Abstract:

The trial was laid out during three consecutive year i.e, 2013-14, 2014-15, 2015-16 to show the effect of fertigation on growth, yield and physiology in Kinnow mandarin under high density planting. Result of three years pooled data on growth parameters showed that increase in current season shoot (8.52 cm), leaf area (27.34 cm2), leaf area index (7.99), increase in plant height (82.23 cm), trunk girth (6.32 cm), canopy volume (57.97 cm3) and yield (16.93 Kg/plant) were higher under higher doses of fertigation i.e. 120 % RDF followed by 100 % RDF. Physiological observations like total chlorophyll content (3.60 mg/100g), photosynthetic rate (7.19 µmol CO2 m-2 sec-1), stomatal conductance (0.38 (mmol m-² s-¹), total transpiration rate (5.82 µmol H2O m-2 sec-1) and leaf internal CO2 concentration (332.00 ppm) were also recorded higher under higher doses of fertigation. Yield (22.61 ton hac-1) was also observed under higher dose of fertilizer. However, all essential nutrients (macro & micro) influence low yield which may improve by the application of balanced dose of fertilizer in split through fertigation.
