Effect of different spacing and planting ratio on seed yield and quality parameters of chilli (Capsicum annuum L.) hybrid GAVCH 1

Abstract

An investigation was carried out to find the effect of spacing
and planting ratio on seed yield and quality parameters in
chilli at Main Vegetable Research Station, Anand and
Department of Seed Science and Technology, BACA, AAU,
Anand during Kharif-Rabi season of the year 2019-20. Plant
spacing 90 × 60 cm (S2) recorded significantly highest seed
yield per plant (23.98 g), number of fruits per plant (103.13),
germination per cent (95.11 %), seedling root length (4.71
cm), seedling shoot length (4.54 cm), seedling length (9.24
cm), seedling fresh weight (381.3 mg), seedling dry weight
(20.53 mg), seedling vigour index I (879.90) and seedling
vigour index II (1954.4). Irrespective of plant spacing, among
the three planting ratios, planting ratio 2:1 (P2) recorded
significantly higher number of fruits per plant (115.58), weight
of fruit (1.018 g), fruit length (9.32 cm) and fruit girth (3.97
cm), number of seeds per fruit (42.16), 1000 seed weight
(5.76 g), seed surface area (8.74 sq. mm), seed yield per plant
(27.54 g), germination (94.67%), seedling root length (4.61
cm), seedling shoot length (4.45 cm) and seedling length
(9.06 cm), seedling fresh weight (384.1 mg), seedling dry
weight (20.81 mg), seedling vigour index I (858.92) and
seedling vigour index II (1971.80). However, significantly
higher fruit to seed ratio (4.77) was found in 3:1 planting
ratio (P3) in seed parent of chilli hybrid
