Closer Spacing and Goat Urine Speed Up Manglid Growth

A research team from the Agroforestry Technology Research and Development Centre has found that planting spacing and the application of goat urine influence the early growth of manglid (Magnolia champaca). Up to 19 months of age, the best treatment was 2 x 2 metre spacing with 240 ml of goat urine per plant. This treatment produced a height of 191.5 cm and a diameter of 3.83 cm. The research is important because manglid is a priority commodity in West Java whose productivity can be improved by managing the growing environment.

The study compared three planting spacings: 3 x 3 metres, 2 x 3 metres and 2 x 2 metres. Three doses of goat urine were also tested: none, 240 ml and 480 ml per plant. Of these spacings and doses, the combination of 2 x 2 metre spacing with 240 ml of goat urine gave the best growth results up to 19 months of age. According to the study, goat urine can be used as a foliar fertiliser to support plant growth.

For forest farmers and forest-edge communities, these results offer a simple guide: adjusting planting spacing and using goat urine can be a way of caring for manglid during its early growth. However, the study only observed growth up to 19 months of age, so the results do not yet describe growth over a longer period.
