Climate and soil
Red gram (pigeon pea) is less suitable for the tropics. The most favourable temperature
range is 18-30ºC. The crop is grown at a wide range of elevation. Red gram can be
grown in almost all soil types that are not very poor in lime and are not subjected
to waterlogging. Optimum growth and yield are obtained in deep loam soils. Red gram
can be grown as mixed crop with groundnut, paddy or tapioca or as a pure crop.

Sowing can be done in two seasons. As a mixed crop, sow the seeds in June-July.
When sown with groundnut, spacing recommended between rows is 3 to 3.5m. Red gram
can also be sown in paddy fields after the harvest of mundakan crop (either broadcast
or dibbled). In the dibbled crop, a spacing of 35 cm between rows is recommended.
Thinning is to be done, if necessary.

Weeding and intercultivation once in three weeks will ensure a good crop.
Plant
protection
Pod borer is the main pest. For controlling this, spray the crop with 0.05% Quinalphos
suspension at the time of flowering. The blister beetle, Zonabris gregariously
feeds on the flowers. Against this, Malathion 10% DP may be applied at the flowering
stage.
