Abstract
A field during the rabi season of
2024-25 at the Agronomy Research Farm of Vivekananda Global University, Jaipur.
The experiment consisted of four spacings (17.5, 20.5, 22.5, and 24.5 cm) in
main plots and four nitrogen levels (75, 100, 125, and 150 kg N/ha) in
subplots. The 16 treatment combinations were tested in a randomized block
design with three replications. Based on research investigation, it was found
that the application of row spacing significantly improved plant stand, yield
attributes, and harvest index. However, row spacing of 17.5 cm was
significantly superior to plant stand, growth parameters, and biological yield
as compared to both 17.5 and 24.5 cm. Dry matter accumulation, number of
tillers, all the yield attributes, grain yield, and biological yield increased significantly
up to 125 kg N/ha. However, plant height and straw yield increased
significantly up to 150 kg N/ha. At higher row spacing of 17.5 and 22.5 cm
produced statistically similar yield, whereas at 17.5 cm row spacing produced
significantly more grain yield than 22.5 and 24.5 cm.
