ABSTRACT

The response of alstroemeria to different kinds and rates of slow release fertilizer
was evaluated under greenhouse condition to determine the growth, flowering, and yield
of alstroemeria as affected by slow release fertilizer application, to determine the effect of
different kinds and rates of slow release fertilizer on the growth and flowering of
alstroemeria, and to determine the economics of using the different slow release fertilizer
treatments in alstroemeria cutflower production. This study was conducted at Ornamental
Horticulture Research Area, Department of Horticulture, College of Agriculture, Benguet
State University, La Trinidad Benguet from September 2012 to January 2013.
Result showed that the two varieties of alstroemeria performed similarly in terms
of the number of flowers produced per plant, number of days from planting to flower bud
formation, number of days from planting to 100% anthesis, and number of days from
planting to 50% anthesis. However the varieties performed differently in terms of the
number of cutflower stems produced per plant. The Cv. Nadya performed better than
shakira and had higher number of laterals per plant at flowering, had taller plants measured
at flowering, and highest number of cutflower stems per plant.

Plants applied with 15g/m2 Osmocote (14-14-14) promoted higher number of
laterals per plant produced, taller plants with higher number of cutflower stems per plant
at flowering than the other treatments that led to higher ROI.

RESULTS AND DISCUSSION
Final Height at Flowering (cm)
Effect of variety There were highly significant differences on the effect of the two
alsroemeria varieties on the final height at flowering. Plants of Cv. nadya were taller at
flowering with the mean of 75.55 cm while plants of Cv. Shaker were shorter with plants
measured at 63.89 cm.
Effect of rate of fertilizer application. There were significant differences on the final
height at flowering as affected by the different rates of slow release fertilizers applied.
Among the treated plants however, those applied with 15g/m2 of Osmocote (14-14-14)
fertilizer were the tallest measuring 79.06 cm at flowering. This was followed by those
applied with 10g/m2 with the mean of 71.55 cm and those applied with 5g/m2 with a mean
of 65.39 cm. The untreated plants were the shortest which measured only 62.39 cm at
flowering.
Interaction effect. The combined effects of the two varieties and the different rates
of fertilizer application had significantly affected the final height at flowering. Results
show that plants of Cv. Nadya treated with15g/m2 were noted to be the tallest at flowering.
Plants of Cv. Shakira were significantly shorter plants indicating that the fertilizers applied
did not significantly enhance the growth of the alstroemeria variety.

Number of Laterals Produced Per Plant at Flowering
Effect of variety. Highly significant differences were noted on the final number of
laterals per plant at flowering of the two alstroemeria varieties (Table 2).Cv. Nadya
produced the higher final number of laterals per plant at flowering with a mean of 17.69,
while Cv.Shakira had fewer laterals with a mean of 13.69 per plant at flowering.
Effect of rate of fertilizer application. Table 2 shows significant differences were
found on the number of laterals as affected by rate of fertilizer application. Plants treated
with 15g/m2 of Osmocote (14-14-14) produced more laterals per plant at flowering with a
mean of 20.11 followed by those applied into 5g/m2 which had a mean of 16.05 and those
applied with 10g/m2 with a mean of 14.83 laterals. The untreated plants produced the
lowest number of laterals per plant at flowering with only 11.76 laterals.

Interaction effect. There were no significant interaction effects between the two
alstroemeria varieties and the different rates of slow release fertilizer application on the
final number of laterals per plant at flowering in alstroemeria.
Number of Flowers Produced Per Plant

Effect of variety. There were no significant differences observed on the number of
flowers produced per plant as affected by the alstroemeria variety. Flower development in

Effect of rate of fertilizer application. Highly significant differences were however
obtained on the number of flowers produced per plant at flowering as affected by the
different rates of slow release fertilizer application. Results show that there were more
flowers produced in plants applied with the higher rate 15g/m2 a mean of 6.00 flowers per
plant. This was followed by the untreated plants which measured with a mean of 4.89
flowers. Those applied with 10g/m2 had the lower flower counting of 4.83, while plants
applied with 5g/m2 had the least number of flowers with only 4.55 flowers per plant.
Interaction effect. There were no significant interaction effects of the two varieties
and the different rates of fertilizer application on the number of flowers produced per plant
at flowering (Table3).

Meteorological data
The air temperature during the study period ranged from13.1 to23.7oc while relative
humidity ranged from 83 to 98%. Temperature and relative humidity during the conduct of
the study were observed to be not suitable for alstroemeria production.
A very little rainfall of 21 mm was recorded from September 2012 to January 2013.
The sunshine duration in the month of September to January was low at 253.3 to 360
minutes per day that has significantly delayed the flowering of alstroemeria plants.

SUMMARY, CONCLUSION, AND RECOMMENDATION
Summary
This study was conducted at the Ornamental Horticulture Research Project Area of
the Benguet State University La Trinidad Benguet from September 2012 to January 2013
to evaluate the growth flowering yield of alstroemeria as affected by slow release fertilizer
application, to determine the effect of different kinds and rates of slow release fertilizer on
the growth and flowering of alstroemeria, and to determine the economics of using slow
release fertilizer treatments in alstroemeria cutflower production.
Results show that there were no significant interaction effects between the varieties
and rates of fertilizer application on the number of days from planting to 100% anthesis,
number of days from planting to 50% anthesis, number of flowers produced per plant,
number of days from planting to flower bud formation, final number of laterals per plant
at flowering and number of cutflower stems per plant in alstroemeria. However, Cv. Nadya
had higher differences were counted number of laterals per plant at flowering, had the
longest cutflower stems at flowering and significantly produced more number of cut flower
stems per plant. On the other hand, on the effect of the different rates of fertilizer
application. Application of 15g/m2 promoted the production of significantly higher number
of flowers and the number of cutflower stems per plant. It has likewise; Significantly
affected the number of laterals per plant at flowering and the final height at flowering.

Conclusion
Based from the results obtained, it is therefore concluded, that the use of osmocote
(14-14-14) in alstroemeria cutflowers production applied at the rate of 15g/m2 led to the
production of desirable growth and quality of alstroemeria plant.
Recommendation
Based from the above findings, it is recommended that slow release fertilizer at the
rate of 15g/m2 osmocote should be applied to improve the vegetative growth and
development and increase cutflower stem of the two varieties grown.
