00Quick Start & OverviewGinger farming quick-start: why drainage, seed health and shade decide profit, the ten-commandment management summary, and how to use this compendium. 01Botany & Plant AnatomyZingiber officinale anatomy: rhizome, pseudostem, shallow roots and growth phases from sprouting to maturation, plus the gingerol chemistry that sets ginger's price. 02Varieties & SelectionCompare Chinese young, Jamaican, Nigerian/African, Maran, IISR releases and Rio-de-Janeiro ginger for fresh, dried or extract markets — plus the variety selection checklist and matching wizard. 03Climate & MicroclimateGinger's climatic envelope: optimum temperature, rainfall and light, how to design 25–50% shade, and the two failure modes of too much or too little water. 04Soils, pH & Bed DesignWhat ginger wants from soil texture, pH and drainage; raised bed vs ridge vs slope systems compared; reading a soil test for ginger; pre-plant solarization. 05Seed Rhizomes & PropagationSeed is 40–50% of ginger's variable cost: grading seed pieces, seed rates, the standard fungicide-plus-Trichoderma treatment, and running a nucleus multiplication plot. 06Land Prep & PlantingGinger land preparation step by step: tillage, bed forming and drainage first, then planting depth, spacing, orientation and the two-round mulching program. 07The Crop CalendarA DAP-keyed field calendar for tropical ginger from pre-plant to harvest, with the two hardest weeks and a link to the printable weekly field checklist. 08Irrigation & Water ManagementIrrigation methods compared (drip, sprinkler, furrow, hand), schedules by growth stage, drainage as irrigation, and a 24-hour standing-water emergency rule. 09Nutrition & Fertilizer ManagementReference N-P-K schedules for ginger (IISR/Kerala packages), nutrient-by-nutrient field notes, application hygiene, and the interactive fertilizer bag calculator. 10Pest ManagementGinger's major pests: shoot borer, rhizome scale and nematodes — identification, thresholds and the integrated IPM spine, from weekly scouting to spot treatments. 11Disease ManagementSoft rot (Pythium complex), bacterial wilt and yellow disease: recognition, epidemiology, and prevention-first integrated management from treated seed to roguing and drains. 12Harvest & CuringGreen vs mature vs dry-ginger harvest windows, careful lifting, and the wash-peel-dry-polish curing line with dried-ginger trade grades and recovery math. 13Processing & Value AdditionFrom farm gate to extract: dried ginger, powder, volatile oil and oleoresin yields, candied and pickled ginger, grading discipline, and certification ladders. 14Economics & MarketsA representative smallholder budget for 1 ha of ginger, price seasonality and fresh-vs-dried arbitrage, and the honest risk register with mitigations. 15Organic & Low-Input GingerOrganic and low-input ginger: certification demands, building fertility with compost, neem and green manure, and managing pests and disease without synthetic tools. 16Post-Harvest, Storage & Export QualityField-to-store handling, fresh-ginger storage options, the export quality ledger (residues, moisture, recovery) and the storage house that saves the margin. WThe First 90 DaysA guided six-phase sequence chaining Chapters 04–08 and the online tools: foundations, seed and beds, planting, emergence, first topdress and the switch to scouting — with a planting-date phase tracker. 17ToolkitGinger lookup toolkit: units and conversions, symptom-to-action troubleshooting matrix, FAQ and glossary. §References & Further ReadingSources for the compendium: IISR and KAU bulletins, Spices Board specifications, NABARD cost models, Ravindran & Nirmal Babu, and FAO tropical manuals. ⚙Online ToolsEight calculators and field aids: seed, spray-mix, revenue, drip, liming, budget, plus the fertilizer and variety tools.
