Effect of Organic Manures and Fertility Levels (NPK) on Leaf Mineral Composition of Ber under Semi-arid Condition


Raj Bala Choudhary, OP Garhwal

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.
