Study on vegetative attributes and yield components of mungbean (Vigna radiata L. Wilczek) influenced by plant growth regulators

The use of Plant Growth Regulators (PGRs) has opened up fresh opportunities for enhanced seed production in pulses in particular which are often face limitations due to intrinsic and external factors. Therefore, an experiment was carried out inside the net house in cement moulded pots to determine the effect of crop growth regulators viz. Maleic Hydrazide, Gibberellin, Triacontanol, 2,3,5- triiodobenzoic acid and Cycocel, as foliar spray. The result indicated significant variations in foliage, canopy structure, floral initiation, pod setting, seeds per plants etc., due to plant growth regulators. These changes translated finally to the yield attributes. The results of the study concluded that productivity and Biological yield per plant was the highest among all treatments in case of 20 ppm TIBA, although H.I. was highest in CCC 100 ppm. These results suggest that utilization of plant growth regulator might serve us a means of improving yield of mung bean. This investigation also indicated that if a new growth inhibitor were to be recognized, which could control excess vegetative growth without negative. Effects on reproductive development, seed yield in mung bean, it could also possibly be improved by combining a growth inhibitor such as TIBA with growth promoter at a specific developmental stage. | Study on vegetative attributes and yield components of mungbean (Vigna radiata L.
