An experiment was carried out to access the effect of plant growth regulators (PGRs) on biomass, number of nodes, internodal length and leaf water relative content of Fagopyrum esculentum. Four major hormones: Indole Acetic Acid (IAA), Benzylaminopurine (BAP), Abscisic Acid (ABA) and Gibberellic Acid (GA) were used in combinations i.e. IAA+BAP, IAA+ABA, IAA+GA, ABA+BAP, BAP+GA and ABA+GA in concentration of 25, 50 and 100 mg l-1 through foliar spray. Results revealed that higher concentration of IAA+BAP (50 and 100 mg l-1) enhanced number of nodes and shoot fresh weight. Combination of BAP+GA at 100 mg l-1 concentration enhanced shoot fresh and dry weight. Root fresh and dry weight was improved in IAA+GA 100 mg l-1 treatment. Maximum relative water content was observed at 50 mg l-1 of ABA+GA concentration. No. of nodes and internodal length decreased in plants treated with ABA+GA (25 mg l-1). Combination of ABA+BAP at 25 mg l-1 concentration reduced internodal length and 100 mg l-1 affected root fresh as well dry weight. 25 mg l-1 concentration of BAP+GA lowered leaf relative water content, root fresh and dry weight. ABA in combination with IAA (ABA+IAA) at 25 mg l-1 negatively affected shoot fresh as well as dry weight.

Present investigation was made to evaluate effect of PGRs on shoot and root length of Fagopyrum esculentum. Results revealed that there was increase in shoot length by GA at 100 mg l-1 and root length by IAA at 50 mg l-1 at 30, 60 and 90 days of plant growth. ABA at 25 mg l-1 and 100 mg l-1 decreased shoot length as well root length. BAP at 100 mg l-1 also decreased root length. In combinations, IAA+GA 100 mg l-1 treatment enhanced shoot length as well as root length. Decrease in shoot length was observed in IAA+ABA, ABA+BAP (50 and 100 mg l-1) and root length by ABA+BAP (100 mg l-1) treatment.
