The field experiment was conducted during 2013 at Sriniketan and Bahadurpur village of Birbhum district under red and lateritic agro-climatic zone of West Bengal to evaluate the bio-efficacy of Grace Hume-L (based on Humic acid 12% w/w) and Nitro Bloomer-NB (based on Nitro Benzene 35% v/v) for sustainable production of lady’s finger (Abelmoschus esculentus L.) on two widely cultivated and popular varieties, Arka Anamika and Parbhani Kranti. The experiment was laid out in RBD having seven treatments including one control with three replications. First observation was taken at seven days before first spraying and subsequently upto final harvesting. Ten plants in each replication were randomly selected and tagged for recording growth and yield parameters at 30, 60 and 90 days after sowing. Application of Grace Hume-L at 2 ml/l or Nitro Bloomor-NB at 1.5 ml/l twice (4 and 8 weeks after sowing) proved better for greater production, and yielded 40% more than the control plot irrespective of varieties taken under the study. Farmers may choose these growth regulators for improving crop health and enhancing productivity.
