Abstract
The investigation entitled ââ¬ÅComparative studies on the effect of certain biofertilizers on growth, yield and quality of carrot (Daucus carota L.) under Punjab conditionsââ¬Âwas carried out at vegetable research farm, Lovely Professional University, Phagwara, Punjab during Rabi 2021-2022. The experimental design adopted was two factorial RBD with three replications. The first factor was biofertilizers and second factor, carrot cv. Country Red and Lalima. The experiment included 8 treatment combinations viz. Azospirillum+50% RDF, PSB+50% RDF, VAM+50% RDF, Azospirillum +PSB+50% RDF, Azospirillum +VAM+50% RDF, PSB +VAM+50% RDF, Azospirillum +VAM+PSB+50%RDF, Control 100% RDF. Among the interaction effects the combination of 50% RDF+ PSB + Azospirillum + VAM recorded highest values in terms of growth characters viz., plant height (87.82 cm), number of leaves (19.74), fresh and dry weight of root (124.91 g and 4.72 g, respectively) and yield characters viz., root length (27.33 cm), yield per plot (5.82 kg/ plot) and yield per hectare (194 q/ha), and quality characters viz. carotene content (47.39 mg), total soluble solids showed better performance with application of Azospirillum and 50% RDF and on other hand ascorbic acid found superior in the combination (Azospirillum + VAM + 50% RDF), respectively..
