ABSTRACT
The present investigation entitled “Effect of mulching and planting geometry on seed
production in bell pepper (Capsicum annuum L.)
’’
was carried out using cv. Solan Bharpur. The
experiment was laid out in Split-Split Plot Design in the field and in Completely Randomized Block
Design (Factorial) in Laboratory with three replications of each treatment combination in both the
experiments at Department of Seed Science and Technology, Dr YS Parmar University of
Horticulture and Forestry, Nauni, Solan (HP) during Kharif 2013. The treatment combinations
comprised of four different mulches (M) viz., no mulch (M1), black-plastic mulch (M2), silver-black
plastic mulch (M
3) and crop residue mulch (M4), three row layouts with constant population (L) viz.,
recommended single row 60×45 cm (L1), double row (75+45)×45 cm (L2), and double row
(90+30)×45 cm (L3
) and two plant layouts (P) viz., rectangle/square (P1), and triangle (P2). The
observations in field were recorded on plant height(cm) 30 days after transplanting (DAT), 60 days
after transplanting (DAT), 90 days after transplanting (DAT) and at final harvest, days to ripe fruit
harvest, ripe fruit weight (g), ripe fruit length (cm), ripe fruit width (cm), number of ripe fruit per
plant, ripe fruit yield per plant (g), ripe fruit yield per plot (Kg), ripe fruit yield per hectare (quintals),
number of seed per fruit, seed yield per plant (g),seed yield per plot (g), seed yield per hectare (Kg),
per cent seed recovery, ripe fruit rot incidence (%), 1000 seed weight (g) and benefit: cost ratio. While
the observations recorded in the laboratory were seed germination (%), seedling length (cm), seedling
dry weight (mg), seedling vigor index-L & M. Analysis of variance showed significant differences
among the treatment combinations for all the characters studied. The treatment combination silverblack mulch, double row (75+45)×45 cm and triangle method of planting (M3L2
P
2) was found
superior over all other treatments in terms of growth characters, fruit yield characters, seed yield
characters, seed quality characters and had maximunbenefit: cost ratio. Therefore, silver-black mulch
in combination with double row (75+45)x45 cm and triangle plant layout i.e. M3L2
P
2 can be
recommended for commercial seed production of bell pepper in Himachal Pradesh.
