Abstract
Effect of some fertilzer treatments on sesame under sandy soil
condlt\ons.
A field eJ<P9riment of split spilt plot design was conducted in
Ismailia Agricultural Research Station Farm in two consecutive
growlh seasons of 1994 and 1995 to study”,e effeCI.of faf11\yard
manure (FYM) application (zero and 10 m
3
fed.-
1
FYM) and
potassium (24. 48 and 721<9K20 par fed.) and nitrogen (30.
45
and
60 kg N par fed.) fertilizatlon treatments and ”’elr possible relevant
interactions on sesame cv. Giza 32 growth and yield as well as ”,e
uptake of N. P and K. The results obtained are concluded as fo\low
S
:-
A .. Plant growth:
1 _APplication of farmyard m8f1l.l”9(FYM) signifiC8/1lly increased drY
weight (D.Wt) in the first Vegetative sample at (60 dayS after sowing
(60 DAS) and plant height, rorobef of leaves and roro
ber
of capsules
per plant in ”,e second vegetative sample (90 DAS).
2 _ APplication of potassium fertilizer slgnifiC8/1lly Increased plant
heiglll.. roro
ber
of leaves and drYweiglll.(D.Wt) in ”,e two samples
(60. 90 DAS). in addation. number of capsules per plant was
noosignlfieantly increased in lI1e second sample.
63
3 _Nitrogen fertilizer rate up to 45 kg per fed. significantly increased
plant height and OWl. in \he two samples as well as \he rum
bef
of
capsules per plant in \he second sample. hawever,\he number of
leaves per plant in \he second sample w8S significantly Increased
wi\h nitrogen fertilization up to 60 kg N per fed.
4 _ All possible FYM)( K x N interactions caused significant effects
on the tested growth characteristicS.
B • uptake of NPK :
1 _ APplication of FYM nonsignlficantly increased NPK uptake in the
first sample (60 OAS). however. \he effeCI. was significant on \he
uptake of P and K in \he second one (90 OAS) .
2 _ The K fertilization up to 48 kg K20 per fed. caused a
nonsignificant increase In N _uptake bUt was significant bY affected
P and K uptake at bOth 60 and 90 OAS .
3 _ The N-fertilization up to 45 kg N per fed. significantly increased
N-uptake In the first sample (60 oAS). hOWever.\he increase was
significant wi\h 60 kg N per fed., In \he second sample (90 OAS) .
There was no significant difference In p-uptake wi\h 45 kg N per fed.
in \he two samples. moreover. K-uptake was significantly increased
wi\h N application up to 60 kg per fed. in \he two samples,
64
4 _ The Interaction effect between FYM , K and N was significant on
the investigated characters.
c . Yield attribufes :
1 _ All yield attributes were significantly increased by FYM
application wi1\11\1eexception of plant height .
2 _ The K-fertitization rate of 24 kg K20 per fed. had a significant
effect on plant height, number of capsules per plant and weight of
seeds per plant. However, weight of slraw per plant was significantly
affected w,th K up to 48 kg K20 per fed.
3 _ The N_fertilization up to 60 kg Nlled. led to an increase In all
tested yield attributes except for 100ll-seed
weight.
4 _ The FYM x K interaction shOwed !hat K fertilization up to 48 kg
K2
0
per fed. In combination wi1\1 FYM Increased plant height,
number of capsules per plant and 1000-
seed
weight
5 _ The FYM x N up to 60 kg N per fed. increased tUTl
ber
of
capsules and weight of capsules, seeds and slr8W per plant.
6 _The treatment of 24 kg K20 per fed. + 45 kg N per fed. Increased
plant height. number of capsules per plant and !he 100llseed
weight.

meanwhile, weights of bOlh seeds and straw per plant were
increased by Ihe application of 24 kg K20 + 60 kg N per fed.
7 • APpilcati
on
of F’{M wilh K and Nfertilizers at Ihe rate of 24 kg
K2
0
and 60 kg N per fed. improved \he major yield attribUtes.
D. Yield:
1 • APplication of F’{M Significantly inc:reased each of seed. straw
and oil yield per fed. as well as seed oil percentage.
2 • seed and seed oil yields were significantly increased whell K
fertilizer was applied at Ihe rate of 48 kg K20 per ted., while Ihe rate
of 24 kg K2
0
per fed. significantly increased slraw yield and seed oil
percentage .
3 _seed. straW and oil yieldS were increased by N fertilization, while
seed oil percentage was not affected. The rate of 60 kg Nper fed.
gave Ihe highest seed and seed oil yields.
4 • F’{M x K Interaction significantly affected Ihe yield. ’The best
lreatJ1\9
nt
was F’{M + 24 Kg K20 per fed. which gave \he highest
seed (3.058 ardeb per fed.) , straw (817 kg per fed.) and oil (2OOkg
per fed.) yieldS as well as seed oil percentage (56.49 %)
respecU\le\y.

5 _ The FYM x N interaction had a significant effeCt on yield. The
highest values of seed (2.676 ardeb per fed.), straw (843 kg per
fed.) and oil (173.73 kg per ted.) yields resulted by Nfertilization at
the rate of 60 kg N per fed. without FYM appU cati on.
6 _ The application of 48 kg K20 + 45 kg N per ted., economically
increased seed and seed oil yields as well as seed oil percentage.
On contrast. application of K and N fertilizers at the rate of 48 kg
K2
0
and 60 kg N per fed. gave the highest s1raw yield (884 kg per
fed.) .
7 _The FYM x K x N interaction had a significant effect on yield. The
application of 48 kg K20 and 60 kg N per fed. without FYM, gave
me highest seed (3.127 ardeb per fed.) and s1raw ( 898 kg per fed.)
yields. In the meantime, FYM application wilh 24 kg K2
0
and 30 kg
N per fed. gave Ihe highest seed all yield (3.293 ardeb per fed.) and
seed oUpercentage (57.48 %) .
