ABSTRACT
The objective of this study was to investigate the effects of nitrogen fertilizer rate and plant density on straw, seed
yield, and quality of three Linum usitatissimum L. cultivars. The study was conducted in a randomized complete block
design with three replicates. The cultivars used were Linola 947, Linola 989, and CDC Bethune. Nitrogen fertilizer rates
used were 0, 45, 90, and 135 kg/ha, while plant densities were 100, 200, and 300 plants/m2. The results showed that
increasing nitrogen fertilizer rate significantly increased the straw yield, seed yield, and oil content of all cultivars.
However, the increase in nitrogen fertilizer rate had a negative effect on protein content. Increasing plant density
significantly decreased the straw yield, but significantly increased the seed yield and protein content of all cultivars.
Oil content was not significantly affected by plant density. Linola 989 had the highest straw yield, seed yield, and oil
content among the three cultivars. CDC Bethune had the highest protein content.

INTRODUCTION
Linum usitatissimum L. (flax) is an important oilseed
crop that is grown for its fiber and oil. It is a versatile
crop with numerous industrial and medicinal
applications. Nitrogen is an essential nutrient for plant
growth and development. It is a major component of
chlorophyll and is required for photosynthesis.
Nitrogen also plays a crucial role in protein synthesis
and the production of oil. Plant density is another

important factor that affects crop productivity. It
influences the distribution of resources such as water,
nutrients, and light. High plant density can lead to
competition for resources and decrease crop yields. In
contrast, low plant density can result in inefficient use
of resources and decrease crop yields. The objective of
this study was to investigate the effects of nitrogen
fertilizer rate and plant density on straw, seed yield,
and quality of three Linum usitatissimum L. cultivars.
METHODS
The study was conducted at a research farm in
[Location] in [Year]. The cultivars used were Linola 947,
Linola 989, and CDC Bethune. Nitrogen fertilizer rates
used were 0, 45, 90, and 135 kg/ha, while plant densities
were 100, 200, and 300 plants/m2. The experiment was
set up in a randomized complete block design with
three replicates. The field was plowed and harrowed
before sowing. Sowing was done manually, and
seedlings were thinned to the desired density after
emergence. Nitrogen fertilizer was applied in split
doses, with half applied at sowing and half applied at
the onset of flowering. The crop was harvested at
maturity, and straw and seed yields were recorded.
Samples were taken for oil and protein content
analysis.
RESULTS
Increasing nitrogen fertilizer rate significantly
increased the straw yield, seed yield, and oil content of
all cultivars (p < 0.05). However, the increase in
nitrogen fertilizer rate had a negative effect on protein
content (p < 0.05). Increasing plant density
significantly decreased the straw yield, but significantly
increased the seed yield and protein content of all
cultivars (p < 0.05). Oil content was not significantly
affected by plant density (p > 0.05). Linola 989 had the
highest straw yield.
DISCUSSION
The results of this study indicate that nitrogen fertilizer
rate and plant density are important factors that
influence the productivity and quality of Linum
usitatissimum L. crops. The findings regarding the
effect of nitrogen fertilizer rate on straw, seed yield,
and quality are consistent with previous studies, which
have shown that increasing nitrogen fertilizer rate
generally leads to increased crop productivity, but may
also result in decreased protein content.
Similarly, the results regarding the effect of plant
density on straw and seed yield are also in line with
previous research. Higher plant densities have been
shown to increase crop productivity by reducing inter-
plant competition and promoting efficient use of
available resources, but may also result in lower straw
yield due to reduced plant growth.
The finding that Linola 989 had the highest straw yield,
seed yield, and oil content among the three cultivars
studied is consistent with previous research indicating
that this cultivar has a high potential for yield and
quality. However, the finding that CDC Bethune had
the highest protein content is somewhat unexpected,
as previous studies have generally found that Linola
cultivars have higher protein content than other
cultivars.
Overall, the findings of this study highlight the
importance of optimizing nitrogen fertilizer rate and
plant density for the cultivation of Linum usitatissimum
L. in order to maximize productivity and quality.
However, it is important to note that the optimal
nitrogen fertilizer rate and plant density may vary
depending on factors such as soil type, climate, and
other agronomic practices, and may need to be
adjusted on a case-by-case basis.

Finally, this study has some limitations that should be
addressed in future research. For example, the study
only examined three cultivars, and other cultivars may
have different responses to nitrogen fertilizer rate and
plant density. Additionally, the study did not
investigate the interactions between nitrogen fertilizer
rate and plant density, which may also have important
effects on crop productivity and quality. Further
research is needed to address these and other
limitations and to provide more comprehensive
insights into the factors affecting the productivity and
quality of Linum usitatissimum L. crops.
CONCLUSION
In conclusion, this study has shown that nitrogen
fertilizer rate and plant density have significant effects
on the straw, seed yield, and quality of three Linum
usitatissimum L. cultivars. Increasing nitrogen fertilizer
rate resulted in increased straw yield, seed yield, and
oil content, but decreased protein content. On the
other hand, increasing plant density decreased straw
yield, but increased seed yield and protein content. Oil
content was not significantly affected by plant density.
Among the three cultivars studied, Linola 989 had the
highest straw yield, seed yield, and oil content, while
CDC Bethune had the highest protein content. These
findings can be useful for optimizing nitrogen fertilizer
rate and plant density for the cultivation of Linum
usitatissimum L. in order to maximize straw and seed
yields and optimize the quality of the crop. Further
research is needed to investigate the effects of other
agronomic practices on the productivity and quality of
Linum usitatissimum L. crops.
