INFLUENCE EFFECTIVE USE OF MICROORGANISMS 4 (EM4) AND GIVING LIME (GYPSUM WASTE) ON THE GROWTH AND PRODUCTION OF CORN ( Zea mays L. ) KING VARIETY

Abstract

Good corn plant growth can support higher production. Farmers use various planting distances to achieve the right spacing and increase sweet corn production. to increase corn production can also be done by adding Biological Agents (MOL / EM4) and Lime Application (Gypsum Waste). By knowing the dosage of Biological Agents (MOL / EM4) and Lime Application (Gypsum Waste) which appropriate expected will can improve growth and corn plant production. The aim of this study was to determine the effect of the use of Biological Agents (MOL / EM4) on the growth of corn plants (Zea mays L). The tools used in this study were: hoes, sickles, measuring tapes, scales, tractors, diesel fuel, and stationery. The materials used were corn seeds, lime (gypsum waste), and MOL/EM4. Data analysis used statistical analysis. fingerprints variety (anova) And analysis testing different between treatment tested with Duncan's significant difference test at a 5% confidence level.

The results of the study showed that the treatment of providing MOL / EM4 with the provision of lime (gypsum waste) had a significant effect on the height of corn plants at 20 HST, the height of corn plants at 40 HST, the number of leaves at 20 HST, the number of leaves at 40 HST, the weight of dry cobs per plot, the weight of dry cobs per plot. dry per plant, And weight pipilan dry per plot. Dose MOL / EM4

15 cc/plot (M3) provided the best growth and production results. There was a significant interaction between the application of lime (gypsum waste) and the MOL/EM4 dosage treatment on the average dry cob weight per plant, namely in the P2M3 treatment, which is a combination of lime (gypsum waste) application. Dose 15 g/plot with MOL/EM4 15 cc/plot.
