Large-Scale Butternut Farming Project

 Target: Commercial farming (1–10+ acres)

Crop: Butternut squash (Cucurbita moschata)
Purpose: For local market, exports, processing (soups, puree, baby food)

---

1. Why Butternut?

• High demand in local markets and supermarkets

• Long shelf life (up to 3–6 months)

• Export potential (Europe, Middle East)

• Low disease pressure if managed well

• Good income per acre

2. Suitable Agro-ecological Conditions

Factor	Requirement
Altitude	0 – 1,800 m (thrives in warm to semi-humid areas)
Rainfall	600 – 1,000 mm annually
Soil type	Well-drained loam or sandy loam with pH 6.0–6.8
Temperature	18°C – 30°C
Water	Supplement with irrigation in dry periods

Ideal locations in Kenya: Makueni, Kitui, Machakos, Nakuru, Kajiado, Trans Nzoia, Laikipia, parts of Meru, Bungoma, and Kirinyaga.

3. Land Preparation

A. Field Requirements per Acre

• Clear bush and old crops

• Plough deeply (30 cm)

• Harrow to fine tilth

• Prepare ridges or raised beds for drainage

B. Spacing

Layout	Spacing
Between rows	1.5–2 meters
Between plants	0.9–1 meter

=> Approx. 4,000–5,000 plants per acre

4. Varieties to Grow

Variety	Maturity	Yield	Notes
Waltham	90–100 days	High	Sweet, firm flesh
Atlas F1	85 days	Very high	Hybrid, uniform size
Pluto F1	90 days	High	Good shelf life
Bravo	95–100 days	Moderate	Affordable, local

5. Planting Guide

Seeds

• Use certified hybrid seeds

• 1 acre = approx. 1–1.5 kg of seed

Germination

• Soak seeds for 6–12 hrs before planting

• Germinates in 5–7 days

Planting Depth

• 2.5–3 cm deep

• Plant directly or transplant nursery-raised seedlings (less common)

---

6. Fertilizer and Manure Application

Before Planting

• Well-rotted farmyard manure (2–3 tons/acre)

• DAP or TSP: 50 kg/acre at planting

After Germination (Top Dressing)

• CAN/Urea: 50 kg/acre at 3–4 weeks

• NPK (17:17:17) at fruiting stage: 50 kg/acre

Optional: Fertigation or Foliar feeds every 10–14 days during fruiting for hybrids

---

7. Irrigation (If Not Rain-Fed)

System	Notes
Drip irrigation	Best for efficiency
Furrow	Suitable for flat lands
Overhead/sprinkler	Can cause fungal issues if overdone

Water frequency: Every 3–4 days during dry periods; reduce during fruit maturity to avoid cracking.

---

8. Pest and Disease Management

A. Common Pests

• Aphids

• Whiteflies

• Squash bugs

• Cutworms

Control: Neem, Pyrethrum, Actara, or organic pesticides

B. Common Diseases

Disease	Solution
Powdery mildew	Use fungicides like Score, Milraz
Downy mildew	Copper-based fungicides
Fusarium wilt	Practice rotation
Anthracnose	Avoid overhead irrigation

C. Cultural Controls

• Crop rotation (avoid planting after other cucurbits)

• Weed regularly

• Prune excess foliage to improve aeration

---

9. Harvesting

Parameter	Notes
Time to maturity	90–100 days after planting
Sign of maturity	Fruit changes to tan/golden, stem starts drying
Yield per acre	10–15 tons (open pollinated), 15–25 tons (hybrid)
Shelf life	3–6 months in cool, dry store

Use pruning shears to cut fruit with 2–3 cm of stem attached to avoid rot.

---

10. Post-Harvest Handling

• Cure fruits in shade for 7–10 days for hardening

• Store in cool, dry place with ventilation

• Grade based on size, shape, and ripeness

• Pack in crates or mesh bags for transport

12. Market Outlets

• Local supermarkets and groceries

• Open-air markets (Gikomba, Wakulima, etc.)

• Exporters (with grading and phytosanitary certification)

• Processors (soups, puree, baby food)

• Institutions (schools, hospitals)

---

13. Final Tips

• Scout every week for pests and diseases

• Use mulch to retain moisture

• Consider intercropping with beans or cowpeas early for soil improvement

• Invest in quality storage to extend marketing window

• Consider value addition (chopped, dried, frozen) for longer-term gains
