Cabbage (Brassica pekinensis) under Paoay, Atok, Benguet Condition, Benguet State

ABSTRACT
This study on the performance of Chinese cabbage varieties, namely: Green Cool,
Taibyo Nozomi, Vigor 60, Yellow Queen, CR-Chesney and CR- Alabama was conducted
under Paoay, Atok, Benguet Condition to evaluate the yield performance and to determine
the economics of growing these varieties.
Results revealed that CR-Alabama out yielded the other varieties in terms of
percentage heading, average head weight, marketable yield per plot and it had very
compact head formation compared to the other cultivars and it was resistant to insect pest
under Paoay, Atok, Benguet condition.

RESULTS AND DISCUSSION
Days to Heading
The varieties, CR-Alabama, CR-Chesney and Green Cool were significantly the
earliest to form head, while Taibyo Nozomi formed head at the latest, but it is not
significantly different from the check cultivar Green Cool.
This is consistent with the statement of work and Carew (1955) that varietal trial is
important to observe earlier and maturity of different varieties.

Equatorial Diameter of Head
Widest equatorial diameter of heads was measured from CR-Alabama which is
significantly different from other cultivars, while CR-Chesney had the least equatorial
diameter among the test cultivars.
These observations agree with the statement of Work and Carew (1955) that
different varieties have wide range of difference in plant size.

In terms of length Green Cool produced significantly longer heads compared to
the rest of cultivars planted, while Yellow Queen had the least polar diameter of head
among the test cultivars.
These observations agree with the statement of Work and Carew (1955) that

Average Weight of Heads
In terms of average head weight the heaviest was harvested from CR-Alabama that
significantly out yielded the rest cultivars, while CR- Chesney had the lowest average head
weight.
Variety trial is a very important study in order to obtain the best variety adapted to a certain

Head Weight as to Compactness
Among the varieties tested, Green Cool, Vigor 60, CR-Alabama and CR-Chesney
significantly had lower weight of no heads that did not form. There were no significant
differences observed from test cultivars on the weight of loose and slightly compact heads.
Green Cool, Vigor 60, CR-Chesney and CR-Alabama have significantly higher weight of
compact head formation among the test cultivar. Very compact heads were significantly
greater in CR-Alabama among the tested cultivars.

Weight of Heads Infested with Diamond Back Moth
Taibyo Nozomi had the highest insect pest incidence but it is not significantly
different with Yellow Queen varieties. Green Cool, CR-Chesney, CR-Alabama was
observed to be tolerant to diamond back moth.
As explained by Wallace (1969), each variety is different but small sample of the
total number of genes existing for the vegetable crop. Unimproved varieties usually carry
an unselected and essentially random sample of genes, while improved varieties passes
highly selected genes that established high potential for yield pest resistance and other
characteristics which are so essential to profitable vegetable production. It might be that
those cultivars observed to be resistant have more genes resistant have more genes resistant
to diamond back moth compared to those that were rated susceptible.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted to evaluate the yield performance of six (6) Chinese
cabbage varieties under Paoay, Atok, Benguet condition from October to January 2013.
Results shows that cultivar CR-Alabama significantly had, the highest percentage
of heading, and the widest equatorial diameter, while cultivar Taibyo Nozomi and Yellow
Queen had the longest shelf life.
High average weight, marketable weight, total weight, and computed plant per yield
at 97.95 t/ha was significantly obtained in cultivar CR-Alabama. Moreover, this said
variety had very compact heads and it is resistant to insect pest diamond back moth.
Conclusion
Based on the results of the study, it is therefore concluded that among the varieties
tested, cultivar CR-Alabama planted under Paoay, Atok, Benguet condition had the highest
average weight of heads, highest percentage of heading, highest head weight as to
compactness, highest marketable yield per plot and highest ROI.
Recommendation
In terms of having high yield, resistant to insect pest and large heads, Chinese
cabbage ‘CR-Alabama’ is recommended to be grown under Paoay. Atok, Benguet
condition.

ABSTRACT
This study on the performance of Chinese cabbage varieties, namely: Green Cool,
Taibyo Nozomi, Vigor 60, Yellow Queen, CR-Chesney and CR- Alabama was conducted
under Paoay, Atok, Benguet Condition to evaluate the yield performance and to determine
the economics of growing these varieties.
Results revealed that CR-Alabama out yielded the other varieties in terms of
percentage heading, average head weight, marketable yield per plot and it had very
compact head formation compared to the other cultivars and it was resistant to insect pest
under Paoay, Atok, Benguet condition.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted to evaluate the yield performance of six (6) Chinese
cabbage varieties under Paoay, Atok, Benguet condition from October to January 2013.
Results shows that cultivar CR-Alabama significantly had, the highest percentage
of heading, and the widest equatorial diameter, while cultivar Taibyo Nozomi and Yellow
Queen had the longest shelf life.
High average weight, marketable weight, total weight, and computed plant per yield
at 97.95 t/ha was significantly obtained in cultivar CR-Alabama. Moreover, this said
variety had very compact heads and it is resistant to insect pest diamond back moth.
Conclusion
Based on the results of the study, it is therefore concluded that among the varieties
tested, cultivar CR-Alabama planted under Paoay, Atok, Benguet condition had the highest
average weight of heads, highest percentage of heading, highest head weight as to
compactness, highest marketable yield per plot and highest ROI.
Recommendation
In terms of having high yield, resistant to insect pest and large heads, Chinese
cabbage ‘CR-Alabama’ is recommended to be grown under Paoay. Atok, Benguet
condition.
