Effect on grain yield and seed characteristics of leaf and tassel removal in dent and flint corn

The research was carried out with the aim to investigation the effects on grain yield and some seed characteristics of leaf, tassel removal and together treatments in maize during 2019 year. The experiments were set up according to a Randomized Complete Block Design in a split-plot arrangement with three replicates, where cultivars were in the main plots while the practices were in subplots within the main plots using Bora (dent corn) and Karadeniz Yıldızı (flint corn) maize cultivars. Effect on yield and seed characteristics of leaf (LR) and tassel removal (TR) and leaf x tassel removal interaction (LRxTR) were positive in both cultivars. The highest eat length 22.03 cm, ear diameter 53.89 cm, ear weight 352.31 g per ear, seed width 5.58 mm, seed length 10.21 mm, seed number per ear 669.6 number, 1000 grain weight 416.6 g, hectoliter weight 75.2 kg and grain yield 1334.8 kg da-1 were determined from the LRxTR interaction on dent corn in both years. However, YS+UA and UA treatments were included in the same statistical group. Generally, the lowest yield and seed characteristics were recorded in control treatment. The tassel removal treatment could be recommended due to its positive effects on yield and seed characteristics.
