Abstract:
At the Dryland Farming Research Station, Arjia, Bhilwara, MPUAT, Udaipur a field investigation was carried out during Kharif, 2022. The investigation was laid out in Randomized Block Design (RBD) made up of eight treatments which were replicated four times. The results revealed that the application of T₅ (75% RDN + RD-PK + nano nitrogen @ 4 ml/l and 0.3 g/l at 30 and 60 DAS) make out significantly higher growth attributes of plant height, dry matter accumulation and leaf area index, and yield attributes of number of cob/plant (1.63), number of grain/cob (519.0), grain weight/cob (201.8 g), cob length (19.2 cm) and teat weight (237.0 g) as well as grain (52.5 q/ha), stover (84.7 q/ha) and biological yield (137.2 q/ha) over control. Even so, it remained statistically on par with treatment T₈ (50% RDN + RD-PK + nano nitrogen @ 4 ml/l and 0.3 g/l at 30 and 60 DAS). The finding of this experiment shows that one-half recommended dose of chemical nitrogen fertilizer can be turn down by application of nano nitrogen which may reduce detrimental effect of chemical fertilizers.
