Soil Type and Site Selection
Kale grows best on a medium loam soil with a pH of around 6.5. It needs a well drained soil which is not compacted. If you have to grow kale on heavy soil remember strip grazing may be difficult during very wet periods.
Seed Bed
A firm, fine and level seedbed is required and this needs to be achieved with minimum moisture loss, especially on dry soils.
Sowing
Sow mid April – mid July. Broadcast at 2kg per acre or drill at 1-2kg per acre (2.5-5kg per ha).
The target is 70 plants per sq m. Good establishment and timely sowing usually give the best results.
Fertilizer
Kale is a fast growing crop which will thrive when provided with plenty of organic material like slurry or FYM. Apply P & K fertilizer to seedbed. The N may be split between the seedbed and a top dressing once the crop reaches 15-16cm.
