| dc.description.abstract | A pot culture experiment was conducted at the Farming Systems Research Station, Kottarakkara to study the influence of NPK fertilizers under different light intensities on the growth yield and quality of bush pepper. The treatments included three levels of light (100, 75 and 50 per cent) three levels of each of N, P (25, 37.5 and 50 g bush-1) and K (50, 75, 100 g bush-1). The experiment was laid out in split plot design with three replications. Light intensities showed profound influence on the length and number of primary and secondary branches, number of leaves, leaf area, chlorophyll content of leaves, internodal length and drymatter production. Best expression of all these characters was under 50 per cent light. All these characters showed a-declining trend as light intensity increased from 50 per cent to 100 per cent light. In the open condition better expression of all growth characters were observed from low to medium level of nitrogen and phosphorus (25 to 37.5 g bush-1). Under 75 per cent light better expression of all growth characters was at medium level of N(37.5 g bush-1), K (75 g bush-1) and lowest level of P (25 g bush-1). Under 50 per cent light response to N levels was not consistent for different growth parameters. The plant showed positive response to P and K from medium to highest level (37.5 to 50 g bush-1). Earlier flowering was observed at 50 per cent light. Under all levels of light higher levels of N delayed flowering, but incremental doses of P induced early flowering. Dry matter production at all light intensities was more in low to medium levels of nutrients. Yield and yield attributes were not influenced by light intensities. However maximum berry yield was recorded under 50 per cent light with 37.5 g N and 37.5 g P bush-1. Under 100 and 75 per cent light also maximum yield was recorded by plants receiving 37.5 g each of N and P bush-1. Quality of the produce was not significantly influenced by the varying light levels. N levels had significant effect on the volatile oil content and P levels on oleoresin content. Maximum uptake .of all the nutrients was observed under 450 per cent light. There was a steady increase in the uptake of all the nutrients with increasing dose of the three nutrients. Under 100 per cent and 75 per cent light maximum uptake was from medium to high level of the nutrients. | en_US |
