Abstract
The present investigation was conducted during Kharif, 2015 at Research Block,
Department of Vegetable Science and Seed Testing Laboratory at Department of Seed Science and
Technology, V. C. S. G. Uttarakhand University of Horticulture and Forestry, College of Forestry,
Ranichauri Campus. The experiment was laid out in Randomized Block Design (Factorial) in the field
and Completely Randomized Block Design (Factorial) in the laboratory. The cultivar ‘PRC-1’ was
used in the different treatment combinations comprised of three canopy system viz., T1 (two branch),
T2 (three branch), T3 (four branch) and planting distance viz., S1 (45x45 cm), S2 (45x60 cm) and S3
(50x50 cm) and S4 (60x60 cm). The observations were recorded in the field are plant height (cm),
fruit weight (g), and fruit width (mm), number of fruits/plant, number of seeds/fruit, seed yield/plant
(g), seed yield (Kg)/ha, 1000 seed weight (g). While the observations recorded in the laboratory were
germination (%), Shoot length (cm), root length (cm), seedling length (cm), seedling fresh weight (g),
seedling dry weight (g), seedling vigor index-I & II.
All the characters showed significant differences, among them treatment combinations, S4T1
(60×60 cm and two branches) showed minimum days to 50% flowering and higher plant height and
number of seed per fruit. From the present study it can be concluded that the treatment combination
S3T2 (50×50 cm and three branches) was found better for seed yield (kg) per hectare whereas, S4T1
(60×60 cm and two branches) was superior for seed quality attributes such as 1000 seed weight,
germination and seedling vigour. Therefore, the canopy system T2 (three branches) in combination
with planting distance S3 (50×50 cm) may be suggested to get higher seed yield (kg)/ hectare and for
higher production of seed yield/plant.
