Abstract
A field experiment was conducted at College of Agriculture,
Vellayani to study the influence of growth regulator and vegetable
picking on seed yield, quality and vigour and also to standardise the
stage of physiological maturity and seed position in chilli.
Plant height was increased with regular vegetable harvests. Other
growth characters like number of branches per plant, leaf area index,
leaf area duration and date of 50 per cent flowering were not affected
by vegetable harvests. The bearing capacity of the plant is improved
by frequent picking of green fruits, but the mature fruit yield was not
affected. Highest number of green fruits per plant, total number of
fruits harvested per plant and highest fruit to seed ratio was recorded
in treatment h2 (first two seed harvest and rest for vegetable
harvests). Zero vegetable harvest recorded maximum weight of seeds
per fruit, 1000 seed weight, seed yield per ha and B:C ratio. Seed
quality is not influenced by number of harvests. To obtain maximum
returns, raising crop for seed purpose alone can assure good quantity
and quality seeds.
Growth regulator caused reduction m vine length but increased
the number of branches and length of fruits. NAA at 50 ppm
produced significant increase in LAI, weight of green fruits, weight
and number of seeds per fruit&seed yield per hectare. Growth
regulator at 30 ppm increased the total number of fruit harvested and
girth of fruit. Seed quality was not affected by the application of
growth regulator except 1000 seed weight. Highest net return and
B:C ratio was also obtained at 50 ppm NAA.
Seed harvesting stages significantly influenced the seed yield and
quality. Seed quality parameters like maximum 1000 seed weight,
speed of germination and seed viability were influenced by
harvesting the fruit at red ripe stage and was on par with colour
breaker stage. Seedling character like VI also recorded superior
values. Germination percentage and root length was highest in colour
breaker stage and on par with red ripe stage. Based on position of
seeds in fruit, seeds located in. the bottom portion of fruits obtained
higher values for number and weight of seeds per fruit, fruit to seed
ratio, seed yield per hectare, 1000 seed weight and speed of
germination. So to obtain good quality seeds harvesting the fruit at
red ripe stage and extracting the seeds from bottom region provide
maximum viable seeds.
