The study aimed to find out the feasibility and profitability of substituting half of the recommended fertilizer rate (120-60-60 kg NPK/ha) with two, four and six foliar fertilizer applications starting at tassel emergence using Crop Giant 15-30-30+ ME under conventional and conservation tillage systems. Results showed that plants applied with 100% RR recorded the tallest plants, biggest ears and heaviest grain and ear yield as compared to plants applied with 50% RR plus two, four or six foliar fertilizer application which performed comparably. Tillage system did not significantly affect the growth and yield of white corn except on the length of corn ear. White corn except on the length of corn ear production under conservation tillage growth 100% RR was the most profitable.
