Pertumbuhan dan Produksi Jagung Pulut Lokal Sulawesi Selatan yang Ditanam di Polibag Pada Berbagai Kombinasi Perlakuan Pupuk Organik

Abstract

Research has been carried out through the utilization of organic fertilizer to improve the productivity of local maize
cultivar originated from South Sulawesi. The study was conducted at the research station of Research Center for Biology,
Cibinong Science Center. Corn seed were planted in polybag containing mixture of soil and compost, 6 and 2
kg, respectively. The research were carried out by Randomized Complete Block Design arranged in factorial experiment
with four replications. The first factors are three types of local maize namely A: rice corn (pulut beras, Batara
Koasa), B: waxy corn (pulut biji, Batara Kamu), C: pulut hibrida (hybrid cultivar). The second factors are 14 combination
treatment as a mixture of LIPI organic fertilizer (Beyonic-StarTmik, Bio121, EM-121 and MegaRhizo) and
anorganic NPK fertilizer. The variables observed were plant growth and production. The results showed that the
hybrid cultivar had higher total corn yield productivity compared to the local one, although hybrid cultivar has
smaller plant biomass. Waxy corn (B) accession showed the weight, length and diameter of cob, and also the weight
of 100 grains larger than rice corn (A). Fertilization treatments significantly affect the corn-cob productivity which is
includes the weight, length, and diameter units. Fertilization treatments such as EM-121 + (½ dose of NPK), BIO-
121 + (½ dose of NPK), and Beyonic + (¼ dose of NPK) showed a good effect on plant, and it was not significantly
different with 100% NPK (full doses of NPK). The three corn cultivar showed different responses to fertilization
treatments.
