Study on different nitrogen regimes through neem coated urea and calcium sprays on physico-chemical attributes and maturity of peach fruits

Author(s): Kamal K Pande and DC Dimri
Abstract: An investigation was conducted at Krishi Vigyan Kendra (ICAR- VPKAS), Kafligair, Bageshwar (Uttarakhand) in randomized block design with three replications and ten treatments during the years 2016 and 2017 in peach cv. Red June. The treatments comprised three levels of nitrogen fertilization (375 g, 500 g, 625 g per tree through neem coated urea) along with three concentrations (0.5%, 1.0% and 1.5 %) of calcium chloride for foliar spray, and a control (500 g N per tree through neem coated urea along with water spray). Thus there were ten treatments viz., 375 g N per tree + 0.5% Ca Cl2 (T1), 375 g N tree-1 + 1.0% Ca Cl2 (T2), 375 g N tree-1 + 1.5% Ca Cl2 (T3), 500 g N tree-1 + 0.5% Ca Cl2 (T4), 500 g N tree-1 + 1.0% Ca Cl2 (T5), 500 g N tree-1 + 1.5% Ca Cl2 (T6), 625 g N tree-1 + 0.5% Ca Cl2 (T7), 625 g N tree-1 + 1.0% Ca Cl2 (T8), 625 g N tree-1 + 1.5% Ca Cl2 (T9), 500g N tree-1 + Water spray (T10 control). The experimental findings revealed that maximum polar diameter of fruits (60.49 mm in 2016 and 61.45 mm in 2017), fruit width (58.68 mm in 2016 and 59.38 mm in 2017), fruit weight (91.41 g in 2016 and 91.71 g in 2017) and fruit volume (96.32 ml and 96.93 ml in first and second year, respectively) of fruits were measured in T5 while the minimum values for these attributes were recorded under T7. In first year the maximum specific gravity of fruits was measured under T2 and in second year under T1, however in both the years it remained statistically at par among T1, T2 and T3. The maximum TSS – Acid ratio (11.82 in 2016 and 11.45 in 2017) and ascorbic acid content (3.747 mg/100 g in 2016 and 3.700 mg/100 g in 2017) were recorded in treatment T2. Treatments T1, T2 and T3 took minimum days (65.33 in 2016 and 66.67 in 2017) from fruit set to give first harvest in both the years of experiment, but statistically these were at par to T4, T5, T6 and T10.
