Abstract:
The present investigation was designed to study the effect of foliar application of multinutrient solution (Amrashakti) on the yield of Alphonso mango during year 2022 to 2023 at Centre of Excellence for Mango, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Ratnagiri. The compatibility study of different water soluble fertilizers was carried out and final 8 compatible and clear multinutrient solutions were formulated. Three sprays of multinutrient solution (Amrashakti) were done at bud bursting stage, flowering stage and marble or egg stage on mango to attain higher yield. To fulfill the object, total sixty uniform mango trees of variety Alphonso were selected. The experiment was conducted in Randomized Block Design with ten treatments and three replications. Two grafts were selected per treatment in each replication. Amrashakti multinutrient solution contains N, P, K, S, Cu, Zn, B and Mo. The results of the experiment revealed that the application of all the Amrashakti solutions significantly increased the yield over the Recommended dose of fertilizer. Whereas, the application of modified Amrashakti multinutrient solution @ 0.5% (Urea, SOP, each) + 0.15% (Phosphoric acid) + 0.25% (ZnSO₄, Borax, CuSO₄ each) + 0.0075% (Ammonium molybdate) along with RDF recorded significantly superior yield (5.56 t ha^-1) in comparison to rest of the treatments.
