Economic yield of Asian pear(Pyrus pyrifolia L.) growing in subtropical –sub humid region of Ranchi can be achieved by adopting some cultural practices like girdling ,pruning of current season growth up to 50 % and there by application of flowering induction hormone thio-urea (5%)in different treatment combinations. The experiments were conducted during 2006-2007 and 2013-1014 at ICAR-RCER, Research Center, Ranchi, India. In the first experiment the result revealed that increased in yield from 2.07 kg (control) to 20.64 kg in T3 treatment [No Girdling+ Prunning+ thiourea (5%)], which is considered the best treatment on junior adult bearing plant (7-8 yrs). It was evident that either pruning or girdling with application of dormancy breaking chemical thiourea (5 %) resulted in at par yield, which indicated that unproductive pear orchards adjoining to Netrahat hills and Ranchi were required some cultural practices (training, pruning, girdling, application of dormancy breaking chemical, etc.) to become fruit full. After a long gap, during 2013 -2014 one additional treatment of irrigation from bud break to peanut stage was replaced by strapping which enhanced the production /plant remarkably. With regard to fruit quality, in first experiment, T1 treatment [Girdling + Pruning + Thiourea (5 %) ]resulted in having the highest TSS (12.2 0B) and total sugar of 6.8 % possibly due to medium sized fruit and less yield as compared to treatment T3 and T4 [Thio-urea (5%) + Non-pruning and Girdling]. In case of second experiment conducted during 2013-14 irrigation treatment was given followed by 50% pruning and 5% thiourea application. The treatment 1 comprising of 50% pruning and 5% thiourea application during dormancy breaking and 32 lit water/plant/week up to peanut stage from pollination markedly increased in fruit set (73 %) and the yield [77.56 kg /14 yrs plant].
