dc.description.abstractABSTRACT The present investigation entitled “Effect of leaf fruit ratio and girdling on the fruit yield and quality of nectarine (Prunus persica var. nucipersica) cv. Silver King” was carried out in the experimental orchard of Department of Fruit Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni-Solan (H.P.) during the year 2014. Eight years old uniform nectarine plants of cultivar Silver King, raised on wild peach seedling rootstock were selected. The plants were planted at a spacing of 2 m×3 m and trained according to open centre system. The research trial was laid out in Randomized Block Design (RBD) with 10 treatments viz., T1 (leaf fruit ratio 20:1), T2 (leaf fruit ratio 30:1), T3 (leaf fruit ratio 40:1), T4 (leaf fruit ratio 50:1), T5 (girdling half the bark), T6(leaf fruit ratio 20:1 + girdling half the bark), T7(leaf fruit ratio 30:1 + girdling half the bark), T8(leaf fruit ratio 40:1 + girdling half the bark), T9(leaf fruit ratio 50:1 + girdling half the bark) and T 10 (control). The fruit yield decreased linearly with the increase in leaf fruit ratio and lowest yield was recorded with treatment T9 (leaf fruit ratio 50:1 + girdling half the bark). The highest leaf area, chlorophyll content and photosynthetic rate were recorded in T 9(leaf fruit ratio 50:1 + girdling half the bark), leaf nutrients viz., N, P, K, Ca and Mg decreased with increased leaf fruit ratio alone or in combination with girding. However, the fruit quality characteristics viz., fruit size and fruit weight were recorded highest in treatment T 8 (leaf fruit ratio 40:1 + girdling half the bark). While, quality in terms of total soluble solids (TSS), total sugars and sugar acid ratio were recorded highest in treatment T 9followed by the treatment T 8 . On the other hand, the lowest acidity was recorded in T 9 (leaf fruit ratio 50:1 + girdling half the bark) followed by T 8 (leaf fruit ratio 40:1 + girdling half the bark). All the leaf fruit ratio treatments advanced the harvest date by 1 to 4 days compared to control and earliest harvesting was recorded in treatment T9(leaf fruit ratio 50:1 + girdling half the bark) . Thus, leaf fruit ratio 40:1 coupled with girdling half the bark followed by leaf fruit ratio 50:1 coupled with girdling half the bark were found suitable for cv. Silver King under mid hill conditions of Himachal Pradesh (India).en_US
