Influence of Plant Growth Regulators on Growth, Yield and Yield Components in Garden Pea

Background: Garden pea is one of the most important legume crop which require proper crop management practices. Crop regulation is an important practices which enhancing the productivity of garden pea with higher economic return. This can be done by adopting proper application of PGRs. Therefore, the present study was designed to assess the effect of PGRs on growth and yield of garden pea.Methods: The present study was laid out on garden pea (Pisum sativum subsp. hortense) cv. Azad Pea-3 in a randomized block design with three replications and ten treatments comprising different levels NAA, GA3 and Salicylic acid at various stages. The data on growth and yield were recorded and analyzed statistically applying the analysis of variance technique.Result: Results revealed that the plants treated with 120 ppm gibberellic acid showed 45.39% 38.55%, 40.60% and 32.84% increment in plant height, length of pod, width of pod and number of seeds per pod and taken lowest number of days to 50% flowering over control, respectively. The use of 40 ppm NAA exhibited maximal enhancement in number of pods per plant (57.43-68.02%), seed weight per pod and Pod yield per hectare (50.62-60.26%) over remaining treatments. Conclusively, the results suggest that foliar application of PGRs favors the growth and yield of garden pea.
