Influence of post flowering foliar nutrient application on yield and quality attributes of mango (Mangifera indica L.) cv. Alphonso under south Konkan conditions

Abstract

The experiment conducted at Mango Research Sub-Centre, Rameshwar, Tal. Deogad, Dist. Sindhudurg (Maharashtra) during the year 2015-16 to assess the influence of post flowering sprays of nutrients. viz; Urea (2%) NPK 19 : 19 : 19 – (1%), potassium nitrate (2%), potassium sulphate (0.5%) and monopotassium phosphate (0.5%) with an untreated control revealed highest fruit retention (8.05 per cent) with the potassium nitrate application against the lowest (93.85 per cent) registered in control. The fruit yield was also significantly maximum (127 fruits tree-1, 29.13 kg tree-1 and 2.91 t ha-1) with the potassium nitrate treatment registering an increase in yield by 38.57 per cent than the control. The maximum fruit weight (233.8 g) was recorded in control (T6). The lowest intensity (10.0 per cent) was observed with potassium nitrate and potassium sulphate sprays.
