 125% N plus PE oxyfluorfen + EPOE bispyribac sodium recorded higher primary nutrients uptake. The utrients recovery was also arrived and found to be higher comparatively in pendimethalin plots. Results revealed that the application of pre- emergence and post emergence herbicides have higher recovery of N, P and K in finger millet due to the maintainenence of weed free condition for longer extent along with 125 % N level through boosting the crop growth and improving the nutrients absorption.
