Abstract

Production of reasonable head yield is a challenge for the organic lettuce growers. An attempt had been made to increase lettuce head yield and quality by intervening biofertilizer’s seedling root dipping and foliar spray of biostimulants along with basal organic manure. Field investigations were conducted at UBKV, Pundibari, Cooch Behar,West Bengal, India during November to February of 2014-2015 and 2015-2016 by evaluating thirteen treatment combinations replicated thrice in randomized block design. Results revealed that significantly higher plant height (20.25 cm), number of non-wrapper leaves (11.60), ascorbic acid content (6.24 mg/100g) were recorded by the application of vermicompost (6 t/ha) as basal along with seedling root dipping with Azophos biofertilizer and foliar spray of seaweed extract. However, the maximum head weight (436.98 g/plant) and yield (30.59 t/ha) as well as vitamin A content (370.63 IU/100g) were observed in the treatment containing basal application of vermicompost (6 t/ha) along with seedling root dipping with Azophos biofertilizer and foliar spray of humic acid.
