Safe Fertilisers – Crop Info
Cucumis sativus
Origin: Asia and Africa
Edible Portion: Fruit

Climatic Requirements: Frost tender crop that can only be grown outdoors after the last frost has
Preferred Soil Type: Well structured, high organic matter, free draining loams and silt loams.
Seed Required: 1.1-1.7kg/ha.
Optimum Soil Temperature Range for Germination: 15.5-35.0°C.
Emergence Time: 3-13 days, optimum 7 days.
Plant Spacing: In-row 30.0-60.0cm, between rows 150.0-180.0cm.
Plants per Hectare: 9,200-22,000.
Method of Propagation: Usually sown in situ either by hand or with precision seeding equipment.
2-3 seeds are sown at each site. For early production plants can be raised under glass and transplanted
into the field when frosts have passed.
Sowing Dates: Early crop – September to early October. Main crops – Late October to late
November. Glasshouse propagation – August.
Planting Out Dates: October to November.
Other Sowing and Planting Information: Do not sow or plant in land that has been treated with the
herbicides atrazine, metribuzin or diuron the previous season. A fine seed bed assists the germination
of the seed.

Optimum Soil Test Levels:
N = 100-150, P = 80-100, K = 30-40, Mg = 35-50, Ca = 12-18, Na = 1-
Base Dressing (kg/ha): N = 40.0, P = 50.0, K = 75.0. The base fertiliser should be applied and well
worked into the soil prior to seeding or planting.
Side Dressing (kg/ha): N = 25.0. The nitrogen side dressing is applied after the plants begin to run
and when the first flowers have appeared. With early direct seeded outdoor crops some extra nitrogen
side dressing may be required immediately after germination to give an initial boost. It is essential
not to allow the nitrogen fertiliser to contact the leaves as severe burning will occur.
Optimum pH Range: 6.5-6.7. Satisfactory crops can be produced over a pH range of 5.5-6.8.
Lime Requirement: For pH correction only.

Important Pests and Their Control:
Aphids – chlorpyrifos, deltamethrin, permethrin/pirimiphos-methyl, phorate, primicarb
Cutworm – chlorpyrifos, esfenvalerate
Whitefly – buprofezin, permethrin/primiphos-methyl
Important Diseases and Their Control:
Angular leaf spot – cupric hydroxide
Anthracnose – captan, mancozeb
Downy mildew – captan, chlorothalonil, cupric hydroxide, mancozeb, metalaxyl
Powdery mildew – benomyl, chlorothalonil, chlorothalonil, chlorothalonil/thiophanate-methyl,
dinocap/myclobutanil, penconazole, pyrazophos, sulphur, triadimefon, tridemorph, triforine
