BUNCHING ONION PRODUCTION GUIDE

As planting medium, use seeds or basal tillers. Use animal manure and rice hull for a 1 meter seedbed. Use rice hull on straw to be placed on top of the seedbed to control harmful organism.

Sow 4 kilos seeds. Line it in rows. Set it across the bed about 5 cm apart. Seed be placed thin and even for the purpose of controlling damping off. Cover it with compost (lightly). Mulch with rice straw. Maintain to have an adequate soil moisture for fast growth and development. Don't use water in excess of what is only required. Over-irrigation can damaged your planting seed. Protect seedbed from direct sunlight and heavy rain. The use of nylon net will do.

Prepare the land thoroughly. Plow it 2 times as well as harrow. A month before land preparation, placed 30 cm layer of rice hull over the area being used. Burn it about 2 weeks. Burnt rice hull will be incorporated during land preparation. The purpose is to improve soil texture. The burnt rice hull can reduce the presence of weeds and diseases.

Apply animal manure before the bed preparation. Make a 1 meter bed. Fertilize and mulch it with rice straw before doing the transplanting. Water the seedbed according to its requirements. Gently uproot seedlings to prevent damage to the root. Apply 7 bags of complete fertilizer as basal. Trim the top portion of the leaves. The purpose is to reduce transpiration. It can increase plant survival during the period of its growth. Transplant in seedbeds with a spacing of 15 cm. Use markers to have a proper distance. Plant deep enough to ensure survival. Protect the basal portion of the plant to avoid damage. Press the soil lightly. The root should be fully protected by the soil. Irrigate the area used according to its requirement before and after transplanting.

Apply 3 bags of urea (46-0-0) 3 weeks after transplanting. Repeat it 2 weeks if the fertility of the soil is still very low. During dry season, you have to irrigate daily. Adequate moisture can ensure to have a fast and desirable growth.

To prevent the presence of pests and diseases that can affect the growth of the plants, then do a proper irrigation method by regulating humidity into the planted area. Remove any debris left from previous cropping. Remove all infected leaves to avoid contamination to the whole field. It is better to do a crop rotation for greater effectiveness. Harvest the plants 3 months after planting.
