In Himachal Pradesh, this crop is cultivated under rainfed conditions. A well drained sandy soil with a layer of loamy sub-soil is considered ideal for this crop. Under irrigated conditions, the crop can be raised in the sandy loam and loamy soil as well. Growing the crop repeatedly in the same soil year after year should be avoided to discourage the build-up of soil borne diseases. The land should be ploughed twice and left open to sunlight in May-June after the harvest of the previous crop.
