Abstract
A study was conducted for “Development of hydroponic system for growing maize as fodder
crop” at the demonstration area of the Department of Soil and Water Engineering, PAU,
Ludhiana during the year 2020-21. A hydroponic system was designed and fabricated
[1251mm (length) x 2753mm (height) x 813mm (width)] to study the different stages of
growing maize as fodder crop for seven days. There were 12 treatment combinations under
this study, with three levels of irrigation i.e. I1, I2 ; two nutrient application levels i.e. F1and
F2, and two levels of light intensities i.e. L1 and L2.The treatments were laid in a complete
randomized design with three replications to analyze the recorded data statistically. The data
recorded under different treatment combinations indicates that the maximum yield was
obtained under the treatment I3F2L2 as 3.61 kg per tray. Low level of irrigation frequency and
nutrient application level produced more fodder yield as compared with medium and high
levels. Higher water use efficiency and nutrient use efficiency were recorded under treatment
combination of I3F2L2 as 1.42 and 27.5 respectively. Under quality parameters, crude protein
was found to be 18.89 per cent and in vitro digestibility was high as 98 per cent. Economical
analysis of the developed system was performed and on the basis of B:C ratio as 1.27:1 the
present study is economically viable and technically feasible for production of maize as a
fodder crop under a hydroponic system.
