Abstract
The experiment was conducted to study the influence of fertilizers and bioinoculants on growth characteristics of guava cv. L-49 at Fruit Research Station Imaliya, Jawaharlal Nehru Agriculture University, Jabalpur, Madhya Pradesh, during 2022-23 and 2023-24 on twelve-year-old guava trees planted at 3.0 m x 3.0 m spacing. The experiment was carried out in factorial RBD with three replications. The data revealed that different levels of nutrients and bioinoculants alone and in combinations significantly influenced the growth parameter. The maximum increase in plant height (12.16%) & (12.46%), canopy spread E-W (14.15%) & (14.45%), canopy spread N-S (14.33%) & (14.72%) and stem girth (11.19%) & (10.07%) were recorded in N2 (100%RDF), during both years of experimentation respectively. With respect of bioinoculants, the maximum plant height (11.48%) & (11.71%), canopy spread E-W (13.24%) & (13.61%), canopy spread N-S (14.05%) & (14.44%) and stem girth (9.72%) & (8.85%) were observed in B5 (Bactobooster 200 ml), during both years respectively. Among the treatment combinations, T10 (100% RDF + Bactobooster200ml) was found superior with respect of the maximum increase in plant height (12.86%) & (13.09%), in canopy spread E-W (15.77%) & (16.11%), canopy spread N-S (16.16%) & (16.66%) and in stem girth (12.54%) & (11.01%) during both the years of experimentation respectively followed by T15 (75% RDF + Bactobooster 200 ml) and minimum was recorded in control.
