Response of Pea Plants to Spraying with Boron and Sugar Alcohol (mannitol) and Their Effect on Chemical Traits of the Crop

Abstract

Abstract The experiment was conducted at the Research Station of the Department of Horticulture, College of Agriculture-University of Diyala, during the autumn season 2021–2022 to study the effect of foliar application of mannitol with three concentrations of 0, 10, and 15 g. liter−1, and boron in four concentrations (0, 50, 100, and 150) mg. liter-1 on the chemical parameters of the pea yield. The foliar application spraying with mannitol 15 g.L−1 gave the highest mean in nitrogen, phosphorus, and protein (1.976%, 0.306%, and 7.040 mg), respectively. While spraying with boron at a concentration of 150 gm.L−1 was superior in recording the highest mean in nitrogen, phosphorus, potassium, boron, protein, carbohydrate, and total soluble solids, which reached (2.345, 0.391, 2.365, 54.44%, 8.451 mg, 14.59 mg, and 17.066%).
