1– Prepare root-stocks cuttings end of December at 35 cm long having 4 buds and remove the bottom three buds then leave the top bud without removal. Store and keep quite irrigation to prevent cuttings drying and enhance callusing and rooting. 3– In February; plant the rooted cuttings directly on flat land beside the irrigation hose, 7 cm apart and 20 cm deep, this distance give us around 57000 root-stocks per Feddan. Tow months after planting; fertilization will start from May to September, apply total of 25 Kg of Nitrogen + 10 kg Phosphorus + 20 kg potassium + 7 kg Calcium + 2 kg Magnesium per Feddan. Keep the root-stocks healthy overall the season by follow a suitable pests control program for your region, in TOSHKA region we spray against flower trips, red mites and powdery mildew all the season.
7– The vines are ready to pullout next February to sell or plant them directly in the field, More than 90 % success by expert grafters hand have been gained, in the end you can catch more than 40000 grafted vines ready to sell or plant in field, by using a good manufactured U shape pulling out machine hanged on compact small tractor.
4– In the same year in August we start Chip budding method by collect the scions from the recent season mature grapevines to graft in the open field, and then graft in same time. One or tow days before grafting, prepare the root-stocks for budding by make suckering and cut all the growth 40 cm above ground, then apply deep irrigation. Then next day with a sharpened knife cut and put the chip bud; 5 cm above ground and before the first shoot, tie with elastic budding tape, cover after tying directly with white paper. Seven days after budding cut the top third of root stock growth. Ten days after budding a lot of suckers appear above grafted buds, start to remove these suckers immediately and cut the second third of growth.
5- Tow weeks after budding cut the growth completely 5 cm above the grafted buds, at this time you can check callusing under plastic tapes, and some buds start to grow in the same month. Continue sucker around buds till it has 2 opened true leaves, then you can remove the paper-(in our hot/dry region like TOSHKA don't attempt to remove the paper at green balloon stage, it will die) - and cut directly 2 cm above grafted buds. It takes around 45 days to complete the callusing process, then the new wood start to mature within the vine to be a new tree after 120 days from grafting date.
6– When the variety shoots arrive to 15 cm long after budding success, tip them in order to enhance laterals growing, try to keep the variety height not more than 25 long to prevent buds breaking from union and enhance shoots maturation during autumn. With using a special elastic Para film and treated tape for tying after budding you don't need to cut the tape, the callus and wood will be initiated within that tape during autumn and winter.
7– The vines are ready to pullout next February to sell or plant them directly in the field, More than 90 % success by expert grafters hand have been gained, in the end you can catch more than 40000 grafted vines ready to sell or plant in field, by using a good manufactured U shape pulling out machine hanged on compact small tractor.
This technique has been established for dry hot region in Egypt south valley project (TOSHKA Project).
2– Prepare the open field land in January for planting; Rip and prepare the soil then apply 5 cubic meter compost + 200 kg super phosphate + 5 tons Gypsum per Feddan ( 0.42 Hectare ), then fining and elevate the soil, then establish irrigation hoses 1 meters apart to plant in the end of February.
