Summary paddy package of practices
Round 1: The Basics of Rice Agronomy Identifying the scientific name and exact chromosome number of cultivated rice.Determining the critical mean temperature ranges required during the flowering, fertilization, and ripening stages.Identifying the maximum temperature threshold that negatively impacts grain filling.Pinpointing the ideal soil pH range for normal rice growth.
Round 2: Kerala’s Rice Seasons & GeographyIdentifying the "Rice Bowl" of Kerala.Matching rice growing seasons (Virippu, Mundakan, Puncha) to their common names (Autumn, Winter, Summer).Categorizing seasons based on their water sources (completely irrigation-dependent, completely monsoon-dependent, or reliant on retreating South West monsoons plus irrigation).Pinpointing the exact sowing and harvesting months for specific crops in Kuttanad (Puncha), general agroclimatic zones (Virippu), Pokkali soils (Oorumundakan), and identifying where the Nancha season is prevalent.
Round 3: Rice Variety ClassificationIdentifying varieties suited for specific conditions: upland/dry/rainfed, long-duration for terraced regions (Palliyals/Myals), and those specific to Kari, Pokkali, and Kaippad soils.Categorizing lists of specific varieties (e.g., Jaya, Jyothi, Makaram, Kunjukunju) by their crop duration (short, medium, long, or extra-short).
Round 4: Advanced Cultivation & Regional SuitabilityChoosing the right varieties for complex farming systems: late varieties for second crops, first/second crops for Onattukara coastal sands, crops for Poonthalpadam, and varieties suited for the Kootumundakan system.Identifying the ideal contingent variety used strictly for direct sowing after crop loss.
Round 5: Specific Traits & CharacteristicsMatching short-duration varieties to their unique agronomic traits: suitability for direct seeding vs. transplanting, specific region adaptations (Kole, Kuttanad, upland/modan), and pest/disease resistance (blight, blast, blue beetle, gall midge).Identifying varieties based on physical characteristics (purple pigmentation, white bran, red bran) and quality traits (cooking quality, non-lodging, semi-tall).Determining photo-insensitivity vs. photo-sensitivity in various varieties.Calculating exact seed dormancy periods (up to 1 month vs. three weeks) and pinpointing the exact crop duration in days for specific varieties like Jaya and Hraswa.
