Pa­paya prop­a­gated by mar­cot­ting

Agriculture - - Contents - BY JULIO P. YAP, JR.

PA­PAYA is a trop­i­cal tree which is com­monly known for its long, lobbed leaves, and large fruits which are filled with tiny black seeds. A pa­paya plant thrives well in hot weather con­di­tions and grows in any part of trop­i­cal coun­tries like the Philip­pines, and of­ten prop­a­gated by seeds.

How­ever, sow­ing the black seeds of the pa­paya fruit is not a guar­an­tee for the farm­ers to at­tain a good yield, pri­mar­ily be­cause some of the seeds may turn out to be­come a male pa­paya tree which will not bear fruits, thus, wast­ing the time and ef­fort of the poor farmer.

To ad­dress this bad­ger­ing con­cern which greatly af­fects the farm­ers, par­tic­u­larly the marginal­ized farm­ers liv­ing in the coun­try­side, the Cen­tral Philip­pines State Univer­sity (CPSU) in Ka­bankalan City, Ne­gros Oc­ci­den­tal, un­der the lead­er­ship of its newly-elected pres­i­dent, Dr. Aladino C. Mo­raca, Ph.D, de­vel­oped and in­tro­duced the “Process of Pa­paya Asex­ual Prop­a­ga­tion Through Mar­cot­ting.”

Ac­cord­ing to Mo­raca, this util­ity model gen­er­ally re­lates to prop­a­gat­ing pa­paya through mar­cot­ting.

It can be noted that a util­ity model is an ex­clu­sive right granted for the par­tic­u­lar in­ven­tion, which al­lows the right holder to pre­vent oth­ers from com­mer­cially us­ing the pro­tected in­ven­tion, with­out his or her autho­riza­tion.

Mar­cot­ting, which is a type of veg­e­ta­tive plant prop­a­ga­tion, is com­monly known as air lay­er­ing that in­volves root­ing of a part of the stem while it is still at­tached to the par­ent plant.

Un­der the ad­vo­cacy of Mo­raca, the suc­cess­ful process of mar­cot­ting the pa­paya tree was made pos­si­ble through the com­bined ef­forts of a team of ex­perts from the CPSU which is com­posed of As­so­ciate Pro­fes­sor 3 and CPSU Moises Padilla Cam­pus Di­rec­tor Ray­mond C. An­to­nio; As­so­ciate Pro­fes­sor 4 and CPSU Qual­ity As­sur­ance Di­rec­tor Mi­la­gros M. An­to­nio; As­so­ciate Pro­fes­sor 5 and CPSU Vice Pres­i­dent for Aca­demic Af­fairs Dr. Fer­nando D. Abello; and, As­so­ciate Pro­fes­sor 3 and Dean of the CPSU Col­lege of Agri­cul­ture D. Sal­vador C. Cas­tor, Jr.

In mar­cot­ting, the in­duc­tion of root de­vel­op­ment is usu­ally done

by slit­ting the part of a plant to be rooted.

Mo­raca says that this tech­nol­ogy is very prac­ti­cal and can be very ap­pro­pri­ate for the pro­duc­tion of pa­paya, which is called the “CPSU Pink Va­ri­ety.”

“There is a need to in­tro­duce a new process of prop­a­gat­ing pa­paya asex­u­ally uti­liz­ing the mar­cot­ting in or­der to pro­duce pa­paya that will guar­an­tee the farm­ers to have a bet­ter yield,” Mo­raca pointed out.

The pri­mary ob­jec­tive of the util­ity model is to pro­vide a process of pa­paya asex­ual prop­a­ga­tion where the grafted pa­paya tree will have a su­pe­rior fruit­ing per­for­mance.

The util­ity model aims to pro­vide a process of pa­paya asex­ual prop­a­ga­tion us­ing the mar­cot­ting method in or­der for the plant to grow faster and pro­duce fruits ear­lier than the con­ven­tional prac­tice of cul­ti­vat­ing pa­paya through the use of seeds.

Mo­raca says this will greatly help the small farm­ers to save their mod­est but hard-earned re­sources in terms of in­vest­ments on ac­quir­ing ex­pen­sive seeds, thus, en­cour­ag­ing the marginal­ized farm­ers to en­gage in the pro­duc­tion of pa­paya by us­ing the mar­cot­ting process de­vel­oped by the CPSU.

Aside from di­rectly ben­e­fit­ting the farm­ers, this util­ity model can also be uti­lized by those liv­ing in the ur­ban­ized ar­eas where the space to prop­a­gate a plant is a peren­nial prob­lem be­cause a mar­cot­ted pa­paya tree can be grown in small con­tain­ers

Mar­cot­ted pa­paya grows faster and pro­duces fruits ear­lier than those grown from seeds.

The rec­om­mended root­ing medium for pa­paya mar­cot­ting is a mix­ture of slightly moist­ened ver­mi­com­post (30 per­cent) and de­com­posed saw­dust or coco­dust (70 per­cent).
