🌾 જમીનની તૈયારી અને ખેડ
જમીનની યોગ્ય તૈયારીથી એકસરખો ઉગાવો અને મૂળનો ઊંડો વિકાસ સુનિશ્ચિત થાય છે.
🌱 યોગ્ય જમીનનો પ્રકાર અને pH
Well-drained loamy to clay-loam soils with pH 6.0–7.5. The variety performs optimally in deep, fertile soils with good organic matter content and moderate moisture retention capacity.
✨ મુખ્ય કૃષિ ફાયદા
Loamy soil structure promotes rapid germination, strong root anchorage for tall non-lodging plants, and efficient nutrient uptake for excellent tip filling.
- 1
Deep summer ploughing to 25–30 cm followed by 2–3 cross-harrowings for fine tilth and weed seed burial.
- 2
Field leveling using laser or pipe level for uniform water distribution and consistent germination across the field.
- 3
Incorporation of 10–12 tonnes per hectare of well-decomposed FYM or compost during the final harrowing to build soil organic carbon.
- 4
Soil health conditioning: apply gypsum at 250 Kg/Ha in alkaline/sodic soils and sulfur at 40 Kg/Ha in deficient soils to maintain near-neutral pH.
🌱 વાવણીનો સમય અને પદ્ધતિ
Precise seed rate and spacing maximize light interception and canopy development.
| માપદંડ / પેરામીટર | ભલામણ / સૂચના | કૃષિ મહત્વ |
|---|---|---|
| વાવણી સમયમર્યાદા | ઓક્ટોબરથી નવેમ્બર for Rabi; June to early July for Kharif monsoon sowing | Sowing within this window ensures optimal temperature (25–32°C) and moisture conditions for uniform germination and avoids pre-monsoon drought stress. |
| બિયારણનો દર (એકર દીઠ) | 40–42 Kg per Hectare (16–17 Kg per Acre) | Maintains optimal plant population of approximately 55,000–60,000 plants/Ha for balanced canopy development and non-lodging stand. |
| હાર અને છોડ વચ્ચેનું અંતર | 60 cm Row-to-Row x 20 cm Plant-to-Plant (or 75 x 20 cm for Rabi) | Ensures adequate canopy spread, inter-row aeration, light penetration, and reduces disease humidity buildup while supporting tall plant architecture. |
| વાવણીની ઊંડાઈ | 5–7 cm under normal conditions; 7–8 cm in lighter sandy soils | Promotes uniform germination, proper seed-soil contact, and deeper root establishment for lodging resistance. |
💧 પિયત અને પાણી વ્યવસ્થાપન
Adequate moisture regulation supports strong vegetative and reproductive growth.
☀️ પાણીની જરૂરિયાત અને પિયત પ્રોફાઇલ
સફેદ મકાઈ Shaurya 1818 is highly responsive to irrigated conditions. Maintain soil moisture at 60–70% of field capacity throughout the growing cycle. Under drip irrigation, apply 3–4 cm water per irrigation every 3–4 days during peak vegetative and grain-filling stages. The crop is moderately drought-sensitive during flowering and early grain-filling; even brief moisture stress at silking can reduce tip fill quality.
🌦️ Soil ભેજ વ્યવસ્થાપન
In rainfed or low-rainfall zones, sow immediately after a soaking rain to ensure adequate germination moisture. Use mulching (straw or polyethylene) to conserve soil moisture. Avoid waterlogging at any stage—install quick-drainage channels as white maize is sensitive to standing water beyond 24 hours.
- ✓
First irrigation at 20–25 DAS (tillering stage) to establish robust root system and promote uniform seedling growth.
- ✓
Vegetative phase: irrigate every 10–12 days during active leaf and stem growth to sustain vigorous foliage development.
- ✓
Critical stage — silking to dough stage (45–70 DAS): maintain consistent moisture; any deficit here directly compromises tip filling and kernel solidity. Apply irrigation at 7–8 day intervals during this window.
- ✓
Withhold irrigation 10–12 days before expected harvest to allow natural drying of grain moisture and improve keeping quality.
🧪 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) | 120–150 Kg per Hectare | 50% basal at sowing (along with P and K); remaining 50% split as top-dressing at 30 DAS and 50 DAS. Under high-response irrigated conditions, consider a third split at boot stage for sustained green foliage. |
| ફોસ્ફરસ (P₂O₅) | 60 Kg per Hectare | 100% basal application incorporated at final seedbed preparation. Use DAP (18-46-0) or SSP to deliver both P and supplementary S/Zn. |
| પોટાશ (K₂O) | 50–60 Kg per Hectare | Apply 50% basally with P and remaining 50% at 40–45 DAS to support stalk strength, lodging resistance, and kernel firmness for excellent tip filling. |
🌿 નિંદામણ નિયંત્રણ અને આંતરખેડ
Timely weed control ensures optimal nutrient and moisture availability for crop seedlings.
-
1
પ્રથમ નિંદામણ અને ગોડ: Carry out shallow hoeing and weeding at 15–20 DAS before weed seeds germinate and compete for nutrients. Use a rotary weeder or hand hoe carefully to avoid root damage. Early weed control during this window is critical for establishing vigorous crop stand.
-
2
બીજી વાવણી અને પાળા ચઢાવવા: Perform second weeding and earthing-up at 35–40 DAS. Mounding soil around the base strengthens brace roots, improves lodging resistance for tall plants, and enhances root zone aeration during heavy irrigation or monsoon rains.
-
3
વિશેષ આંતરખેડ કામગીરી: Apply organic or black plastic mulch between rows at 20 DAS to conserve moisture, suppress weeds, and moderate soil temperature. In high-population sowing, remove excess suckers (secondary tillers) at 30–35 DAS to direct assimilates toward primary ear development and improve tip filling uniformity.
🛡️ જીવાત અને રોગ નિયંત્રણ
Proactive crop monitoring and integrated management ensure healthy crop development.
🐛 જીવાત નિયંત્રણ અને સંરક્ષણ
- Shoot Fly (Atherigona soccata): Sucks sap from young seedlings causing 'dead heart' symptom and central leaf death. Control: Spray Phosalone 35 EC at 1.5 ml/L or Chlorpyriphos 20 EC at 2 ml/L at 10 and 15 DAS as seedling protection. Apply carbosulfan granules at the base at 10 DAS as preventive measure.
- Pink Stem Borer (Sesamia inferens): Larvae bore into stem causing wilting, drying of upper leaves, and tunneling visible frass. Control: Install pheromone traps at 10/acre for monitoring. Spray Cartap hydrochloride 4 GP at 1 kg/acre in leaf axils at 35 and 50 DAS, or use Chlorantraniliprole 18.5 SC at 0.3 ml/L at first sign of infestation.
- Corn Stalk Borer / Stem Borer (Chilo partellus): Adults lay eggs near leaf margins; larvae enter stems causing irregular holes and entry points for secondary rot. Control: Practice deep ploughing to expose overwintering larvae. Spray Spinosad 45 SC at 0.3 ml/L or Emamecin benzoate 5 SG at 0.4 g/L at peak flowering when moth activity is highest.
🔬 રોગ નિયંત્રણ અને ઉપચાર
- Northern Corn Leaf Blight (Exserohilum turcicum): Characteristic cigar-shaped grey-green lesions on upper leaves reducing photosynthetic area. Preventive: Remove crop residue post-harvest to reduce inoculum. Spray Mancozeb 75 WP at 2.5 g/L or Propineb at 2 g/L at early symptom appearance and repeat after 10 days if needed.
- Downy Mildew (Peronosclerospora sorghi): Downy white fungal growth on leaf underside, yellowing and stunting of infected plants. Control: Use seed treatment with Metalaxyl 35 WS at 4 g/Kg seed before sowing. Foliar spray of Mancozeb 75 WP at 2 g/L at first sign of disease spread in humid conditions.
- Stem Rust (Puccinia sorghi): Raised reddish-brown pustules on lower leaf surfaces causing premature leaf senescence. Management: Ensure adequate potassium nutrition to strengthen cell walls. Apply Sulphur dust (80%) at 15 Kg/acre or spray Triforine at 0.1% if disease pressure is high during cool, humid periods.
✂️ કાપણી અને ગુણવત્તા માર્ગદર્શિકા
Harvesting at peak maturity ensures maximum commercial grade and long keeping quality.
⏱️ કાપણીનો સમય અને આયોજન
Harvest when 80–85% of silks turn brown and kernels reach physiological maturity at full dent stage. harvest is typically at 95–100 DAS in Kharif and 110–115 DAS in Rabi. Harvest the entire crop at once as it is a single-harvest hybrid.
