Effects of led lights and growing environment growth and yield of mustard (Brassica juncea L.)

Abstract

Mustard are a nutritious vegetable and a popular plant in the world whose scientific name is (Brassica juncea). Quality and yield are affected by many factors such as water, nutrients, air humidity and light intensity. In particular, light is considered one of the most important factors, with wavelengths from 400 - 700 nm for plants to absorb. In addition, productivity and quality also depend heavily on the growing environment, including soil and hydroponic environments. Therefore, this study was conducted to evaluate the effective effects of LED lights and growing environment on increasing the yield of mustard. The Research results showed that growing mustard greens combined with LED lighting has had a positive impact on increasing the yield of mustard greens grown at Kien Giang University. Clean soil environment combined with LED lighting (three white lights and one red light) resulted in plant height reaching 44.82 cm, leaf number reaching 9.1 leaves, leaf length reaching 30.58 cm, leaf width 13.96 cm, chlorophyll index 20.63, fresh weight 71.5 g and dry weight 4.63 g for optimal results when growing green mustard. Growing mustard combined with LED lighting had positive impact on increasing productivity.
