MANAGEMENT OF FIELD OPERATIONS
1. FIELD PREPARATION
Prepare the land to a fine tilth.
2. SEED TREATMENT WITH FUNGICIDES
Treat the seeds with any one of the following fungicides. Carbendazim or Thiram at 2 g/kg seed.
3. FERTILIZER RECOMMENDATION
Apply basally 12.5 t/ha FYM/Compost, 12.5 kg/ha nitrogen, 25 kg/ha phosphorus , 12.5 kg/ha potassium if soil is deficient in NPK status.
4. SEED TREATMENT WITH BIOFERTILIZER
Treat the seeds with 3 packets (600 g/ha) of Rhizobial culture and 3 packets (600 g/ha) of Phosphobacteria developed at TNAU using rice kanji as binder. If the seed treatment is not carried out apply 10packets of Rhizobium (2000 g/ha) and 10 packets(2000 g) of Phosphobacteria with 25 kg of FYM and 25 kg of soil before sowing. Dry the biofertilizer treated seeds in shade for 15 minutes before sowing.
SEED RATE
For a pure crop 20 kg/ha is needed.
5. SOWING
Dibble the seeds with a spacing of 30 x 10 cm.
6. WEED MANAGEMENT
Give one weeding and hoeing on 25-30 days after sowing
7. HARVESTING
Harvest the matured whole plant, thresh the pods and extract seeds.
