INFLUENCE OF TRAINING SYSTEMS ON QUANTITATIVE TRAITS OF BELL PEPPER CULTIVARS GROWN UNDER PROTECTED ENVIRONMENT
SARVPRIYA SINGH
Abstract
Abstract Yield and quality traits under polyhouse cultivation is greatly influenced by different training systems. Studies was conducted on effect of training on physical parameters of three coloured bell pepper cultivars viz. Indra (green), Inspiration (red) and Bachata (yellow) during 2018-19 and 2019-20 under naturally ventilated polyhouse. Amongst cultivars, Indra obtained maximum plant height. Whilst Bachata was having early flowering, thickest fruit rind with a moderate shelf life. Indra was best in shelf life. The results revealed that the plants trained on two shoots attained significantly maximum height whereas the untrained plants remained bushy in nature. Plants trained on two shoots took least days for first flower initiation. Whereas, untrained plants took comparatively maximum number of days. An opposite behaviour was observed in days to first fruit harvest as the fruits of plants trained on two shoots took more number of days in attaining fruit size. Plants trained on two shoots have maximum fruit size, weight, rind thickness and shelf life of fruits and produced minimum number of fruits whereas vice versa in case of untrained plants. Plants trained on four shoot system resulted in maximum fruit yield/ m2 amongst the cultivars. But the fruits obtained from plants trained on two shoots were found to best in qualitative traits. An increased B:C ratio of 1.61, 1.59 and 1.39 in Bachata, Inspiration and Indra, respectively was observed when the plants were trained on two shoots. The result concludes that plant trained on two shoot in yellow color cultivar gives maximum profit per unit area.
