Abstract:
An experiment was carried out to know the effect of plant spacing and training methods on growth and yield attributes of guava cv. Arka Mridula under high density planting system at Horticultural Research Station, Aswaraopet, Khammam, Telangana, India during the year 2013-2016. Among different plant spacing systems wider plant spacing system (1.5 X 2.0 m) significantly increased the plant spread (1.71 m), number of fruits per plant (42.66) and fruit weight (160.91 g) compared to other spacing systems, whereas maximum yield per unit area was recorded in closer spacing system (1 X1 m) (19.34t/ha). Among training methods, vertical single stem with 3-4 branches has recorded the maximum number of fruits per plant (40.48) and yield per unit area (13.64 t/ha) whereas, tatoora with 2 primary branches training method has recorded maximum fruit weight (147.24 g) compare to other treatments. However, training methods did not significantly influence the vegetative growth parameters viz., plant height, and plant spread. Among interactions plants spaced with 1.5X 2.0 m along with vertical stem training method (3-4 primary branches) heading back done at 1.0 m of plant height recorded maximum number of fruits per plant (45.16) and fruit weight (161.85 g). Maximum yield was recorded in plants spaced with 1.0X 1.0 m along with tatoora training method (2 primary branches) heading back done at 1.0 m of plant height (20.07 t/ac) compare to other interaction treatments.
