Productivity indicators such as hypothetic yield, bunch weight, bunch diameter, bunch length, number of berries per bunch and qualitative indicators such as size and weight of juice, total soluble solids (TSS), total acidity, and TSS/acid ratio were measured. All productivity parameters indicated a significant increase in vines fertilized by HA compared with control vines in both 2014 and 2015. While no significant difference were noticed between control vines and fertilized vines with HA in all qualitative indicators in 2014, in the contrary happened in 2015 as TSS and TSS/acid ratio increased significantly by the application of HA respect to control. Moreover T3 was the best treatment between all treatments in both productivity and quality attributes. Therefore applying HA improved the productivity and quality of Superior seedless grape, and proved that it could be used as alternative organic N fertilization in the future, and we advice to apply it for four times as indicated in T3.
