“Effect of growth regulator IAA on Vigna radiata L. (Green gram)”

The present study deals with the experiment on green gram Vigna radiata L. belonging to family Fabaceae. Contribution of mung to agriculture and daily life has been tremendous, thus to improve the yield of such nutritious pulse crop an attempt is made. For this, tray experiment was conducted. Healthy seeds of mung bean are taken and treated with growth regulator Indole-Acetic acid (IAA) in different concentrations compared with control. The growth parameter like days of germination, development of cotyledons, number of leaflets in (day- 4days,6days,8days) height of plants, maximum leaf length, weight of seeds ,number of seeds per pod etc. The results revealed that highest concentration of IAA gave better results, and 50% & 25% IAA helped to some extent improve yield of crop.
