Impact of rhizobium inoculation and boron application on morphological alterations and biochemical triggers in pea (Pisum sativum L.)

Rhizobium is a bacterial culture that enhances the speed of biological nitrogen fixation in association with root nodules pulse crops while boron act as catalyst for cell division hence size and sugar translocation plant. An experiment was conducted by considering rhizobium seed inoculant soil applicant two peas (Pisum sativum L.) varieties Arkel Azad Pea-3 to know morphological alterations plant height (cm), fresh dry weight g plant-1), number leaves (plant-1), days required first flowering picking. However, biochemical triggers were also observed analysis development reading (SPAD), total chlorophyll (mg g-1) derivative (chlorophyll b), protein g-1), proline content (µg both pea (Arkel Pea-3). The performance V2 superior V1 most parameters. combination + 2.0 kg ha-1 (T5) best treatment compared rest treatments V1, 1.5 (T4) V2. Among combinations, T5 T4 recorded minimum (39.3 43.0), maximum picking (75 84) highest SPAD reading, chlorophyll, noticed T4, at value varieties. b T3 50 DAS, 75 DAS. A trigger control set. positive alteration morphology changes plants due application interlink well betterment yield via increasing rate photosynthesis.
