Food Commodity

Rice is the primary food commodity in Indonesia. To increase the rice production, urea fertilizer has been excessively used, specifically on marginal land. However, it has no desired effect on the plant’s Nitrogen uptake due to volatilization. Previous studies suggest the use of zeolite to be mixed with urea to reduce the volatilization rate. This study aimed to determine the effect of six NP-SR (Nitrogen Phosphorus Slow Release) fertilizer compositions (without NP-SR; 20.69-0; 19.7-5; 17.27-10; 15.9-15; and 18.94-20) on soil chemical properties, nitrogen efficiency, and paddy rice yield on Ultisols at three waterlogging levels (0.5 cm, 3 cm, and 5 cm). The study was an experiment arranged in a Randomized Complete Block Design (RCBD) consisting of two factors, which were waterlogging levels and NP-SR fertilizer compositions. The results showed that waterlogging treatments significantly affected soil chemical properties in the initial vegetative and harvest phases. It can be concluded that the treatment of flooding (up to 3 cm) and fertilizer (NP-SR of 15.90-15) application could significantly reduce the volatilization rate, increase the efficiency of N fertilizer, and increase rice yield.

A field experiment was conducted to find out the effect of different doses of ipil-ipil (Leucaena leucocephala ) (Lam.) de Wit. tree green leaf biomass on rice yield and soil chemical properties. Four different treatments such as T0: Recommended fertilizer dose (Urea 195 kg/ha, TSP 50 kg/ha, MOP 142 kg/ha, Gypsum 75 kg/ha and Zinc Sulphate 4 kg/ha), T1: 5 t/ha, T2: 7.5 t/ha, and T3: 10 t/ha ipil-ipil tree green leaf was used in this study in a Randomized complete block design with three replications. The results showed that the treatment T3 was performed better than recommended fertilizer dose in case all yield contributing characters of rice except grain yield. The highest (5.29 t/ha) rice grain yield was obtained in recommended fertilizer dose followed by 10 t/ha, 7.5 t/ha and 5 t/ha ipil-ipil tree green leaf biomass amendment having 4.80, 3.16 and 2.36 t/ha respectively. The highest grain yield that was obtained from recommended fertilizer dose was 10.21% higher compared to the highest dose (10 t/ha) of ipil-ipil tree green leaf biomass. It was mentioned that among the different doses of ipil-ipil tree green leaf biomass 10 t/ha performed the best over others. The ipil-ipil tree green leaf biomass was also significantly influenced on some essential nutrient status which is very important for rice production. The highest amount of total N, available P, exchangeable K and available S were found in the treatment T3 and the lowest in the treatment T1. Therefore, it can be concluded that the ipil-ipil tree leaf has beneficial effects and could be combined with inorganic fertilizer for sustainable crop yield and maintaining soil fertility.Res.

<p>Utilization of Biochar of Cocoa Shell and Rice Husk to Increase Rice Productivity in Ultisol Lampung. Biochar application as soil amendment is technology for soil and crop productivity improvement in acid soil. The main problem of acid soil including in paddy field is high concentration of Al3+ that inhibit crops growth causing low crop production. The objective of this study was to evaluate the effects of cocoa shell and rice husk biochar on paddy<br />field productivity and soil chemical properties. The study was conducted at Agricultural Research Station of Tamanbogo, East Lampung on June-September 2012 (planting season 1), January-April 2013 (planting season 2) and December 2013-March 2014 (planting season 3). The experimental design was split plot design, which the main plots<br />were two types of biochar (cacao shell and rice husk), the sub plots were biochar rates 0.5 t/ha (control), 5 t/ha and 15 t/ha with five replications. The parameters measured were paddy growth, yield and soil chemical properties (soil pH,C organic, N total, available P, K total, and Al3+ ). The result showed that biochar could affect weight of rice straw and<br />rice yield at the second and third planting season, while biochar rates could affect crop growth and yield of rice at three planting. The effect of cacao shell and rice husk biochar application with the rate of 15 t/ha could up to three planting seasons without any biochar addition in following two consecutives year, whereas addition biochar 5 t/ha was<br />less effective. The cacao shell biochar was more effective in increasing crop growth and yield than rice husk biochar,as seen on dry grain rice yield, i.e. 3.58 t/ha (PS1) and 5.06 t/ha (PS III). During two planting seasons, both biochar at the rate of 15 t/ha were sufficient to improve soil chemical properties. Cacao shell biochar with the rate of 15 t/ha had better effect in improving soil chemical properties significantly in term of soil pH, available P, and total K content and decreasing aluminum content than rice husk biochar especially at second planting season. </p><p>Keywords: lowland, biochar, rice, Ultisol, Lampung</p><p>ABSTRAK</p><p>Aplikasi biochar sebagai pembenah tanah merupakan salah satu teknologi untuk memperbaiki produktivitas tanah dan tanaman pada lahan masam. Permasalahan utama pada lahan masam adalah tingginya konsentrasi Fe3+ yang dapat menghambat pertumbuhan tanaman sehingga menyebabkan rendahnya produksi. Tujuan penelitian ini adalah untuk mempelajari pengaruh pemberian biochar kulit buah kakao dan sekam padi serta takarannya terhadap peningkatan sifat kimia tanah dan produktivitas padi sawah di Ultisol Lampung. Penelitian dilaksanakan pada lahan sawah di Kebun Percobaan Taman Bogo, Lampung selama tiga musim tanam yaitu bulan Juni-September 2012 (musim tanam pertama), bulan Januari-April 2013 (musim tanam kedua) dan Desember 2013 - Maret 2014 (musim tanam ketiga). Percobaan disusun dalam rancangan kelompok petak terpisah, sebagai petak utama terdiri dari biochar kulit buah kakao dan biochar sekam padi, sedangkan sebagai anak petak adalah takaran biochar yaitu tanpa biochar (kontrol 0 t/ha), 5 t/ha dan 15 t/ha, dengan 5 kali ulangan. Parameter yang diamati meliputi pertumbuhan dan hasil padi, sifat kimia tanah (pH, C-organik, N-total, P-tersedia, K-total dan Al3+ ). Hasil penelitian menunjukkan bahwa  jenis biochar hanya berpengaruh nyata terhadap berat jerami kering dan hasil gabah pada musim tanaman kedua dan ketiga, sedangkan takaran biochar berpengaruh nyata terhadap pertumbuhan dan hasil padi pada ke tiga musim tanam. Pengaruh pemberian biochar kulit buah kakao dan sekam padi 15 t/ha mampu bertahan sampai tiga musim tanam dilihat dari pertumbuhan dan hasil padi sawah, sedangkan pemberian biochar 5 t/ha bertahan satu musim saja. Efektivitas biochar kulit buah kakao dalam mendukung pertumbuhan dan hasil tanaman lebih tinggi dibandingkan sekam padi terlihat dari hasil gabah kering panen sebesar 3,58 t/ha (MT II) dan 5,06 t/ha (MT III). Selama dua musim tanam pemberian biochar kulit buah kakao sebanyak 15 t/ha juga mampu meningkatkan pH tanah, P tersedia, dan kandungan K tetapi menurunkan kandungan aluminium melebihi biochar sekam padi terutama pada musim tanam kedua.</p><p>Kata kunci: produktivitas, padi sawah, biochar, Ultisol</p>

Integrated nutrient management, which primarily involves the combined application of organic and inorganic nutrient sources, is one of the simplest approaches to handle declining soil fertility challenges and increase crop productivity and production. Keeping in view this fact, a pot experiment was conducted to evaluate the effects of compost and inorganic nitrogen fertilizer and their mixture on soil properties, growth, and nitrogen uptake of maize on loam and clay textured soils at the Awada Agricultural Research Subcenter. Treatments comprised factorial combinations of five compost rates (0, 5, 10, 15, and 20 t·ha−1) and four rates of inorganic nitrogen fertilizer (0, 46, 92, and 138 kg·N·ha−1) laid out as a completely randomized design with three replications. Results showed that both the main and interaction effects of compost and mineral N fertilizer rates significantly affected the selected soil chemical properties and yield, and nitrogen concentration of maize. There were significant associations between plant parameters and soil nitrogen contents. The addition of 92 kg·ha−1·N + 10 t·ha−1 compost and 46 kg·ha−1·N + 10 t·ha−1 compost was the best treatments for loam and clay textured soils of the study areas, which improved shoot dry matter by 179.5 and 284.5%, compared to the unfertilized pot, respectively. From the results of this experiment, we concluded that the integrated application of compost and mineral nitrogen fertilizer enhanced soil chemical properties and thus improved nitrogen uptake and sustainable production of maize in the study areas.
