Abstract

Determining relationship between soil properties and phosphorus uptake is important to support P fertilizer recommendation. The objective of this research was to determine the relationship between some soil chemical properties and phosphorus uptake of lowland rice on kaolinitic and smectitic soils. Field experiments were conducted in Lampung kaoliniticpaddy soils and East Java smectitic paddy soils with low, medium, and high P content variabilities. The experiments used completely randomized block design with four replications. The treatments consist of five P fertilizer levels that were 0, 23, 46, 69, dan 115 kg P2O5 ha-1, applied as superphosphate (SP-36). In kaolinitic soils, P uptake response with P fertilizer was not significant, whereas in smectitic soils P uptake response was significant. In kaolinitic soils, organic C correlated positively withP uptake of lowland rice, while the correlation of pH, clay content, exchangeable Ca, Fe, and Al were not significant. In smectitic soils, organic C correlated negatively with P uptake of lowland rice, while the correlation of pH, clay content, exchangeable Ca, Fe, and Al were not significant. Thus, increasing organic matter in kaolinic soils will increase P uptake of lowland rice, while in smectitic soils increasing organic matter will decrease P uptake.

Abstract

Abstract. The farmers want to move from green revolution technology to other rice systems because the former is no longer sustainable.The aim of this study was to study soil chemical-physical characteristics and rice productions of three different rice farming systems. This study was carried out in Sambiredjo Sub District, Sragen Regency, arranged in randomized complete block design with three replications and as the treatments was an organic, semi organic and conventional rice system. One kilo gram composites soil samples of 0-20 cm in depth were collected from five random sampling points of every site and taken in March 2017, before soil preparation. Rice biomass productions namely rice grains, rice straw and rice residues were harvested in the end of June 2017.The results indicated that in organic field, the soil chemical-physical fertility was superior to that of in semi organic and conventional and semi organic system was better than conventional in terms of soil pH, organic C and total N, P and K total, soil bulk density, particle density, soil porosity and permeability. Similar finding was observed for rice biomass productions. The rice grains yields were 7.52±0.49, 6.40± 0.10 and 6.07±0.38, rice straw were 9.04±0.61, 8.67±0.58 and 6.87±0.72 and for rice residues were 4.82±0.48, 3.25±0.31 and 3.23±0.35 tons ha-1 season-1 for organic, semi organic and conventional systems, respectively. Compared to the conventional system, the organic increased about 23 %, 31% and 49 % for rice grains, rice straw and rice residues, respectively. Comparing conventional to semi organic, the improvement was 5 %, 26 % and 0.62 % for rice grains, rice straw and rice residues, respectively. This short term research concluded that organic rice farming was superior than both semi organic and conventional systems, but the long term effect need to be further evaluated.Abstrak. Sebagian petani ingin beralih ke budidaya padi organik karena teknologi green revolution yang mengandalkan masukan tinggi dipandang tidak lumintu. Penelitian bertujuan untuk mempelajari sifat fisik dan kimia tanah serta mengetahui hasil padi dari sistem organik, semi organik dan konvensional. Penelitian dilaksanakan di Kecamatan Sambiredjo, Kabupaten Sragen dengan menggunakan rancangan acak kelompok yang diulang tiga kali, dengan perlakuan: budidaya padi organik, semi organik dan konvensional. Sebanyak satu kilo gram contoh tanah komposit dari ketiga sistem pada kedalaman 0-20 cm diambil dari lima titik secara acak, masing-masing sebelum pengolahan tanah pada bulan Maret 2017. Panen brangkasan padi, yang meliputi gabah, jerami dan sisa tanaman (akar dan potongan batang yang tertinggal) dilakukan pada akhir bulan Juni 2017. Hasil percobaan menunjukkan bahwa sifat kimia dan fisik tanah pada sistem organik lebih unggul dibandingkan dengan semi organik dan konvensional meliputi pH tanah, C organic, kandungan N, P dan K total, berat jenis, kepadatan partikel, porositas dan permeabilitas tanah. Selain itu, budidaya semi organik lebih baik dibandingkan dengan konvensional.Hasil gabah kering dari masing masing teknologi tersebut adalah 7,52±0,49; 6,40±0,10 dan 6,07±0,38, jerami sebesar 9,04±0,61, 8,67±0,58 dan 6,87±0,72 dan sisa tanaman seberat 4,82±0,48; 3,25±0,31 dan 3,23±0,35 ton ha-1musim-1pada budidaya padi organik, semi organik dan konvensional. Dibandingkan dengan budidaya konvensional, sistem organik meningkatkan gabah, jerami dan sisa tanaman berturut turut sebesar sebesar 23 %, 31 % dan 49 %. Apabila dibandingkan antara sistem konvensional dengan semi organik, juga terjadi peningkatan sebesar 5 %, 26 % dan 0.62 % untuk gabah, jerami dan sisa tanaman. Penelitian ini menyimpulkan bahwa budidaya padi organik lebih unggul dibandingkan dengan semi organik dan konvensional namun pengaruh jangka Panjang perlu dievaluasi lebih lanjut.

Abstract

The productivity of rainfed rice needs to be increased in order to support the Indonesian Food Security programs, especially rice. Rainfall is one of the main sources of the water availability on the rainfed rice field. This research was conducted from October 2000 to February 2001 at four sites in Central Java Province. The objectives of this research were to study thevariability of water availability that influenced by toposequen’s position and to analyze the rice yields due to treatments on toposequence. This experiment was carried out in the farmers’ field using “Group Balanced Block in Split-Split Plot Design” and Inceptisols soil order. Mainplots were the four positions in toposequence (top, upper middle, lower middle, and bottom), and the four villages were used as replication. The sub-plot wastreatments group and sub-sub-plot consists of group-1: farmer’s practice and without weeding; group-2: farmer’s practice without fertilizer and added recommended fertilizer. The research showed that rainfall affected the fluctuation of ground water table and standing water periods. The straw and unhulled rice/grain yields at the bottom position was the highest, and was significantly different from the top position of the toposequence, namely 7.1 and 5.6 t ha-1 for straw yield while 5.2 and 4.0 t ha-1 for grainyield. Without weeding, the straw and grain yields decreased by 1.0 t ha-1 (6.1 to 5.1 t ha-1) and 0.8 t ha-1 (4.6 to 3.8 t ha-1). While, without fertilization, the straw and grain yields were produced only 4.4 and 3.8 t ha-1. Straw and grain yields increased up to 7.0 and 5.1 t ha-1, respectively, when recommended fertilizers were applied.

Abstract

Abstrak. Saat ini, tercatat lebih dari 10.000 hektar tanaman kelapa sawit di Indonesia telah dikembangkan pada lahan dengan ketinggian tempat lebih dari 600 m di atas permukaan laut (dpl). Budidaya kelapa sawit di dataran tinggi dihadapkan pada beberapa faktor pembatas seperti rendahnya suhu, tingginya kelembaban dan curah hujan, serta terbatasnya lama penyinaran matahari. Penelitian ini bertujuan untuk mengetahui karakteristik fisiologis tanaman kelapa sawit yang dibudidayakan di empat lokasi dengan ketinggian tempat yang berbeda yaitu: 50, 368, 693, dan >865 m dpl. Penelitian dilakukan pada tanaman kelapa sawit berumur 7-8 tahun. Peubah yang diamati adalah peubah lingkungan/iklim serta performa fisiologis tanaman. Hasil penelitian menunjukkan bahwa karakteristik fisiologis tanaman seperti laju fotosintesis, laju transpirasi, konsentrasi CO2 interseluler, dan dimensi stomata dari tanaman kelapa sawit yang dibudidayakan pada dataran tinggi lebih rendah dibanding proses fisiologis tanaman kelapa sawit yang dibudidayakan pada dataran yang lebih rendah. Akan tetapi tingkat prolin dan aktivitas enzim nitrate reductase yang lebih tinggi dimiliki oleh tanaman yang berada pada dataran tinggi. Penelitian ini menegaskan bahwa karakteristik fisiologi tanaman kelapa sawit yang optimum terdapat pada tanaman yang berada pada dataran dengan ketinggian kurang dari 600 m dpl.Abstract. Nowadays, more than 10,000 hectares of oil palm plantations in Indonesia have been cultivated at the altitude of > 600 m above sea level (asl). The cultivation of oil palm in the higher altitude is subjected to several limiting factors such as low temperature, high humidity and rainfall, and also short daily duration of solar radiation. This study was conducted to evaluate the physiological characteristics of oil palm planted at four altitudes: 50, 368, 693, and 865 m asl. The study was employed for 7-8 years old oil palm. The environmental (climate) and physiological performance variables were measured. The results showed that oil palm planted at the higher altitudes had lower rates of photosynthesis, transpiration, lower intercellular CO2 concentration and lower stomata dimension compared to oil palm cultivated at the lower altitudes. However, the proline level and the activity of nitrate reductase of palm cultivated on the higher altitudes were higher than that of the palm cultivated at the lower altitudes. This research results reconfirm that, the optimum physiological characteristics of oil palm were observed at the altitude of less than 600 m asl.

Abstract

Abstrak. Salah satu upaya untuk mendukung percepatan surplus beras 10 juta ton pada tahun 2014 dan menunjang program swasembada beras nasional melalui peningkatan produksi beras nasional (P2BN) adalah pengembangan padi ke kawasan lahan rawa pasang surut, terutama yang tersebar di pulau Sulawesi, Kalimantan, Papua, dan Sumatera. Untuk itu perlu penelitian yang bertujuan mendapatkan pengelolaan air dan pupuk yang dapat meningkatkan hasil padi. Percobaan lapangan menggunakan Rancangan Split Plot dengan tiga ulangan. Sebagai petak utama adalah pengelolaan air pada sistem: 1) tabat dan 2) pipa. Sedangkan anak petak terdri dari enam kombinasi pemberian pupuk N, P dan K. Hasil penelitian menunjukkan bahwa pengelolaan air pada sistem pipa lebih baik dibandingkan dengan sistem tabat karena kelarutan unsur-unsur N, P, dan K pada air yang keluar dari petak percobaan melalui pipa lebih kecil dibandingkan dengan tabat. Kombinasi takaran pupuk N, P, dan K yang terbaik untuk tanaman padi adalah 200 kg ha-1 urea, 100 kg ha-1 SP-36, dan 100 kg ha-1 KCl.

Abstract

Soil aggregate is soil characteristics which is sensitive to change due to soil tillage. Organic matter practices and soil tillage difference have an important role in determining the quality and quantity of soil aggregate. The objective of this research is to study the quality changes of soil aggregation on Ultisols Jasinga degraded by various soil tillage and organic matter practices. This research was carried out at Jasinga Village, Jasinga Sub District, Bogor District in 2003 planting season (PS). The randomized block design with three replications was used. The Main plot was artificial desurfacing which consisted of three treatments, i.e: non-artificial desurfacing, 5 cm depth of artificial desurfacing, and10 cm depth of artificial desurfacing, whereas sub plot treatments were soil tillage and soil rehabilitation with Mucuna sp. (tillage+Mucuna sp.), no soil tillage and without rehabilitation (no tillage without Mucuna sp.), soil tillage without rehabilitation (tillage without Mucuna sp.), and no soil tillage with rehabilitation (no tillage+Mucuna sp.). The result of this research showed that periodic application of fresh organic matters was able to maintain the quality of macroaggregate on eroded soil (0.36-15.47 cm). Minimum soil tillage application and continuos organic matter practices (>21 t ha-1 year-1) are soil conservation technique that has been able to maintain soil aggregate, even without rehabilitation with Mucuna sp. Various organic matters (Mucuna sp., plant waste, and flemingia) are needed to be applied periodically to maintain the quality of soil aggregate.

Abstract

This study aimed to build a soil hydraulic properties digital database and to identify predictors for soil water retention of Inceptisols using data from developed database. Soil survey reports were compiled and soil hydraulic properties were entried into a spreadsheet. As many as 230 datasets of Inceptisols were extracted from developed database to identify predictors for soil water retention using Banin-Amiel and Stepwise techniques. Currently, the Soil Hydroulic Properties Digital Database strores 832 datasets from Central Kalimantan, East Kalimantan, Flores Island, Lombok Island, and Gorontalo District. The dataset is dominated by Inceptisols and fine soils. The correlation between soil water retention and other soil properties, and the order of predicting effectiveness varies with matrix potensial (pF) which influenced by soil moisture regime and pedogenesis type. Total pores and cation exchange capacity are potential predictors for soil water retention of Inceptisols in addition to particle sizedistribution, organic carbon, and bulk density. The Soil Hydraulic Properties Digital Database stores research results and provides data for any study regarding soil hydraulic properties. The dataset selection for developing pedotransfer function of Inceptisols should consider both soil moisture regime and pedogenesis type.

Abstract

Conversion Conversion and drainage of peat land stimulate soil organic matter (SOM) mineralization, which substantially increase carbon loss from soils. Carbon losses from peat lands are probably a major component in global greenhouse gas emissions. The objectives of this study are to evaluate carbon loss from several land use of peat drained, and to evaluate factors affected carbon loss from several land use on peat drained. The study was conducted in Nanggroe Aceh Darussalam Province from May 2008 until October 2009. Carbon losses were calculated by interpretation data of bulk density (BD), ash content and carbon content from 0-50 cm top soil of peat lands. Peat lands characteristics i.e. physical, chemical and biological properties were investigated by field observation and analysis of peat soil samples on the laboratorium. The results showed that: 1) ash content and bulk density of the peat are related, indicating the partial lost of soil C during decomposition and compaction, 2) an ?internal tracer? estimate of peat C loss yields estimates of CO2 flux up to 56 t CO2-eq ha-1 year-1 for young oil palm, highly correlated with the measured rates of subsidence of the surface, 3) landscape level variation in maximum water table, salinity and Fe of peat are correlated with measured peat carbon loss.
