We studied the role of addition of various organic supplements for zinc uptake and
overall maize crop performance. In field experiment, different sources of organic
matter were added as supplement doses in the form of compost, biochar, humic acid
and biofertilizer with or without soil zinc application. All other agronomic practices
were remained normal as per farming community recommendation. Results revealed
that various organic supplements significantly improved the crop performance not
under zinc applied soil while also under zinc deficient soil. Crop showed accelerated
growth in term of leaf area index, leaf area duration, crop growth rate etc which
further leads toward better crop yield and quality. Organic supplements
(biochar>compost>humic acid>biofertilizer) improve the crop production in zinc
deficient as well as in zinc fertile soil but this effect was most prominent under
biochar application. Findings suggest that farmers can enhance the maize crop
productivity with the addition of organic supplements under zinc fertilization.
