Abstract

The aim of the current investigation was to determine if maize had the ability to assimilate macronutrients under the effect of humic substance that was enriched with micronutrients. A field experiment was conducted with 10 treatments replicated thrice using RCBD this in the College of Agriculture's V C Farm in Mandya, Karnataka, India during Kharif 2017. The findings showed that the treatment getting RDF + FYM @ 10 t ha-1 together with Enriched HS @ 5 L ha-1 30 DAS had substantially greater macronutrient content and absorption in grains and stover than the treatment receiving RDF + FYM @ 10 t ha-1 along with Enriched HS @ 2.5 L ha-1 30 DAS. Whereas lower macronutrients content was recorded for the treatment with RDF alone. Among different treatments, T10 treatment (T2 + Enriched HS @ 5 L ha-1 30 DAS) recorded significantly higher total uptake of N, P, K, Ca, Mg and S (225.30, 58.44, 91.03, 96.04, 60.86 and 59.47 kg ha-1, respectively). Whereas lower N, P, K, Ca, Mg and S uptake (141.90, 26.94, 40.28, 46.24, 22.37 and 22.27 kg ha-1, respectively) were recorded for the treatment with RDF alone (T1).
