Effect of Biopotting Quality on Growth and Morphological Quality of Jackfruit Artocarpus heterophyllus Lamk. Seedlings

Abstract

Biopotting was a pot of growing medium for plant seedlings that was environmentally friendly. This study analyzed the effect of biopotting quality made from clay, fruit waste compost of rambutan, jackfruit, durian, market compost and tapioca flour on the growth and morphological quality of jackfruit seedlings. The results of the chemical analysis of biopotting samples containing organic C ranged from 42- 44%, total N ranged from 0.21-0.35%, total P ranged from 28.14-38.25 mgkg-1, potassium (K) ranged from 0.90-1.13me/100g and pH ranged from 4.08-6.68. Physical analysis of biopotting obtained water content ranged from 2.04-3.09%, density ranged from 0.42-0.50gcm-3, water absorption ranged from 200-242% and the level of damage to all biopotting was ≤ 2% so it was included in the undamaged category. Measurement of growth and morphological quality of jackfruit seedlings aged 60 days obtained an average height ranged from 17.85-27.6cm, an average of stem diameter ranged from 0.43-0.47cm, number of leaves ranged from 3-4 strands, root length ranged from 12.5-16.8cm and morphological quality index ranged from 0.092- 0.099. This study concluded that the best quality on M4 biopotting had a significant effect on the growth and morphological quality of the jackfruit Artocarpus heterophyllus Lamk. seedlings
