Abstract
A field experiment was conducted during 2019-20 to study “stage wise fertigation scheduling for high density planting in mango (Mangifera indica L.) mango cv. Mallika” at experimental farm of the Department of Fruit Science, College of Horticulture and Forestry, Neri, Hamirpur (HP).The investigation comprised of seven treatments involving drip fertigation at 100, 90, 80, 70 and 60 per cent recommended fertilizer dose, treatment T6 (recommended dose of fertilizer and manure) and treatment T7 (control- in which no fertilizer was applied). The result of experimentation revealed that drip fertigation produced significant effect tree height (1.48 m), annual shoot extension growth (38.6 cm) and leaf area (85.6 cm2) were obsereved under T1 (100 % of RDF). Trunk cross sectional area (cm2) and canopy spread (m) not produced any significant effect on different level of fertigation. The maximum fruit set (4.4 %), fruit retention (9.0 %) and yield (14.1 kg/tree) were recorded in treatment T1 (100 % of RDF). Further fruit physical parameter like fruit weight (358 g), length (12.5 cm), width (7.5 cm) as well as fruit chemical parameter like TSS ( 23.0oB), titratable acidity (0.233 %), reducing sugars (5.1%), non-reducing sugars (12.7 %), total sugars (18.3%) and maximum leaf N (1.47 %), P (0.200 %) and K (0.71 %) were also recorded maximum in treatment T1.(100 % of RDF). However the treatment was found to be statistically at par with treatment T3 (80 % of RDF) for all above mentioned parameters. To sum up, it can be derived from these studies that fertigation at 80 per cent recommended dose of fertilizers was the most effective method for mango cv. Mallika.
