Response of Corn to Small Amounts of Fertilizer Placed with the Seed: II. Summary of 22 Field Trials1

Abstract

Abstract

Fertilizer was banded with the seed of corn (Zea mays L.) at rates supplying 3.1, 5.4, and 2.5 g N, P, and per meter of row, respectively, in 22 field trials. Fertilizer with the seed delayed and reduced emergence in several trials. On the average, it increased the dry weight of 36-day-old plants 36%, decreased the time to silking by 1.2 days, decreased the ear moisture at harvest 1.2% and increased grain yield 2.9%. A significant yield decrease due to fertilizer with the seed was observed in two trials. Fertilizer with the seed reduced ear node height and, in two trials, plant height. The effect on lodging was variable.
