olanum procumbens Lour. is a traditional medicinal plant known
for its rich glycoalkaloid content. This research aimed to determine
the suitable types and application rates of microbial organic
fertilizers to enhance yield and glycoalkaloid content in Solanum
procumbens Lour. A two-factor experiment was conducted using
a Split-Plot Design (SPD) with three replications. The main plots
included four types of microbial organic fertilizers (HD301,
HD302, Komix-BL2, and HCMK7), while the sub-plots involved
three application rates (2, 4, and 6 tonnes/ha per crop). Various
parameters were measured, including fresh and dry biomass
per plant, fresh and dry yield per ha, glycoalkaloid content, and
glycoalkaloid yield across two cropping cycles. The results indicated
that applying HCMK7 at a rate of 6 tonnes/ha per crop produced
the highest outcomes: in the initial crop, a fresh weight of 255.2 g
and dry weight of 111.1 g per plant, fresh yield of 15.77 tonnes/ha,
dry yield of 6.99 tonnes/ha, glycoalkaloid content of 0.70%, and
glycoalkaloid yield of 48.97 kg/ha. In the ratoon crop, the same
application rate yielded a fresh weight of 282.5 g and dry weight
of 134.6 g/plant, fresh yield of 17.62 tonnes/ha, dry yield of 9.21
tonnes/ha, glycoalkaloid content of 0.76%, and glycoalkaloid yield
of 70.39 kg/ha. The highest average glycoalkaloid content (0.73%)
and total glycoalkaloid yield (119.36 kg/ha) across both crops were
also recorded at this application rate.
