ABSTRACT

The study aimed to evaluate and compare the growth and yield performance of the
different rice entries and to determine which entry is more adapted and suitable under cool-
elevated areas like La Trinidad, Benguet.
The fourteen entries evaluated were Ketnel (Local check), IR81551-2-1-3-3-2-PR,
PR34126-B-10, NSIC Rc 104, IR82187-17-3-2-1-2, PR34110-B-4-3-1, IR81528- 15- 3-2-2-PR,
PR34131-B-21-1, PR34126- B-2, IR82737-B-B-B-B-182, PSBRC 46, IR83140- B- 11- B,
PR34131-B-20-1 and IR83140-B-28-B.

Results showed that NSIC Rc 104and PSBRc 46 had good growth performance and yield.
These varieties showed significant differences on rate of recovery, tiller number, number of
productive tillers per hill, length of panicle, number of grains per panicle, number of filled grains
per panicle, grain yield per plot, weight of 1000 grains and computed grain yield per hectare.

In addition, all entries need further evaluation for more a stable result under cool,
elevated condition and within other seasons.

INTRODUCTION

Rice Oryza sativa belongs to the Graminae family and is clearly one of the most
important food crops in the world. It feeds almost 40% of the world’s population (De
Datta1981).

In the Philippines, rice is planted in different distinct ecological zones- irrigated,
lowland, rainfed lowland and upland. However, only 1% of rice are grown in the uplands
(Dalrympe, 1986). Most of the upland rice farmers are still growing traditional cultivars
that are low yielding and late maturing. Rice in the uplands is often used for fermentation
or production of wine locally known as “tapuey”, aside from consumption as a staple
food (Tadao, 1994).
Previous studies on rice varietal evaluation observed that rice production in the
highlands is increasing due to higher demand.The growing demand of rice has
encouraged some farmers to go into commercial production of various modern varieties
in the different provinces of the Cordillera region. In fact, modern varieties like IR 3941
had already been introduced in the higher altitudes of the region. With the increasing
demand of modern rice varieties in the world market and a buying price of Php. 35-40 per
kilo, it could be a substantial income for the Cordillera farmers (IRRI, 1986).
Thus, it is essential to develop and discover rice varieties which are suitable to
cool elevated areas.The result of the study could be used as a guide by the farmers for a
better rice yield and profit.

The objectives of the study were to determine the growth and yield of promising
rice entries and to identify the best suited variety under cool-elevated condition.
The experiment was conducted at La Trinidad, Benguet from October 2011 to
January 2012.

REVIEW OF LITERATURE

Importance of Rice to Household and Economy

Rice production and consumption are positively associated with low income and
poverty of the 23 countries in the world that produce more than one million tons of rice.
Almost half have a per capita income of less than 500 dollars. These are countries
categorized by the World Bank as the least developed. Rice is one of the cheapest sources
food energy and their main source of protein. As income increases, people demand
relatively by higher quality food, and resources are shifted from production of rice
production of other food and non farm goods with high income elasticity demand. The
importance of rice to national economy further dwindles as agriculture’s shares in the
national income decline with a faster growth in non farm incomes. Increasing
productivity of rice sector however is an important means of raising the purchasing
capacity of the poor and alleviation of poverty in low income countries (Evensonet al.,
1996).
Rice has always been one of the most important foods in the world. It is estimated
that 40 percent of the world population takes rice as a major sources of food; 1.6 Billion
people in Asia takes rice as their mainstay food. Rice is produced in 111 countries in the
world. The region with high population density and the most rapid population growth
produce and consume the most rice. Furthermore, rice is the staple food for more than
half of the world’s population in Asia alone. Most of the consumers who depend on rice
as their primary food live less developed countries. It is foreseen that the world’s
population may exceed 8 billion by 2025 and will need about 765 million tons of rice, 70
percent than what we consume today (Nanda, 2000).

Problems in Rice Production

The world population would increase by 35 percent from 3.5 billion 1990 to 7
billion by 2015. The population increase ill more than 45 percent in developing countries.
The Unites Nations recent population projected indicates that each year almost 80 million
people are likely to be added to the world’s population during the next quarter century.
Over the period, the absolute population increases will be at highest in Asia, but the
relative increased will be greatest in Africa, where population is expected to almost
double (Evensonet al., 1996).
About 70 percent of the additional production will have to come from irrigated
upland cool elevated areas of Asia and 20 percent from the favorable rain-fed lowland
which was already extensively cultivated. Currently, Asian rice production increase at an
annual rate of only 1.4 percent, which is below the population growth rate. By the year
2025, we need to produce about 60 percent more rice than what we produced today to
meet the growing demand. Further, intensification of their riceland must be pursued
against the backdrop of shrinking land area and decreasing availability and increasing
cost of production input, water, fertilizer, chemical, labor and energy (Balasubramanian,
1999).

Importance of Grain Quality of Rice

It is very difficult to define with precision as preferences for quality vary from
country to country. Few people realize its complexity and various quality components are
involved. The concept of quality varies according to the preparation for which the grains
are to be used. Although some of the desired quality characteristics by grower; millers
and consumers may be the same yet each may place different emphasis on various quality
Growth and Yield of Promising Rice Entries Under Cool,
Elevated Condition /Nemie Rex S. Guerzon. 2012

5
characteristics. For instance, the miller’s basis of quality is dependent upon total recovery
and proportion of the head and broken rice on milling. Consumers based their concept of
quality on the grain appearance, size and shape of the grains, the behavior upon cooking,
the taste, tenderness, and flavor of the cook rice (Singh and Khush, 2000).

Temperature Requirement

Cool temperature, little sunshine condition prevailing in the Cordillera generally
results in low rice yield. Average rice yield in the region is currently placed at 2.1 tons
per hectare. Planting during wet season usually results to sterility of the spikelet (CECAP
and PhilRice, 2000).
Discoloration is the biggest problem of rice during the wet season in cool places
of Cordillera like in Banaue, Ifugao, Philippines. In this case, it can be avoided by late
maturity but it is disadvantageous for double cropping (Tadao, 1993).
Pest Control Management

Integrated Pest Management (IPM) can make a contribution to environmental
sensitive farming. Using GM or conventional crops with resistance to pest are an
important part of IPM. Rotation of modern rice cultivars with different patterns of
resistance is necessary to manage pest damage at the farm.Sanitation and cleanliness
must be observed to help control the infestation of disease. Using a resistant varieties are
said to be the most considered factor in resisting infestation of diseases. (Sheelyet al.,
2000).

Importance of Varietal Evaluation

Varietal evaluation is important to observe performance characters which yield,
earliness, vigor, maturity and quality because varieties has a wide range of differences of
a plant in size and yield performance (Work and Carew, 1995).Furthermore, PRRI (1993)
stated that varietal evaluation is an important in agro-ecology that stabilize the yield at a
higher level that facilitates the production of efficient qualities of seed recommended
varieties and encourage further seed increase for the farmer use.
High yielding and improve cultivars are known to play an important role in
boosting production. Large number of indigenous and exotic accessories of various plants
is evaluated and the number of cultivars are selected and recommended for mass growing
(Bitaga, 2002).
In La Trinidad, Benguet, fifteen rice cultivars were tested. Among these were,
Bassat and Talloythatperformed better and produced the highest grain yield. They had
better adaptability and resistance than other cultivars evaluated under the weather
conditions prevailed on the location where the study was conducted.Varietal trials of
three promising rice selection were also studied in a few locations of Ifugao, Kalinga and
Apayao (Cadatal and Pedro, 1993).

MATERIALS AND METHODS

An area of 403.2 square meters was thoroughly prepared and it was divided into
three blocks. Each block consisted of 14 plots measuring 1.6 m x 6 m corresponding to
the 14 treatments with three replications per block (Figure 1). The treatments were laid
out following the Randomized Complete Block Design (RCBD).
Thirteen (13) promising rice varieties and Ketnel (check variety) were used.
These promising varieties were developed by Philippine Rice Research Institute
(PHILRICE). The recommended fertilizer rate was applied. Hill spacing was 20 cm
between rows with 8 rows per plot and 30 hills per row. Three tillers were transplanted
per hill (Figure 2).

All other cultural management practices necessary to the study such asirrigation,
weeding, pest and disease control were strictly employed.

RESULTS AND DISCUSSION
Agro-meteorological Data

Table 1 shows the temperature, relative humidity, amount of rainfall and sunshine
duration from the October 2011 to January 2012. It was observed that the temperature
ranged from 14.0-22.0°C, relative humidity ranged from 86.00%, and average rainfall is
4.00 mm.
High yielding varieties are tolerant to cool temperatures ranging from 17-220C.
Some modern varieties are sensitive to an average temperature of 150C. Planting modern
rice varieties in the upland need at least 100 mm for a sufficient water supply (IRRI,
2011).
The highest sunshine duration recorded was on the month of October 2011 and
January 2012.

Height of Seedling before Transplanting

No significant differences on the seedling height of the fourteen rice entries were
noted (Table 2). The seedlings were measured from the base to the tip of the longest leaf
using a ruler. It was observed that all entries were almost uniform in height.

Height at Maturity

Plant height at harvest is shown in Table 2. It was gathered that PR34110-B-4-3-1
was significantly taller than other entries, being almost one meter tall followed by
PR34126-B-2 and PR34131-B-21-1 with a mean of 86.07 cm and 84.13cm, respectively.
Ketnel was found the shortest among the entries with a mean of 65. 87 cm, although it is
well-adapted traditional variety. Significant differences may be due to their genetic make-
up. Some varieties with a short final plant height show its resistance to lodging. This will
keep away the panicle from falling on the ground through gravitational pull (Fang, 2005).

Number of Days to Recovery

Table 3 shows the number of days from transplanting to period of recovery which
was recorded when rice plants were almost dark green in color. All the fourteen entries
recovered in ten days except for three entries that recovered two to four days later (Figure
3). Faster recovery enhances the rice plant to reach its vegetative stage earlier.
Consequently, faster recovery may also produce tillers earlier and probably earlier
maturity (IRRI, 2011).
Number of Days from Transplanting
toTillering

The number of days from transplanting to tillering is shown in Table 3. It was
observed that IR81551-2-1-3-3-2-PR, PR34126-B-10, IR82187-17-3-2-1-2, PR34110-B-
4-3-1, IR81528-15-3-2-2-PR, PR34131-B-21-1, PR34126-B-2, IR82737-B-B-B-B-182,
IR83140-B-11-B, PR 34131-B-20-1 and IR 83140-B-28-B significantly produced tillers

earlier within a mean of 20 days as compared to PSBRC 46 within 22 days. Ketnel
produced tillers within a mean of 24 days. Rice varieties that produce tillers in later stage
results to a minimum number of tillers (Lancashire, 1991).

Number of Days from
Transplanting to Booting

The number of days from transplanting to booting is shown in Table 3. It was
observed that NSIC RC 104 was the earliest to boot followed by PSBRc 46, together
withIR82737-B-B-B-B-182 and IR83140-B-11-B that boot two days later. Such a
significant difference is due to varietal characteristics. Earlier booting of rice results to a
thicker and longer neck that keeps away the grains from compactness on their leaf
sheath. Later

check variety, Ketnel was the latest to produce head in 95 days. Earlier heading produces
higher percentage of panicle to emergence while later heading delays ripening of grains
(IRRI, 2011).
Number of Days from
Transplanting to Ripening

Table 4 shows the number of days from transplanting to ripening wherein PSBRC
46 significantly ripened earlier in 112 days. NSIC RC 104 and IR82737-B-B-B-B-182
followed with mean of 114 and 117 days, respectively. Ketnelwasthe latest to ripen (133
days). Timely ripening of rice grains has a greater chance of producing a good quality of
grains (IRRI, 2011)
Tiller Number
The number of tillers at maximum stage was recorded when the flag leaf of the
rice plant came out. Table 5 shows that PSBRC 46 and NSIC RC 104 produced the highest
number of tillers with means of 17.07 and 16.66, respectively. PR34131-B-20-1 and
IR81528-15-3-2-2-PR recorded the lowest number of tillers with means of 11.17 and
11.41, respectively. Tiller number could be a remarkable measure of yield potential in a
certain variety (Fang, 2005). PSBRc 46 and NSIC Rc 104 appear to have greater potential
than the other entries used based on tiller number.
Number of Productive Tillers
Table 5 revealed the number of productive tillers per hill. NSIC RC 104hasthe
most number of productive tillers while Ketnel and IR81551-2-1-3-3-2-PR produced the

least number of productive tillers. Productive tillers exemplify the potential yielding
capability of a certain rice variety. Rice plants with high number of productive tillers
turns out a greater number of grains (IRRI, 2011).

Lodging Resistance

As to reaction to lodging by the fourteen rice entries, it was observed that all
varieties are highly resistant. Fang (2005) stated that resistance to lodging signifies a
greater stand of 90 degrees until plants fully ripen. This will maintain the panicle away
from falling off the ground.

Length of panicle

The length of panicle of the fourteen rice entries is shown in Table 6. Among the
entries evaluated, it was observed that NSIC RC 104 had the longest panicle with a mean
of 19.45 cm. It was followed by PR34131-B-20-1 with a mean of 17.51 cm and Ketnel
had the shortest panicle with a mean of 14.28 cm. Significant differences could be due to
their genetic make-up. Longer panicles contain more grains than shorter ones. Although,
this was proven in almost Asian varieties that length of the panicle is not the basis for
concluding the grain content (Lancashire, 1991).

Spikelet Fertility

Table 6 demonstrates the spikelet fertility of the different entries. It was observed
that NSIC RC 104 was found highly fertile among all entries. IR81551-2-1-3-3-2-2PR,
PR34126-B-10, IR82187-17-3-2-1-2, IR82187-17-3-2-1-2, PR34110-B-4-3-1, IR81528-
15-3-2-2-PR, PR34131-B-21-1,PR34126-B-2, IR82737-B-B-B-B-182, PSBRC 46,
PR34131-B-20-1, IR83140-B-28-B and Ketnel were found fertile. Jagadish (2007) stated
that rice spikelet is more fertile in a temperature rangingfrom 240C-300C.

This is due to the effect on time of the day in spikelet anthesis relative to a high
temperature episode on spikelet fertility.

followed by IR82187-17-3-2-1-2 with a mean of 116.27 while NSIC RC 104 and Ketnel
had the lowest number of grains per panicle with mean of 89.23 and 87.90, respectively.
This result seem to suggest that PSBRc 46 has the greatest number of grains among the
entries tested. Panicle with an optimum number of grains had a greater yield than those of
many compacted grains in a panicle (Fang, 2005).

Number of Filled Grains Per Panicle
The result on filled grains per panicle is shown in Table 7. It was observed that
NSIC RC 104 had the most number of filled grains (62.87) followed by IR83140-B-28-B
(50.80). In contrast, PR34110-B-4-3-1 produced the lowest number of filled grains per
panicle. Most of those varieties that are resistant topests and diseases had a high
percentage of filled grains than unfilled (Fang, 2005).

Grain yield and Computed
Grain Yield per Hectare

Total and computed grain yield of the different rice entries is shown in
Table 8. Statistical analysis shows that NSIC RC 104 produced the highest
computed grain yield over IR81551-2-1-3-3-2-PR and IR 82737-B-B-B-B-182 with a
mean of 2.75 kg per hectare. PR 34126-B-10 and PR34131-B-20-1 obtained the
lowest grain yield per plot with a mean of 1.14 kg. In corresponding to the
computed grain yield per hectare, NSIC Rc 104 gained the highest while PR34126-
B-10 and PR34131-B-20-1

obtained the lowest. Such differences could be attributed to their varietal differences and
compactness of grains in the panicle.

PSBRc 46, PR34131-B-20-1 and IR83140-B-28-B were found susceptible.Rice stem
borers are serious pests of rice. They infest plants from the seedling stage to maturity and
mostly likely during ripening stage but it could be treated by applying lannate and curzate
(IRRI, 2007). Furthermore, NSIC Rc 104 could be used by the farmers for further
evaluation.

Blast (neck rot)

Rice blast disease evaluation was taken before harvest. It was observed that all
entries were resistant to neck rot. The fungus is able to infect and produce lesions on
allorgans of the rice plant except the root (Kato, 1999). In addition, all entries could be
further evaluated by farmers as it was found highly resistant.

SUMMARY, CONCLUSION AND RECOMMENDATION

Summary

PSBRc 46 and NSIC 104 produced the highest number of tillers and productive
tillers. In contrast, Ketnel gained the lowest number of tillers and productive tillers.

NSIC Rc 104 was the earliest to boot and it was found to have highly fertile
spikelet. On the other hand, Ketnel was the latest to boot. NSIC Rc 104 produced the
longest panicle and highest number of filled grains. Consequently, it gained the highest
yield. Ketnel recorded the lowest yield.

PSBRc 46 was the earliest to form head and ripen, while Ketnel was the latest. It
also obtained the highest number of grains per panicle in contrast with Ketnel which
produced the lowest.

Furthermore, PR 3410-B-4-3-1 was the tallest at maturity while Ketnel was found
the shortest. Also, PR34131-B-20-1 had the heaviest weight of 1000 filled grains.
Conclusion
Results showed that NSIC Rc 104, IR81551-2-1-3-3-2-PRand PSBRc 46 had
good growth performance and yield. These varieties showed significant differences on
rate of recovery, tiller number, number of productive tillers per hill, length of panicle,
number of grains per panicle, number of filled grains per panicle, grain yield per plot,
weight of 1000 grains and computed grain yield per hectare.
NSIC RC 104 was the earliest to boot and ripen. Consequently, it produced the
highest yield. Most of the entries were susceptible to white heads and dead hearts that
resulted to a low yield.
