Healthy growth and yield of pulse crop depend on many factors, in which one of them is morphological
growth of roots including number of root nodules. Keeping in view, an experiment was conducted to
explore the impact of Rhizobium inoculation and boron application on root morphology, growth, yield and
yield attributes in pea. The results obtained from the study showed that morphological growth of roots
like root length (cm), root volume (cm3) and root nodules/plant were positively influenced with the
treatments and gradually increased as the amount of boron in combination with Rhizobium increased up
to 2 kg/ha as compared to control. The best performance related to root morphological characters over
control was recorded in T5 followed by T4 > T3 > T2 > T1
as compared to control T0 in V1, while T4 was recorded best in V2
. The response of treatments with respect to yield and yield attributes was same as morphological
growth of root in both the varieties. Comparative analysis among the best varieties showed that V2
performed well for most of the parameters as compared to V1 except to root length.
