Growth, yield and economics of greenhouse grown coloured capsicum as influenced by trellis system and plant spacing

Abstract

The experiment was laid out in split plot design and the treatments comprised V trellis with two stems (T1), V trellis with four stems (T2) and Spanish trellis (T3) as main plot along with three plant spacing levels, viz. S1 (40 cm × 40 cm), S2 (60 cm × 40 cm) and S3 (60 cm × 60 cm) as sub plot treatments. Results of the study showed that plant height was significantly affected by trellis, spacing and their interactions. Number of fruits/plant was highest under Spanish trellis and wider spacing (S3). Fruit weight, yield/plant and yield/square meter were observed to be significantly higher under V trellis with two and four stems as compared to Spanish trellis. Plant spacing also influenced these parameters significantly and although fruit weight and yield/plant were higher in wider spacing treatment (S3), yield per square meter was significantly higher in close spacing (S1). Economic analysis indicated that V trellis with four stems at 40 cm×40 cm spacing is optimum for more income per rupee invested for greenhouse cultivation of coloured capsicum.
