Abstract
Abstract
Field experiment was carried out during the 2018 growing season in the central Kut nursery located within the Kut district of the Wasit Province in Iraq, with four treatments and three replicates in a randomized complete block design (RCBD) to the response of maize to foliar application potassium irrigated by basin irrigation method. Foliar potassium spraying (K2O 43%) as follows; control (KO), 1000 (K1), 2000 (K2) and 3000 (K3) Mg.L−1. The study showed that there were substantial effects on the number of grains per row, the number of grains per ear, the grain yield, and the biological yield, with treatment K3 achieving the highest averages of (35.50, 554.5, 9.548 t. ha−1, and 25.97 t. ha−1) correspondingly. Although the weight of 500 grains and the harvest index were not significantly altered by treatment K2, while the number of rows per ear was (15.68), the number of rows per ear was.
