Abstract

This study was carried out to investigate the effects of near ultraviolet ray-absorbing(UVA) film on growth and yield in mother fern green asparagus(Asparagus officinalis L.) semi-forcing cultivation. We also evaluated the durability of its ability to absorb near ultraviolet rays. Comparing the effects of using polyethylene and UVA film showed few differences in the values of illuminance, temperature, yield, color and brix of spears in the green house. The ratio of growth in the main stem was increased and the number of branches was decreased by pinching off the top when the plants were cultivated in a green house covered with UVA film. The ability of UVA film to absorb near ultraviolet rays decreased each year.
