Key Features

Climate and Soil Requirements

• Finger millet grows well in temperatures between 18–32°C, with annual rainfall of 400–1000 mm.
• Performs best in well-drained red, loamy, or sandy soils, pH between 5.5 and 7.5.
• Suitable for marginal, less fertile soils and rainfed uplands where many cereals cannot survive.
• Tolerates some soil acidity but avoids waterlogged and saline soils which reduce grain yield.
• Needs good seedbed preparation for strong root growth and early weed suppression.
• Mulching conserves moisture and keeps the soil cool in hot climates.
• Fields should have gentle slopes for good drainage, avoiding low-lying flood-prone areas.
• Soil with moderate organic matter supports healthy growth and better nutrient use.
• Prior green manure or legume crops improve soil structure and available nitrogen.

Land Preparation

• Plough field 2–3 times and harrow to achieve a fine tilth for easy seeding and weed control.
• Remove all weeds, crop residues, stones, and lumps for even germination and growth.
• Farmyard manure or compost (5–10 tons/ha) should be mixed in before sowing for fertility.
• Create beds, ridges, or flat plots based on rainfall and drainage; beds suit high rainfall, ridges for dry zones.
• Level land for uniform irrigation and easier intercultural operation.
• Prepare the field well in advance for timely sowing at the start of monsoon.
• Mark rows with rope or marker sticks for precise planting and plant stand.
• Use laser leveling if available for large fields to save water and nutrients.
• Keep boundary bunds strong to minimize soil erosion and nutrient run-off.

High-Yielding and Hybrid Seed Selection

• Use improved varieties like GPU 28, Indaf-5, KMR-204, or local recommended hybrids for high yields.
• Always purchase certified seeds with a high germination rate from verified sources.
• Select short-duration varieties for rainfed/dryland and long-duration for irrigated conditions.
• Small, uniform, healthy and disease-free seeds promote strong, uniform stands.
• Breeder seeds should be multiplied in small plots before full-field use if in doubt.
• Mix multiple varieties for climate resilience only if recommended by experts.
• Store seeds in airtight, moisture-free containers to protect from pests.
• Test seed germination before sowing using a small home test.
• Maintain records for each seed lot used for field tracking.

Seed Treatment

• Treat seeds with Trichoderma, bavistin, or thiram to prevent seed-borne fungal diseases and boost survival.
• Optional soaking of seeds in water for 6–8 hours can speed early sprouting and boost establishment.
• Seed pelleting with micronutrients (Zn/Fe) can be done for poor soils to ensure nutrition at start.
• Sun-dry seeds briefly after treatment to avoid clumping during sowing.
• Use bio-fungicide dips or biolife seed coating for organic farming.
• Do not mix treated seed with untreated or food grain for safety.
• Ensure seed rate is accurate post-treatment – about 8–10 kg seed/ha traditional or 5 kg/ha for line sowing.
• Clean all sowing tools to avoid cross-contamination.
• Clearly mark treated batches to avoid mixups at sowing time.

Sowing and Planting Methods

• Direct broadcast or line sowing at onset of monsoon is common for ragi; use row spacings of 22.5–30 cm.
• Transplanting seedlings (18–22 days old) boosts yield and uniformity, especially in irrigated areas.
• Maintain plant spacing of 8–10 cm within rows for optimum tillering and grain size.
• Use ferti-seed drills for uniform seeds and fertilizer placement.
• Avoid sowing in standing water or before major rains to reduce seed rot.
• Mulch lightly after sowing to conserve moisture and reduce weeds.
• Fill in gaps by re-seeding within 15 days to avoid crop stand loss.
• Intercrop ragi with short pulses for weed control and higher profit.
• Tag planting dates, varieties, and plot layout for field management.

Nutrient and Fertilizer Management

• Add 5–10 tons/ha FYM or compost, then apply fertilizers as per soil test or standard dose (40–60 kg N, 20–30 kg P2O5, 20–30 kg K2O/ha).
• Split nitrogen dose: half at sowing, rest at tillering and ear head stages for best results.
• Foliar sprays of micronutrients (zinc, iron, boron) help in deficient soils and boost yield.
• Green manure or biofertilizer (Rhizobacteria, Azospirillum) improves soil life.
• Avoid excess N as it promotes leafy growth and reduces grain filling.
• Apply fertilizer in bands 5 cm to the side of the seed row – not directly with seed to prevent burn.
• Top-dress after rains in dryland to avoid nutrient leaching.
• Maintain detailed fertilizer and yield records for planning next seasons.
• Organic farming is possible – use enriched composts and natural sprays.

Irrigation and Water Management

• Rainfed crops often need only life-saving irrigation at major spells of drought.
• Where available, one irrigation at tillering and another at flowering/booting increases yield.
• Avoid overwatering and waterlogging; ragi is drought-tolerant but sensitive to poor drainage.
• Use furrow or sprinkler irrigation as per available water supply, avoid flooding methods.
• Mulch and intercropping reduce soil evaporation and need for supplementary irrigation.
• Monitor soil moisture (by hand or probes) to schedule watering efficiently.
• Install farm ponds for harvesting excess rainwater for supplementary irrigation.
• Drain excess water promptly after heavy rains to protect roots.
• Maintain field bunds, cracks, and leaks for water efficiency.

Intercultural Operations

• Start weeding 15 days after sowing, repeat 2–3 times as needed for clean, healthy plants.
• Early thinnings (at 8–10 cm plant spacing) give better tillers and help root growth.
• Light hoeing or inter-cultivation aerates the soil and reduces weed seedling growth.
• Avoid deep hoeing to protect shallow ragi roots.
• Intercrop with short-duration pulses and green manures for pest, weed, and nitrogen control.
• Remove diseased or stunted plants quickly to avoid spread.
• Practice earthing up if needed in sandy soils to strengthen plants.
• Maintain field hygiene – remove crop trash, weeds, and debris regularly.
• Train labor in correct hoeing and weeding for better crop results.

Pest Management

• Ragi is mostly pest-resistant. Key pests: ragi pink borer, shoot fly, aphids, and armyworm.
• Monitor fields regularly and use pest traps or manual picking for control.
• Opt for neem oil sprays or bioinsecticides to control major pests.
• Crop rotation with pulses and regular field sanitation reduce major pests.
• Use light traps for night pests and encourage natural enemies (ladybugs, parasitoids).
• Only use chemical pesticides if population thresholds are crossed – targeted, not blanket sprays.
• Avoid spraying when grain is in the milky stage to protect food safety.
• Remove and destroy pest-affected plants and trash promptly.
• Keep grazing animals out to prevent accidental spread of pests.

Disease Management

• Main diseases: blast, leaf spot, rust, and smut.
• Use certified, disease-free seed and resistant varieties for best prevention.
• Apply seed treatment and maintain field cleanliness for early defense.
• Rogue out (remove) and destroy diseased patches at first sign.
• Apply recommended fungicides or bio-control agents if needed.
• Crop rotation and good spacing reduce fungal and bacterial risks.
• Avoid overhead irrigation, which raises humidity and leaf disease rates.
• Record all disease sightings and treatments for future reference.
• Use proper personal protection and tool cleanliness in infected fields.

Harvesting and Post-Harvest Management

• Harvest when finger millet ear heads turn brown and grain is hard – usually 3.5–4 months after sowing.
• Cut ear heads and dry in sun before manual threshing to separate grains.
• Store grain in clean, dry, airtight containers to prevent mold and pest attack.
• Grade and clean properly for market or home mill use; sun-dry if needed.
• Secure straw for animal feed or compost after harvest for complete value.
• Remove left-over stubble and clear fields for the next crop cycle.
• Avoid delays in harvesting to prevent shattering and grain loss.
• Market immediately or as price improves post-harvest.
• Keep track of yield, loss, and price for next season’s planning.
