The Effects on Yield and Quality of Applications in Different Doses of Humic Substance in Alphonse Lavallée Grape Cultivar

Abstract

This study was conducted 7 years old Alphonse Lavallée (Vitis vinifera L.) grape cultivar grafted on 1103 Paulsen rootstock in a vegetation period of 2018 in application area of Agriculture Faculty of Selcuk University in Konya province. In this research, it was investigated the effects of Dose 0 (Control) (0 ml TKI-Humas / 5 liter water), Dose 1 (167 ml TKI-Humas / 5 liter water), Dose 2 (333 ml TKI-Humas / 5 liter water), Dose 3 (500 ml TKI-Humas / 5 liter water), Dose 4 (667 ml TKI-Humas / 5 liter water) applications on grape yield and quality in Alphonse Lavallée grape cultivar. According to the findings obtained as the highest fresh grape yield 25.60 kg/vine with Dose 3; the highest cluster weight 678.14 g with Dose 3; the highest berry weight 8.30 g with Dose 3; the highest maturity index 33.62 with Dose 2 application. The effects of applications on L* color intensity, a* color intensity and b* color intensity values were not found statistically significant. To increase the fresh grape yield, cluster weight and berry weight can be recommended with Dose 3 application (500 ml TKI-Humas / 5 liter water) in Alphonse Lavallée grape cultivar.
