Abstract:
A Research on Performance evaluation of hydroponic fodder production system for
jowar crop at different light conditions was conducted in PFDC building of Kelappaji College
of Agricultural Engineering and Technology Tavanur. The objective of research work was to
evaluation of hydroponic fodder production system for Jowar crop under different light
conditions.
The fogger irrigation was selected as the water application method. Artificial light
source of LED red (L1), LED blue (L2) and LED red + blue (L3) were taken for the study.
Statistical analysis was conducted to understand the significance of different treatments used
in the experiment.
The highest yield was observed in treatment under LED red + blue (0.712 kg/tray) with
the highest water use efficiency (728.33 kg/m3) compared to other treatments. Seed to fodder
ratio obtained was 1: 4.
Higher growth of green fodder under artificial light source can be attributed to the
continuous supply of energy and also the uniform distribution of water by fogger irrigation
which maintained favourable condition for fodder growth. Results clearly shows that growing
green fodder with artificial light source (LED red + blue) can be recommended to farmers for
achieving better growth of green fodder for domestic animals.
