Abstract
Nowadays, growing sweet maize is difficult due to increasing climate change. This research was carried out under irrigated and non-irrigated conditions at the University of Debrecen, Böszörményi út Campus Demonstration Garden. The examined sweet maize hybrids were SF1379 and Honey. Precision instruments were used to monitor the development of the sweet maize population. Leaf area index (LAI), SPAD values and Normalized Differential Vegetation Index (NDVI) were measured in two phenological stages. The evolution of dry matter production of husk, cob and grain was measured before and at harvest. The obtained experiment results showed that LAI, SPAD, NDVI and dry matter values increased significantly with irrigation.
We can provide practical results for sweet maize growers to raise awareness on the use of precision irrigation. Sweet maize production requires optimal, precise technology and is efficient and profitable under irrigated conditions.
