Field Preparation

Land preparation

Prepare the land to fine tilth and apply 12.5 t FYM ha-1 / composted coir pith at the time of last ploughing and form raised beds so that the laterals are placed in the centre.

Varieties and Seed rate

LRG 41 pigeonpea were obtained from the Zonal Agricultural Research Station, Lam, Andhra Pradesh. The seed rate recommended is 2.5 kg ha-1.

Seed treatment

Treat the seeds with Carbendazim or Thiram @ 2 g/kg of seed 24 hours before sowing (or) with talc formulation of Trichoderma viride @ 4g/kg of seed (or) Pseudomonas fluorescens @ 10 g/kg seed. Bio control agents are compatible with biofertilizers.
First treat the seeds with biocontrol agents and then with rhizobium.
Fungicides and biocontrol agents are incompatible.
Fungicide (or) bio control agents treated seeds should be again treated with bacterial culture after 24 hours.
Treat the seeds required for sowing 1 ha with Rhizobial culture CRR 6 / CPR 9, phosphobacteria (Bacillus megaterium) and PGPR (Pseudomonas sp.) developed at TNAU, with three packets each (600g).
For red lateritic soil, Rhizobial culture VPR 1 is effective.
Using rice kanji as binder, Rhizobium should be given as seed treatment only.
For PSB and PGPR, if the seed treatment is not carried out, apply 10 packets (2 kg) of Phosphobacteria (Bacillus megaterium) and 10 packets (2 kg) of PGPR (Pseudomonas sp.) with 25 kg of FYM and 25 kg of soil before sowing.

Crop geometry

Dibble the seeds adopting the following spacing

Variety	Spacing (cm)
LRG 41	150 x 60

Season

Long duration and Medium duration varieties: Optimum time of sowing is between second fortnight of July and August months.

Note: Sowing season should be planned in such a way that flowering and pod maturity stages does not coincide with rainfall.
