Abstract
The study entitled “Effect of LED Lights on Fodder Production in Pipe Framed Hydroponic Structure” was carried out at instructional Farm, department of Farm Structures, College of Agricultural Engineering and Technology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. This study was carried out to determine the effects of different colour light emitting diodes (LED) duration and intensity levels of LED on the growth of wheat and maize crops in pipe framed hydroponic structure.
The field experiments were laid out in factorial randomized block design with 19 treatments and 3 replications of each treatment for maize and wheat crop. The treatments consisted of two LED’s reddish purple and white, three durations viz., 4 h, 8 h and 12 h and three LED light intensity levels viz., 480 lux, 740 lux and 930 lux along with control treatment. Seeds of wheat and maize were sown in plastic tray with 350 g and 500 g seeds per tray, respectively. The irrigation was scheduled daily after 1 h for 1 min as automatic timer was connected with motor pump for irrigation
The maximum plant height, fresh weight, chlorophyll content, crude protein, crude fiber, crude fat, dry matter and ash content of wheat using reddish purple LED was found to be 23.35 cm, 2.278 kg, 33.682 mg/g, 14.66%, 15.789%, 2.648%, 17.2% and 2.6%, respectively. The maximum plant height, fresh weight, chlorophyll content, crude protein, crude fiber, crude fat, dry matter and ash content of maize using reddish purple LED was found to be 23.807 cm, 2.672 kg, 25.226 mg/g, 12.733%, 14.659%, 2.448%, 16.79% and 2.667%, respectively.
The maximum plant height, chlorophyll content, crude protein, crude fiber, crude fat, dry matter and ash content of wheat using 12 h LED duration was found to be 24.006 cm, 33.989 mg/g,14.44%, 15.40%, 2.648%, 17.75% and 2.806%, respectively. The maximum fresh weight wheat using 8 h LED duration was found to be 2.366 kg. The maximum plant height, fresh weight, chlorophyll content, crude protein, crude fiber, crude fat, dry matter and ash content of maize using 12 h LED duration was found to be 24.144 cm, 2.749 kg, 25.356 mg/g, 12.911%, 14.939%, 2.448, 17.346% and 2.516%, respectively.
The maximum plant height, fresh weight, chlorophyll content, crude protein, crude fiber, crude fat, dry matter and ash content of wheat using LED light intensity of 930 lux was found to be 24.683 cm, 2.509 kg, 33.804 mg/g, 14.14%, 15.68%, 2.74%, 18.317% and 2.833%, respectively. The maximum plant height, fresh weight, chlorophyll content, crude protein, crude fiber, crude fat, dry matter and ash content of maize using LED light intensity of 930 lux was found to be 24.689 cm, 2.843 kg, 26.006 mg/g, 12.511%, 15.217%, 2.544%, 17.907% and 2.543%, respectively.
It was found that reddish purple LED, 12 h duration of LED and LED light intensity of 930 lux showed better desirable results compared to white LED and control, 4 h and 8 h duration of LED and light intensity of 740 lux and 480 lux.
Description
The experiments were conducted at Instructional Farm, Department of Farm Structures, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the month of January to March (2019). The field experiments were laid out in factorial randomized block design with 19 treatments and 3 replications of each treatment for maize and wheat crop. The treatments consisted of two LED’s reddish purple and white, three durations viz., 4 h, 8 h and 12 h and three LED light intensity levels viz., 480 lux, 740 lux and 930 lux along with control treatment.
