BRINJAL
|
| Land Requirements | No Specific requirements. Land should be free from volunteer plants. |
| Isolation Requirements |
Brinjal is partially self- and corss-pollinated , but self-pollination is more common. The extent of natural corssing depends upon insect activity and has been recorded from 0to 48 per cent. For pure seed production, seed fields must be isolated from other variety brinjal fields, and fields ofsame vareity not conforming to varietal purity requirements of seed certification at least by two hundred metres for foundation seed production, and one hundred metres forcertified seed production.
|
| Time of Sowing | Plains -
February to March, June to July, October to November;r Hills - March to April |
| Preparation of Land | For transplanting prepare the field to a fine tilth by ploughing and 3to 4 harrowings followed by leveling. |
| Source of Seed | Obtain breeder's/foundation seeds from source approved by a seed certification agency. |
| Seed Rate | 375 to 500 gms per hectare. |
| Sowing of Seeds in Nursery | Seeds may be sown on raised nursery beds. (15 to 20 cms high from the ground) inrows 2to 3cm apart. 25 nursery beds of size 2 to 2.5 meters long and 1 to 1.25 metres wide will raise enough seedlings to transplant one ha. |
| Fertilisation | Apply 20 to 25 tonnes of well-rotted farmyard manure at the time of land preparation; and 300 kg of Superphosphate, 125 kg potassium sulphate and 250 kg of amonium sulphate or C.A.N. before transplating .. Top-dress 250 kg ammonium sulphate or C.A.N. in two doses. the first fifteen days after transplanting, and the second at flowering time spread around the plants. Irrigate immediately after top-dressing. |
| Transplanting | Transplant the seedlings, when 12 to 15 cms in height, preferably at evening time. Irrigate immediately afterwards. |
| Spacing | (a) Non-spreading types: 60 x60 cm between rows
and plants. (b) Spreading type : 75 to 90 x 60 to 70 cm.. |
| Irrigation | Irrigate at two weeks interval during the summer |
| Interculture | Keep the fields free from weeds, and the soil well aerated by frequent hoeings. |
| Insect and Disease Control | Adopt recommended IPM methods |
| Roguing | Remove the offtypes. |
| Harvesting and Extration of Seeds |
Harvesting is done when fruits are fully ripe. the fruits are picked and collected. The outer covering is peeled off and the flesh with the seeds is cut into thin slices. These are then softened by soaking till the seeds are separated from the pulp. If the material is allowed in this condition tostand overnight, the separation of seeds from the pulp becomes easier. After separation, the seeds are dipped into water. those which float should be rejected. the seeds should then be dried in partial shade to a moisture content ofeight percent below, before storing. |
| Seed Yield | The average seed yield is about 100 to 200 kg per hectare. |
