Abstract
The field experiment was conducted to study the effect of planting geometry
and foliar spray of micronutrients on plant growth, seed yield and quality of bell
pepper (Capsicum annuum L.) at Agricultural Research Station, Bagalkot, University
of Agricultural Sciences, Dharwad during rabi 2010-2011. The experiment was laid
out in split plot design consisting of 15 treatment combinations with 3 spacings as one
factor and 5 foliar sprays of micronutrients as another factor, three sprays were given
at 30, 45 and 60 days after transplanting.
The spacing of 60x45 cm took least number of days to 50 per cent flowering
(44.33) and maturity (68.6) and borne more number of fruits per plant (7.50), higher
fruit yield per plant (337.05g) and seed yield per plant (7.63g). But spacing of 45x45
cm recorded significantly higher seed yield per ha (352.88 kg).Seed quality parameter
like germination (81.25%), seedling vigour index (93.97), seedling dry weight
(49.21mg) with lower electrical conductivity (0.37dSm-1) of seed leachate were also
observed with spacing of 60 x 45 cm.
Among the foliar spray of micronutrients borax (0.5 %) recorded significantly
less number of days (43.56) to 50 per cent flowering and to maturity (73.33) with
more number of fruits per plant (8.3g) and fruit yield per plant (377.8g). Significantly
higher number of seeds per fruit (221.20), seed yield per fruit (1.06g), seed yield per
plant (8.63g) and seed yield per ha (342.45kg). Quality parameters like higher
germination (83.82%), seedling vigour index (1000.4), seedling dry weight (51.10mg)
with lower electrical conductivity (0.36dSm-1) were recorded with borax (0.5%) foliar
spray.
In terms of economics spacing of 45x45 cm with borax (0.5%) foliar spray
gave higher net returns of Rs. 1,96,480 per ha with the cost of seed production of Rs.
88,870 per ha and a Cost Benefit Ratio of 1:3.21.
