| Abstract:
Peach cultivation is gaining popularity in the north Indian subtropics due to higher returns on a unit area basis and availability of suitable low chilling peach cultivars. Information on the use of high density planting of peach in subtropics is inadequate. Trees of Shan-i-Punjab peach were planted at three spacing viz. 6 x 6 m, 3 x 3 m and 6 x 1.5 m accommodating 289, 800, 1111 trees per hectare, respectively. In 3 x 3 m spacing, there were 3 solid rows, separated by a gap of 6 m after every 3 rows. Trees planted at 6 x 6 m and 3 x 3 m were trained to modified leader system and those planted at 6 x 1.5 m were trained to ‘Y’-shaped structure. Maximum tree girth (59.21 cm) of six-year-old trees was recorded in 6 x 6 m planted trees followed by trees planted at 3 x 3 m (48.60 cm) and 6 x 1.5 m (40.38 cm) distances. Trees planted at 6 x 6 m recorded significantly higher fruit yield per tree but productivity was maximum in the 6 x 1.5 m planted trees. The cumulative yield over a five year period was maximum (85.06 tonne/ha) in 6 x 1.5 m planted trees followed by trees planted at 3 x 3 m (56.74 tonne/ha) and 6 x 6 m (51.32 tonne/ha) distances. Fruits harvested from 6 x 6 m and 6 x 1.5 m planted trees were superior in quality and matured earlier than those harvested from the spacing of 3 x 3 m. The percentage of marketable fruit was maximum in 6 x 1.5 m and minimum in the 3 x 3 m planted trees. | |
