MYCORRHIZIC BIOFERTILIZER AND MINERAL FERTILIZER ON Elaeis guineensis Jacq. GROWTH IN NURSERY

Abstract

The influence of Rhizophagus intraradices in interaction with mineral fertilization on the growth of two oil palm hybrids, Deli X Ghana and Deli X Nigeria, was evaluated in Huehuetán, Chiapas. To develop the research, the experiment was established in a random block design with eight treatments and 16 repetitions. The treatments used with both hybrids were: 1) Rhizophagus intraradices, 2) 80N-60P-80K-10Ca-10Mg+B, 3) R. intraradices + 80N-60P-80K-10Ca-10Mg + B, and 4) Regional control 18N-46P-00K and 17N-17P-17K. The study variables were: length of stem, diameter of stem, number of leaves, aerial and root biomass, and foliage health. The data were analyzed statistically by applying the STATGRAPHICS
Centurion XVI package, and the multiple-range Tukey test (P?0.05) was used to compare means. Results indicate that the Deli x Ghana hybrid presents greater plant development in comparison to Deli x Nigeria. The treatment with R. intraradices plus mineral fertilization was better for the growth variables and aerial biomass, and decrease of root biomass, and it presented less damage from pests and disease.
