Abstract

In the present study, a field experiment was conducted in a FRBD with three (3) replications comprising four (4) foliar application of nanofertilizer (F1: Control; F2: at knee high stage; F3: at 50% tasseling stage and F4: both at knee high stage + at 50% tasseling stage) and four fertility levels (F1: 100% RDF; F2: 90% RDF; F3:80% RDF & F4: control) to study the effect of foliar application of zinc based nanofertilizer and varying fertility levels on nutrient concentration and accumulation of nutrients along with of maize in Southern Rajasthan. Nitrogen content (1.782 %, 1.760%), phosphorus content (0.391%, 0.403%) and zinc content (63.76 ppm, 67.11 ppm) of maize grain and nitrogen content (0.798 %, 0.793%), phosphorus content (0.182%, 0.173%) and zinc content (66.78 ppm, 70.40 ppm) of maize stover increased significantly by the foliar application zinc based nanofertilizer at dual stage viz., at knee high stage and at 50 per cent tasseling stage as compared to single stage application and application of 90 per cent RDF in maize, respectively. Similarly, foliar application zinc based nanofertilizer at dual stage viz., at knee high stage & at 50 per cent tasseling stage and 90 % RDF in maize had significant effect on nutrient accumulation by grain and stover of maize.

Conclusion

The present study’s finding indicates that foliar application of 0.1% zinc based nanofertilizer at knee high stage and 50 per cent tasseling stage significantly enhanced the nutrient concentration and accumulation of maize. Further, application of 90 per cent recommended dose of fertilizer had statistically significant influenced nutrient concentration and accumulation of maize.
