Leaf nutrient status of a few selections and cultivars of walnut

An experiment was conducted to study the leaf nutrient status in some cultivars of walnut planted in experimental orchard at Solan Himachal Pradesh to facilitate scheduling of fertilizer application. Considerable variation for foliar macronutrients and micronutrients level was found among walnut selections and varieties. Cultivar “Paynee” was found to have maximum leaf nitrogen (2.79%), phosphorus (0.28%), leaf iron content (123.7 ppm) and minimum copper (4.08 ppm) content. Leaf manganese content was maximum (53.48 ppm) in cultivar “Hartley” while “Local selection 2” recorded the minimum leaf manganese content (51.86 ppm). “Ronde de Montignac” was reported to have maximum leaf copper content (4.26 ppm).
