A field experiment was carried out during the years 2020-21 and 2021-22 in the experimental orchard of CCSHAU, Hisar to study the effect of farmyard manure and biofertilizers with RDF on leaf nutrient content of pomegranate cv. Bhagwa. Twenty two treatments were arranged in a randomized complete block design with three replicates. The main challenge of plant nutrient may be to increase the width of the domain between the access and excess frontiers rather than to define a single economic optimum point. The leaf analysis offers the most accurate and reliable diagnostic tool for examining the nutritional status of trees. Results revealed different fertilizer combination significantly enhanced leaf nitrogen, phosphorus, potassium content due to farmyard manure and biofertilizers application. Also, farmyard manure and biofertilizers could compensate for the 25% reduction of chemical fertilizers. Therefore, treatment T14-RDF 75% + FYM + Azotobacter + PSB is recommended for growers. This treatment gave best result by increasing the nutritional status of the plant through the beneficial effects of organic and biofertilizers which enhanced the availability of nutrients in the soil.

From the present investigation it is inferred that integration of organic manures and biofertilizers and RDF had significant effect on Leaf NPK content during both years. Different integrated treatments failed to significantly affect leaf micronutrient content i.e. MN, Zn, Fe. However, values increased during second year of experimentation.
