Field experiments in two crops of papaya were conducted at ICAR-Indian Institute of
Horticultural Research for four years during 2016-19 to standardise spacing with optimum
soil volume wetting for drip irrigation. Narrowing the plant rows drastically reduced the
plant height while leaf production affected significantly due to reduction in intra row spacing.
The height at first fruiting was significantly lower with a spacing of 1.8 m x 1.5 m (56.4
cm) significantly differing from both 1.5 m x 1.5 m (60.9 cm) or 1.8 m x 1.8 m (66.8 cm).
Significantly higher mean fruit yield (42.2 t/ha) was recorded with the spacing of 1.5 m x
1.5m as compared to either 1.8m x 1.5m (23.4 t/ha) or 1.8m x 1.8m (22.1 t/ha). Significantly
higher water use efficiency (71.3 kg/ha.mm) was recorded in papaya by following closer
spacing of 1.5 m x 1.5 m. Among the interactions, higher papaya yield (48.0 t/ha) was
recorded with normal drip irrigation (80% soil volume wetting) under closer spacing
(1.5 m. x 1.5 m). Further, higher water use efficiency (129 kg/ha. mm) could be obtained
by scheduling the irrigation at 30% soil volume wetting especially by planting at
1.5 m. x 1.5 m. spacing suggesting its suitability for water scarcity areas.
