COMPARATIVE STUDIES ON THE EFFECT OF CERTAIN BIOFERTILIZERS ON GROWTH, YIELD AND QUALITY OF CARROT (DAUCUS CAROTA L.) UNDER PUNJAB CONDITIONSAnnapareddy Sharmila, Avinash Kumar, Rajkumari Asha Devi, Rupmalin Kropi and Lakshmi NarayananAbstract The investigation entitled âComparative studies on the effect of certain biofertilizers on growth, yield and quality of carrot (Daucus carota L.) under Punjab conditionsâwas 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.. |
