COPAS, FRED D. APRIL 2013. Variety Evaluation of Carrot (Daucus carota L.)
Under Nabalicong, Natubleng, Buguias, Benguet Condition. Benguet State University, La
Trinidad, Benguet.

Adviser: Percival B. Alipit, Ph.D.


ABSTRACT
Seven carrot cultivars were evaluated as to their growth and yield performance to
determine the best variety for Nabalicong, Natubleng, Buguias, Benguet condition.

Results showed that Sigma and Golden State had the longest leaves. However,
Golden State, Kuroda Improved, and Mushashino were harvested earlier at 105 days.
Among the varieties evaluated, Mushashino significantly produced the longest root while
Mushashino and Teracota had the widest roots. Kuroda Improved, Sigma, Golden State
had the heaviest big roots while Golden State had the heaviest medium roots. Golden State,
New Kuroda Guson, Kuroda Improved, Sigma had the least number of forked roots, while
Kuroda Improved, New Kuroda Guson, Sigma, Golden State, Mushashino had the least
number of cracked roots.

Golden State, Sigma, Mushashino, Kuroda Improved significantly had the highest
marketable yield at 100.00, 94.50, 94.00, 90.00, t/ha, respectively. Moreover, the highest
return on investment was obtained from Golden State at 136.54%, followed by Kuroda
Improved at 115.16%, and Mushashino at 110.27%.

RESULTS AND DISCUSSION

Leaf Length at Harvest


Sigma and Golden State variety significantly had the longest leaves while New
Kuroda Guson had the shortest leaves. (Table 1).

There were no significant differences observed on the number of days to harvest.
However, Kuroda Improved and Mushashino were harvested earlier at 105 days as shown
in Table 1.

SUMMARY, CONCLUSION AND RECOMMENDATION

Summary

There were seven cultivars evaluated at Nabalicong, Natubleng, Buguias, Benguet. The
study was conducted to determine the growth and yield performance of the various carrot
varieties and to ascertain the best adaptable carrot variety/ties under Nabalicong,
Natubleng, Buguias, Benguet condition.

Results showed that Sigma and Golden State had the longest leaves. However,
Golden State, Kuroda Improved, and Mushashino were harvested earlier at 105 days.
Among the varieties evaluated, Mushashino significantly produced longest root while
Mushashino and Teracota had the widest roots. Kuroda Improved, Sigma and Golden State
had the heaviest big roots while Golden State had the heaviest medium roots.

There were no significant differences among the varieties in the total number of
roots, weight of small roots, total root weight and average root weight.
.
Golden State, New Kuroda Guson, Kuroda Improved, Sigma, had the least number
of forked roots, while Kuroda Improved, New Kuroda Guson, Sigma, Golden State,
Mushashino had the least number of cracked roots.

Golden State, Sigma, Mushashino, Kuroda Improved significantly had the highest
marketable yield at 100.00, 94.50, 94.00, 90.00, t/ha, respectively. Moreover, the highest
return on investment was obtained from Golden State at 136.54%, followed by Kuroda
Improved at 115.16%, and Mushashino at 110.27%.

Conclusion

Based on the result of the study, Kuroda Improved, Golden State, and Mushashino
perfomed best in yield at Nabalicong, Natubleng, Buguias, Benguet from which return of
investment was derived.

Recommendation


Carrot varieties Kuroda Improved, Golden State, and Mushashino are therefore
recommended to Nabalicong, Natubleng, Buguias, Benguet. However, variety trials should
continuously be undertaken.
