Abstract
The use of microbes’ research as biological fertilizers in order to increase corn production had been performed, but the analysis of farming business related to this matter has not been conducted. This research aimed to determine the effect of one of the biological fertilizers, which was Agrimeth, on the seeds of various composite corns to the growth factors, the productivity of corn farming in dry land, and the amount of income that was obtained. This research was conducted in Betung Village, Betung Sub-District, Banyuasin Regency, South Sumatra. The corn varieties used were Bima 10, Bima 19, and Sukmaraga. The results showed that the seed treatment of corn seeds with Agrimeth showed an improvement trend of plant height, number of leaves, cob length and diameter, weight of 100 dry shelled grains, dry shelled production, and R / C in each variety. The application of Agrimeth biological fertilizers increased corn farming in dry land with R / C 2.79; 2.65; and 1.82 for each Bima 10, Sukmaraga and Bima 19 varieties.
Highlights
Corn is an important commodity in the Indonesian food system that acted as the main food for some population in various regions
Corn was coated with biological fertilizer containing a microbial consortium of Azotobacter vinelandii, Azospirillum sp., Bacillus cereus, Bradyrhizobium sp., and Methylobacterium sp
The research result showed that corn seeds treatment with Agrimeth can improve the height of the plant
Summary
Corn is an important commodity in the Indonesian food system that acted as the main food for some population in various regions. Being the main food for the poultry industry, and basic ingredient for processed food industry (Suryana and Agustian, 2014). With such a large role in the food system in Indonesia, so the efforts to increase corn production and productivity must continue to be developed. The high cost of inorganic fertilizers including the inability to condition the soil and its influence on the environment has directed concern to other soil fertilization sources to increase corn production (Kumar et al, 2019). The use of compost was often constrained by a lot of needs so that it increased production costs significantly
