Comparative studies on growth, flowering, fruit set and yield of some apple (Malus × domestica Borkh.) cultivars under mid hill conditions of Himachal Pradesh, India

The study was carried out in the experimental orchard of the HRTS & KVK, Kandaghat, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during the year 2015-16. The experiment was laid out in Randomized Block Design with four replications. The observations were recorded on various parameters of tree growth, flowering, fruit set and yield. Among different cultivars Oregon Spur II recorded maximum increment in the trunk girth (8.10 %) and tree height (22.37 %). Tree spread (1.74 m) and tree volume (2.13 m3 ) was highest in Gale Gala while, minimum tree spread (0.35 m) and tree volume (0.35 m3 ) was recorded in cultivars Oregon Spur II and Scarlet Spur II respectively. Date of pink bud, first flowering and full bloom was early in cultivar Gale Gala (18th March, 20th March and 27th March) while, it was late in cultivar Gibson Golden (24th March, 28th March and 1st April). The highest fruit set (93.19 %) was recorded in Golden Delicious and least in Early Red One (44.05 %). Highest yield (9.91 kg/tree) was recorded in Gale Gala and lowest (0.65 kg/tree) in Oregon Spur II. | Comparative studies on growth, flowering, fruit set and yield of some apple (Malus × domestica Borkh.) cultivars under mid hill conditions of Himachal Pradesh, India
