Abstract
The present investigation entitled "Studies on effect of foliar
application of plant growth regulators on growth, yield and quality of chilli
(Capsicum annum L.)" Cv. PBNC-1 was conducted during 2016- 2017, at
Instructional-cum-Research Farm, ·nepatiment of Horticulture, College of
Agriculture, Latur, VNMKV, Parbhani with object to study the effect of plant
growth regulators on growth, yield and quality of chilli var.PBNC-1. The
experiment consists of eight treatments consisting viz. NAA@ 25 and 50" ppm,
GA3@ 10 and 20 ppm, 2,4-D@ 5 and 10 ppm, Ethephon@ 50 and 100 ppm,
Paclobutrazol@ 10 and 20 ppm, CIPA@ 20 and 40 ppm, Alar@ 50 and 100
ppm and control ( water spray). The experiment was laid out in Randomized
Block Design with three replications.
The observations on srowth attribute~ viz. height of.plant, number of
branches per plant, spread of plant and stem girth, : Effect on flowering viz.
days required to first flowering, days required to 50% flowering and days to
first harvesting.: effect on fruits viz. length of fruit, diameter df fruit, pericarp
thickness, fruit stalk length, weight of seed per fruit and seed recovery
percentage.: effect on quality viz. fruit colour, fruit shape, fruit texture and seed
colour.: effect on yield attributes viz. number of fruits per plant, weight of fruit
per plant, yield per plot and yield per hectare.: effect on insect pest incidence
were recorded.
Significantly maximum height of plant (83 .13cm), number of branches
. 2
per plant (19.07), spread of plant (793.67cm ) and stem girth (4.38cm) were
recorded by the foliar application ofNAA@ 25 and 50 ppm, respectively.
The minimum days to first flowering, days to 50% flowering and days
0
to first harvesting recorded by foliar application of Ethephon@ 50 and 100
ppm. The maximum length of fruit, diameter of fruit, pericarp thickness, fruit
stalk length, weight of seed per fruit and seed recovery percentage were
obtained by application ofNAA@ 25 and 50 ppm. The minimum incidence of
insect and pest recorded by application of2, 4-D@ 5 and 10 ppm.
Present investigation indicated that, the highest yield ( q/ha) and B: C
ratio with good quality of chilli fruit should be obtained by foliar application of NAA@ 25 and 10 ppm.
