Abstract
An experiment was conducted during the off-season 2013 at the Research Farm of
Department of Agricultural Engineering, College of Agriculture, CSK Himachal Pradesh
Krishi Vishvavidyalaya, Palampur, to study the effect of spacing and training system on
productivity of capsicum under naturally ventilated polyhouse. The experiment was laid
out in Factorial Randomized Block Design with three replications, consisting of nine
treatments i.e. three plant spacings (30 cm x 45 cm, 45 cm x 45 cm and 60 cm x 45 cm)
and three training systems (two shoots, three shoots and unpruned). Plants grown at
wider spacing of 60 cm x 45 cm took significantly lesser number of days for flower
initiation (35.6 days), 50 per cent flowering (41.4 days), fruit setting (50.3 days) and days
to first picking (68.6 days) than intermediate an narrow spacing. Wider spacing (60 cm x
45 cm) also recorded significantly higher fruit length (8.2 cm), fruit breadth (7.8 cm),
fruit weight (92.7 g), shelf life (8.6 days), pericarp thickness (0.78 cm), number of fruits
per plant (21.1) and fruit yield per plant (1.8 kg) than other two spacings. The maximum
fruit yield (844.0kg/100m2) was recorded under closer spacing of 30 cm x 45 cm. With
regards to the number of shoots per plant, the treatment two shoots per plant recorded
significantly higher fruit length (8.3 cm), fruit breadth (7.7 cm), fruit weight (92.4 g),
pericarp thickness (0.79 cm), shelf life (8.5 days) and ascorbic acid content
(86mg/100g).Where as retaining three shoots per plant recorded significantly higher fruit
yield per plant (1.76 kg) and fruit yield (855.0kg/100m2). Plants spaced at 30 cm x 45 cm
and trained to three shoots registered maximum net returns and benefit: cost ratio
(Rs.16525 and 1.39) followed by three shoot plants grown at 45 cm x 45 cm spacing
(Rs.15369 and 1.31). The lowest net returns and benefit: cost ratio (Rs.8184 and 0.71)
were registered from unpruned plants spaced at 60 cm x 45 cm.
