Abstract

Rice (Oryza sativa) production in Indonesia has declined due to low iron (Fe) availability in alkaline soils, impacting plant growth and yield. Integrating Fe seed coating with sago (Metroxylon sp.) waste organic fertilizer may improve Fe availability and soil quality, offering a potential solution to enhance rice production. Our objective was to examine the effects of Fe seed coating and the incubation of sage waste organic fertilizer on rice growth. The study employed a factorial 2-factor randomized block design. The first factor was the concentration of Fe seed coating, with four levels: 0 g, 55 g with 2.5 g gypsum, 110 g with 5 g gypsum, and 275 g with 12.5 g gypsum. The second factor was the incubation time of organic fertilizer, with four durations: 0 weeks, 3 weeks, 4 weeks, and 5 weeks. The interaction between Fe seed coating and sago waste organic fertilizer incubation significantly impacted plant height (153.33 cm), leaf color chart scale (4), chlorophyll a (254.73 μmol.m-2), chlorophyll b (96.90 μmol.m-2), with the most notable effects observed at a Fe seed coating concentration of 275 g with 12.5 g of gypsum and a 5-week incubation period. The application of Fe seed coating at a concentration of 275 g with 12.5 gypsum, combined with a 5-week of sago waste organic fertilizer, effectively enhances plant height, chlorophyll a, chlorophyll b, and the leaf color chart scales.

Abstract

Lahan yang sesuai untuk usaha pertanian adalah lahan yang mempunyai kecocokan antara potensi lahandengan syarat tumbuh optimal suatu jenis tanaman pertanian. Penelitian ini dilakukan untuk menentukandan memetakan kelas kesesuaian lahan sayur-sayuran (hortikultura) khususnya tanaman kentang, tomat,dan kubis di Desa Tonasa Kecamatan Tombolo Pao. Penelitian ini menggunakan metode kualitatifdengan menggunakan pendekatan faktor pembatas sederhana. Pengambilan sampel dilakukan secarapurposive sampling berdasarkan peta unit lahan yang terdiri dari empat unit lahan, pada sistem lahan Barong Tongkok (BTK) dan Tanggamus (TGM). Kriteria kesesuaian lahan yang digunakan adalah kriteria menurut Djaenuddin et al. (2011). Penelitian ini menunjukkan bahwa kelas kesesuaian lahan aktual di lokasi penelitian untuk tanaman kentang tergolong sesuai marginal (S3) seluas 2.037 Ha (100%) dengan faktor pembatas retensi hara yaitu pH. Untuk tanaman tomat sebagian tergolong cukup sesuai (S2) seluas 1.778 Ha (87,29%) dengan faktor pembatas ketersediaan air yaitu curah hujan dan kelembaban; retensi hara yaitu kejenuhan basa dan pH; bahaya erosi yaitu lereng serta sebagian tergolong S3 seluas 259 Ha (12,71%) dengan faktor pembatas retensi hara yaitu pH. Untuk tanaman kubis tergolong S3 seluas 2.037 Ha (100 %) dengan faktor pembatas retensi hara yaitu kejenuhan basa dan pH. Desa Tonasa Kecamatan Tombolo Pao memiliki potensi untuk pengembangan tanaman hortikultura yang ditunjukkan dengan hasil analisis kesesuaian lahan aktual untuk tanaman kentang (S3), tomat (S2 dan S3), dan kubis (S3). Kelas kesesuaian lahan potensial tergolong S2 untuk tanaman kentang, tomat, dan kubis dengan faktor pembatas kelembaban.

Abstract

Using biological agent microorganisms such as Arbuscular Vesicular Mycorrhiza (AVM) is needed to improve post-mining soil fertility. This research aimed to explore and identify morpho species of AVM in the post-nickel mining areas Soil samples were taken from the tree rhizosphere at each representative point. The soil samples have been isolated using Brundrett's method of wet sieving and decanting; AVM spore density is determined for each 20 g soil sample; and spores are grouped based on morphological traits up to the morphogenic stage of the species. The results showed that there are four mycorrhizal species found in the rhizosphere of plants in the nickel post-mining soil of PT Vale Indonesia Tbk., namely Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp. Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp obtained 18, 8, 8, and 7 morpho species, respectively. The highest spore density is 34 spores of Gigaspora sp4 found in the rhizosphere of Casuarina rumphiana, 57 spores of Acaulospora sp1 in the rhizosphere of Macaranga gigantea, two spores of Glomus sp1, sp2, and sp6 each as many as two spores per 20 g of soil in rhizosphere of Enterolobium cyclocarpum, Dillenia serrata, Maesopsis eminii, 11 spores of Scutellospora sp6 in the Shizigium sp rhizosphere. One finding revealed that Gigaspora and Acaulospora predominated in the rhizosphere over other mycorrhizas. The results of this AVM identification will be the basis for the mass propagation of local AVM for broader use in the post-nickel mining land area in Sorowako. Widespread use of AVM is a form of post-nickel mining land management based on local resource potential, particularly the dominant trees rhizosphere and the most commonly found AVM types. This proves that AVM can colonize plant roots in this nickel post-mining soil and potentially be mass-propagated, especially species.
