Ingredients:
- 10 to 20 cubic meters of well-rotted manure + 4 cubic meters of chicken litter
- 5 to 8 bags of fine superphosphate
- 1 bag of granular superphosphate
- 2 bags of ammonium sulfate (like Suez salt)
- 25 kg of fine potassium sulfate
Mix all these quantities and place them along the planting rows, then cover them before planting.
Important Note:
First, layout the field, and then apply 100 kg of agricultural sulfur on the rows.
Fertilization Program:
- First 15 Days: No fertilization is needed because the soil will still be soft.
- Fertilization with each irrigation, typically every 12 days.
- Day 28:
- Apply 50 kg of ammonium sulfate
- Apply 25 kg of potassium sulfate
- Apply 7 kg of phosphoric acid
- Day 40:
- Apply 100 kg of ammonium nitrate
- Apply 50 kg of fine potassium sulfate
- Apply 10 kg of phosphoric acid
- Day 52:
- Apply 100 kg of ammonium nitrate
- Apply 150 kg of calcium nitrate
- Apply 25 kg of magnesium nitrate
- Day 64:
- Apply 100 kg of ammonium nitrate
- Apply 25 kg of magnesium sulfate
- Apply 50 kg of potassium sulfate
- Apply 5 kg of phosphoric acid
- Day 76:
- Apply 50 kg of ammonium nitrate
- Apply 50 kg of potassium sulfate
- Apply 5 kg of phosphoric acid
- Day 88:
- Apply 25 kg of potassium nitrate
Spraying Program
Spray micronutrients every 10 days, starting from Day 25:
- (500 grams of iron + 500 grams of zinc + 500 grams of manganese)
- (1 liter of calcium boron every 10 days from Day 40 until the end)
Cost Breakdown:
- 5 bags of ammonium sulfate: Total cost 750 EGP
- 1 bag of ammonium nitrate: Total cost 1440 EGP
- 31 kg of phosphoric acid: Total cost 300 EGP
- 9 bags of potassium sulfate: Total cost 2025 EGP
- 3 bags of calcium nitrate: Total cost 750 EGP
- 1 bag of magnesium sulfate: Total cost 75 EGP
- 1 bag of magnesium nitrate: Total cost 150 EGP
- 1 bag of potassium nitrate: Total cost 500 EGP
Total fertilization cost per feddan: 5980 EGP
It’s crucial to manage powdery mildew and early blight in this crop cycle. Use a pesticide called (Dithane), which effectively controls both diseases at a rate of 100 ml per 200 liters of water. You can start spraying 20 days in, which is excellent for prevention.
Note: Prices may vary; they are not fixed. There are cheaper and more expensive products available.
