I nt r oduct ion
Sweet pot ato ( I pom oea bat atas L.) is a crop that has great potent ial t o be developed in I ndonesia t o
prevent m alnut rit ion and enhancing food securit y. Sweet pot ato is a plant producing carbohydrates is
ranks as t he world’s seventh m ost im port ant food crop after wheat, rice, m aize, potat o, barley and
cassava and can be used as an alternat ive of wheat flour. I n addit ion, sweet pot at o have prospect s as
a superior agricult ural com m odit y for it s easy m anagem ent, drought resistant and can be grown on a
variet y of alt it ude ranging from lowland to highland and able t o adapt in areas of less fert ile and dry

( Eskin, 1989) . Sweet pot at oes cont ain vit am ins and m inerals, and can be used as forage and indust ry
( t ext iles, adhesives, cosm et ics, pharm aceut icals and food) ( CI P, 1999; Ofori, 2009). The added value
of sweet pot ato can be obt ained by processing fresh sweet pot at o into flour, butt er, chips, noodles,
st icks and feed. Sweet potat o flour can be processed int o dry cakes, ice cream , sweet rolls and juice.
Sweet potat o product ion in I ndonesia in 2013- 2014 decreased from 2,386 int o 2,382 m illion t ons.
Likewise, t he sweet pot ato harvest area decreased from 161.85 t housand ha ( 2013) t o 156.67
t housand ha ( 2015) ( BPS, 2015) . This low product ion caused by m any fact ors, am ong ot hers, for not
using superior clones, unproper cult ivat ion t echniques and cult ivat ion of t he sweet potat o only as a
byproduct . Effort s to increas t he product ion of sweet potat o are being conduct ed, by using superior
clones, by plant ing clones adaptable t o specific environm ents ( Rahayuningsih et al., 2002).
Opportunit ies t o im prove t he product ivit y of sweet potat o is st ill quit e large, with t he availabilit y of
superior clones t hat have t he potent ial t o be released as new variet ies. Chance to add or assem ble
new variet ies are quite large with t he int roduct ion of foreign variet ies. Developm ent variet ies of sweet
potat o clones are aim ed at im proving yield pot ent ial, short lifespan ( early m at uring) , resistant t o pests
of Cylas, and a high t olerance for intercropping (Balai Penelit ian Tanam an Pangan, 2009).
Besides t he clones, product ivit y is also determ ined by organic m att er. Organic m at erials are a very
im portant role in t he soil, t o im prove t he physical, chem ical and biological qualit y of soil. One of t he
im portant organic m at erial is m anure. Manure has a nut rient com ponent ( Tola et al., 2007) . Fuentes
and Chuj oy ( 2009) and Abdissa et al. ( 2012) states t hat the ideal am ount of m anure that is given is
15- 20 t ons/ ha t o spur the growth and yield of sweet potat o. This st udy is aim ed at test ing som e sweet

potat o clones of CI P- SEA and local clones wit h t he applicat ion of m anure is right for t he growt h and
yield of crops in t he lowlands. This st udy also t est ing t he adapt abilit y of som e clones of sweet pot ato
and m anure on the growth and yield of sweet potat o as well as t he int eract ion bet ween t he t wo

This research was conducted at t he Farm land of t he Facult y of Agricult ure Experim ent al Syiah Kuala
Universit y Darussalam , Banda Aceh, I ndonesia. The research was conducted from March t o Septem ber
2014. The sweet pot ato clones used com es from t he I nt ernat ional Pot at o Center- Sout h East Asia ( CI PSEA) Bogor, nam ely: CI P- LSQ, CI P- 1945, CI P- MAN, CI P-153, CI P- CER, CI P-WHI - 5 and 2 Local clone
t he t uber beige and orange bulbs. The st udy uses decom posed cow dung as a m anure at a dose of 20
t onnes/ ha. The t ools used in this study is a tool cult ivat ion, calipers, scales and oven.
This st udy uses a Discrete Random Design ( split plot design), t he pat t ern of random ized block design.
The m ain plot is dose of m anure t reatm ent ( 2 level: cont rol ( P0 ) and m anure of 20 t on/ ha ( P1 ) ) and
sub plot is t he t reat m ent of t ypes of clone ( 8 t ypes: CI P-LSQ ( K1 ) , CI P- 1945 ( K2 ) , CI P-MAN ( K3 ) , CI P153 ( K4 ) , CI P-CER ( K5 ) , CI P-WHI -5 ( K6 ) , Bulbs beige ( K7 ) and Tuber orange ( K8 ) ). From t hese t wo

fact ors obtained 16 unit s of t rial wit h t hree replicat ions. Each experim ent al unit consisted of five plant
sam ples.
At t he im plem ent at ion of t his st udy, land preparat ion st arts wit h t he clearing of weeds, and loam ing of
soil wit h a hoe, em beding weeds. Plots were prepared wit h a 500 cm long, 100 cm wide, 40 cm high,
and 60 cm dist ance bet ween plots. Cut teges of sweet potat o ( lengt h 25 cm ) were planted 1
cut tage/ hole wit h a space of 25 cm x 40 cm plant s m aint ained by replant ing bad plants at 2 week
aft er plant ing (WAP) , weed cont rol carried out at 4, 8, 12 and 16 weeks and the reversal of t he plant
perform ed at 4, 8 and 12 WAP. Harvest ing is done at t he t im e t he plant was 18 MST, by pulling t he
sweet pot ato plant, t hen dig beds and t ubers are taken and collect ed. Bulbs are grouped based on
observed t reat m ents and put in a plast ic cont ainer or burlap bags.
The param eters observed in this study were: percent age of growt h ( 3 WAP) , growt h vigorous
( st rength grow) of plant s ( 6 WAP) ( scale of 1- 3, where 1 = whit hout vine, 2 = 1- 3 vines, and 3 =
m ore t han 3 vines), fresh weight biom ass per plant ( g) , dry weight of biom ass per plant ( oven- dried
at 70° C for 48 h) ( g), t uber fresh weight per plant (g) , t uber air dried weight per plant ( air dried for 6
days) (g) , larger tuber yield ( t ons/ ha) , sm aller t uber yield ( t on/ ha) (Criterion for larger t uber size is
greater t han 200 g, while t he sm aller t uber size is less t han 100 g), t otal t uber weight ( t on/ ha), t otal
biom ass fresh weight and general evaluat ion t ubers t he t im e of harvest ( a score of 1- 3, a value of 1 =

Results a nd D iscussion
1. Effe ct of clones on t he Grow t h and Yie ld of Sw ee t Pot a t o

Analysis of variance ( F t est ) showed t hat clones significant by effect t he percent age of life, growt h
vigorous, fresh biom ass weight per plant , dry biom ass weight per plant, t uber fresh weight per plant ,
air dried weight of t uber per plant, weight of large t ubers per hect are, t he weight of sm all t ubers per
hect are, tot al biom ass weight per hectare, t he tot al weight of t uber per hectare and general
evaluat ion t ubers. Table 1 shows t hat t he best sweet potat o plant growt h t reatm ent was found in CI P513 clone ( K4 ) . The clones suspected t o have high environm ent al adapt abilit y for fut ure growt h. Types
of clones adaptable t o t he environm ent is expect ed t o grow bet ter. The best sweet potat o crop
product ion was found on clones CI P- LSQ ( K1 ) .
Ta ble 1 . Average percentage of growt h (PG) , growth vigorous ( GV), fresh biom ass weight per plant
( FBW) , dry biom ass weight per plant ( DBW) , t uber fresh weight per plant ( TFW) , air dried weight of
t uber per plant ( ADWT) , t he weight of larger t ubers ( WLT) per hectare, sm aller t uber weight per
hect are ( STW) , tot al fresh biom ass weight per hect are ( TFBW) , t ot al tuber weight per hectare ( TTW)
and the general evaluat ion of the tubers ( GET)
According to Sim at upang ( 1997), higher product ion of a clone is caused by the adaptabilit y of t he
clones t o t he environm ent. Therefore, environm ent al fact ors such as clim ate and soil are great ly affect
crop product ion. According t o Adiyoga et al. ( 2004) , the use of superior sweet potat o clones wit h high
yielding and high adapt at ion capacit y t o t he environm ent is one way t o increase t he product ion of
sweet pot atoes. I n addit ion to environm ental fact ors, growt h capacit y of clones are also influenced by
genet ic fact ors. According Riani et al. ( 2001) , each individual clones growt h and result s are vary
according genet ic influences, where genet ic influences are inherited by t he descendant s of each clone.
Sadj ad ( 1993) also stated t hat t he growt h capacit y are difference between t he different clones and

det erm ined by genet ic factors. Manrique and Herm an ( 2002) showed t hat a very close int eract ion
bet ween clones and t he environm ent in a given locat ion will not be t he sam e at ot her locat ions, due t o
environm ent al fact ors t hat great ly affect t he appearance and yield of sweet pot at o. Growt h and yield
of sweet potat o is highly dependent on t he clone and condit ions of plant growt h.

Descr ipt ion: Figures followed by t he sam e let t er on t he sam e line ( capit al let t er v ert ical and sm all let t er horizont al)
had no significant difference at 5% lev el ( Duncan Mult iple Range Test ) . Figures in brack et s are t he dat a
t ransform at ion ( X + 0.5) ½ wit h out m anure ( P0 ) .

This is suspect ed that t he clones CI P- LSQ ( K1 ) has the absorpt ive capacit y of nut rient cont ained in t he
soil. This is in confirm ed wit h Purwo ( 2007) t hat a plant requires t he t ype, dose, and t he opt im um
concent rat ion t hat could t rigger a m axim um of product ivit y and growt h. Sarwono ( 2005) st at es t hat
t he am ount of nut rient s needed t o form different part s of plants is different for each t ype of plant and
even for the sam e t ype of plant.
Conclusions
1. The best growt h of sweet pot at o was found on CI P- 153 clone, while t he best yield was found
on CI P- LSQ clone.
2. The best growt h and yield was found on t reat m ent wit hout m anure.
