Enhancement of leaf nitrogen,phosphorus and potassium and seed protein in Vigna radiata by pyridoxine application

Soaking the seeds of mungbean (Vigna radiata L. Wilczek cv. K-851) in pyridoxine solution significantly enhanced leaf N, P and K concentrations at different growth stages, and seed protein concentration at harvest. Leaf N, P and K were significantly correlated with root length and seed protein. Thus, pyridoxine application not only enhanced the availability of nutrients to plants but also was responsible for the maintenance of a favourable source-sink relationship, thus ensuring more nutritious seeds of mungbean.
