ABSTRACT
The aim of this experiment
was to get information regarding the amount of fertilizer and irrigation
necessary for maximum production of bushy peppers. The experiment was conducted in the green house of Cimanggu
Research Institute for Spice and Medicinal Crops, Bogor, from October 1999 to
September 2000. The experiment was
arranged in a factorial randomized block design with three replications and six
plants per unit. There were two factors
treated : five levels of watering (7 mm/2 days/plant, 14 mm/2 days/plant, 21
mm/2 days/plant, 14 mm/4 days/plant and 21 mm/4 days/plant) and four levels of
NPKMg 12-12-17-2 (0 g/plant/year,100 g/plant/year, 200 g/plant/year and 300
g/plant/year).
The result showed
the inflorescence and production of bushy pepper were affected by interaction
between watering and fertilization.
Stress condition that effected by unbalanced watering and fertilization
on inflorescence stage adapted by reduced flowers bunch number, abbreviated of
inflorescence process, prolonged period of inflorescence, and abbreviated of

INTRODUCTION
Peppers have been cultivated extensively in the forest garden in
Indonesia. Farmer cultivated them as
climbing plant with supporting poles, so production cost become expensive. In
addition, they cultivated peppers without any fertilizer nor irrigation therefore
they produced low yield.
Bushy peppers are alternatifes technology that
expected increasing yield and reducing production costs. This type peppers could be cultivated more
denssely in the field without supporting poles, so opportuned to cultivated as
multiple cropping and intercropping system between other perenial like coconuts
(Syakir and Zaubin, 1994; Syakir, 1996).
In addition, bushy peppers reached the reproductive phase earliar than
climbing peppers. Bushy peppers also
simple in cultivated and harvested.
Because cuttings derived from flowering shoots bushy peppers have highly
photosynthesis (Helmi, 1999). Their
root system are shallow and less leafy.
About 80% of them spreated until 40 cm depth, therefore water have been
limited component on bushy peppers cultivating (Pujiharti, Dwiwarni and
Muchlas, 1995). These make the root
cannot balance energetic shoot growth.
The condition also caused nutrient deficiency, therefore bushy pepper
needs intensive fertilizing for optimum growth.
Some research
about bushy peppers have been done.
However there are very few studies about the cultivatinon method of
bushy peppers in fields. The aim of this experiment was to get information
regarding the amount of fertilizer and irrigation necessary for maximum
production of bushy peppers.
MATERIALS AND
METHODS
The experiment
was conducted in green house of Cimanggu Research Institute for Spice and
Medicinal Crops, Bogor, from October 1999 to September 2000. Materials that used in this experiment were
bushy peppers variety Petaling 1
(planted on June 1996), NPKMg 12-12-17-2 (ingredients Urea, SP 36, KCl and
Kieserit) and water. Bushy peppers planted in pots (diameter = 37 cm, high = 50
cm) that filled with sandy loam soil (Figure 1).
The experiment was arranged in a factorial
randomized block design with three replications and six plants per unit. There were two factors treated, five levels
of watering and four levels of fertilization.
The first factor consist of 7
mm/2 days/plant (W1), 14 mm/2 days/plant (W2), 21 mm/2 days/plant (W3), 14 mm/4 days/plant (W4) and 21 mm/4
days/plant (W5). The second factor consist of 0 g/plant/year (F0), 100
g/plant/year (F1) 200 g/plant/year (F2) and 300 g/plant/year (F3). Fertilizer divided into four application
with proportion 4:3:2:1. Interval
application was 2 month. Dosage of
fertilizer for each treatment and application dishes laid out on Table 1.

Observed variables were number of flowers bunch, process of
inflorescence, length of flower bunch, number of fruits bunch, length of fruits
bunch, duration of fruits formation, fruits per flowers percentage, dryweight
of 100 grains, and production per plant.
RESULTS AND DISCUSSION
Inflorescence
Number
of flowers bunch. Number of flowers bunch was affected by interaction
between watering and fertilization. The
greatest number of flowers bunch produced by W4F3, whereas fewer number of flowers
bunch dominated by treatment that combined with F0 (Table 2). Watering that combined with F0 and
fertilization that combined with W1 and W4, had prolonged inflorescence. It seen from flowers bunch existence untill
24 weeks since beginning of experiment (Figure 2). According to Mubiyanto (1997) water stress condition would be
increased ABA hormone formation that function as stimulus of flower formation.

Process of inflorescence. Process of inflorescence classified into 4
stage flower development (Figure 3).
All inflorescence stage were affected by interaction watering and fertilization. The faster combination that reached stage 1
was W4F0 and the latest was W1F3. On
stage 2, the faster one was W3F2 and the latest was W4F3, on stage 3, the faster
one was W5F3 and the latest was W1F3, and on stage 4, the faster one was W4F0
and the latest was W3F1. Combination of W1F0, W2F0, W2F1, W3F0, W3F2,
and W4F0 reached every inflorescence stage earlier than another combination,
whereas combination W1F3 and W4F3 delayed (Table 3).
Figure 2. Flowers bunch
number of bushy peppers at various treatment
Different with Iljas (1969) and Helmi (1999)
researches, in this experiment founded phenomenon that male flowers could be
come out before all female flowers appeared, so stage 3 could be occured faster
than stage 2. Beside of difference of
variety and experiment condition, apparently there were another factors that
played a part to determined development process of pepper’s flower on that
stage.

Length of flower bunch.
Length of flower
bunch was affected by interaction between both treatment. Combination of W2F3 and W5F3 produced the
longest flowers bunch or not significantly different with treatment that
produced the longest one on every stage, whereas W1F0, W1F3 and W3F0 produced
shorter flowers bunch (Table 3). Entire
treatment indicated that watering that
combined with F0 and fertilization that combined with W1, inclined to produced
shorter flowers bunch. Soedarsono (1997) reported that water stress would be
reduced size of reproduction organs.

Production
Number of fruits bunch. Interaction between both treatments
significantly influenced to fruits bunch number. The greatest number of fruits bunch produced by combination
of W3F3 (Table 4). Observation seen watering that combined with
F0 inclined to produced fewer fruits bunch.
Increased of fertilizer quantity showed unconsistency response. Beside of competition inter plant organs,
low nitrogen content on medium appeared as limited factor. Sopandie (1997a) reported that the fruits
developed, they required nitrogen very much.
Nitrogen content in this experiment less than 0.2% (Attachment Table 1). According to Landon (1984) this number
included to low category.

Wahid, Djoefrie and Syakir (1999) reported that plant needed more water
on generative phase than vegetative phase and beginner of flower
formation. Scarcing water after flower
developed caused to failured fertilization and formed abnormal flower and
fruit.
Length of fruits bunch. Length of friuts bunch was influenced by
interaction watering and fertilization.
The longest fruits bunch produced by combination of W2F4 and the
shortest produced by W1F3 (Table 5).
Shorter fruits bunch inclined produced by watering that combined with F0
or fertilization that combined with W1 or W4.
According to Mubiyanto (1997) water stress resulted shorther plant organ
on coffea. To produced long fruits
bunch, suitable combination were W2 with F3, W3 with F1, F2 or F3, and W5 with
F2 or F3.

Duration of fruits formation. interaction between both treatments
influenced duration of fruits formation significantly. The faster formation was W1F3, followed by
W4F0, whereas the others treatment not significantly different with W2F0 that
the longest formation (Table 5). There
were inclined faster harvesting produced by treatment that combined with
relatively scarced water. According to
Sopandie (1997b) one of plant adapted mechanism to environtment stress was
accelerate their life cycle.
Fruits per flowers percentage. Friuts per flower percentage influenced by
interaction watering and fertilization.
The lowest percentage produced by combination W4F3, followed by
W3F2 (Table 6). Others combination not significantly

water caused increased of wilting bud percentage on cacao.
Dryweight of 100 grains.
Dryweight of 100 grains just infuenced by watering. The lowest dryweight produced by W4, whereas
the highest one by W2. Although
accepted similar volume with W4, W1 produced dryweight similar with W2 and W5
(Table 7). According to Mubiyanto
(1997) untill certain limited, grains size become bigger and bigger when
climate dried up, more than that, grains size become smaller affected by water
deficit.

Production per plant. Production per plant significantly affected
by interaction watering and fertilization.
The highest production produced by W3F1, however not significantly
different with W5F1. The lowest
production produced by combination of W4F3 (Table 6). Combination of high fertilization and limited watering produced
the lowest production. Reduced production
caused by limited water also reported on coffea (Mubiyanto, 1997), cacao
(Soedarsono, 1997), chasew nut (Lubis Pitono and Wahid, 1999) and pepper (Wahid
et al., 1999).
CONCLUSION
Inflorescence and production of bushy pepper
were affected by interaction between watering and fertilization. Stress condition that effected by unbalanced
watering and fertilization on inflorescence stage adapted by reduced flowers
bunch number, abbreviated of inflorescence process, prolonged period of
inflorescence, and abbreviated of flowers bunch. The condition also caused abbreviated of fruits bunch number,
accelerated of fruits formation, abbreviated of fruits bunch, reduced of fruit
