Abstract

A two year investigation was conducted at Krishi Vigyan Kendra (ICAR- VPKAS), Kafligair- Bageshwar during 2016 and 2017 in peach cv. RED JUNE with ten treatments viz., 375 g N per tree + 0.5 % CaCl₂ (T₁), 375 g N tree^-1 + 1.0 % CaCl₂ (T₂), 375 g N tree^-1 + 1.5 % CaCl₂ (T₃), 500 g N tree^-1 + 0.5 % CaCl₂ (T₄), 500 g N tree^-1 + 1.0 % CaCl₂ (T₅), 500 g N tree^-1 + 1.5 % CaCl₂ (T₆), 625 g N tree^-1 + 0.5 % CaCl₂ (T₇), 625 g N tree^-1 + 1.0 % CaCl₂ (T₈), 625 g N tree^-1 + 1.5 % CaCl₂ (T₉), 500g N tree^-1 + Water spray (T₁₀ control). The source of nitrogen fertilization was neem coated urea. The experimental findings revealed that maximum leaf nitrogen content was estimated under T₉ (3.721% and 3.838% in 2016 and 2017, respectively), while maximum leaf phosphorus content was estimated under T₁ (0.450%) in first and T₃ (0.456%) in second year. During both the years, the maximum leaf potassium content was estimated under T₂ (2.096% and 2.110% in 2016 and 2017, respectively). The highest leaf calcium content was estimated under T₃ (1.735% in 2016 and 1.744% in 2017). Irrespective of nitrogen fertilization levels, highest calcium chloride concentration (1.5%) resulted in phytotoxicity which was evident by marginal leaf scorching. Significant differences for available soil nitrogen were found, while other studied nutrients did not differ significantly.
