The effects of three bagging treatments (Mogul 19 g m‑2, Mogul 30 g m‑2 and Tyvek) and two spraying programs (standard and deficit) on ripening, yield and quality components have been determined on 'Trakya Ilkeren', an early table grape cultivar. The whole clusters were taken into bags at berry set. The deficit spraying differs from standard program with unique spraying against to Lobesia botrana before blooming and one less spraying against to mildew diseases. The temperatures in the Mogul bags were higher than out of the bags while inside temperatures for Tyvek bags were close to the outside temperatures. The relative humidity in the bags was less than surrounding air the bags for all bag types while it was higher in the Tyvek bags than Mogul bags. Berry firmness decreased with all bagging treatments. The anthocyanin content of the grapes was higher at bagged clusters of 'Trakya İlkeren' and this trend more apparently for Mogul bags. The weight of the berries of 'Trakya İlkeren' increased with Mogul 19 g m‑2. Mogul 19 g m‑2 provided 5 days of earliness while 2-4 days for Mogul 30 g m‑2 according to control applications.
