The present investigation entitled “Effect of chemicals on growth, yield and quality of elephant foot yam” was carried out at AICRP on Tuber Crops, Regional Horticultural Research Station, Navsari Agricultural University, Navsari (Gujarat) during the year 2017-18. The experiment was conducted in Randomized Block Design (RBD) with three replications and eleven treatments consisting of different chemicals (Thiourea: 200 and 300 ppm; KNO3: 500 and 750 ppm; GA3: 100 and 200 ppm; CCC: 50 and 75 ppm; MH: 250 and 500 ppm and water soaked i.e. control) with different concentrations. The setts of 250 g (± 50 g) were soaked in the solution for one hour as per the treatments. Among all soaking treatments, Thiourea 200 ppm was found most effective in days required for first emergence (20.00 days), plant height at 120 and 150 DAP (63.73 cm and 63.29 cm, respectively), culm girth at 120 and 150 DAP (15.57cm and 16.29 cm, respectively), petiole length at 120 and 150 DAP (52.80 cm and 53.67 cm, respectively), number of leaflets per plant at 90 and 150 DAP (297.53 and 311.93, respectively). Yield attributes viz., corm diameter (14.82 cm), corm yield per plant (1.315 kg), yield per net plot (17.367 kg) and yield per hectare (30.15 t) were also recorded highest in T1 treatment whereas, maximum number of cormels (3.13) per corm were found in T3 (KNO3 500 ppm) treatment. Quality attributes viz., dry matter content (32.60 %) and beta-carotene (Vitamin-A) content (147.13 IU) were found maximum in T2 treatment whereas, the highest starch content (17.80 %) was found in T1 treatment. Lowest amount of calcium oxalate content (0.0200 %) was found in T10 (MH - 500 ppm) treatment.
