Abstract:
The study investigated
agronomical and qualitative features of
Indian mustard in a semi-arid region from
Iran. Field trials were designed in split plot
arrangement based on a Randomized
Complete Block Design with three
replicates at the Agricultural Faculty of
Takestan, Iran. In the study, plant height
(cm), the number of seeds in the siliqua
(seed/siliqua), the number of siliquae in the
plant (siliqua/plant), seed yield (kg/ha),
biological yield (kg/ha), thousand-seed
weight (g), harvest index (%), oil content
(%) and oil yield (kg/ha) were determined.
The all growth and yield parameters of
mustard plant were significantly affected by
nitrogen fertilization. All the parameters,
except for harvest index (HI), were
drastically affected by used densities. The
highest seed yield and oil yield (2961 and
1159 kg/ha, respectively) were obtained for
the crop utilized with 200 kg N/ha in plots
with 80 plants/m2. The maximum oil content
(43.97%) was recorded in the lowest plant
density (80 plants/m2) and nitrogen
application level of 50 kg/ha. Results
suggest that in semi-arid region of Takestan,
researchers must direct their selection
treatments to increase oil quality of Indian
mustard.
