A field experiment was carried out during 2015-2016 to determine the effect of organic manures and fertility levels (NPK) on leaf mineral composition of three year old ber plants. Four levels of organic manures (control, FYM @ 20 kg/plant, vermicompost @ 6 kg/plant and poultry manure @ 8 kg/plant) and five levels of RDF (control, 50% RDF, 75% RDF, 100% RDF and 125% RDF) in Randomized Block Design with three replications to balance fertilizer requirement of ber under semi-arid region of northern India. The application of vermicompost @ 6 kg per plant (M₂) among the different organic manures proved significantly superior over rest of the treatments in respect to leaf nitrogen (2.25 %), phosphorus (0.119 %) and potassium (1.73 %) content, RLWC (64.11 %) and chlorophyll content (1.84 mg/100g). Similarly, results also showed that maximum leaf nitrogen (2.30 %), phosphorus (1.120 %) and potassium (1.79 %) content, RLWC (65.91 %) and chlorophyll content (1.87 mg/100g) were noted with treatment 125 per cent RDF (F₄) which was statistically at par with 100 per cent RDF (F₃) as compared to control, 50 per cent and 75 per cent of RDF.
