A field experiment was conducted to know the production potential of buckwheat (Fagopyrum esculentum Moench) as influenced by genotypes and fertilizer levels in Northern Transition Zone of Karnataka was carried out at Main Agriculture Research Station, University of Agricultural Sciences, Dharwad, Karnataka during kharif 2017. The experiment was laid out in split plot design with three replications comprising of twenty-four treatment combinations. The treatment includes two genotypes viz., G1: IC-79147 and G2: PRB-1 as main plots with twelve fertilizer levels (N: P2O5: K2O kg ha-1) viz., F1: 20: 10: 0, F2: 20: 10: 10, F3: 20: 20: 0, F4: 20: 20: 10, F5: 40: 10: 0, F6: 40: 10: 10, F7: 40: 20: 0, F8: 40: 20: 10, F9: 60: 10: 0, F10: 60: 10: 10, F11: 60: 20: 0, F12: 60: 20: 10 as subplots. The results revealed that genotype IC-79147 recorded significantly higher seed yield (8.07 q ha-1). Among the fertilizer levels, application of 60: 20: 10 kg N: P2O5: K2O kg ha-1 was recorded significantly higher seed (8.47 q ha-1) and straw yield (19.23 q ha-1). The genotype IC-79147 with application of 60: 20: 10 kg N: P2O5: K2O kg ha-1 recorded significantly higher seed yield (9.43 q ha-1) and yield attributes viz., number of clusters per plant (7.21), seeds per cluster (10.17), 1000 seed weight (25.71 g),as well as net returns ( 30,090 ha-1) and BC ratio (3.11), which was on par with application of F10 and F11 fertilizer levels along with IC-79147 genotype. PRB-1 genotype with 60: 20: 10 kg N: P2O5: K2O kg ha-1 fertility level recorded significantly higher straw yield (17.01 q ha-1) and growth attributes viz., plant height (102.6 cm), total dry matter production per plant (8.55 g), LAI (2.15) and number of branches per plant (9.64) at harvest, which was on par with PRB-1 genotype along with F10 and F11 fertility levels as compared to other interactions.
