Pengaruh Aplikasi Kompos Granul Ela Sagu Diperkaya Pupuk Ponska Terhadap Sifat Fisik Tanah Dan Hasil Jagung Manis Di Inceptisol

Abstract

Background: the sago flour is the main result of the sago palm, while the byproduct or waste sago generally used for animal feed, compost in mushroom growing media, or as raw material for the plywood industry. Sago waste by the people of Maluku called ela sago can also play a role in improving soil fertility in this case improve the physical, chemical and biological soil after going through stages of processing into granules and granule enriched compost.
 Methods: The study design used was a randomized block design with three replications. The treatment consists of: without fertilizer (KGES1), compost granule 8 t ha-1 (KGES2), inorganic fertilizers (Urea, SP-36 and KCl) recommended dosage (KGES3), inorganic fertilizer + compost granule 8 t ha-1 (KGES4), ½ x doses of inorganic fertilizer + compost granule (8 t ha-1) (KGES5), 2 doses of inorganic fertilizer + compost granule 8 t ha-1 (KGES6), ½ x doses of inorganic fertilizer + compost granule 12 t ha -1 (KGES7) and 2 doses of inorganic fertilizer compost + 4 t ha-1 (KGES8).
 Results: Compost granules ela sago and inorganic fertilizer significantly affect the physical properties of soil that is heavy volume of land (0.80 g cm-3), a specific gravity of soil particle (2:30 g cm-3), soil porosity (7.77%), drainage pore fast (23:54%), slow drainage pores (8.83%), pore water is available (11.62%), and pore water is not available (11:31). While plant growth (plant height) and dry seed corn grain yield respectively by 249.17 cm and 7.85 tonnes ha-1. A combination of compost and inorganic fertilizer granule able to increase the yield of 30-47% compared with inorganic fertilizer or compost granule alone. Excessive inorganic fertilizer application did not show the result of increased dry seeds shelled corn is real. Based on these results, a reduction of half a dose of inorganic fertilizer combined with granulated compost 12 t ha-1 yield of dry shelled corn grain yield highest (7.79 t ha-1) or increase the yield of 32% of inorganic fertilizer application.
 Conclusion: Compost granules ela sago and inorganic fertilizer significantly affect soil physical properties ie soil bulk density (0.80 g cm-3), soil particle density (2:30 g cm-3), soil porosity (7.77%), soil macropore (23:54%), mesopore (8.83%), and micropore (11.62%). While plant growth (plant height) and dry seed corn grain yield respectively by 249.17 cm and 7.79 tonnes ha-1. A combination of compost and inorganic fertilizer granule able to increase the yield of 30-47% compared with inorganic fertilizer or compost granule alone. Excessive inorganic fertilizer application did not show the result of increased dry seeds shelled corn is real.

Effect of Cyanobacteria-Enriched Compost on Maize (Zea mays. L) Growth and Yield and Nutrient Uptake in Inceptisols

“…Agusni et al ( 2014) stated that organic matter might porously enter the soil ground, increasing the number of soil pores, affecting soil aggregates, and reducing soil bulk density. Organic matter in the soil increases macro and micro pore space, thus stimulating soil aggregate formation, which causes a decrease in soil bulk density (Habi, 2015).…”

“…Berat isi yang menurun akan menyebabkan banyaknya ruang pori makro dan pori mikro. Menurut Habi (2015) menjelaskan bahwa peningkatan ruang pori tanah terjadi karena bahan organik dapat memacu pembentukan agregat-agregat tanah yang diindikasikan dengan terjadinya penurunan berat isi tanah. Menurut Utomo (1995) bahwa peningkatan kandungan bahan organik tanah yang berfungsi sebagai bahan pengikat di dalam pembentukan agregat tanah sehingga pori aerase dan pori air tersedia tanah meningkat seiring dengan banyaknya kandungan bahan organik.…”

“…Kompos merupakan zat akhir suatu proses dekomposisi tumpukan sampah atau serasa tanaman dan termasuk pula bangkai binatang [12] . Limbah sagu yang oleh masyarakat Maluku disebut sebagai ela sagu, juga dapat berperan dalam memperbaiki kesuburan tanah dalam hal ini memperbaiki sifat fisik, kimia tanah dan biologi tanah setelah melalui tahap pengolahan menjadi kompos ganula dan ganul diperkaya [13] .…”
