SUMMARY

A factorial experiment was conducted at New area Farm, Department of Forage crops, Tamil Nadu Agricultural University, Coimbatore, during October – December 2017 to study the effect of different foliar nutrition spray on hydroponically grown fodder crops. The treatments included two factors viz. crops- fodder maize (C1), grain maize (C2), grain cowpea (C3) and horse gram (C4) and foliar nutrition- control (without any spray) (N0), 19: 19: 19 @ 1% (N1), DAP @ 0.5% + KCl @ 0.5% (N2), panchagavya @ 3% (N3), and vermiwash @ 1% (N4). From this study, it can be concluded that growing of grain maize with foliar application of 19:19:19 NPK @ 1% found to be technically viable and economically feasible option for attaining maximum green fodder yield and nutritional quality under hydroponic fodder production system.
