AGRICULTURE NEWS - The calcium level should also be adequate; insufficient calcium can lead to blossom end rot.

This usually occurs where there is a good crop and the plants experience water stress. 

It can be extremely upsetting to expect a good income from a crop, only to suffer major damage within days.

Peppers that develop symptoms of calcium deficiency, such as browning of the stem end, are unmarketable. Ignoring or accepting water stress when the crop is in full production is very risky.

Nitrogen
The nitrogen level can be determined visually by the vigour of the plants, which includes leaf size and colour. Keep them a healthy, dark green.

If the leaves become a medium green, the fruit is likely to have a thinner wall. Customers will pay more for thicker walls.

Apart from this, supplying the plant with enough nitrogen will encourage it to set more fruit, as the amount of fruit the plant can sustain depends on total leaf area and health.
