Utilization of peanut shell waste and bio-slurry as organic fertilizer for sweet corn (Zea mays L. Saccharata)

The increasing demand for sweet corn (Zea mays, L.) in order to meet community
nutrition has encouraged farmers to make improvements to the cultivation system. One of the
important factors in the process of increasing sweet corn production is soil nutrients. Peanut
shell (Arachys hypogea. L.) and bio-slurry are organic waste, when they have undergone a
decomposition process they can be used as organic fertilizers. The aim of the study was to test
the correct dosage of peanut shells and the concentration of bio-slurry so that it could be used
as organic fertilizer for sweet corn plants. The research was conducted in the experimental
garden of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah
Malang from March to May 2020. It is a factorial experiment arranged in randomized groups,
the first factor is peanut shell dose: P1 = 10 tons / ha; P2 = 15 tons / ha; P3 = 20 tons / ha. The
second factor is the bio-slurry concentration: B1 = 100 ml/ L; B2 = 125 ml/ L; B3 = 150 ml/ L.
The results showed that there was an interaction between the peanut shell dosage treatment and
the bio-slurry concentration on the growth and yield of sweet corn. Dose treatment of peanut
shells on growth and yield variables of sweet corn is influenced by the concentration of bioslurry.
A combination of suitable treatment for growth and yield to sweet corn is peanut shell
dose 15 tons/ ha and bio-slurry concentration 125 ml/ L.
