Vegetative–generative balance: the key to a profitable season
Greenhouse bell pepper crops for 8–10 months; the plant must stay balanced between vine growth and fruiting. A “vegetative” plant sets few, late fruit; a “generative” plant tires and produces small, short fruit. Nutrition, temperature and fruit-load tuning are your three levers.
Staged nitrogen program
- Until first flowering: full nitrogen to build the plant skeleton;
- First fruit wave: cut nitrogen 20–30% and raise potassium;
- Later pickings: keep K:N high to preserve firmness and colour.
Calcium: fruit insurance
Blossom End Rot is a calcium transport failure in the fruit — not always a soil shortage. Uniform root moisture, low solution salinity and absorbable calcium nitrate are the three preventions.
Fruit-load tuning
For blocky peppers, keeping 3–4 fruit per plant on the first flush (by plant strength and season) is standard; remove extra or misshapen fruit early so energy goes into marketable fruit. Reduce load temporarily during heat waves.
Monitor EC & pH
Keep feed solution EC within 2–3 depending on substrate/soil; hold pH between 5.5 and 6.5 so micronutrients (especially iron and boron) stay available. Sample drainage solution every two weeks.
Summary
With the right variety (Yelora F1 for yellow, Flimora F1 for green-to-red), staged nutrition and load tuning, 4–6 kg per plant across a long season is realistic.
