Abstract:

A field experiment was carried out during Rabi 2018-19 at College of Horticulture, Mudigere, University of Agricultural and Horticultural Sciences, Shivamogga (Karnataka) to study the influence of bioregulators on growth, tuber yield and quality parameters of sweet potato. The experiment consisted of thirteen treatments such as two concentrations of bioregulators sprayed at three frequencies (first, second and third spray at 30, 60 and 90 days after planting) and untreated control. Each treatment was replicated thrice in randomized complete block design (RCBD). The results showed that GA3 at 200 ppm (T2) recorded significantly maximum values for parameters such as vine length (176.00 cm), number of auxillary branches (5.73), number of leaves per plant (391.33), vine internodal length (6.03 cm) and vine girth (17.80 mm). Even maximum tuber yield per plant (835.83 g), tuber yield per plot (30.09 kg), tuber yield per hectare (46.44 t) and maximum total sugars (2.25 %) were noticed in T2 (GA3 at 200 ppm) in Sweet potato.
