Description
Farming & Cultivation Guide — Groundnut AgriBee 20
Complete step-by-step agronomic guide for optimal crop management, disease resistance, and premium produce quality.
🌾 Soil Preparation & Field Prep
Proper land preparation ensures uniform seedling emergence and robust root anchorage.
🌱 Ideal Soil Type & pH
Well-drained sandy loam to loamy soils with pH 6.0–7.5. Deep, friable soils with good internal drainage are ideal for peg penetration and pod development.
✨ Core Advantage
Light, well-aerated soil ensures rapid germination, healthy hypogeal growth, and unhindered peg insertion into the soil for pod setting.
- 1
Deep summer ploughing (25–30 cm) followed by 2–3 cross-harrowings to achieve fine tilth and eliminate hard pans.
- 2
Field leveling using laser leveling equipment where possible; prepare drainage channels in low-lying areas to prevent waterlogging.
- 3
Incorporate 10–15 tonnes/ha of well-decomposed FYM or farmyard compost during the last harrowing to improve soil structure and moisture retention.
- 4
Conduct soil testing prior to sowing; apply agricultural lime at 250–500 kg/ha if soil pH is below 5.5 to neutralize acidity and optimize nutrient availability.
🌱 Sowing Time & Method
Precise seed rate and spacing maximize light interception and canopy development.
| Parameter | Recommendation | Agronomic Importance |
|---|---|---|
| Sowing Window | June 15 – July 15 (Kharif) | October 15 – November 15 (Rabi) | Ensures adequate monsoon moisture during early growth and avoids terminal drought during pod filling |
| Seed Rate | 80–90 kg/ha (~35–40 kg/acre) for berial seed; 90–100 kg/ha for desi types | Maintains optimal plant population of ~15–18 plants/m² for maximum canopy coverage and pod set |
| Spacing | 60 cm (row-to-row) × 10–12 cm (plant-to-plant) | Provides adequate canopy spread, light interception, and air circulation for peg penetration and pod development |
| Sowing Depth | 5–7 cm in normal soils; up to 8 cm in sandy soils | Optimal depth ensures consistent soil moisture contact for uniform germination while allowing adequate coleoptile emergence |
💧 Irrigation & Water Management
Adequate moisture regulation supports strong vegetative and reproductive growth.
☀️ Water Requirement Profile
Groundnut AgriBee 20 exhibits moderate drought tolerance due to its deep taproot system. Total water requirement ranges from 450–550 mm over the crop cycle. Drip irrigation is highly compatible and recommended for water-use efficiency; operate drip at 7–10 day intervals during active growth, delivering 25–35 mm per event. Under drip, apply 60–70% of ETc (crop evapotranspiration) to conserve water without compromising peg formation.
🌦️ Moisture Management
In rainfed conditions, ensure sowing coincides with reliable soil moisture. Use mulching (straw or polyethylene) immediately after sowing to conserve residual soil moisture. Apply a single rescue irrigation at initial flowering (35–40 DAS) if dry spells occur during the critical pod initiation phase.
- ✓
First Irrigation: Apply 5–7 days after sowing if soil is dry at seeding depth; this ensures uniform germination and stand establishment.
- ✓
Vegetative Phase (20–40 DAS): Light irrigation every 10–12 days to support leaf area development and branching; avoid waterlogging which causes root rot.
- ✓
Critical Stage – Flowering & Peg Initiation (40–70 DAS): Maintain adequate soil moisture; this is the most sensitive phase. Stress during flowering reduces flower longevity and peg entry, directly affecting pod set.
- ✓
Pre-Harvest: Cease irrigation 15–20 days before harvest to allow pod maturation and reduce field mold incidence; dry soil conditions facilitate clean digging.
🧪 Fertilizer & Nutrition Management
Balanced crop nutrition supports robust plant structure and premium produce quality.
| Nutrient | Recommended Dose (per Acre) | Application Method & Timing |
|---|---|---|
| Nitrogen (N) | 20–25 kg/acre (50–60 kg/ha) | 50% basal at sowing + 50% top-dressing at 30 DAS during second weeding/earthing-up |
| Phosphorus (P2O5) | 40–50 kg/acre (100–125 kg/ha) | 100% basal application as DAP (Di-ammonium Phosphate) or SSP during final land preparation |
| Potash (K2O) | 30–40 kg/acre (75–100 kg/ha) | 100% basal; split only if soil test indicates high leaching potential in sandy soils |
🌿 Interculture & Weed Management
Timely weed control ensures optimal nutrient and moisture availability for crop seedlings.
-
1
First Weeding & Hoeing: Carry out at 15–20 days after sowing (DAS) using a hand hoe or cultivator. Remove all emerging weeds to eliminate competition during the critical early growth phase. Shallow cultivation (5 cm depth) avoids damage to developing nodules and shallow roots.
-
2
Second Weeding & Earthing-Up: Perform at 30–35 DAS. Earthing-up mounds soil around the base of plants, which supports peg penetration into the soil and prevents exposed pegs from drying out. This operation also incorporates residual weed pressure and improves soil aeration around the root zone.
-
3
Mulching Application: Apply straw mulch (2–3 tonnes/ha) immediately after second weeding to conserve soil moisture, suppress late-season weeds, and maintain favorable soil temperature for pod development. In drip-irrigated crops, use black polyethylene mulch to maximize weed suppression and soil moisture efficiency.
🛡️ Pest & Disease Management
Proactive crop monitoring and integrated management ensure healthy crop development.
🐛 Insect Pest Management
- Termites (Holotrichia spp.): Symptoms include wilting patches, cut seedlings at soil level, and hollowed stems. Control: Treat soil with Chlorpyriphos 20 EC at 5 ml/liter of water drench at 10–15 DAS around plant base, or apply Carbaryl 50 WP at 2.5 kg/acre mixed with sand and broadcast in furrows before sowing.
- Pod Borer (Helicoverpa armigera): Symptoms include feeding damage on flowers, young pods, and bore holes in developing seeds. Control: Install pheromone traps at 10 traps/acre. Spray Chlorantraniliprole 18.5 SC at 0.3 ml/liter or Spinetoram 11.7 EC at 0.5 ml/liter at first sign of infestation (35–45 DAS). Repeat at 10-day intervals if needed. Use NPV virus at 250 LE/acre as a biocontrol measure.
- Whitefly (Bemisia tabaci): Symptoms include yellowing of lower leaves, curling, sooty mold development, and stunted growth; also vectors. Control: Spray Imidacloprid 17.8 SL at 0.3 ml/liter or Thiamethoxam 25 WG at 0.2 g/liter at 25–30 DAS. Use yellow sticky traps at 5 traps/acre for monitoring and mass trapping.
🔬 Disease Control
- TLeaf Spot (Cercospora personata & Cercosporiopsis Personantha): Symptoms include small brown to black spots on leaves that coalesce, causing premature defoliation. Control: Spray Mancozeb 75 WP at 2.5 g/liter or Chlorothalonil 75 WP at 2 g/liter at 45 DAS and repeat at 15-day intervals. Ensure proper spacing for canopy ventilation.
- Early Leaf Spot (Cercospora arachidicola): Symptoms include circular brown spots with yellow halos on upper leaf surface; severe infection leads to defoliation and reduced pod fill. Control: Apply Tebuconazole 50 WP at 0.5 g/liter or Propiconazole 25 EC at 0.5 ml/liter at 40 DAS as preventive spray. Remove and destroy infected plant debris after harvest.
- Sclerotial Blight (Sclerotium rolfsii): Symptoms include water-soaked lesions on stems near soil level, white cottony mycelium, and small bullet-shaped sclerotia; causes plant wilting and pod rot in soil. Control: drench soil with Trichoderma viride suspension (10 g/liter) at the base of plants at 30 DAS. Avoid waterlogging and practice crop rotation with non-legume crops.
