Abstract

A pot experiments was conducted in September 2000 until January 2001 at Experimental Station of Faculty ofAgriculture, Udayana University. The experiment was arranged in Completely Randomized Design with treatmentsallocation in factorial with three replications. The treatments were : the first factors consisted of four rates of N,P,Kfertilizers: F1 = 300 kg Urea, 75 kg SP.36, 50 kg KCl ha-1 (1.2 g Urea, 0.3 g SP.36, 0.2 g KCl pot-1) ; F2 = 250 kgUrea, 50 kg SP.36, 25 kg KCl ha-1 (1.0 g Urea, 0.2 g SP.36, 0.1 g KCl pot-1) ; F3 = 200 kg Urea, 25 kg SP.36, 0kg KCl ha-1 (0.8 g Urea, 0.1 g SP.36, 0 g KCl pot-1); F4 = 150 kg Urea, 0 kg SP.36, 0 kg KCl ha-1 (0.6 g Urea, 0 gSP.36, 0 g KCl pot-1). The second factors were three kind of alternative fertilizers : Fr (Floran), Gn (Greener) andDg (Dekorgan) each rate 3 l ha-1 or 1.333 ml pot-1 (concentrations 3 ml l-1 water). The results indicated that theinteractions between fertilizers rates (N,P,K) with kind of alternative fertilizers were not significantly different forall variable observed. The alternative fertilizers not significantly different for all variable too but fertilizers rates(N,P,K) affected the fertile number of rice tillers and highly significantly affected to the available P and K in the soil.The treatment of 250 kg Urea, 50 kg SP.36, 25 kg KCl ha-1 gave the highest fertile tillers (37.00 tillers pot-1) andavailable P in soil (10.18 ppm) but the treatment of 300 kg Urea, 75 kg SP.36, 50 kg KCl was observed the highestavailable K in the soil. The combination treatment of 300 kg Urea, 75 kg SP.36, 50 kg KCl ha-1 with Dekorganproduced the highest rice yield (65.69 g pot-1) or 58.14 % higher than the lowest yield produced by combinationtreatment between 200 kg Urea, 25 kg SP.36, 0 kg KCl ha-1 and Dekorgan.

Abstract

A study of fertilizer formulation (organic + inorganic) to increase the formation of sapwood (gubal) on agarwood plants (Gyrinops versteegii), had done to find the best fertilizer formulation that capable of increase and accelerate either growth and agarwood formation of sapwood on agarwood trees. The first year of study was conducted in Marga Tabanan Village. The field research was Randomized Block Designed (3 groups) with single factor of treatment. The tested treatment were 6 formulation of compound fertilizers and a control (unfertilized treatment). The compound fertlizers consisted of urea, SP-36, KCl, local compost, and dolomite in varying doses. The fertilizer formulations were applied on 21 agarwood trees that previously inoculated with mixed inoculant of Fusarium solani and Rhisopus sp. Three months after inoculation, the data from the following parameters were measured and statistically analyzed: plant height, stem circumference, sapwood weight, resin content and soil chemical properties.The results showed that the tested fertilizer compound had significant effect on plant height, sapwood weight, and resin rendement. No significant effect of fertilizer compound measured on the stem circumference. The highest sapwood weights was obtained on C treatment (14.39 g). The highest resin yield was obtained on B treatment (3.91%) which was relatively the same as that on C treatment (3.85%). Thus, the best fertilizer formulation for either plant growth, agarwood formation or agarwood resin was C treatment (100 g urea + 100 g SP-36 + 100 g KCl) + (7.5 kg compost) + (75 g Dolomite) per tree.

Abstract

This study aim is to determine the effect of the application of Gaharu-C fertilizer formulation of sapwood formed on agarwood plants at three specific locations in Tabanan Regency. This research is a factorial experiment with basic CRD design (completely randomized design). The first factor is location specific consisting of 3 location namely: Pupuan Subdistrict (Pu), Penebel Subdistrict (Pnl), and District of East Selemadeg (Sl). The second factor was the treatment of the Gaharu-C formula fertilizer consisting of 2 ie: 0 (without fertilizer), and C (Gaharu-C fertilizer formulation: 100 g urea + 100 g SP-36 + 100 g KCl) + (7.5 kg compost ) + (75 g dolomite) per tree), each treatment replicated three times. Number of plants used as many as 18 trees. Parameters observed included increased stem diameter, sapwood color, weight of sapwood, resin content and soil chemical properties data. Data analysis used variance analysis and LCD test (?= 0.05). The results showed that specific-location factors had significant effect on increasing stem diameter. However, had no significant effect on the color of sapwood, sapwood weight and resin level of sapwood. The fertilizer factor of Gaharu-C formula has no significant effect on all parameters observed. The highest increase of stem diameter was obtained at Pupuan location (0.40 cm), followed by East Selemadeg (0.32 cm), and the lowest Penebel (0.15 cm). The weight of sapwood and the highest resin content was obtained at the Sl C treatment of 5.34 g and 6.43%. The best application of Gaharu-C fertilizer formulation is in East Selemadeg Subdistrict.

Abstract

Evaluation of Soil Fertility Status with Geographic Information System (GIS) Based on Subak Land at West Denpasar District, Denpasar City, Bali Province This study aims to determine the status of soil fertility, to determine the characteristics of the soil which is a limiting factor to the status of soil fertility, to provide recommendations for land management, and to determine the spatial distribution of soil fertility status on Subak land in West Denpasar District. This research was conducted from December 2020 – March 2021. The method used in this research is the field survey method and soil test with fertility status parameters including Cation Exchange Capacity, Base Saturation, C-Organic, Total phosphate, and Total potassium with reference to the Technical Guidelines for Evaluation of Soil Fertility Bogor Soil Research Center (1995). The results showed that the soil fertility status at the study site was classified as moderate (Subak Pagutan) and high (Subak Semila; Subak Mergaya; Subak Tegal Buah; Subak Tegallantang). Parameters of low total P content in Pagutan Subak and moderate in Semila Subak, Tegal Buah Subak, and Tegallantang Subak as well as moderate K-total content in all subaks are the limiting factors in this fertility status so it is necessary to apply phosphate fertilization in Subak which has a limiting P-total and potassium fertilization as well as adding organic matter to the entire Subak.
