    Effect of central leader training system on growth and productivity of peach (Prunus persica L. Batsch) cv. Shan-i-Punjab at different spacings
    (Punjab Agricultural University, Ludhiana, 2018) Bachittar Singh; Harminder Singh
    The present studies entitled “Effect of central leader training system on growth and productivity of peach (Prunus persica L. Batsch) cv. Shan-i-Punjab at different spacings” was carried out during the years 2017 and 2018 at Fruit Research Farm, Department of Fruit Science, Punjab Agricultural University, Ludhiana. Peach plants of cv. Shan-i- Punjab were planted during January, 2015 at six different spacings i.e. 4.5m x 3.0m, 4.5m x 2.5m, 6.0m x 3.0m, 6.0m x 2.5m, 6.0m x 1.5m and 6.0m x 6.0m. The trees planted at 4.5m x 3.0m, 4.5m x 2.5m, 6.0m x 3.0m, 6.0m x 2.5m spacings were trained to „Central Leader‟ training system, the trees planted at 6.0m x 1.5m were trained to „Y‟-shaped system and those planted at 6.0m x 6.0m spacing were trained to „Modified Leader‟ training system. Vegetative and reproductive growth in terms of tree girth, tree spread, canopy volume, shoot length, chlorophyll content, flower bud density and fruit yield was maximum in 6.0m x 6.0m planted trees followed by trees planted at 6.0m x 3.0m distance. Fruits harvested from 6.0m x 6.0m, 6.0m x 3.0m and 6.0m x 1.5m planted trees were superior in fruit quality (fruit size, weight, grade, colour, TSS and acidity) and matured earlier than other spacings. The radiation interception and penetration in the upper and lower parts of the tree canopy was maximum in 6.0m x 1.5m followed by 6.0m x 6.0m and 6.0m x 3.0m planted trees.
