ABSTRACT
This thesis was conducted to evaluate the yield performance of the five bush bean
varieties. Specifically, it aimed to determine the growth, yield and profitability of growing
bush snap bean under organic farming system.
The results of the study revealed that ‘Contender’ had the least number of days to
germinate. ‘China 804’ obtained the heaviest marketable pods ‘China 804’ led on the
computed marketable yield per plot with a mean of 6.17 kg/ 5m2 followed by ‘Sablan’
(5.16 kg/ 5 m2), ‘Contender’ (4.73 kg/ 5 m2), ‘Bokod’ (3.87 kg/ 5m2) and the lowest is the
‘French bean’ (3.63 kg/ 5 m2).
As to profitability, ‘French bean’ obtained the highest return on investment (ROI)
of 90.06% or PhP 0.90 for every peso invested in the production followed by ‘China 804’
(71.24%), ‘Sablan’ (43.38%), ‘Contender’ (35.53%) and ‘Bokod bean’ (12.93%).

RESULTS AND DISCUSSION
Number of days from sowing to 50% emergence
With regards to the number of days from sowing to 50% emergence, significant
differences were obtained as shown in Table1. ‘Contender’ was the earliest to attain 50%
emergence having a mean of 7.67 corresponding to 7days compared to the ‘French bean’
which has the longest number of days before attaining the 50% emergence with a mean of
8.67. The other varieties (‘Bokod’, ‘Sablan’, and ‘China 804’) had comparable means of
8.0.

can be attributed to their inherent varietal characteristics.

It has been observed that numerically, ‘French bean’ plant were the most
susceptible to bean rust although showed mild resistance to pod borer. However, statistical

that ‘Contender’ had the lowest non-marketable pods. These differences might be due to
different farm management practices applied on both studies.

Economic Analysis
Under organic farming system ‘French bean’ obtained the highest return on
investment of 90.06% or PhP 0.90 for every peso invested in the production despite that it
is one of the lowest in marketable yield. This can be attributed to the fact that ‘French bean’
has the highest price in the market as compared to the other varieties. This was followed
by ‘Sablan’, ‘China 804’, ‘Contender’ and ‘Bokod’, respectively in that order.

SUMMARY, CONCLUSIONS AND RECOMMENDATIONS
Summary
The study was conducted at Balili Experimental Area Benguet State University La,
Trinidad Benguet from October 2012 until January 2013, to determine the growth, yield
and profitability of selected bush beans grown under the organic production system.
The results of the study revealed that ‘Contender’ has the least number of days to
attain 50% emergence having a mean of 7.67 compared to the ‘ French bean’ which has
the longest number of days with a mean of 8.67. However, there were no differences
observed among the treatments with regards to the number of days from sowing to first
harvest. ‘French bean' is the most resistant variety against pod borer. Bean rust infection
was noted on all of the varieties evaluated. ‘China 804’ produced the highest pod yield
with 5.10kg per plot followed by ‘Contender’, ‘Sablan’ ‘Bokod’ and ‘French beans’ with
4.76, 4.10, and 3.97 kilogram per plot, respectively. ‘China 804’ obtained the heaviest
marketable pods with 3.08 kg mean, compared to ‘French bean’ having the lowest mean of
1.82 kg. ‘China 804’ produced the highest computed marketable yield with a mean of 6.17
kg followed by ‘Sablan’ (5.16 kg), ‘Contender’ (4.73 kg), ‘Bokod’ (3.87 kg) and the lowest
is the ‘French bean’ (3.63 kg).
As to profitability, ‘French bean’ obtained the highest return on investment (ROI)
of 90.06% or PhP 0.90 for every peso invested in production followed by ‘China 804’
(71.24%), ‘Sablan’ (43.38%), ‘Contender’ (35.53%) and ‘Bokod bean’ (12.93%).

Conclusions
Based on the results ‘China 804’ produced the highest yield per plot and the second
highest return on investment, whereas ‘French bean’ gave the highest return on investment
despite of being the lowest in weight, since it has the highest selling price of PhP 120 per
kilo compared to the other varieties that was sold PhP 60 per kilo at the BSU Organic
Market.
Recommendations
It is therefore recommended that ‘French bean’ be used for planting in order
to obtain higher return on investment. It is also recommended that ‘China 804’ be planted
for its heavy weight of marketable pods under organic production system. To verify the
results of this study, planting at other times of the year is recommended to verify the
performance of the five varieties evaluated in this study.

The results of the study revealed that ‘Contender’ had the least number of days to

‘French bean’ (3.63 kg/ 5 m2).
As to profitability, ‘French bean’ obtained the highest return on investment (ROI)

Economic Analysis
Under organic farming system ‘French bean’ obtained the highest return on
investment of 90.06% or PhP 0.90 for every peso invested in the production despite that it
is one of the lowest in marketable yield. This can be attributed to the fact that ‘French bean’
has the highest price in the market as compared to the other varieties. This was followed
by ‘Sablan’, ‘China 804’, ‘Contender’ and ‘Bokod’, respectively in that order.

SUMMARY, CONCLUSIONS AND RECOMMENDATIONS
Summary
The study was conducted at Balili Experimental Area Benguet State University La,
Trinidad Benguet from October 2012 until January 2013, to determine the growth, yield
and profitability of selected bush beans grown under the organic production system.
The results of the study revealed that ‘Contender’ has the least number of days to
attain 50% emergence having a mean of 7.67 compared to the ‘ French bean’ which has
the longest number of days with a mean of 8.67. However, there were no differences
observed among the treatments with regards to the number of days from sowing to first
harvest. ‘French bean' is the most resistant variety against pod borer. Bean rust infection
was noted on all of the varieties evaluated. ‘China 804’ produced the highest pod yield
with 5.10kg per plot followed by ‘Contender’, ‘Sablan’ ‘Bokod’ and ‘French beans’ with
4.76, 4.10, and 3.97 kilogram per plot, respectively. ‘China 804’ obtained the heaviest
marketable pods with 3.08 kg mean, compared to ‘French bean’ having the lowest mean of
1.82 kg. ‘China 804’ produced the highest computed marketable yield with a mean of 6.17
kg followed by ‘Sablan’ (5.16 kg), ‘Contender’ (4.73 kg), ‘Bokod’ (3.87 kg) and the lowest
is the ‘French bean’ (3.63 kg).
As to profitability, ‘French bean’ obtained the highest return on investment (ROI)
of 90.06% or PhP 0.90 for every peso invested in production followed by ‘China 804’
(71.24%), ‘Sablan’ (43.38%), ‘Contender’ (35.53%) and ‘Bokod bean’ (12.93%).

Conclusions
Based on the results ‘China 804’ produced the highest yield per plot and the second
highest return on investment, whereas ‘French bean’ gave the highest return on investment
despite of being the lowest in weight, since it has the highest selling price of PhP 120 per
kilo compared to the other varieties that was sold PhP 60 per kilo at the BSU Organic
Market.
Recommendations
It is therefore recommended that ‘French bean’ be used for planting in order
to obtain higher return on investment. It is also recommended that ‘China 804’ be planted
for its heavy weight of marketable pods under organic production system. To verify the
results of this study, planting at other times of the year is recommended to verify the
performance of the five varieties evaluated in this study.
