Abstract

Microgreens are young plants (7-21 days), with the characteristic is the development of cotiledon leaves. Microgreens have more nutritional content than adult vegetables. Microgreens are often served as salads, garnish, sandwich complements, and juices. There are many types of crops that can be cultivated as the microgreens, one of them is mustard. Microgreens is an option in the middle of a pandemic to meet the nutritional needs of the body. It can be done simply without fertilizer, in a small space, nor excess light. In the indoor cultivation of mustard microgreens there are several things to be noted, such as the use of lamp as a substitute for sunlight, and the planting media that is suitable for the growth of mustard microgreens. The use of LED lights in indoor cultivation is nothing new, it can be saving in the use of electricity, also released heat energy is less likely to damage plants. In the use of LED, the setting of irradiation time is carried out, considering the need for light of each plant varies, the selection of planting media is also needed. Organic planting media as one of the options that can be used in the cultivation of mustard microgreens. It contains the organic material that can improve the physical, chemical, and biological of the soil that can support plant growth. It is considered more efficient than the use of rockwool, because it can be used many times in the process of cultivating microgreens. This study aims to evaluate the effect of LED photoperiod, planting media composition, and their interaction to the growth and yield response of mustard microgreens. The research was carried out in October – November 2020 at Timbangan, North Indralaya district, Ogan Ilir regency, South Sumatera. The study was prepared using a Split-Plot Design which consisted of 2 factors and 3 replications. The main plot is the LED photoperiod, consisted of L0 = for 0 hour/day, L1 = for 10 hours/day, and L2 = for 20 hours/day. The subplot is the planting media composition, consisted of M1 = 100% soil, M2 = 100% compost, M3 = 50% soil + 50% compost (v/v), M4 = 50% soil + 50% cocopeat (v/v), and M5 = 50% compost + 50% cocopeat (v/v). The observed variables were light intensity, air temperature, percentage of germination, plant height, root length, plant fresh weight, root fresh weight, and media pH value. The data of this research were analyzed using ANOVA at 5% real level and tested further with 5% LSD test. The use of LED grow light gave a relatively small light intensity that ranges from 284-384 lux. The highest air temperature is obtained in the planting room box with a duration of 20 hours / day (L2) ranging from 25.8-29.7 °C. Based on the results of the study showed that the LED photoperiod affected the plant height, and the planting media composition affected all the observed variables except root fresh weight and percentage of germination, also the interaction both of the treatments significantly increased the plant height and root length. The treatment of LED photoperiod for 0 hour/day (L0) gave quite good results to the growth of mustard microgreens, but physically plants undergo ethiolasi with yellowing leaves, thin stems, and tend to look withered due to lack of light. The composition of planting media containing compost gave higher yields than soil use or cocopeat mixture to the results of microgreens mustard. The results suggested that the cultivation of mustard microgreens in LED photoperiod for 10 hours/day with a composition of 50% soil + 50% compost (v/v) could give better results against the increased plant fresh weight of mustard microgreens. The organic planting media composition can be used repeatedly in several periods of mustard microgreens cultivation.
