Abstract Fertilizer is considered to be one of the important factors in increasing shallot production. However, this must be followed by proper fertilization management to meet the nutrient requirements of the plant. This research was conducted with the aim of dertermining the correct dosage of NPK 16:16:16 based on ammonium nitrate in shallot plants. The assessment was carried out in October-December 2018. The research was carried out at one of the centers of shallot development, specificallly in Batu Rampung Hamlet, Tanete Village, Angeraja Sub-District, Enrekang Regency, South Sulawesi. A randomized block design (RBD) was used in this research, accompanied by three replications and eight treatments: P1 = NPK Nitrate 16-16-16 450 kg/ha + Urea 150 kg/ha + ZA 300 kg/ha; P2 = NPK Nitrate 16-16-16 400 kg/ha + Urea 150 kg/ha + ZA 300 kg/ha; P3 = NPK Nitrate 16-16-16 350 kg/ha + Urea 150 kg/ha + ZA 300 kg/ha; P4 = NPK Nitrate 16-16-16 900 kg/ha; P5 = NPK Nitrate 16-16-16 800 kg/ha; P6 = NPK Nitrate 16-16-16 700 kg/ha; P7 = Urea 200 kg/ha + ZA 400 kg/ha + KCL 100 kg/ha; P8 = NPK Phonska 645 kg/ha + Urea 645 kg/ha + SP36 645 kg/ha. The results showed that NPK Nitrate Fertilization 16:16:16 at a dose of 700- 900 kg/ha indicated a fairly high growth and production (14.5-16.3 t/ha). The results obtained were not significantly different from the high-dose fertilization used by farmers (17.2 t/ha), and higher than the single dose based on the recommendation (12.8 t/ha).

Mycorrhizal Inoculation

The efforts to improve the productivity of soybean can be done through technological innovation by the provision of chemical fertilizers and mycorrhizae. This study were aimed to obtain information on the effect of a single fertilizer, which can provide the same or higher level of soybean crops if compared with those compound fertilizers, as well as to find out the effect of mycorrhizae to the improvement of efficiency in the use of inorganic fertilizers. It is expected that the mycorrhizae inoculation can reduce single fertilizer’s dose to the level equivalent to the compound fertilizer given by farmers. The study was conducted in Bleberan Village, Playen Subdistrict, Gunung Kidul Regency, Yogyakarta from February to May 2015. It was conducted by using a two-factors factorial design arranged in a randomized block design with three replications. The first factor was inorganic fertilizer (N, P2O5 and K2O), consisting of 5 levels, i.e. without fertilizer (0-0-0 kg/ ha), Phonska fertilizer (45-45-45 kg/ha), single fertilizer (45 -45-45 kg/ha), a low single fertilizer (23-36-30 kg/ha) and high single fertilizer (23-108-90 kg/ha). The second factor was mycorrhizal inoculation, consisting of three levels, i.e. without mycorrhizae (0 g), medium dose (2.5 g) and high dose (5 g). Data were analyzed using Analysis of Variance (ANOVA) at a significance level of 5%. If there was a significant difference, analysis was followed by Duncan Multiple Range Test with a significance level of 5%. The relationship between variables observed was examined by a correlation analysis. The results showed that there was no interaction between inorganic fertilizer and mycorrhizal application. The dose of single fertilizer which was equivalent to the dose of compound fertilizer given to soybean could increase crops by 1.37 t/ha compared with plants treated with a compound fertilizer 1.13 t/ha. The results of correlation analysis among parameters showed that there were correlations between the grain crops and height (r = 0.506**), stem diameter (r = 0.303*), and the number of pods per plant (r = 0.313*).

Penelitian ini dilakukan untuk mendapatkan informasi tentang kebutuhan optimum kadar protein dan lemak pakan terhadap pertumbuhan dan komposisi badan ikan kerapu macan ukuran konsumsi. Sembilan pakan uji dibuat dalam bentuk moist pelet dengan tiga dosis protein (46%, 49%, dan 52%) dan tiga dosis lemak (9%, 11%, dan 13%). Ikan uji dipelihara dalam 27 keramba jaring apung ukuran 1 m x 1 m x 2 m selama 140 hari, diberi pakan uji secara satiasi dua kali sehari dan diset dalam rancangan acak kelompok pola faktorial berdasarkan kelompok ukuran bobot awal ikan yaitu (i) 122,0±4,2 g; (ii) 144,0±7,1 g; dan (iii) 172,9±10,5 g. Hasil penelitian menunjukkan bahwa laju pertumbuhan spesifik dan sintasan ikan relatif sama (>0,05) di antara perlakuan. Efisiensi pakan cenderung meningkat dengan meningkatnya kadar protein dan lemak pakan. Tingkat efisiensi pemanfaatan protein cenderung menurun dengan meningkatnya kadar protein pakan, tetapi meningkat dengan meningkatnya kadar lemak pakan. Hasil analisis proksimat badan ikan menunjukkan bahwa kadar bahan kering dan lemak ikan relatif tidak dipengaruhi (P>0,05) oleh peningkatan kadar protein pakan, namun kadar bahan kering dan lemak ikan tersebut sedikit naik dengan meningkatnya kadar lemak pakan. Kadar protein dan abu ikan relatif tidak dipengaruhi oleh perubahan kadar protein dan lemak pakan. Berdasarkan hasil penelitian ini tampak bahwa pakan dengan kadar protein 49% dan lemak sekitar 11% mampu memberikan pertumbuhan dan komposisi badan ikan kerapu macan yang baik.This experiment was conducted to investigate the optimum dietary protein and lipid level for growth and body composition of tiger grouper. Nine dietary experiments were formulated to moist pellet contain three levels of protein (46%, 49%, and 52%) and three levels of lipid (9%, 11%, and 13%). The fish were fed twice daily to satiation for 140 days in twenty seven net cages of 1 m x 1 m x 2 m, were set up factorial randomized block design based on fish size group i.e. (i) 122.0±4.2 g, (ii) 144.0±7.1 g, and (iii) 172.9±10.5 g. The results shown that specific growth rate and survival rate were not significant different (P>0.05) for all treatments. Feed efficiency increased when protein and lipid content increased. Protein efficiency decreased when protein diets increased and increased when lipid diets increased. No interaction occurred between protein and lipid content to all observable biological variables. Dry matter and lipid content of test fish were not affected by protein diets increase but by lipid diet content. Protein and ash of test fish were not affected by either protein or lipid contained in diet. To assure high growth rates and high quality of fish product, it is suggested to feed tiger grouper with diet containing 49% protein and 11% lipid.

ABSTRACTApplication of liquid organic fertilizer formula plus on degraded soil to improve the productivity of the land and chili (Capsicum annuum L.) productionSoil exploitation in large numbers occurred in the District Wanaraja of Garut Regency. Excavation of soil more than 2 meters from the top layer for the manufacture of red bricks has exceeded the ability of the soil to re-establish its structure. So that the soils, which were agricultural lands, can be classified as degraded soils with less fertility and chemical properties. Lans reuse for agriculture requires adequate recovery and fertilizer input. This study aimed to determine the formula of LOF (liquid organic fertilizer) plus used with NPK compound fertilizer on degraded soil to improve the soil productivity. The design used was a Simple Randomized Block Design (RBD) by 10 combinations of LOF plus treatment with NPK compound fertilizer as follows: A = Control (degraded soil, no fertilizer), B = 0% LOF + 1 NPK, C = 0.25% LOF + 1 NPK, D = 0.50% LOF + 1 NPK, E = 0.75% LOF + 1 NPK, F = 1.00 % LOF + 1 NPK, G = 0.5% LOF + 3/4 NPK, H = 0.5% LOF + 1/2 NPK, I = 0.5% LOF + 1/4 NPK, J = 0.5 LOF + 0 NPK, and K = 1 NPK of normal soil that all replicated three times. The results showed that the degraded soil of red bricks required concentration of LOF above 0.5% to 1% when applied with 1 dose of standard NPK. It is able to balance the uptake of nutrients P, Ca, and B and percentage of fruitset in chili commodities equivalent to normal soil.Keywords: Chilli, Liquid Organic Faertilizer (LOF), NPK, Soil degrededABSTRAKEksploitasi tanah dalam jumlah yang besar terjadi di Kecamatan Wanaraja, Kabupaten Garut.

<p>ABSTRACT</p><p>Effective and efficient fertilization is affected by fertilizer dose, and therefore information on the appropriate dose of a single fertilizer for oil palm will be beneficial to increase the efficiency and effectiveness of fertilization in oil palm plantations. The objectives of this research were to study the response patterns and to determine optimum rate of single fertilizer package related to the growth of one year old oil palm trees. The experiment was conducted from March 2013 to February 2014 at IPB-Cargill Teaching and Research Farm of Oil Palm, Jonggol Bogor. The experiment was arranged in randomized block design with one factor and replicated three times. The treatments were four single fertilizer package as followed: control, 300 g urea + 375 g SP-36 + 350 g KCl + 25 g boric acid + 25 g CuSO4.5H2O, 600 g urea + 750 g SP-36 + 700 g KCl + 25 g boric acid + 25 g CuSO4.5H2O, 900 g urea + 1125 g SP-36 + 1050 g KCl + 25 g boric acid + 25 g CuSO4.5H2O per plant. The result showed that application of single fertilizer package significantly increased the growth of young oil palm linearly as shown by plant height, stem girth, leaf area of frond number 9, chlorophyll and P content of the leaves and quadratically on leaf number at the last observation. The optimum rate of single fertilizer for one year old oil palm trees had not been attained at this research because the plant growth response to fertilization was still linear.</p><p>Keywords: inorganic, leaf frond number 9, optimum rate, growth response, stem girth</p>

Thinning is one of silvicultural management actions in maintaining and increasing growth and quality of standing stands. This study aims to determine growth response of selected teak clone to several intensities of thinning and intercropping. The method was a factorial completely randomized block design (RCBD) with thinning intensity (4 levels): 0% (control = A1), 25% (A2), 50% (A3) and 75% (A4) as the main plot, whileintercropping (2 levels), as the sub plot. The results showed that the Current Annual Increment (CAI) of diameter at breast height (CAI DBH), volume/tree (CAI vol/tree) and volume/hectare (CAI vol/ha) of stands gave a significant positive response to thinning intensity treatment. CAI DBH one year after thinning were 0.79 cm, 1.47 cm, and 2.46 cm; increased by 32%, 145% and 310% at the thinning intensity of 25%, 50% and 75% when they compared with the control (0.59 cm). CAI vol/ha of stand in the first year, namely 11.88 m3/ha, 14.04 m3/ha, and 16.78 m3/ha or with an increase of 9%, 29% and 54% respectively at an intensity of 25 %, 50% and 75% compared to the control.
