The field experiment was conducted to study the Effect of Fertigation scheduling for growth, yield and quality of mango, cv. Langra (25-years-old) in Kymore plateau of Madhya Pradesh during 2019-21 under All India Coordinated Research Project on Fruits with the objectives to improve fruit yield and quality of Mango to get more returns per unit area from mango orchard in response to fertigation. To standardize the fertigation method in Mango orchard. The experiment was laid out in RBD comprising with five replications. Data were recorded on plant height, canopy volume, stem girth, tree spread, number of fruit, fruit weight, yield/tree, yield/ha and benefit: cost ratio of different fertigation treatments. The treatments were namely, T1 Control as per RDF (after harvest) in basin after harvest; T2 : (N 40%, P 60%, K 20% after harvest; N 40% P 40%, K 20% during fruit set and N 20%, K 60% at marble size); T3 (N 25%, P 50%, K 15% after harvest; N 20%, P 25%, K 15% during fruit set ; N 30%, K 45% at marble size); T4 (N 20%, P 30%, K 10% after harvest; N 20%, P 20%, K 10% during fruit set ; N 10%, K 30% at marble size) and T5 (N 10%, P 20%, K 5% after harvest; N 10%, P 5%, K 5% during fruit set ; N 5%, K 15% at marble size). Two years of response study revealed that maximum plant height (7.66m), canopy volume (737.43m3) and tree spread (9.93 m N- S and 10.18m E-W) were registered with treatment T5. However, the highest number of fruits (247.50) was recorded with treatment T4, while maximum fruit weight (231.0g) was recorded with treatment T3. The maximum fruit yield (53.60kg/tree) was registered with treatment T3. The maximum total soluble solids (TSS) was recorded (21.800B) with treatment T3. These results, though varied quite considerably, but best treatment was adjudged as treatment T3, to be supplemented with fertigation.
