Rice Farming Guide From Seeds to Harvesting SEED SELECTION Used a variety that appropriate to the environment Resistant to insects pest, diseases, & abiotoc stresses (e.g. drought, flood) in the locality Have produced relatively & high yield in the adaptability trials Acceptable to farmers and demanded by local market LAND PREPARATION Clean and repair dikes and ditches Plow or rotovate the field 21-30 days before planting Harrow the field every 7 days after plowing Final-harrow and level the field using a wooden plank or tiller attached leveler CROP ESTABLISHMENT The crop should be planted synchronously after a rest period of at least 30 days to avoid overlapping incidences of insect pest and disease population The crops should be established in two different ways (transplanted and Direct Seeded) 1. TRANSPLANTED SEEDBED PREPARATION Follow the recommended seeding rate of 40kg/ha for inbred seeds and 1518kg/ha for Hybrid seeds Use 400 m2 seedbed area for 15- 40 kg seeds for Manual transplanting Method Use 250-300trays for Mechanical Transplanting Method Use compost or any fully decomposed organic materials such as carbonized rice hull or rice straw to help loosen the soil, making pulling of seedlings easier with less roots damage SEED SOAKING and INCUBATION Soak seeds in clean water for 12-24 hours Wash seeds before and after soaking Change soaking water every 5-6hours Incubate seeds at 30℃for 24-36 hours or until the roots emerges Keeps seeds moist and aerated SEED SOWING Sow seeds when the roots are starting to come out Sow the seeds uniformly TRANSPLANTING Transplant 18-21 days age of seedlings at 2-3 seedlings/hill for manual transplanting method Transplant 14-18 days age of seedlings for mechanical transplanting method Replant missing hills within 7 Days after transplanting (DAT) 2. DIRECT SEEDED RICE (DSR) Prepare the field by following the land preparation procedure of transplanting method Construct small canals (25cm wide and 5 cm deep) surrounding the field near the dikes and at the middle of field Follow the recommended seeding rate of 40-60kg/ha for row seeding and 60-80kg/ha for broadcast seeding Soak and Incubate the seeds by following the soaking and incubation procedure of transplanting method Use drum seeder or broadcast pre-germinated seeds evenly onto the field Sow extra pre-germinated seeds on the side of the field for replanting Replant bare patches within 10 Days after sowing (DAS) NUTRIENT MANAGEMENT Know and manage the nutrient requirement of the crops Visual observation of deficiency symptoms Results of nutrient diagnostic and decision support tools Other available information Example of Diagnostic and Decision Support Tools Leaf Color Chart (LCC)- Tools to assess the nitrogen status of the crop using a 4 color Rice Crop Manager Advisory Service (RCMAS)- An ICT-based platfrom for rapidly deploying improved and rice farming management technologies Know the right element, amount and timing of fertilizer application WATER MANAGEMENT Achieve 3-5 cm water depth every irrigation time from early tillering until 2 weeks before crop maturity or harvest Drain water or stop irrigation 1-2 weeks before harvest For medium textured soil or during dry season, drain 1 week before harvest For fine texture soil or during wet season, drain 2 weeks before harvest Practice Alternate Wetting and Drying (AWD) aided by observation well Beneits of AWD; Corretcs water use in irrigated lowland rice; Aids in proper seed germination and seedling survival, tillering and grain uniformity,promotes better soil nutrients, minimize golden apple snail attack; stabilize soil and plant base, helps minimize crop lodging and Reduces farm inputs such as oil and fuel and labor. PEST MANAGEMENT Use varieties that are resistant to pest and prevalent in the locality Using resistant varieties is the primary defense against pests. With a resistant host plant, very minor pest management activities are required. Practice synchronous planting after a 30-day rest period Planting within a month of the community's typical planting time helps decrease pest damage. It cuts off the pest's food supply and prevents the pest from multiplying further. Regularly check crops from early stages to identify potential pests. HARVEST MANAGEMENT Drain field 1 to 2 weeks before the expected date of harvesting Benefits: to attain uniform maturity and ripening, to prevent wetting of the grain during harvesting and to easy operation in the field Harvest at the right maturity, when 85-90% (manual) or 90-95% (combine harvester) of the grains are golden yellow Harvest at the right grain moisture content (MC)
