Pepper crop guide: 3.1.1 Haifa NutriNet™ web software for Nutrigation™ programs

| English

Haifa fertilization recommendations are available for everyone - enter into NutriNet™, a unique expert software program, that will assist you working out the recommended fertilizer rates at different growth stages according to the expected yield under your growing conditions.

The following is an example of recommendations, determined by NutriNet, with the assumption to split the scheduled fertilization into:
a) Base-dressing (pre-plant) fertilizers, followed by:
b) Nutrigation (fertigation) at different growth stages, on sandy-loam soil, when the expected yield is 65 ton/ha:

a) Base-dressing (kg/ha):

b) Nutrigation
Total amount of fertigation-applied fertilizers (kg/ha)

Example: Growing practice of peppers in Israel
Duration of the growth season:

In the southern part of the country (dry and hot climate) growth season of pepper in net houses starts on August and ends by the end of April. The season is rather long because of the scarcity of precipitates (ca 70 mm per year).
The summer growth term starts on April and lasts till the end of December.
In greenhouses and plastic tunnels the growth season is between August and April.
In open field the season starts on April and ends on June.

Table 13: NK ratio

Standard pepper plant density in Israel is 30,000 – 35,000 plants/ ha.
Average yield of open-field grown pepper in Israel is 55 – 70 T/ha.
Average yield of net house grown pepper in Israel is 90 – 110 T/ha.

	Kg / ha /Ton pepper yield
N	20-30
P₂O₅*	27.5
K₂O*	48-60
