Special features of Lucerne CO 2
- More number of stems per crown with soft and dark green leaves
- High crude protein (23.5 %) and dry matter yield (21.94 t/ha/yr)
- Profuse flowering nature leads to enhanced seed yield
- Superior ratooning ability and early flowering render 14 harvests per year
- Highly palatable, preferred by milch cattle, goat, sheep and horses

*Maximum permitted at and after flowering.
**Objectionable weed shall be: Dodder (Cuscuta spp.)
Season |
: |
- Seed production is done once in a year during summer months
- Green fodder should be harvested during first week of March and allowed for seed production in such a way that the peak period of flowering should coincide with summer.
|
Pre-sowing Seed treatment |
: |
- Treat the seeds with 600 g of Rhizobium and 600 g of Phosphobacteria before sowing.
Seed rate : 20 kg/ha
Spacing : 25 cm x 10 cm |
Foliar application |
: |
- Spray Borax @150 ppm to increase the seed quality.
- Spray ZnSO4 + Borax at 0.3% to improve pod and seed weight and also to increase the germination potential and vigour of seeds
|
Harvesting |
: |
Hand pick the pods at maturity stage |
