Description

 As a result of the conducted researches, the labor intensity of pruning apple trees of different rootstock-root combinations, determination of flowering score and fruit set was carried out. The most labor-intensive was the pruning of eight-year-old apple trees of the varieties Askold, Amulet, Renet Simirenko and Reven on medium-sized and semi-dwarf rootstocks when the time was 124-402 and 96-306 man-hours / ha against 31-90 man-hours / ha on dwarfs, and the amount of wood removed was 0.9-5.3 kg / der, which is 3.0-4.1 times more, respectively. The following varieties were noted for high fruit set: Askold on rootstocks D 19-04 (17.2%), M 26 (17.4%), Nadiya (15.8%), M9 (15.2%), Sambirskaya (15 , 6%) KD-5 (19.1%); Amulet on D 19-04 (29.9%), D 471 (20.4%) and K 104 (24.5%), Baturyn (22.1%), Sambir (23.5%) and 54-118 (26.5%), M9 (37.5%); Renet Simirenko on D 11-61 (17%), MM-106 (29.7%), D-471 (16.1%), M 26 (19.5%) and in Revena on MM 106, D-1904 , M-26, 54-118, M26, M9, D10-71, D 30-38, KD-5-40,0-50,4% and slightly less on D 471, D 11-61, K -104, Nadiya, Slobozhanska, KD-4 932-37.7%) and Sambirska, Baturynska and D 11-61 (21.4-26.1%). The most labor-intensive when pruning pears were trees of Yablunivska varieties on rootstocks K-53 (231 sec. / Village), VA-29 (140 seconds / village), KA-92 (215 seconds / village), Striyska on VA -29 (113 sec / der.) K-92 (108 sec / der), and K-53 (98 sec / der), Maria on K 92 (212), VA-29 (80) and K-53 71 sec. / Village), November on IS4-6 (78), K-92 (86) and K-53 (94 seconds / village), which is almost twice as much as on other rootstocks (IS-4- 12, IS-2-10, UUPRO3-6 and seed with Pyrognom insert). High yields of eight-year apple orchards were provided by Amulet varieties on rootstocks D-471 (282.0 c / ha), MM 106 (223.1 c / ha) 54-118 (183.0 c / ha), M 26 (223.0 c / ha), Nadiya (217.0) and on dwarf M 9 (286.0 c / ha), D 30-38 (234.0 c / ha). Askold on rootstocks MM106 (155.2 c / ha), D 11-61 (173.0) Baturynska (207.0) and D 30-38 (160
