Description An experiment was conducted to study the effect of seed coating polymer, fungicide
and insecticide on storability and field performance of cotton. The experiment consisted of
eleven treatments seed coating polymer @ 3.00, 4.00 and 5.00 g per kg of seed and in
combination with thiram @ 1.50 g per kg of seed, and imidacloprid @ 7.50 g per kg of seed.
The results of storage experiment indicated that seed coating with thiram @ 1.50 g per kg of
seed and imidacloprid @ 7.50 g per kg of seed recorded significantly higher germination
(77.40%), root length (16.56cm), shoot length (9.98cm) vigour index (2054), seedling dry
weight (34.50 mg/ seedling), electrical conductivity (0.980dSm-1), pH (6.600), insect
infestation (3.65%), seed mycoflora (5.65%) and test weight (5.420g) followed by seed
coating with polymer @ 5.00 g per kg of seed and thiram @ 1.50 g per kg of seed was
recorded higher germination (76.10%), root length (16.00cm), shoot length (9.77cm) vigour
index (1976), seedling dry weight (31.00mg/ seedling), electrical conductivity (1.050dSm-1),
pH (6.500), and seed mycoflora (6.88%) as compared to control at the end of nine months of
storage.
During field studies the seed coated with thiram @ 1.50 g per kg of seed and
imidacloprid @ 7.50 g per kg of seed recorded significantly higher plant stand(72.00 %),
plant height(57.00cm), number of monopodial (2.12) and number of sympodials
branches(14.00), lower population count of leafhopper (1.70), whiteflies(1.74), aphids(1.62)
and thrips (1.30) followed by seed coating with polymer @ 5.00 g per kg seed and
imidacloprid @ 7.50 g per kg of seed was recorded higher plant stand (67.10%), plant height
(55.00cm), number of monopodial (2.00) and number of sympodials branches (13.50), lower
population cont of leafhopper (1.78), whiteflies (1.77), aphids (1.67) and thrips (1.40) and
less disease intensity up to 45 days.
