Welcome to Brinjal Crop management and Diagnostic solutions
Brinjal Cultivation : : Seed rate & Nursery management
Seed
rate :
For raising one hectare crop,
200-250 grams of seeds are required for open pollinated varieties
whereas for hybrids 100-120g seeds are sufficient. The nursery is
sown on raised beds of 1.25 m width and 20 cm height. Fumigation
with 1.5% solution of formalin is found effective for controlling
the mortality at seedling stage. Seed treatment with fungicide like
or Captan at 3g/kg of seed before sowing protects the seedlings from
soil borne diseases. Seed priming with gibberellins improves the
seed vigour, germination and uniformity of the nursery. Seed
treatment with IAA (30 ppm) and subsequent application of Phorate
and Chlorantranilitreole (corazen @0.3ml/liter) showed
beneficial effect on yield and control of shoot and fruit borer. In
order to get better crop establishment and to have uniform, healthy
seedlings which are free from pests and diseases at the time of
planting, it is advised to use portray raised seedlings.
Nursery management :
Well-drained area
near the water source is an ideal place for raising nursery. Raised
beds are preferred over flat beds for raising the nursery because of
better aeration and drainage. Root development and uprooting of
seedling is better in raised beds. 200-250g of seeds are required
per hectare for open pollinated varieties where as 100-120g of seed
is required for F1 hybrids. In soil with good tilth raised nursery
beds of 8m wide, 15cm high and of convenient length are prepared.
Ten kg well decomposed FYM, 100g of 15:15:15
OR 19:19:19: complex fertilizer along with 2.5g carbofuran per m2 is
incorporated. The beds are drenched with Captan (2g/litre.) or copper
oxychloride (4g/litre.). Seeds are sown thinly in rows 10cm apart, 0.5cm deep.
The beds are covered thinly with compost
before mulching with dry straw or grass. Remove the grass covered
after the seeds have germinated. On germination (6-8 days) the beds
are drenched with Captan or copper Oxychloride. The seedlings will
be ready for transplanting in about 5-6 weeks (35-40 days). Two to
three sprays of monocrotophos (1ml/ litre) plus Zineb or Maneb(2g/
litre) in the nursery is essential, one of the sprays being given a
day or two prior to transplanting.
During the last week in the nursery, the
seedlings may be hardened by slightly withholding irrigation water.
After the appearance of first true leaf, seedlings are thinned out.
The seedlings with 3-4 true leaves are
transplanted within 4-6 weeks of sowing.
During Kharif the seedlings are sprayed with
cypermethrin(Cymbush) (0.5ml/l.) and Chlorothalonil (Kavach) (2g/l.) on 20th day
and one day prior to transplanting to control mylocerous weevil and
cercospora leaf spot respectively. Immediately after germination
drench the nursery with 0.2% captan to avoid damping off diseases.
. To get better and uniform crop stand,
seedlings of F1 brinjal can be raised by the use of plastic seedling
trays and decomposed sterilized cocpeat. For protecting the
seedlings from insect pest and diseases and to moderate the
environment during nursery stage, seedlings can be raised inside a
protected structure made of wooden poles or stone pillars and 40
mesh nylon net under 50% shade or in poly house
