<p>ABSTRAK<br />Kencur (Kaempferia galanga) banyak dimanfaatkan oleh rumah<br />tangga, industri obat maupun makanan serta minuman dan industri rokok<br />kretek. Peningkatan pemakaian simplisia kencur dalam berbagai industri di<br />dalam negeri akan meningkatkan konsumsi simplisia ini, sehingga upaya<br />peningkatan produksi masih perlu dilakukan melalui budidaya, di<br />antaranya dengan penggunaan varietas unggul yang didukung dengan<br />pemupukan yang optimal. Di dalam penelitian ini dikaji respon lima<br />nomor unggul kencur terhadap paket pemupukan organik dan anorganik<br />pada tanah latosol di dataran rendah, Cileungsi, Bogor, Jawa Barat.<br />Penelitian dilaksanakan mulai bulan Oktober 2003 sampai Agustus 2004,<br />dengan RAK dalam pola faktorial. Faktor I nomor unggul kencur (V1, V2,<br />V3, V4 dan V5) dan faktor II paket pemupukan (6 paket), diulang 2 kali.<br />Jarak tanam yang digunakan 20 x 20 cm, ukuran petak 4 x 1,2 m. Hasil<br />penelitian menunjukkan, empat nomor unggul kencur (V1, V3, V4, V5),<br />dari lima nomor yang diuji, mempunyai kemampuan untuk menghasilkan<br />rimpang segar dan kering yang sama, dengan kisaran bobot rimpang segar<br />62,27-70,22 g/tanaman dan kisaran bobot rimpang kering 16,95-19,33 g/<br />tanaman. Paket pemupukan yang dianjurkan untuk semua nomor yang<br />diuji adalah pupuk kandang 20 ton/ha + urea 250 kg/ha + SP36 200 kg/ha<br />+ KCl 200 kg/ha, atau pemupukan organik dengan pupuk kandang kerbau<br />40 ton/ha. Respon lima nomor unggul kencur terhadap aplikasi paket<br />pemupukan memberikan mutu dengan hasil yang berbeda, yaitu kadar<br />minyak atsiri V3 (2,03%) tergolong mutu I, sedangkan empat nomor<br />lainnya tergolong mutu II (1,08 -1,97%), dengan hasil minyak atsiri 0,325<br />– 0,466 ml/tanaman. Serapan hara lima nomor unggul kencur terhadap<br />paket teknologi yang diuji memperlihatkan, serapan hara N berkisar antara<br />149,60 – 415,60 mg/tanaman, hara P 41,50 – 112,50 mg/tanaman, hara K<br />236,10 – 571,70 mg/tanaman.<br />Kata kunci : Kencur, Kaempferia galanga, varietas unggul, pemupukan,<br />serapan hara, produksi, mutu</p><p><br />ABSTRACT<br />Response of five galanga promising lines to fertilization<br />India galanga (Kaempferia galanga) is commonly used for<br />household consumption, medicines, food and drink supplement industries<br />as well as cigarette sauce. Increase in demand of this commodity for<br />domestic industries will raise the consumption of symplicia. Therefore,<br />effort in increasing yield of the plant through cultivation technique<br />improvement, i.e. application of superior variety and fertilization, is worth<br />to be accomplished. In this experiment five Galanga promising lines of<br />India galanga were subjected to organic and inorganic fertilizations at<br />low land latosol soil, Cileungsi, Bogor, West Java. Experiment was carried<br />out from October 2003 – August 2004 and arranged in randomized block<br />in factorial design, with two replications. First factor is the promising lines<br />(V1, V2, V3, V4 and V5); factor II is fertilization packages (6 packages).<br />Plot size of 4 x 1.2 m and plant spacing of 20 x 20 cm, were applied. The<br />results showed that four of five tested promising lines yielded the same<br />results of fresh and dry weight of rhizomes ranged from 62.27-70.22<br />g/plant, and the dry weight was 16.95-19.33 g/plant respectively.<br />Fertilization packages of dung manure 20 t/ha + urea 250 kg/ha + SP36<br />200 kg/ha + KCl 200 kg/ha, or organic fertilizer by using dung manure 40<br />ton/ha, are recommended. Application of fertilization package resulted in<br />different response to the plant for their qualities. The essential oil content<br />of promising lines V3 belongs to the first grade of quality (2.03%), while<br />the others are the second one (1.08-1.97%), with the yield of essential oil<br />ranged from 0.325 – 0.466 ml/plant. The nutrients uptake of the promising<br />lines to the applied technology package were 149.60 – 415.60 mg/plant of<br />N, 41.50 – 112.50 mg/plant of P, and 236.10 – 571.70 mg/plant of K<br />nutrients.<br />Key words: Kaempferia galanga , superior variety, fertilization, nutrient<br />up take, yield, quality</p>

Field experiment was conducted at the research Farm of JNKVV, Jabalpur (M.P) during the Kharif season of 2018 with three main treatments as single year application, alternate and each year zinc addition and five levels of Zn (0, 2.5, 5, 7.5 and 10 kg ha-1 as sub treatments in a split plot design. Results revealed that alternate year Zn application increased seed yield by 1.48 t ha-1 over single year. The difference recorded in between alternate year and single year Zn application was 0.33 t ha-1. Treatment 5.0 kg Zn ha-1 had significantly increased seed yield by 1.43 t ha-1 over control. The difference recorded in between 5.0 kg Zn ha-1 and in control Zn application was 0.38 t ha-1. The each year Zn application and 10 kg Zn ha-1 gave the highest protein (40.30%) and oil content (20.17%) in seed. Results explained that the higher release of Zn pools were observed with the each year Zn application and 10 kg Zn ha-1. The order of prevalence of Water soluble and exchangeable-Zn< Complexed-Zn<Amorphous Sesquioxide < Crystalline Sesquioxide bound-Zn< Residual-Zn.

An experiment was done to evaluate the effect of different levels of nitrogen, phosphorus and potassium fertilization on the yield, quality and foliar nutrient concentration of 'Orlando' tángelo in a Corozaf clay soil. Nitrogen levels evaluated were 0,85.2,170 and 341 kg/ha. Levels of phosphorus evaluated were 0,12.4, 24.8 and 49.6 kg/ha; and potassium levels were 0, 47.8, 94.6 and 188 kg/ha. A significant linear response was found between the nitrogen application and the cumulative production of fruits per tree. High application of nitrogen was related to high cumulative production. No significant relationship was found between the phosphorus and potassium levels and the cumulative production. The application of different levels of nitrogen, phosphorus, and potassium had no effect on the average fruit weight and the quality of fruits in terms of pH, brix, acidity and brix/acidity rate. The different levels of nitrogen significantly affected the foliar nutrient concentration of nitrogen, calcium, potassium and phosphorus. Different applications of phosphorus significantly affected the foliar concentrations of calcium and potassium. The levels of potassium had no significant effect on the foliar concentrations of the different elements evaluated.

This study was carried out to evaluate the effect of mycorrhizal inoculation on the growth and nutrients uptake of maize planted in crude oil-contaminated soil. About 10 kg sterilized topsoil was contaminated with Bonny light crude oil (BLCO) at different concentrations: 0, 200, 300, and 500 ml/pot. Maize was sown at three seeds per pot and later thinned to two stands per pot after two weeks. Inoculation in treatments containing AM consisted of 20 g of Glomus clarum. Data on residual TPH content of the soil, plant height, number of leaves, fresh and dry weights, and nutrients uptake were collected at 4, 8, and 12 weeks after sowing (WAS). The 2 x 4 factorial experiment was laid in a completely randomized design and replicated 3 times. The results obtained indicated that AM inoculated maize had higher and significantly (p˂0.05) nitrogen, phosphorus, potassium, calcium, plant height, number of leaves, fresh and dry weights. Significantly (p˂0.05) lower residual TPH content was recorded with treatments inoculated with AM fungi compared to non-AM fungi inoculated treatments. AM colonization resulted in enhanced nutrients uptake thus, improving the physiological parameters of the test crop.

A 2-yr field experiment was conducted to determine the influence of supplemental N-P-K foliar fertilizers (9-8-7 or 16-2-3) applied during flowering, fruit enlargement and/or flower initiation on yield, quality, and nutrition of Earliglow strawberries (Fragaria × ananassa Duch.). All plots received soil applied fertilizer at planting and at renovation according to soil test recommendations. Foliar fertilizers did not significantly increase total yield at any of the rates or times of application employed. Average yields the first year were 1.5 times greater than those the second year, regardless of whether foliar fertilizers were applied. Treatments did not significantly affect mean berry weight or percent soluble solids. Concentrations of N and P in recently matured leaves sampled during harvest were not significantly affected by foliar treatments, but K level was increased in the second year of the study by some foliar treatments.Key words: Fragaria spp., foliar nutrient sprays, nitrogen, phosphorus, potassium, strawberry

A study was carried out over a 5-yr period on the influence of different forms of N and P on agronomic and chemical characteristics of cigar tobacco. Results showed that sulphur-coated urea significantly increased yield and gross return when compared with urea alone, but not when compared with ammonium nitrate or ammonium sulphate. Regular superphosphate (0–20–0) was shown to be superior to concentrated superphosphate (0–46–0) for yield, quality index and gross return. Key words: cigar tobacco, nitrogen, phosphorus
