MANILA, Philippines — A cooperative
leader in San Manuel, Tarlac, has harvested a record 16.2
tons of yellow corn per hectare. The feat was called y experts
as the highest per hectare yield recorded in the country so
Posting the record-breaking harvest was Juanito Rama, head
of the San Manuel Multi-Purpose Cooperative. Earlier, he
volunteered his 2.5 hectare corn field for a demonstration
test of a combination of cutting-edge farming practices,
including zero tillage or no plowing done, and the use of
a liquid organic-based fertilizer called Masinag.
The 2.5-hectare farm of Rama yielded a total of 40,500
kilos worth R506,250. The farmer leader said he used hybrid
seeds supplied by one of the country’s biggest corn breeders
and applied six bags of complete commercial fertilizer plus
six liters of the liquid organic fertilizer for each hectare
of his corn field. He planted the seeds without plowing
The combination of the two bold farming techniques, zero
tillage and the use of liquid fertilizer, cut his labor
cost and input costs by half and increased his net earnings.
A support group of experts, including the Land Bank of
the Philippines, a scientist from the Central Luzon State
University, the Department of Agriculture through the New
National Agribusiness Corp. (Nabcor), the seed supplier
and the developer of the liquid fertilizer contributed to
Dr. Nenita de la Cruz, leader of the team of farm scientists
from CLSU involved in the field test, said that neighbors
of Rama were skeptical when her group guided Rama in using
the zero tillage faming technique.
Direct seeding was done on the Rama demonstration farm
without plowing the field. It was only cleared of the remaining
rice stubbles after the wet cropping season in November
A nearby farm where the prevailing farm practices were
used were used by the scientists as a “control” field and
the basis of their scientific analyses and comparison. The
yield in the control farm was 12 tons per hectare for inputs
of 16 bags of commercial fertilizer.
The newly planted corn was rained out and I feared the
seeds would not germinate, but they did, said Rama in recounting
his experience to representatives of the Federation of Tarlac
Cooperatives on the day of the harvest.
The farming technology on the Monsanto Bt corn seed was
used with some innovations, particularly the use of the
liquid organic fertilizer and zero tillage.
With the success of the field demo test, the package of
technology applying the foliar fertilizer and zero tillage
will soon be taught to the other corn farmers, according
to Dr. de la Cruz.
