The present investigation entitled “Studies on the effect of planting methods, ABSTRACT
The present investigation entitled “Studies on the effect of planting methods, mulching
and NAA application on bell pepper (Capsicum annuum L.) production” was carried out at the
Experimental Farm of the Department of Vegetable Science, Dr Y S Parmar University of
Horticulture and Forestry, Nauni, Solan (HP) during Kharif seasons of year 2017-18 and 2018-19
with the objective to evaluate the effect of planting methods, mulching and NAA application on fruit
yield, quality and incidence of disease(s) in Bell Pepper. The experiment was laid out in a randomized
block design (factorial) with three replications comprising twelve treatments. The seedlings of cv.
“Solan Bharpur” were transplanted on April, 2017 and 2018 at a spacing of 60 × 45 cm in 1.20 × 9.45
m size plots. The experiment was comprised of two planting methods viz., P1 (raised bed planting
method) and P2 (flat bed planting method), three levels of mulch materials viz., M1 (black polythene
mulch), M2 (double colored polythene-silver/black mulch) and M3 (no mulch) and two NAA levels
viz., N1 (application of NAA @ 15ppm at 30 and 45 days after transplanting) and N2 (no NAA
application). Thus, there were 12 treatment combinations in all replicated thrice. The observations
were recorded on plant height (cm), number of branches per plant, days to 50 per cent flowering, days
to first picking, harvest duration (days), fruit length (cm), fruit breadth (cm), pericarp thickness (mm),
fruit weight (g), number of fruits per plant, number of pickings, leaf area index, yield [per plant (kg)/
plot (kg)/ ha (q)], severity of leaf blight (%), incidence of collar rot and fruit rot (%), TSS (OBrix),
ascorbic acid content, capsaicin content (mg/100 g of fruit weight), shelf life (days), weed count,
weed control efficiency (%), weed intensity (%), fresh and dry weight of weeds (g per m2), soil
moisture content (%), soil temperature (OC) and economics of different treatment combinations.
Results showed that raised bed planting method (P1), Silver/black polythene mulch (M2) and NAA
application @ 15 ppm at 30 and 45 days after transplanting (N2) proved best for yield and yield
contributing traits. Two way interactions like P1M1, P1M2, M1N1, M2N1, P1N1 and P1N2were rated as
the best treatment combinations in terms of all the growth, yield and quality parameters. Studies also
revealed that P1M2N1 (raised bed, silver mulch with NAA application @ 15 ppm at 30 and 45 days
after transplanting) yielded maximum (384.69 q/ha) as well as recorded maximum values of gross
return (Rs.577,035.00/-), net return Rs.3,52,416.93/- and comparatively less B:C ratio (1:57).
