Abstract

Effects of Ameliorant and Mycorrhiza on Soil Phosphate Availability, Phosphorus Uptake, Growth, and yield of Corn (Zea mays L.) in Andisol.Abstract. Andisol is soil with a very high P adsorption, whereas available P is very low. As low P availability, P becomes limiting to plant growth. This study was aimed at determining the effect of ameliorant and mycorrhiza application on availability of phosphate and growth and phosphorus uptake of corn in Andisol. Soil samples of Andisol were taken from Tunyang Village, Timang Gajah Sub District at 0-20 cm depth of typic hapludand. The experiment was carried out in pots and arranged in a randomized complete block design (RCBD) 4x2 factorial with 3 replications. The first factor was types of ameliorant, consisting of 4 levels, i.e. without ameliorant, manure, rice straw and Gliciridia leaves, each 20 t ha-1 or equivalent to 111 g per polybag. The second factor was mycorrhiza with 2 levels, i.e. without mycorrhiza and mycorrhiza 10 g per polybag. Results showed that various types of ameliorants affected soil pH, total P, available P (Bray 1), and index of soil P availability and improved growth, phosphorus uptake, and yield of corn. Mycorrhiza affected soil pH, plant height at 15 and 30 days after planting and mycorrhizal root infection, but did not affect soil P availability and yield of corn. There was no interaction between ameliorant and mycorrhiza. Types of ameliorant providing the best P availability and yield of corn were manure and Gliciridia leaves at dose of 20 t ha-1.Abstrak. Andisol merupakan tanah yang mempunyai jerapan P yang sangat tinggi sedangkan P tersedia sangat rendah. Ketersediaan P relatif rendah, P menjadi pembatas bagi pertumbuhan tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh amelioran dan mikoriza terhadap ketersediaan fosfat dan pertumbuhan serta serapan fosfor tanaman jagung (Zea mays L.) pada Andisol. Sampel tanah ordo Andisol dari Desa Tunyang Kecamatan Timang Gajah Kabupaten Bener Meriah pada kedalaman 0 – 20 cm dari jenis typic hapludand. Penelitian ini dilaksanakan dengan menggunakan percobaan pot yang ditata menurut rancangan acak kelompok (RAK) faktorial 4x2 dengan 3 ulangan. Faktor pertama adalah jenis amelioran yang terdiri atas 4 taraf (jenis) yaitu tanpa amelioran, pemberian pupuk kandang, jerami padi dan daun gamal masing-masing sebanyak 20 ton ha-1 atau setara 111 g per polibag. Faktor kedua adalah aplikasi mikoriza dengan 2 taraf yaitu tanpa mikoriza dan pemberian mikoriza sebanyak 10 g per polibag. Hasil penelitian menunjukkan bahwa pemberian amelioran dari berbagai jenis berpengaruh terhadap pH tanah, P total, P tersedia (Bray 1) dan indek ketersediaan P tanah serta dapat meningkatkan pertumbuhan, serapan fosfor dan hasil tanaman jagung. Pemberian mikoriza berpengaruh terhadap pH tanah, tinggi tanaman 15, 30 HST dan infeksi akar bermikoriza, tetapi tidak berpengaruh terhadap ketesediaan P tanah dan hasil jagung. Tidak ada interaksi antara faktor jenis amelioran dengan faktor pemberian mikoriza. Jenis amelioran yang memberikan pengaruh terbaik terhadap ketersediaan P dan hasil jagung diperoleh pada pemberian pupuk kandang dan daun gamal dengan dosis 20 t ha-1.

Abstract

Abstrak: Untuk mengantisipasi menurunnya luas panen dan produksi jagung di Aceh serta untuk tercapainya swasembada jagung nasional di tahun 2017 pemanfaatan lahan-lahan sub-optimal seperti Ultisol dapat dijadikan alternatif. Namun penanganan khusus perlu dilakukan untuk mengatasi permasalahan-permasalahan yang dapat menghambat pertumbuhan tanaman. Dewasa ini, keinginan yang kuat terhadap pertanian berkelanjutan telah mendorong peningkatan pemanfaatan mikrobia tanah indigenus dan aplikasi bahan organik ke tanah. Penelitian ini bertujuan untuk mengetahui pengaruh fungi mikoriza arbuskula spesifik lokal dan kompos terhadap pertumbuhan jagung pada tanah sub-optimal Ultisol. Rancangan yang digunakan adalah rancangan acak kelompok (RAK) faktorial 3 x 3 dengan 3 ulangan. Faktor yang diuji adalah jenis fungi mikoriza arbuskula (kontrol, Glomus sp. dan Acoulospora sp), dosis kompos (0, 25, dan 50 g pot-1). Peubah yang diamati dalam penelitian ini adalah tinggi tanaman dan jumlah daun pada umur 15, 30, dan 45 hari setelah tanam (HST). Hasil analisis ragam menunjukkan bahwa tidak terjadi pengaruh yang nyata baik secara tunggal maupun interaksi antara pemberian mikoriza asbuskula spesifik lokal dan kompos terhadap tinggi tanaman dan jumlah daun 15, 30 dan 45 hari setelah tanam (HST) pada Ultisol. Abstract: To anticipate the decline in harvested area and production of maize in Aceh as well as to achieve national self-sufficiency in maize in 2017 the use of sub-optimal land as Ultisols can be used as an alternative. However, special care needs to be done to address issues that can inhibit plant growth. Today, a strong desire to sustainable agriculture has prompted increased use of soil microbial indigenus and application of organic material to the soil. This study aims to determine the effect of arbuscular mycorrhizal fungi (AMF) specific local and compost on the growth of maize in sub-optimal soil Ultisols. The design used was a randomized block design (RBD) factorial 3 x 3 with three replications. Factors to be examined is the type of AMF (control, Glomus sp., and Acoulospora sp.), the dose of compost (0, 25, and 50 g pot-1). The parameters observed in this study were plant height and number of leaves at 15, 30, and 45 days after planting (DAP). The results showed that there was no significant effect either singly or interaction between local specific of mycorrhizal asbuscular and compost application on plant height and number of leaves at 15, 30 and 45 DAP.

ABSTRAK. Persoalan utama pada Andisol adalah tingginya kapasitas jerapan P tanah, sehingga tidak tersedia bagi tanaman. Penelitian ini bertujuan untuk mengetahui kemampuan amelioran organik dan mikoriza dalam meningkatkan status P tanah dan hasil jagung. Penelitian ini dilaksanakan dengan menggunakan percobaan pot yang ditata menurut rancangan acak kelompok (RAK) faktorial 4 x 2 dengan 3 ulangan. Faktor pertama adalah pemberian amelioran organik yang terdiri atas 4 taraf (jenis) yaitu tanpa amelioran, pupuk kandang, jerami padi dan daun gamal masing-masing sebanyak 20 ton ha-1 atau setara 111 g per polibag. Faktor kedua adalah aplikasi mikoriza dengan 2 taraf yaitu tanpa mikoriza dan pemberian mikoriza sebanyak 10 g per polibag. Hasil penelitian menunjukkan bahwa pemberian amelioran organik dan mikoriza berpengaruh terhadap pH tanah, P total (ekstrak HCl 25 %), P tersedia (Bray 1) dan indek ketersediaan P tanah serta dapat meningkatkan pertumbuhan dan hasil jagung. Kombinasi perlakuan yang memberikan  pengaruh terbaik terhadap status P dan pertumbuhan serta hasil jagung diperoleh pada pemberian pupuk kandang atau daun gamal yang dikombinasi dengan mikoriza. Organic Ameliorant and Mycorrhiza Increase Soil Phosphate Status and Maize Yield on AndisolABSTRACT. A common problem of Andisol soils is the high capacity for P adsorption, although total P content is relatively high. This characteristic causes inefficient use of P fertiliser, to the point that P deficiency can become a major constraint for crop production. This study aimed to determine the effect of organic ameliorants and mycorrhiza on the status of soil phosphate and yield of maize in Andisol.  The experiment was carried out in pots and arranged in a randomized complete block design (RCBD) 4x2 factorial with 3 replications. The first factor is the addition of organic ameliorant consisting of 4 treatments: without ameliorant, manure, rice straw and Gliciridea leaves. The dosage of each ameliorant is 20 ton ha-1 or equivalent to 111 g per polybag. The second factor is the application of mycorrhiza, consisting of 2 levels, no mycorrhiza and mycorrhiza  at 10 g per polybag. The results showed that the application of organic ameliorant and mycorrhiza  affected soil pH, total P (HCl 25% extractable P), available P (Bray 1), and the P availability index and increased the growth and yield of maize in Andisol. The two treatments that provided the most effect on the status of soil phosphate and plant growth and yield of maize were manure, and Glyricidea leaves, in combination with the addition of mycorrhiza.

Abstract

Lhoknga Sub District was one of regions experiencing earthquake and tsunami disaster occurred on 26 December 2004. The aims of the research were to evaluate soil characteristics, to study land suitability and to propose recommendation of land use and rehabilitation of the tsunami affected agricultural area in Lhoknga Sub District. The result showed that soil textures were varied from very coarse at the area near to the coastline to rather fine at the area far from the coast. The soil structures of topsoil was generally plate and blocky, while that of subsoil was generally massive. The quality of irrigation water in was still suitable for crops, the pH of water was neutral and low in salinity (0,4 mS cm-1). The water quality of wells was high (good) and water quality of drainage and surface water was low (rather bad). Water quality of wells was good enough, indicated by low water salinity (0,26-0,78 mS cm-1) and  low of SAR value. The recommendations for land reclamation were (1) cleaning and repairing of irrigation and drainage channel  (2) leaching of salinity in topsoil from soil profile by flooding method (basin irrigation) or furrow irrigation,  (3) constructing the ditches for cultivation in managing the excess of salinity, (4) establishing ditches for paddy, and (5) removing the sediment above the topsoil.
