Bush Snap Bean as Affected by Different Organic Fetilizers. Benguet State University,
La Trinidad, Benguet.
Adviser: Franklin G. Bawang, MSc.
ABSTRACT
This study was conducted at the Horticulture laboratory field area of Benguet
State University, La Trinidad, Benguet from December 2011 to March 2012; to determine
the effect of various organic fertilizers on the growth and yield of different Bush snap bean
varieties, to determine the best organic fertilizers appropriate for fresh bush snap
bean pods production, and to determine the economics of using different organic fertilizers
on bush snap bean production.
Results showed significant differences between variety and organic fertilizers
with regards to the percentage of plant survival, weight of marketable pods, yield per
plot, computed yield per hectare, average length of pods, occurrence of insect pests (cut
worm), and the number of laterals per plant. As to the number of days to complete
seedling emergence, weight of non-marketable pods, days from planting to harvesting,
occurrence of insect pests (pod borer), plant height, result showed no significant
differences. However, highest return of investment of 27.79 % was obtained by

RESULTS AND DISCUSSION
Soil Analysis
Table 1 shows the soil analysis before and after the study. The soil pH
decreased
slightly from 6.44 to 6.25. On the other hand, the organic matter content decreased from
7.0 to
1.5%, phosphorous, increased from54 to 120 ppm and the potassium increased from
690
to 1,260 ppm. The soil contains high amount of potassium, medium amount of
phosphorous
and it had a sufficient amount of nitrogen.

Growth and Yield Performance of Bush Snap Bean as Affected by Different Organic
Fetilizers | DOQUEZA, MERCY B. APRIL 2012
SUMMARY, CONCLUSIONS AND RECOMMENDATION
Summary
The study was conducted to determine the effect of various organic fertilizers on
the growth and yield of different bush bean varieties, determine the best organic fertilizer
appropriate for fresh pod bean production and determine the economics of using organic
fertilizers in bush bean production under La Trinidad, Benguet condition. The study was
conducted at the Horticulture laboratory area at BSU LaTrinidad, Benguet from December
2011 to March 2012.
Results showed highly significant differences between the two factors: variety and
organic fertilizers. Cv. Contender applied with BSU compost had the highest percentage
of plant survival as compared to the other variety applied with different organic fertilizers
but are statistically comparable to plants applied with siglat fertilizers. For the days from
planting to harvesting, results showed that all varieties had similar days to attain harvesting
stage while plants applied with chicken manure took longer days to form flowers and attain
harvesting stage while bush beans applied with alnus leaves were the earliest to attain
flowering and harvesting stage but are comparable to the rest of the treatments used.
Cultivar Contender applied with BSU compost produced the longest pods at
harvesting stage but are statistically the same with the other treatments while Cv. sablan
applied with chicken manure had the shortest pods at harvesting stage. As to the average
number of lateral branches at harvesting stage, result showed significant differences
wherein Cv. Contender of bush beans applied with chicken manure had the most number
of lateral branches produced. Base on the results, Cv. Contender applied with BSU compost
had longer days to complete seedling emergence, and those applied with alnus compost

showed mild resistance to insect pest particularly cutworm, while Cv. Sablan applied with
chicken dung had the more number of plants affected but in all indications, all the plants
are mild resistant to cutworm while in pod borer results showed in table 10 b. no significant
differences. As noted between the two factors: varieties and kinds of organic fertilizers
used in the study showed that all plants exhibited mild resistant to pod borer. Cv. Bokod
applied with siglat fertilizers produced tallest plant at first harvesting of pods compared to
the other treatments.
With regards to the weight of marketable pods, Cv. Bokod applied with BSU and
alnus compost had a significantly higher weight of marketable pods as compared to other
varieties applied with different organic fertilizers. As to the non-marketable pods, Cv.
Bokod and Cv. Contender varieties applied with chicken manure, sigalt and BSU compost
had a higher weight of non-marketable pods as compared to the rest of the varieties
evaluated. For the total yield per plot and total computed yield per hectare, highly
significant results were observed in bokod variety applied with BSU and alnus compost
fertilizers out yielding the rest of the varieties evaluated. Based on findings of the study,
the application of siglat fertilizers to Cv. Bokod gave the highest return of investment of
33.88%.
Conclusions
Based on the results presented and discussed, all the bush bean varieties applied
with the different organic fertilizers were adapted under La Trinidad, Benguet condition.
Cultivar Contender applied with BSU compost had the highest percentage of plant survival.
Cultivar Bokod applied with BSU compost and siglat fertilizers had the highest weight of
marketable pods while cultivar Sablan applied with NBEM fertilizers had the least weight

of non-marketable pods. Cultivar . Contender applied with alnus compost and BSU
compost were the earliest to attain the harvesting stage. Cv. Bokod applied with BSU and
alnus compost produced the highest yield per plot and also had the highest computed yield
per hectare (tons). Cv. Contender applied with BSU compost produced the longest pods
harvested. It was also observed that Cv. Bokod applied with chicken dung was not resistant
to cut worm insects. Cv. Bokod applied with chicken manure + T-14 produced the tallest
plants. Cv. Contender applied with BSU compost had the highest number of lateral
branches. Better growth and yield of bush beans could be obtained with the application of
siglat fertilizers in the soil having a pH of 6.44 to 6.25, 7.0 to 1.5% organic matter, 54
to120 ppm phosphorus, and 690 to 1,260 ppm of potassium.
Recommendation
Based on the findings of this study, it is therefore recommended all the three (3)
variety applyied with BSU compost or alnus fertilizer are the best suited under La Trindad,
Benguet condition for good performance, yield and marketability of bush bean . It was
futher found that Cv. sablan and Cv. Bokod beans are appropriate for fresh pod bean
production while the Cv. Contender is good for seeds production.
