Efficacy of Grace Hume-L and Nitro Bloomor-NB was studied for their potentiality to enhance yield and productivity of potato (Solanum tuberosum L.) cv. Kufri Jyoti during 2012-13 at Lohagarh, Binuria and Bahadurpur village of Bolpur-Sriniketan Block under red and lateritic agro-climatic zone of West Bengal (India). Seven different commercial formulations of plant growth regulators (PGRs) and one untreated control were taken into account with three replicates. Growth regulators showed a significant effect on improving the entire growth and yield variables of the crop. The treatment T5 (Nitro Bloomor-NB + Grace Hume-L) appeared best that influenced greatly all the growth and yield attributes of potato. The second best treatment was T2 (Nitro Bloomor-NB + Paushak) followed by T6 (Nitro Bloomor-NB) and T7 (Grace Hume-L). The percentage increased in terms of tuber yield of T5 and T2 treatment over control (T8) was 59.77 and 47.81, respectively. These combinations of growth regulators can be recommended for cultivating potato successfully with higher yield.
