Response of Abaca (Musa textilis Née) to shade, irrigation and fertilization

Abaca plants

Abaca (Musa textilis Née), a relative of the edible banana (Musa acuminata and Musa balbisiana), is a native to the Philippines. It is grown primarily for its fibers which are utilized by the pulp, cordage and fiber craft industries. Studies have shown that the specific tensile strength of abaca fiber is comparable to or even higher than that of fiberglass (Bledzki et al., 2007;Sinon, 2008).

Dr. Marlito Bande and co-workers, in a paper to be published in the international journal Industrial Crops and Products 42:70– 77, reported on the optimum light, nutrient and water requirements of abaca to attain optimum yield. They also discussed how these parameters affect fiber recovery and fiber quality under field conditions. 

They showed that abaca planted under 50% shade had significantly (p < 0.01) higher fiber yield than those planted under the other shade/light treatments (30% and 40% of full sunlight using polypropylene shade nets) since the plants pseudostem under such treatment were longer, bigger and heavier.They revealed that the combination of irrigation and fertilization further enhanced fiber yield to as much as 41% but this was not enough to offset the effects of shade on the performance of the plant which significantly (p < 0.01) increased fiber yield to as much as 165%. Shade and irrigation–fertilizer application had no significant effect on fiber fineness and tensile strength. 

They concluded that 50% shade is the optimum requirement of abaca to achieve an optimum machine stripped fiber yield of 135.04± 4.31 g/plant without affecting fiber quality for industrial purposes.

The study which was conducted in Ormoc, Leyte, Philippines was funded by the German Research Foundation (DFG).

I love this post subject. I've recently been experimenting with loosely woven Jute Burlap as a possible material for a plant root container which will for Leguminous plants in the pea family which could be out planted whole and eventually break down in the soil.

I'll post a link in a few weeks on the progress. Do you know how long this finer will take to break down ? Can this plant be grown under Date Palm Trees in dry heat deserts or does it require a lot of humidity ?

Thanks again for this.

I see Fiber is very helpful ^^
