Abstract
Afield experiment was carried on the autumn season 2020. D in the field of on the farmer mazraea village of Baiji district Saladin governorate to find out the effect of three concentrations of glutamic amino acid were (0, 150, and 200 mg/ L) and three planting distance (10, 20, and 30)cm between hills in growth, yield and quality of two Sweet corn which are Arma and Soleil. Factorial arrangement was used to Randomized complete block design with three. The results indicated that Arma cultivar was superior in 75% tassling and silking of plants (56.74, and 64.33%) respectively, while the Soliel cultivar was superior in protein percentage trait (5.55% ) .The planting distance 30 cm between hills is superior of traits number of ears (1.14 arnos.plant-1and 60.33 grain) ear. Plant and grain 300 weight. The concentration of glutamic amino acid 200m.L-1superior of traits number of ear, grain 300 weight, single plant yield and protein and carbohydrates percentage (1.17 arnus.plant-1, 332.33arnus-1, 63.11grains,102.77g.plant-1, 5.69 and 9.18%) respectively. The interaction treatment the variety Arma and planting distance 20cm superior in single plant yield g.plant-1 (120.77 g.plant-1). The combination treatment the variety Soleil and planting distance 20cm were superior of protein and carbohydrates percentage traits ( 6.14 and 10.21%) respectively , The best intervention is to treat 200 ml of Glutamic with a distance of 30 cm and it gave the best results
