Abstract
A field experiment titled “Effect of inorganic input and biofertilizer on developmental phenology of Jamun (Syzygium cumini L. Skeels.) cv. Goma Priyanka” was conducted during June 2023 to December 2023 at the Fruit Instructional Farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalawar. The trial consisted of ten treatments; namely control, RDF (100, 75 and 50 %) and biofertilizer (Azospirillum and VAM at 50 g/plant each). The experiment was set up in a randomized block design (RBD) with three replicates. In a study of Jamun cv. Goma Priyanka, treatment T6, consisting of 75% recommended dose of fertilizer (RDF) combined with Azospirillum (50g/plant) and Vesicular Arbuscular Mycorrhiza (VAM) (50g/plant) outperformed other combinations of inorganic inputs and biofertilizers. The T6 treatment (75% RDF + Azospirillum @ 50g/plant + VAM @ 50g/plant) demonstrated significant improvements in both growth and physiological parameters of Jamun cv. Goma Priyanka. It enhanced plant height, canopy dimensions, leaf characteristics, petiole length, node count and girth of both rootstock and scion. Physiologically, T6 augmented key indicators such as relative water content, chlorophyll levels, photosynthesis efficiency and stomatal conductance, while lowering proline content, manifesting improved stress tolerance. Additionally, T6 improved soil physico-chemical properties by decreasing pH, electrical conductivity, bulk density, and particle density, while enhancing organic carbon content, water holding capacity, porosity, and microbial population. However, it's worth noting that treatment T3 (100% RDF + Azospirillum @ 50g/plant + VAM @ 50g/plant) was the most effective in increasing available soil N, P and K levels in the plant rhizosphere.
In summary, the T6 treatment proved as the most effective in enhancing overall plant growth, development, and physico-chemical characteristics of Jamun cv. Goma Priyanka.
