abstract
The experiment was carried out at Raj Mohini Devi College of Agriculture and Research Station Ambikapur (C.G.) during the Kharif 2022-23 season. The experimental laid out in randomized block design with three replication and twelve treatments. Among the different nitrogen management practices, application of 100% RDN (3 split N application) had higher growth as well as yield attributes. Results revealed the 100% RDN (3 split N application) significantly increased all the growth attributes viz. plant height, dry matter accumulation, crop growth rate and the yield attributes viz., cob length, cob girth, number of grain rows cob^-1, number of grains row^-1, number of cobs. The highest cob yield (8961.2 kg ha^-1) and grain yield (7188.8 kg ha^-1) were also achieved under T₂: 100% RDN (3 split N application) followed by T₆: T₃ (75% RDN) + Nano urea two spray. T₁ (Control) was recorded lowest in term of growth attributes, yield attributes and yield. The highest net return and B:C ratio were also recorded under 100% RDN (3 split N application).
