The field experiment on the performance evaluation of five leafy vegetables in naturally ventilated polyhouse in randomized block design during the rainy season (June- August 2014) revealed coriander, palak and green Amaranthus to establish and grow well with higher biomass production compared to lettuce and red Amaranthus. The modified microclimate influenced the incidence of pests and diseases and the latter affected the growth and performance of red Amaranthus and palakin the polyhouse. Reduced pigmentation was also observed in red Amaranthus. Relative yields in terms of Amaranthus proved palak to be most advantageous followed by coriander.
