Nutrient Demand of Oil Palm Hybrids in Tropical America

Nowadays there are several oil palm regions in Latin America with plantings of the OxG material, which is a cross of Elaeis oleifera (American oil palm) with E. guineensis (African oil palm). There are no studies in the agronomy or nutrition of the OxG hybrid. This study tries to evaluate the minimum nutritional requirements for two OxG crosses in Colombia.

IPNI-2010-COL-16

Colombia-16 Rationale. Driven by increased oil demand around the world, the oil palm is now one of the crops with the largest increase in planting area. The common planting materials are progenies of the African oil palm (Elaeis guineensis). Unfortunately in tropical America these E. guineensis related materials are susceptible to a range of diseases, many of them of large economical importance. Recently, the cross between E. guineensis and E. Read more

Interpretive Summary

The results of the nursery phase of the study were validated in commercial plantings of the Astorga, La Cabaña and Unipalma plantations, where field plantings for the second phase of the study are also located. We have confirmed that root production of the OxG hybrid is more prolific and dense, which results in better efficiency in the use of nutrients. The recommendation after three years of studies is therefore to use: 20 to 30 g N; 10 g P; 15 g K, and 0.

The aim in the second phase of this study is to estimate the effect of five application rates of N, P, K, and B in the growth and yield of two crosses of Elaeis oleifera with Elaeis guineensis ("OxG" hybrids) by using a factorial experiment arranged in a central composite design. The study was replicated at three locations—the Casanare, Meta and Tumaco Departments of Colombia—with all of them being important oil palm areas and having the presence of bud rot disease.

Nutrient Demand of Oil Palm Hybrids in Tropical America, 2012 The second phase of this study was initiated at three locations including Astorga (Tumaco Department), Hacienda La Cabaña (Casanare), and Unipalma de los LLanos (Meta) plantations. The soils at these locations were acidic (pH from 4. 3 to 4. 8) with very low P (3 to 5 ppm) and variable percent exchangeable Al (30 to 70%). In each location, two OxG planting materials were evaluated: “m1” from La Cabaña and “m2” from Unipalma.

Nutrient Demand of Oil Palm Hybrids for Tropical America, 2011 This study examines the nutrient demands of the OxG hybrid oil palm and the most adequate tools to calibrate crop fertilization (e. g. foliar critical levels for different nutrients). The nursery phase was initiated in 2010 with two sets of plantlets growing in two locations of Colombia. In each location two parallel studies were carried out with rates of: 1) N, P, and K; and 2) Mg, Ca, and B.
