Abstract
Capsicum (Capsicum annuum L. var. grossum Sendt; 2n =24) also known as Bell pepper or Sweet pepper or Green pepper or Shimla mirch. The genus capsicum belongs to the family Solanaceae which is grown in several part of the world and is believed to be native of Tropical South America. An experiment was carried out to study the effect of planting geometry and number of shoots on quality and yield of capsicum cv. Buffalo under naturally ventilated Poly house during Rabi, 2016 at Hi-Tech Horticulture, Dr. RPCAU, Pusa.
There were three spacings viz., 45 cm × 30 cm (4.4 plants/m2), 45 cm × 45 cm (2.94 plants/m2) and 45 cm × 60 cm (2.22 plants/m2) and three levels of number of shoots per plant viz., two shoots, three shoots and four shoots. The experiment was laid out into Factorial randomize block design, with three replications.
Among the different spacing tried, the maximum spacing 45 cm × 60 cm recorded significantly higher fruit length (9.41 cm), fruit breadth (7.26 cm), fruit weight (185.31 g), fruit volume (299.60 cc), shelf life (7.18 days), rind thickness (0.74 cm), number of fruits (18.48/plant) and fruit yield (3.38 kg/plant). The maximum fruit yield (82.13 t/ha) was recorded under spacing 45 cm × 30 cm.
With regards to the number of shoots per plant, the treatment two shoots per plant recorded significantly higher fruit length (9.30cm), fruit breadth (7.03 cm), fruit weight (175.91 g) fruit volume (309.80 cc), rind thickness (0.73 cm) and shelf life (7.11 days). Whereas retaining four shoots per plant recorded significantly higher number of fruits (20.31/plant), fruit yield (3.20 kg/plant), and fruit yield (95.01 t/ha). Over all treatment combination S2 (45 cm x 45 cm) with training P3 (four shoots) levels can be adopted for higher yield with better quality of capsicum fruit as well as maximum benefit cast ratio and higher net return.
