Ameliorasi Tanah Gambut Dengan Berbagai Limbah Industri Terhadap Pertumbuhan Dan Hasil Dua Varietas Jagung (Zea mays L.)

Abstract

This study aims to get ameliorant formulations of various industrial wastes that most suitable for the growth and yield of maize varieties Earth-3 and NK-212 in peatland. Research design using a split plot with 12 combinations and each treatment was repeated 3 times. The main plot of treatment consists of: (V1): Pertiwi-3, (V2): NK-212. Treatment subplot consists of six formulations ameliorant, namely: F1 (60% TKKS + 20% ATKS + 10% dregs + 10% fly ash), F2 (60% TKKS + 10% ATKS + 20% dregs + 10% fly ash ), F3 (60% TKKS + 10% ATKS + 10% dregs + 20% fly ash), F4 (40% TKKS + 30% ATKS + 10% dregs + 20% fly ash), F5 (40% TKKS + 20% ATKS + 30% dregs + 10% fly ash) and F6 (40% TKKS + 10% ATKS + 20% dregs + 30% fly ash). The data obtained were statistically analyzed using analysis of variance (ANOVA) followed by HSD test. The result showed that the formulation of 40-60 % TKKS, 10-30 % ATKS, 10-30 % dregs and 10-30 % fly ash gave significant effect to variety and ameliorant formulation. Varieties significantly affect a male flowers and female flowers. The Formulation of ameliorant gave the significant effect on plant height and timing of male flowers and female flowers. Interactions both provide the same effect on all observed variables, such as the formed of cob production, the number of lines of neatly arranged and the seed is fully charged and the skin covering the cob well (± 98%) was conformity with description. The combination of Pertiwi-3 with F6 formulation was better used for peat soil because its able to accelerate the emergence of male flowers and female flowers, thus spurring the generative plant growth, by accelerating the maturation of seeds so as to accelerate the harvest.
