Climate & Soil
Black gram may be grown as pure crop in rice fallows after the harvest of the first
or second crop of paddy. It can also be grown as pure or mixed crop during kharif
season.
Varieties
- T-9 (moderately tolerant to drought condition)
- Co-2 (photo insensitive;
but pest and disease susceptible)
- TAU-2 (suited for partially shaded condition
in coconut garden during rabi season in southern region)
- TMV-1, KM-2 (suited
for Onattukara tract during late kharif )
- Syama (suited for the summer rice
fallow of Onattukara)
- Sumanjana (high yielding and early maturing variety, suitable
for summer rice fallows of Thiruvananthapuram district)
- S-1 (Suitable for pappad making)
Seed rate and sowing
Pure crop - 20kg/ha
Mixed crop - 6kg/ha
Plough the land 2-3 times thoroughly and remove weeds and stubbles. Spacing of 25cmx15cm
will give better yield. For seed treatment in black gram, two Rhizobium cultures
viz. KAU-BG-2 and BG-12 are recommended.
