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 one packet (200 g/ha) of Rhizobial culture and one packet (200 g/ha) of Phosphobacteria developed at TNAU using rice kanji as binder. If the seed treatment is not carried out apply 10 packets 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.
