Effect of cultar on growth, yield and fruit quality in grown up gola pear trees

Trunk soil line pour application of cultar (PP 333) @ 0.025–1.2 g a.i. cm⁻¹ trunk diameter (TD) at late fall state in January 1994 and again in 1995 controlled vegetative growth, enhanced productivity and fruit quality in 10–11 year old Gola year (Pyrus pyrifolia (Burm.) Nakai) trees growing in subtropical plains of Uttar Pradesh. Cultar @ 0.3 g a.i. cm⁻¹ TD lowered the growth to half to one third with more than 1.35 times increase in yield and considerable improvement in fruit quality. Fruit quality and yield improved further in higher levels of cultar but only at the expense of severe reduction in growth of the fruiting trees.
