Abstract:
An Experiment was conducted at Homeimeh search station in Aleppo, through 2021/2022 season to compare adding hydrogel and soluble fertilizers, and their effects on productivity characteristics of corn variety “Ghota 1”. Completely randomized block design was used with five treatments: (control without fertilizers, adding soluble fertilizer by 2 kg/donem, adding hydrogel by 1, 2 3 kg/donem). The fertilizers were added three times through season. Some morphological and yield component measured with analysis of seed content of NPK. Positive effects were showed when adding hydrogel by rising seed content of NPK comparing with traditional soluble fertilizer. There was an increasing of grain yield, biological yield and seed weight in earns by ratio: 4.8, 7.9, 7.5% when adding at same level (2 kg/donem), and by ratio: 7.7, 19.8, 15.2% when adding (3 kg/donem) respectively. These indicate to efficiency of hydrogel fertilizers to supply mineral elements to corn by high efficiency comparing with traditional fertilizers. And that reflects on improve morphological and productivity characteristics of corn.
Key Words: Hydrogel, NPK, Corn, Seed Content of Minerals, Grain Yield.
