1. Land:
- Plow land, manuring, raised beds, drainage theodat low option or not, should government land along the furrow tarpaulin cover, land use or cover along the edges bamboo canvas, tattoo instruments used tree holes and put distance regulations, which limit the weeds, pests and avoid wastage of fertilizers, ... bring high efficiency in production.
2. Cultivation:
- A packet of seeds 5 grams of about 1500 seeds, planting enough for 500-700 m2. Central to the wooden soil porous, sowing on 5-10 m2, soil treatment with Basudin 10H to ants, crickets and Benlate C, Copper B, preventive Rovral seedlings.
- Extraction of seedlings to plant into pots when the first true leaves (10-12 days after sowing), transplanted to the field when the plant has 5 leaves stage (21-25 days after sowing).
- Can be double or single row planting. Growing single row, double row 0,5x0,35 m, a density of about 17000-20000 plants / ha. Planting double rows, rows 60 cm, 60 cm between plants, the density is about 25,000 plants / ha.
3. Care:
3.1. Infuriate:
- Tomato F1 PEAR (VA71) strong growth and branching, need to rig the tree from falling, prevent fruit rot, easy care, long time left receivable, less infected fruit. 1-1.2 m high gantry, human-shaped diagonal. Where high tree to tree using nylon rope to tie it.
3.2. Pruning:
- Tomato F1 PEAR (VA71 finite growth, if left natural, tree branch buds stabbed multiple, dispersed nutrition, small fruit makes ephemeral. Sprigs should prune below the first flower cluster, leaving just the body axillary buds on main beam and the first flowers, so many flowers fruit set, fruit growing well, extending the harvest, increasing productivity.
3.3. Duty:
- Basal 15-20 tons of manure and 500-1000 kg lime / ha, chemical fertilizers applied in the table following recommendations:

Time 15, 30, 45 days after transplanting, add foliar spray should SUPERMES to increase fruit yield.
3.4. Pest control:
- Aphids, hoppers Viscosity: spray Supracide drugs, Polytrin, Sumibass, Sumicombi, ...
- Thrips: Early prevention and treatment need to have 3-5 children / tree leaves to prevent virus infection, should spray Regent, Confido, Lannate, Danitol. (Need combined adhesive spray in rainy season).
- Leafminer: Spray Ofunack, Trigard, Netoxin.
- Borer left: Regent therapy room, Polytrin, Karate, Sherzol, Pegasus.
- Blight Disease: Causes dead and rotten fruit seedlings, spray Anvilk, Validacin, Tilt, Monceren.
- Diseases caused by Pythium anemones, wilt Fisarium spread from land, to treat nematodes, crop rotation with wheat, corn (grown on land not planted tomatoes, peppers infected), irrigated with a solution against Bordeaux (green alum), Copper B, spray Champion, Kasai, Rovral, Foraxyl 35WP, Ridomil, Topsin RC 250 M. tomatoes quite resistant to this disease.
- Fresh Bacterial wilt: dead trees quickly, barely leaves yellow. Vascular system in the body turn brown. Residual bacteria in the soil, crop rotation should another, plowing dry soil, leaves avoid root injury when care. Irrigation with Copper B vaccine, Benlate C, spraying periodically Kasuran, Starner, Sasa.
- The disease early chlorosis (Alternaria solani fungus): circular spots on leaves, dark brown border, between brown, fire deadly disease on the body, where stem left. Early preventive spray with Daconil, Bavistin, Derosal, Carbenda, Tilt, pumper.
- Diseases caused by fungi Phitopthora infestans late chlorosis, defoliation old, spread quickly, lesions appear on the body of water mushy, brown, horizontal brittle. On the contrary, the fungus attacks all stages, the lesions dark green water duct. To prevent illness should periodically sprayed with Foraxyl 35WP, Mancozeb, Curzate, Aliette 7 days
