Effect of spacing and training levels on growth and yield of capsicum under polyhouse in North-Bihar conditions

An experiment was carried out to study the effect of spacing and number of shoots on growth and yield of capsicum variety Indira under poly house during 2009–10 and 2010–11 at polyhouse unit, Department of Horticulture, Tirhut College of Agriculture, Dholi, Muzaffarpur, Bihar. There werethree levels of spacing 45 x 30 cm (4.4 plants/m²), 45 x 45 cm (2.94 plants/m²) and 45 x 60 cm (2.22 plants/m²) and thre elevels of numbers of shoots per plant viz. two shoots, three shoots and four shoots. The experiment was laid out infactorial randomized block design with three replications. Among the different spacing, S1 (45 x 30 cm) spacing recorded significantly higher plant height (147.21 cm.) than the other spacing but spacing S3 (45 x 60 cm) recorded significantly higher number of leaves per plant (105.67), number of flowers per plant (13.03), number of fruits per plant (9.65) but the maximum fruit yield (71.39t/ha) was recorded under spacing S1 (45 x 30 cm) with regards to the number of shoots per plant. The treatment two shoot per plant recorded significantly higher plant height (144.36 cm), number of leaves (116.25) whereas retaining four shoots per plant recorded significantly higher number of flowers per plant(13.04), number of fruit per plant (9.30), fruit yield (65.35t/ha). But for the common farmers growing capsicum cv. Indira with closer spacing S1 (45 x 30 cm) and training level (four shoots per plants) will be more profitable under polyhouse.
