Abstract:
A field trial was conducted during 2015-16 at the experimental field of Division of Fruit Science Sher-e-Kashmir University of Agricultural Sciences and Technology. The trail was conducted to observe the effects of Nitrogen, Phosphorus and Potassium on available nutrients, which consisted of 10 treatment combinations with different levels of Nitrogen, Phosphorus and Potassium. Investigation revealed that highest available nitrogen (311.6 kg ha
-1) was recorded in T
4 treatment with 105g N, 35g P
2O
5 and 150g K
2O. Highest available phosphorus (21.08 kg ha
-1) was recorded in T
7 treatment with 85g N, 45g P
2O
5 and 150g K
2O. Highest available potassium (248.44 kg ha
-1) was recorded in T
10 treatment with 85g N, 35g P
2O
5 and 180g K
2O. Highest exchangeable calcium (588.33 ppm) was recorded in T
4 treatment with 105% N, 35g P
2O
5 and 150g K
2O. Highest exchangeable magnesium (131.88 ppm) was recorded with 85g N, 35g P
2O
5 and 150g K
2O (T
3 treatment). Highest available sulphur (10.99 ppm), highest available zinc (0.76 ppm), highest soil copper (1.24 ppm), highest available manganese (19.99 ppm), highest available iron (36.81 ppm) was recorded in T
4 treatment with 105g N, 35g P
2O
5 and 150g K
2O.
