The present study was conducted to compare the effects of natural and chemical farming system of apple production on soil, leaf nutrient status and fruit quality. Experiment was conducted in ten commercial apple orchards; five under natural farming system of apple production and adjacent to them, five were under chemical farming system of apple production for comparison. Leaf nutrient status, soil physio-chemical properties and fruit quality under both the farming systems were evaluated. The

Among micronutrients, status of Cu and Zn were recorded to be significantly different in both the farming systems whereas, Fe and Mn were recorded to be non-significant. Soil pH and EC were recorded to be higher (6.12, 0.48 dS m− 1) in CFS than NFS (5.77, 0.38 dS m− 1), while OC was reported to be higher (2.03%) in NFS than CFS (1.78%). However, only OC was found to be significant. Fruit length, breath, weight and TSS showed significant difference in both the farming systems. Mean fruit length, breadth, weight, and acidity was recorded to be higher (65.80 mm, 71.62 mm, 159.65 g, 0.64%) in CFS than NFS (58.87 mm, 62.72 mm, 122.41 g, 0.48%). While firmness and TSS were recorded to be higher (6.95 kg inch− 2, 12.27 ᵒBrix) in NFS than CFS (5.64 kg inch− 2, 10.91 ᵒBrix). It can be concluded that nutrient status of soils and leaves was higher in CFS. This may be due to small sample size studied and the orchardists selected were practicing natural farming from only 4 years.
