Abstract
The laboratory experiment was carried out in the Department of Seed Science and
Technology, UAS, Raichur, to know the effect of seed polymer coating in groundnut. The
experiment consists of 6 treatments, among the treatments Polymer @ 4 ml per kg of seed
recorded significantly higher germination (77.00 %), speed of germination (22.13), shoot
length (15.99 cm), root length (6.14 cm), seedling dry weight (1.25 g) and seedling vigour
index (1725) compared control (74.00 %, 17.57, 13.54 cm, 4.02 cm, 0.89 g mg and 1326,
respectively).
The field experiment was conducted at MARS, College of Agriculture, UAS,
Raichur, to know the influence of seed polymerization with micronutrients and foliar
spray on growth, seed yield and quality of groundnut. The experiment consists of 23
treatments with various micronutrients either alone or in combination. Among the
treatments, seed polymerization (6 ml/kg) with the combination of micronutrients (ZnSO4
+ FeSO4 + Boron + Ammonium molybdate + CaSO4 each at 2 g per kg of seed) and foliar
sprays (except ZnSO4 and FeSO4 in EDTA form) at an interval of 10 days during
flowering stage (50 and 60 DAS) recorded significantly higher leaf area index (1.88, 4.02
and 1.50), chlorophyll content (43.16, 47.26 and 38.28 SPAD values), plant height
(12.33, 26.67 and 34.00 cm) at vegetative, flowering and pod formation stage, effective
root nodules (25/plant), pods (34.50/plant), seed yield per plant (20.80 g), seed yield per
hectare (8.89 q/ha) compared to control (1.34, 2.77 and 1.00, 36.36, 38.00 and 30.65
SPAD values, 8.67, 18.73 and 23.33 cm, 25, 2, 18.30 g/plant and 7.76 q/ha, respectively).
The resultant seeds of the same treatment also recorded significantly higher germination
(81.40 %) and seedling vigour index (1676) compared to control (74.00 % and 1258,
respectively).
