Abstract

Pemanfaatan gambut sebagai lahan pertanian dihadapkan dengan masalah kesuburan tanah rendah. Rendahnya kesuburan gambut dicirikan dengan pH masam, kejenuhan basa rendah, kapasitas tukar kation tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian dolomit dan jenis NPK slow release serta interaksi antara dolomit dengan NPK slow release terhadap fisiologi dan pertumbuhan jagung manis pada tanah gambut. Penelitian ini dilaksanakan pada bulan Agustus sampai Oktober 2018 di Unit Pelaksana Teknis Kebun Percobaan dan Laboratorium Tanah Fakultas Pertanian Universitas Riau. Penelitian ini dilaksanakan secara eksperimen dengan menggunakan Rancangan Acak Lengkap (RAL) factorial. Faktor pertama adalah dolomit yang terdiri dari 4 taraf (0 ton.ha-1, 2.5 ton.ha-1, 5 ton.ha-1, dan 7.5 ton.ha-1). Faktor kedua adalah NPK slow release yang terdiri dari 4 taraf (NPK mutiara tunggal, NPK 13:6:27:4+0,65B Mahkota B, NPK 13:6:27:4+0,65B Compound Hi-Kay Plus dan NPK 13:8:27:4 MgO Ztick). Hasil penelitian menunjukkan bahwa pemberian dolomit dan NPK slow release dapat meningkatkan fisiologi seperti kandungan klorofil dan pertumbuhan tanaman jagung manis yaitu tinggi tanaman, jumlah daun, volume akar, berat kering tanaman dan laju pertumbuhan tanaman. Interaksi antara dolomit 23.55 g per tabung dengan pupuk 30.25 N, 3.72 P, 12.56 g per tabung (NPK Ztick) slow release merupakan interaksi terbaik yang mampu meningkatan laju pertumbuhan tanaman 6.65 g/hari.

Abstract

Utilization of peat as agricultural land faced the problem of low soil fertility. Low soil fertility made nitrogen being leached easily. One solution to overcome Nitrogen leaching and efficiency fertilizer raising used dolomite and slow decompose fertilizers. This study aims to determine the effect of dolomite on Nitrogen element leaching in several types of NPK slow decompose applied for corn cultivation in peatland and determine the best dolomite dosage and NPK slow decompose with minimum Nitrogen leaching to optimum sweet corn plant growth in peatland. This research was conducted from August to October 2018 in the Experimental Garden Technical Implementation Unit and Soil Laboratory, Faculty of Agriculture, University of Riau. This research used experimentally and completely randomized design (CRD) factorial. The first factor is dolomite which consists of 4 levels (0 tons.ha-1, 2.5 tons.ha-1, 5 tons.ha-1, dan 7.5 tons.ha-1). The second is NPK slow decompose which consists of 4 levels (NPK single pearl, NPK 13: 6: 27: 4 + 0,65B Mahkota B, NPK 13: 6: 27: 4 + 0,65B Compound Plus Hi-Kay and NPK 13: 8: 27: 4 MgO Ztick). The results showed the administration of dolomite 23.55 g per tube and NPK slow decomposed could reduce Nitrogen leaching, improve physiology and growth of sweet corn plants. Provision of interaction between dolomite 5 ton.ha-1 with NPK slow decomposition (30.25 N, 3.72 P, 12.56 g per tube) produces the best interaction that can reduce the proportion of Nitrogen leaching and it can affects the increasing of plant growth.

Abstract

Macrofauna data on post-fire peat soils have been documented in many literatures, but assessments of soil macrofauna recovery in peatlands after one and a half years after fires are scarce. The aim of this study was to evaluate the recovery of soil macrofauna in peatlands after one and a half years after fires. This research was conducted on peat land in PT.SSS Kuala Panduk Teluk Meranti District, Pelalawan Regency. This research was conducted by survey method. Determination of the location using the purposive sampling method, especially on peatlands after one and a half years after the fire and unburned peatlands. Based on peatland cover, 6 samples were taken, and 6 samples were taken from unburned peatland. Determination of the sampling point using a systematic method. Macrofauna observations included number of families, number of individuals, population density, and diversity index. The study of macrofauna recovery was carried out by t-test on macrofauna data on peatland fires and unburned peatlands. The results shown in peatlands after a year and a half of fires are macrofauna recovery.

Abstract

The growth of oil palm plants, such as height, additional fronds, and stem diameter, depends on the soil condition and its physical properties. Good soil physical properties will support the growth of oil palm plants. On marginal lands such as ex-mining land and sub-soil soil that has poor soil physical properties, improvements must be made. Thus, palm oil cultivation on ex-mining land or subsoil land can grow well. This research aims to study solid application to various soil conditions to improve the growth and physical properties of oil palm plants. The land applied by solid is an ex-mining land subsoil land. Meanwhile, the land with flat topography has not been degraded as a control. The data analysis carried out is an orthogonal contrast test, between control with solid application and without solid application, between solid application with without solid, between among solid application (ex-mining and subsoil land), between among without solid application (ex-mining and subsoil land). The research result shows that soil physical properties and plant growth applied with solid are better than without solid, lower bulk density value, higher total pore space and water holding capacity, taller plant growth, higher palm branches quantity, larger stem diameter. Solid application in ex-mining is lower than solid application on sub-soil, with lower water holding capacity value and lesser palm fronds addition. Without solid application on ex-mining sites, the results are worse than no solid application on sub-soil, with lower water holding capacity and lower plant height. Control is better than solid and without solid applications, higher plants, higher addition of frond quantity, and larger stem diameter.

Abstract

This study aims to determine the response of water spinach to rice straw and NPK compost, and looking for a best combination of rice straw and NPK compost that provides the best growth and production of water spinach. This research carried out in the Faculty of Agriculture Experimental Station, Riau University, starting from February 2018 until May 2018. This study used a Randomized Block Design with 2 factors and 3 replications. The first factor was rice straw compost (0, 7 and 14 ton.ha-1) and second factorI namely NPK fertilizer (0, 100 and 200 kg.ha-1). The parameters observed were plant height, leaf number, leaf area, fresh weight, root shot ratio and plant dry weight. Data were analyzed using anova and with HSD 5%. Increasing the dosage of rice straw compost significantly increased plant height, leaf number, leaf area, fresh weight, root to shoot ratio and dry weight of land water spinach. The interaction of giving rice straw compost and NPK fertilizer significantly increased plant height, leaf number, leaf area, fresh weight, and dry weight except the root canopy ratio of land water spinach. The interaction of rice straw compost 14 ton. ha-1 in NPK 200 kg. ha-1 was the best dose to increase plant height, leaf number, leaf area, fresh weight, root canopy ratio and dry weight of land water spinach. Keywords: Ipomoea reptans Poir, rice straw compost and NPK fertilizer
