MANAGEMENT OF FIELD OPERATIONS
1. FIELD PREPARATION
Prepare the land to fine tilth and apply 12.5 t FYM/ha
2. SEED TREATMENT
|
Treat the seeds with Carbendezim (or) Thiram @ 2g/kg of seed 24hrs before sowing (or) with talc formulation of Trichoderma viride @ 4 g/kg seed (or) Pseudomonas fluorescens @ 10 g/kg seed. Biocontrol agents are compatible with biofertilizers. First treat the seeds with biocontrol agents and then with Rhizobium. Fungicides and biocontrol agents are incompatible. |
The above seed treatment will protect the seedlings from seed borne pathogens in the early stages.
SEED RATE
- CO 3 - 90 kg/ha.
- CO 4 - 75 kg/ha.
As a pure crop to have an optimum plant population 325000 / ha
3. 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 (2000g/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.
4. FERTILIZER APPLICATION
a) Apply fertilizers basally before sowing.
Rainfed : 12.5 kg N + 25 kg P2O5 + 12.5 kg K2O +10 kg S*/ha
Irrigated : 25 kg N + 50 kg P2O5 + 25 kg K2O + 20 kg S*/ha
*Note : Applied in the form of gypsum, if Single Super Phospate is not applied as a source of phosphorus
b) Soil application of 25 kg ZnSo4/ha under irrigated condition
5. SOWING
Dibble the seeds by adopting the spacing of 30 cm x 10 cm.
6. WEED MANAGEMENT
i) Pre emergence application of Pendimethalin 2 litres on 3rd day after sowing using Backpack/ Knapsack/Rocker sprayer fitted with flat fan nozzle using 500 l of water for spraying one ha. followed by one hand weeding on 25 - 30 days after sowing.
ii) If herbicide is not applied give two hand weedings on 15th and 30th day after sowing.
7. INTERCROPPING IN BENGALGRAM
Bengalgram in paired row planting with one or two rows of Coriander as intercrop would give the highest return. Wheat can also be intercropped in deep black cotton soil in Coimbatore, Erode, Salem, Namakkal and Dharmapuri districts.
