| Abstract:
Flordasun cultivar of peach budded on plum, peach and self rooted cuttings were planted at a spacing of 2.0x0.5 m, 2.0x0.75 m and 2.0x1.25 m with different drip irrigation levels with discharge rate 1, 2 and 3 litre per day. It was observed that wider the spacing, more was the nitrogen, phosphorus and potassium content of leaves. Higher irrigation levels also increased the nitrogen, phosphorus and potassium content of leaves. Peach on plum exhibited lowest N, P, K content irrespective of spacing and irrigation levels. Maximum nitrogen content was recorded in treatment combinations of 2.0x1.25 m and 3 litre/day (2.55%) in peach cuttings and minimum in 2.0x0.5 m and 1 litre/day (1.58%) in plum rootstock. Maximum P content (0.253%) was recorded in the treatment combination of 2.0x1.25 m and 3 litres/day in peach on peach. Treatment combination of 2.0x1.25 m and 3 litres/day showed maximum K content (2.32%) in peach on peach. | |
