Effect of different organic manures on vegetative growth of mango (Mangifera indica L.) var. Amrapali

Abstract

The present field experiment entitled “Effect of different organic manures on vegetative growth of Mango (Mangifera indica L.) var. Amrapali” was carried out at the horticulture farm of Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj during the year 2024-25 to study the performance of different varieties for vegetative growth, reproductive growth, fruit physical parameters, yield parameters, quality of fruits and organoleptic parameters under high density planting. The experiment comprised of 7 (6 + 1) treatments with 03 replications in randomized block design. A field experiment was conducted to evaluate the impact of various nutrient management treatments on the vegetative and physiological growth parameters of the Amrapali mango cultivar. The study included different combinations of organic and inorganic fertilizers, with a focus on plant height, stem girth, plant spread, number of branches and leaves, leaf area index, chlorophyll content, and survival percentage. Among the treatments, T6 (FYM + Recommended Dose of Fertilizers (RDF) + Vermicompost) consistently recorded the highest values for all observed parameters. Maximum plant height (1.26 m), stem girth (3.84 cm), number of branches (1.27), plant spread (48.07 cm N-S and 53.51 cm E-W), number of leaves (97), leaf area index (58.67), chlorophyll content (41.37), and survival percentage (93.33%) were recorded under T6. The second-best performance was observed under T5 (Compost + RDF), while the control treatment T0 recorded the lowest values across all parameters. These results indicate that the integrated application of FYM, RDF, and vermicompost is the most effective treatment for improving the growth, physiological health, and survival of Amrapali mango plants.
