ABSTRACT

A field experiment entitled “Effect of foliar application of nano urea on growth and yield of fodder maize” was conducted at Dryland Farm, S.V. Agricultural College, Tirupati campus of Acharya N.G. Ranga Agricultural University, Andhra Pradesh, India during rabi, 2023-24. The experiment was laid down in the randomized block design and replicated thrice. Significantly higher values of plant height, leaf area index, green and dry fodder yields were recorded with application of 100% of RDN @120 kg N ha-1 + two sprays of nano urea @ 4 ml l-1 at knee high and tasselling stages, which was found to be on par with 100 % RDN through urea in three splits (33 % basal + 33 % KH + 33 % TS). Significantly lower values were realized with control.

KEYWORDS: Green fodder yield, Dry fodder yield, Knee high stage, Tasselling stage, Recommended dose of nitrogen.
