Response of Maize (Zea mays L.) to Seed Priming with Zinc and Boron on nutrient content and their Uptake

Results: The data revealed that the highest contents of N, P and K in grains and stover of maize and their uptake by grains, stover and total uptake by maize crop was recorded under treatment T7 (Seed priming with 0.1% borax), which was at par with treatment T3 (Seed priming with 0.5% ZnSO4).The highest zinc content in grains and stover of maize was recorded under treatment T4 (Seed priming with 1% ZnSO4), which was at par with T3 (Seed priming with 0.5% ZnSO4). While, the boron content in grains and stover of maize was highest in T7 (Seed priming with 0.1% borax) and it was at par with T5 (Seed priming with 0.01% borax) and T6 (Seed priming with 0.05% borax). Whereas, total uptake of zinc by grains, stover was recorded by T3 (Seed priming with 0.5% ZnSO4), which was at par with T4 (Seed priming with 1% ZnSO4). While, total uptake of boron by grains, stover by maize crop was maximum in T7 (Seed priming with 0.1% borax), which was significantly superior to all treatments. However, the minimum content of all these nutrients in grains, stover and their uptake by grains, stover and total uptake by maize crop was found under treatment T1 (Absolute control).
