Sweet corn farmers in Midang Village,
Gunung Sari District, West Lombok Regency are
currently still cultivating sweet corn using conventional
cultivation technology with a relatively high input of
inorganic fertilizers. This, if viewed from an economic
point of view, is a waste and from an environmental point
of view it is not environmentally friendly. Another
problem is the production of sweet corn which is still low,
not fresh and of low quality. Therefore, community
service activities (CSA) on "Application of
Bioameliorants Made from Local Raw Materials in Sweet
Corn Plants"were tried to provide solutions to problems
faced by farmers. The purpose of this CSA is to find out
the yield of technology transfer for the use of
bioameliorants made from local raw materials from the
Faculty of Agriculture University of Mataram Team to
the Farmers Group "Gapoktan Karya Usaha Bersama"
in increasing knowledge about the use of bioameliorants
and increasing sweet corn yields. The method used in
implementing this CSA is the training method followed by
practical work in the field by conducting demonstrations
and active participatory action research. The
demonstration plot method was carried out using a
randomized block design using four varieties of sweet
corn, namely V1: Bonanza variety, V2: Ganebo variety,
V3: Golden Boy variety, and V4: Exotic Pertiwi variety.
The result of the demonstration plot of the application of
bioameliorants made from local raw materials at a dose
of 25 t ha-1 on the Golden Boy variety gave the highest
plant height and number of leaves. Meanwhile, the
concentration of total N, soil available P, plant N and P
nutrient uptake, number of spores and percentage of
mycorrhizal colonization and the highest cob weight and
wet biomass were obtained in the Bonanza F1 variety.
With agricultural extension activities and discussions,
farmers' understanding of the application of
bioameliorants plus mycorrhizal biofertilizers in sweet
corn cultivation increased by 90%.
