A field experiment was conducted in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka during the period from November 2016 to March 2017 to study the performance of potato germplasm with the bio-stimulating effect of Trichoderma application on potato production. Potato germplasm viz., G1 (Sokal), G2 (Bijita), G3 (JP Blue yellow), G4 (JP Blue white), G5 (Burma-1), G6 (Burma-2), G7 (Cardinal as check), and Trichoderma application: T0 (No application), T1 (Once application), T2 (Twice application) were used in this experiment arranged in Randomized Complete Block Design with three replications. Data on different growth and yield attributes were showed significant variations. Among them, the highest plant height, maximum leaf number, SPAD value, stem number, tuber length, tuber weight observed in germplasm Sokal with twice application of Trichoderma. Maximum yield per hectare (38.92 t) were found in G1T2 and minimum (21.7 t) in G4T0. In view of overall performances, germplasm G1 with twice application of trichoderma (G1T2) has the potentiality for potato production with higher vegetative growth and yield.
