The objective of this study is to observe growth pattern of grand rapids(lettuce) according to different experimental conditions for minimizing its growth period such as composition of nutrient, irradiation time of light source and cultivation mode.
The culture of water spray type using seeds of grand rapids was performed during growth period of total 50 days. Experimental conditions consist of five compositions of nutrient (PW 0.5 mS/㎝, PW 1.0 mS/㎝, PY 0.5 mS/㎝, PY 1.0 mS/㎝, PW 2.0 mS/㎝) and three irradiation times of light source (12h(on) / 12h(off), 18h(on) / 06h(off), 24h(on) / 00h(off)). Illumination was adjusted to ratio of 7:1:1 of red, blue and white color, respectively. Indoor environmental condition for cultivating grand rapids is as follows: temperature (19-22℃), relative humidity (60-70%) and carbon dioxide (1,000-1,200 ppm). The data were obtained from five iteration tests.
The maximum growth level was observed in the experimental condition of 18 hr(on) / 06 hr(off) and PY 1 mS/㎝ for 1st week of cultivation period, 24 hr(on) / 00 hr(off) and PY 1mS/㎝ for 2nd week of cultivation period, and 24 hr(on) / 00hr(off) and PW 1 mS/㎝ for 3rd week of cultivation period, respectively. On the contrary, the minimum growth level was observed in the experimental condition of 18 hr(on) / 06 hr(off) and PW 0.5 mS/cm for 1st week of cultivation period, 12 hr(on) / 12 hr(off) and PW 0.5 mS/㎝ for 2nd week of cultivation period, and 12 hr(on) / 12 hr(off) and PY 0.5 mS/㎝ for 3rd week of cultivation period, respectively. Based on the results obtained from this study, it is concluded that the growth level of grand rapids varied with different irradiation time of light source and composition ratio of nutrient according to cultivation period.
