- 1
Deep summer ploughing followed by 2–3 cross-harrowings for fine tilth.
- 2
Field leveling and drainage preparation to avoid water stagnation.
- 3
Incorporate well-decomposed FYM or compost @ 5–8 t/acre as basal manure.
- 4
Apply gypsum or sulfur where needed to balance alkaline/salty soils.
🌱 વાવણીનો સમય અને પદ્ધતિ
Precise seed rate and spacing maximize light interception and canopy development.
| માપદંડ / પેરામીટર | ભલામણ / સૂચના | કૃષિ મહત્વ |
|---|---|---|
| વાવણી સમયમર્યાદા | June–July for Kharif; Oct–Nov for Rabi; Feb–Mar for Zaid | Aligns temperature within 20–30°C range for optimal germination and growth |
| બિયારણનો દર (એકર દીઠ) | 2 kg per acre | Ensures uniform plant population and canopy coverage |
| હાર અને છોડ વચ્ચેનું અંતર | 60 cm x 10 cm (row-to-row x plant-to-plant) | Promotes adequate light penetration and airflow for healthy flower development |
| વાવણીની ઊંડાઈ | 2–3 cm | Ensures consistent emergence without excessive seedling energy expenditure |
💧 પિયત અને પાણી વ્યવસ્થાપન
Adequate moisture regulation supports strong vegetative and reproductive growth.
☀️ પાણીની જરૂરિયાત અને પિયત પ્રોફાઇલ
Sunflower Sunfarm exhibits moderate drought tolerance due to its deep taproot system. However, adequate soil moisture during flowering and grain filling significantly enhances seed filling and oil quality.
🌦️ Soil ભેજ વ્યવસ્થાપન
In rainfed areas, sow at the onset of reliable monsoon rainfall. Use mulching to conserve soil moisture and reduce evaporation during hot, dry spells.
- ✓
First irrigation at 20–25 days after sowing (DAS) to support initial root and vegetative growth.
- ✓
Maintain light irrigation every 10–15 days during the vegetative phase depending on soil texture and rainfall.
- ✓
Critical irrigation at 50–60 DAS during budding and flowering; ensure consistent moisture to prevent pollination failure.
- ✓
Reduce irrigation frequency from 80 DAS onward; cease watering completely 10–12 days before harvest to facilitate drying and prevent seed rot.
🧪 ખાતર અને પોષણ વ્યવસ્થાપન
Balanced crop nutrition supports robust plant structure and premium produce quality.
| પોષક તત્વ | ભલામણ કરેલ માત્રા (એકર દીઠ) | ઉપયોગ પદ્ધતિ અને સમય |
|---|---|---|
| નાઇટ્રોજન (N) | 40–50 kg/acre | 50% basal at sowing, 50% top-dressed at 30 DAS |
| ફોસ્ફરસ (P2O5) | 40–50 kg/acre | 100% basal with DAP or single-superphosphate at sowing |
| પોટાશ (K2O) | 20–30 kg/acre | 100% basal with MOP to strengthen stalk and improve seed oil content |
🌿 નિંદામણ નિયંત્રણ અને આંતરખેડ
Timely weed control ensures optimal nutrient and moisture availability for crop seedlings.
-
1
પ્રથમ નિંદામણ અને ગોડ: Carry out at 15–20 DAS to remove early weed competition and loosen soil surface for aeration.
-
2
બીજી વાવણી અને પાળા ચઢાવવા: Perform at 30–35 DAS to control later weeds and mound soil around stems for improved root anchorage.
-
3
Inter-row Hoeing & Mulching: Mulch with straw or green leaves between rows to conserve moisture, suppress weeds, and moderate soil temperature.
🛡️ જીવાત અને રોગ નિયંત્રણ
Proactive crop monitoring and integrated management ensure healthy crop development.
🐛 જીવાત નિયંત્રણ અને સંરક્ષણ
- Sunflower Head Caterpillar: Symptoms include bore holes in flower heads and frass accumulation. Control: Spray Endosulfan 4% dust @ 15 kg/acre or recommend Trichogramma releases at 50,000/acre weekly from branching stage.
- Shoot Borer: Larvae bore into young shoots causing wilting and dieback. Control: Apply cartap hydrochloride @ 0.1% or spinosad @ 0.05% spray at first sighting of shot-hole damage.
- Aphids: Clusters of small insects on underside of leaves causing curling and honeydew secretion. Control: Spray imidacloprid 17.8% SL @ 0.3 ml/L or release ladybird beetles as biological control.
🔬 રોગ નિયંત્રણ અને ઉપચાર
- Downy Mildew: Yellow patches on upper leaf surface with white fluffy growth underneath. Causal agent: Plasmopara halstedii. Control: Seed treatment with metalaxyl @ 3 g/kg seed; foliar spray of mancozeb @ 0.25% at first symptoms.
- Powdery Mildew: સફેદ powdery coating on leaves and stems reducing photosynthesis. Causal agent: Erysiphe cichoracearum. Control: Apply wettable sulfur @ 2–3 kg/acre in 500 L water or propiconazole @ 0.1% spray.
- Rust: Orange-brown pustules on lower leaf surface leading to premature leaf drop. Causal vector: Puccinia helianthi. Control: Remove and destroy infected plant debris; apply hexaconazole @ 0.1% as preventive spray.
✂️ કાપણી અને ગુણવત્તા માર્ગદર્શિકા
Harvesting at peak maturity ensures maximum commercial grade and long keeping quality.
⏱️ કાપણીનો સમય અને આયોજન
Single harvest at full physiological maturity, generally 90–105 days after sowing. Cut flower heads when the back turns pale brown/yellow and seeds harden.
