  1. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 1 : How do operations of a farm affect quality? SEED TO SEED CYCLE

  2. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 2 : Selection of variety’s affect quality CONSIDERATIONS: RICE VARIETY SELECTION

  3. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 3 : Three requirements of good crop management REQUIREMENTS: GOOD CROP MANAGEMENT • Water Management • To manage water, fields must be level and bunds or levees maintained. Uniform water depth across the field will contribute to: • a more uniform crop • higher grain yields • consistent moisture content in the grain Building bunds.

  4. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 3 : Three requirements of good crop management REQUIREMENTS: GOOD CROP MANAGEMENT Nutrient Management The right application levels of suitable fertilizers for the variety and growing conditions is essential. Prudent application of nitrogen is essential to get an evenly maturing crop with full grain size and high protein levels. NOTE: Excessive or uneven application of nitrogen can stimulate late tiller production which results in heads on the main culm ripening a number of days faster than the tillers. This results in more immature and green heads as well as higher moisture content that increases the chance of fissuring and spoilage. Conversely insufficient nitrogen can lead to reduced grain size and protein content. Farmers using the Leaf Color Chart (LCC) for determining appropriate Nitrogen application.

  9. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 5 : The importance of clean paddy • Why is clean paddy rice important? • has a higher value than grain that is contaminated with straws, chaff, weed seeds, soil, rubbish, and other non-grain materials • improves the storability of grain • reduces price penalties at the time of milling • improves milling output and quality.

  10. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 5 : The importance of clean paddy WINNOWING CLEANING GRAIN MECHANICALLY Winnowing (100 kg to 3 tonnes per hour) is an important technique for cleaning grain at the farm level. If there is not enough wind, simple electric air fans can be used to separate lighter materials from the grain. A mechanical seed cleaner, capable of cleaning 10-30 tonnes per hour.

  11. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 6 : The correct moisture content for storage SUNDRYING Wet spots in the grain due to uneven drying or weed seeds can lead to off odors and discoloration of the grain.

  12. Course : Grain Quality Module 2 : Seed to Seed Quality Lesson 7 : The correct storage for paddy STORAGE METHODS Traditional Hermetic Farmers often store seed and grain in claypots or woven plastic bags. Grain stored under these conditions is often exposed to moisture fluctuation, insects and rodents. Recycled oil drums and PVC containers can be used as low-cost sealed storage devices for paddy seed and grain.
