Abstract
A field experiment was carried out the experimental findings indicated that legume root-nodules fix substantial amount of nitrogen under field conditions. Root-nodulation studies indicated that all the plant growth regulator were found significantly superior to control (no growth regulator) with respect to root-nodule formation. Amongst the growth regulators, triacontanols i.e. Vipul, TATA, Miraculan and N-triacontanol (Grocel) and NAA performed the best in ancouraging higher number of root-nodules/plant. Field experiment was conducted in the department of crop physiology at Vindhya Science & Agricultural Research Institute, Raushar, Rewa (M.P.) during 2019 to 2020.
