Effect of foliar nutrition on nutrient content and uptake by sweet corn (Zea mays L. Saccharata)

Abstract

A field experiment was conducted at the Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur during kharif, 2024 to study the effect of foliar nutrition on nutrient content and uptake by sweet corn (Zea mays L. saccharata). The experiment was laid out in a randomized block design comprised of nine foliar nutrition treatments that are replicated four times. Foliar application of 1% 19-19-19 NPK at 45 DAS + 1% KNO3 at 60 DAS (T6) recorded higher nutrient content and uptake that favours higher growth and productivity of sweet corn.
