Use of Chelating Agents to Modify Cacao Roots for Enhanced Nutrient Absorption in Phosphorus Deprived Media
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 2
Abstract
Nutrient deficiency is one of the prominent causes for limited production in cacao farms in the Philippines. To increase nutrient absorption in fertilizer-starved cacao farms, root modification was studied. Chelating agents were the root modifiers introduced to cacao seedlings. Several 3 and 6-month old cacao seedlings were grown in one of the greenhouses of University of Hawai’ i Manoa at the Magoon. The 98 best grown seedlings from each group were selected for further studies. Samples were transplanted to a media with 50 : 50 mixture of vermiculite and oxisol soils. Chelating agents; glycine (G), oxalic acid (OA), citric acid (CA), trisodium citrate (Na3), 2, 3-dimercapto-1-propanesulfonic acid (DPS) and meso-2, 3-dimercaptosuccinic acid (MDS) were added to groups. The growing seedlings were watered only with a phosphorus deprived Hoagland solution to mimic macronutri- -ent deficiency. Morphological developments were routinely measured. After 10 weeks, the plants were harvested. Micro and macronutrients levels in the leaves were also analyzed. The combined results of morphological and nutrient uptake indicate better development for plants treated with chelating agents such as oxalic acid (OA). Plants treated with DPS, however, performed poorer than the control. Further studies would be needed to evaluate its efficacy especially during the cacao fruit bearing phase, since this study focused only on the developing stage
