Abstract: Fruit and shoot management in peaches (Prunus persica L.) is an important intervention to improve fruit quality and its yield . Studies were conducted through on-farm trials at farmer's fields in Ropar (Punjab) district during 2006-2009 to evaluate the technology of pruning and fruit thinning and its effects on crop yield and fruit quality in six-year-old peach cv. Shan-i-Punjab trees with three treatments viz., T₁=50% pruning of fruitful shoots + cutting of dead and diseased wood in early-January, T₂=T₁+ Fruit thinning during mid-March and T₃=No pruning and no fruit thinning (Farmer Practice-FP). The pruning treatments caused the development of an abundant number of long shoots, which are valuable for fruiting. Mean fruit yield was 50 kg per plant in T₁; 48 kg per plant in T₂ and 32 kg per plant in T₃ (FP). Mean fruit yield was 56.25 % higher in T₁ over T₃ (FP) and by 50.00% higher in T₂ over T₃ (FP). Results revealed that mean fruit weights were 55.10, 70.10 and 41.00 grams in T₁, T₂ and T₃ respectively during 2006-07. Mean fruit weight was 34.39 % higher in T₁ over T₃ (FP) and it was 70.97 % higher in T₂ over T₃ . Similar trend was observed during the following years 2008 & 2009 at all the locations except in 2009 where non-significant reduction in fruit yield was noticed in T₂ over T₃ . The highest benefit cost ratio was obtained in T₂ (3.31) followed by T₁ (3.20) and T₃ (2.32). It was concluded that economic fruit yield can significantly be obtained by imposing 50% pruning of fruited shoots and cutting of dead and diseased wood during early January followed by fruit thinning in mid- March in peaches cv. Shan-i- Punjab in sub mountain zone of Punjab.
