Abstract
To combat with the adverse effect of Zn deficiency, a field experiment was carried out at instructional-cum-research farm of Assam Agricultural University, Jorhat, Assam during 2020–22 with 10 different treatments with both soil- and foliar-applied zinc laid on RBD. Result revealed substantial improvement in cob yield and quality of maize due to supplementation of both soil and foliar zinc. The addition of Zn @ 2.5 kg ha−1 and 0.5% foliar Zn at critical stages substantially increased 47.35% higher cob yield than without Zn supplementation. The combined application significantly increased the nutrient content and uptake and registered 35.42 and 110.61% more Zn content over control and substantially its uptake by grain. Considerable improvement in quality of maize was also noted due to the addition of Zn @ 2.5 kg ha−1 and 0.5% foliar-applied Zn. The supplementation of both soil- and foliar-applied zinc also optimized the crude as well as soluble protein of grain than without Zn besides improving the post-harvest nutrients of soil, PFP of N, P, and K including zinc mobilization efficiency index. The foliar-applied Zn was more effective in enhancing ZUE as compared to soil and their combined application. Comprehensively, the supplementation of both Zn @ 2.5 kg ha−1 and 0.5% foliar-applied Zn is found to be economically profitable over all other doses. The nutrient uptake by plants showed a positive impact in improving yield and quality of maize and each one increase uptake in N, P, K, Zn showed an increase in cob yield by 0.145, 1.029, 0.456, and 0.111, respectively. Similarly, N and Zn content in grain showed strong relationship for enhancing protein content of maize. Hence, the combined application of Zn @ 2.5 kg ha−1 and 0.5% foliar-applied Zn at critical stages may be recommended in Zinc-deficient acidic soil of India.
