Abstract:
The application of nutrient solution to the foliage of plants acts as an alternative way to fertilize crops. The study was conducted at Agricultural College and research institute, Madurai (semi-arid region of Tamil Nadu) 2022 to find out the effect of supplemental foliar application of macro and micro nutrients of two different rice varieties under drip fertigation (an aerobic soil condition). The experiment was laid out in split plot design with three replications. In main plot, two rice varieties viz., CO-54 and ADT-53; and in subplot five foliar application treatments along with no spray treatments were taken for experimentation. The result of the study indicated that 100% RDF of NP and K through fertigation combined with foliar application of 1% urea+2% DAP+1% KCl at panicle initiation and 10 days later produced higher plant height and grain yield when compared to other foliar application treatments. Among different varieties tested, Co-54 performed well and produced higher grain yield (5509 kg ha^-1) than ADT-53.
