Abstract:

Brassica campestris L. plants are widely grown, including in Asian countries where the leaves are used to prepare Chinese sour pickled mustard greens. The potential benefits of the application of organic by-products and organic fertilizers in sustainable agricultural production have been shown in previous studies. Consequently, this study investigated the effectiveness of liquid worm fertilizer (LWF) and spent coffee grounds (SCG) individually and in combination on the growth of B. campestris. The results showed that LWF at the highest dose had positive effects on the growth and yield of B. campestris, but SGC had inhibitory effects.

The treatment consisting of composted SCG + triple of the standard dose of LWF resulted in the best plot yield with 3,866.7 g.plot-1, followed by the treatment of fresh SCG + triple of the standard dose of LWF, which produced a yield of 3,766.7 g.plot-1. The lowest yield (2,100.0 g.plot-1) was observed in the treatment of 1 kg.m-2 fresh SCG + no LWF. The interaction effect between SCG and LWF on the plot yield of B. campestris L. was significant (F(4,18) = 4.6; p = 0.01) demonstrating enhanced yield when both SCG and LWF were used in combination.
