Abstract

Abstract: Microgreens are young vegetable greens that harvested when the cotyledons have fully developed, which usually occurs at the age of 7-14 days after germination. Kenikir is a medicinal vegetable plant that has many health benefits. Microgreens cultivation in Indonesia is increasing along with public awareness of health, but the information about the best planting media for the cultivation of microgreens is still very limited. This research aimed to study the effect of a combination of manure and biochar on the growth and N uptake of kenikir microgreens. The research conducted in Mojogedang, Karanganyar, Central Java using a factorial complete randomized block design (RCBD). The first factor is the type of manure consisting of control, cows, and goats. The second factor is the type of biochar consisting of husks, coconut shells, and rice straw. The results showed that the combination of manure and biochar treatment can increase plant N uptake. The combination of cow manure with various types of biochar produces the highest N uptake. Cow manure combined with husk, coconut shell and straw biochar successively produced N absorption 1.72%, 1.81% and 1.91%. However, the large uptake of N does not influence the growth of microgreens.. The variety of manure did not significantly affect the growth (plant height, leaf area, and root length) of kenikir microgreens. Biochar type affects plant height. Husk biochar increases plant height by 16.29%, and coconut shell biochar increases plant height by 9.03% compared to straw biochar.
