The aim of this study was to evaluate the performance of several Sorghum bicolor cultivars as forage on a dry land with pH of 5.4, N of 0.08%;  C/N of 9%, P of 0.06% and K of 0.01%. Nine cultivars of S. bicolor (Super 1, Super 2, Numbu, Kawali, G2, G5, PAC 537, PAC 593 and PAC 501) were evaluated. Plot size was 16 m2 with space planting of 15 x 75 cm. The experimental design used was randomized block design with three replications.  Parameters observed were plant height, time of flowering, forage production and quality. The result showed that the primary plant growth was not different in all cultivars. In the 65 days old primary plant,  the Super 2, PAC 537 and Kawali had no flower yet. Biomass production varied in primary plant between cultivars of 11.35 - 26.17 kg/16 m2. The highest biomass production was obtained in PAC 537 of 26.17 kg/16 m2 (16.34 t/ha) which were significantly higher than G2 of 11.35 kg/16 m2 (7.09 ton/ha) and was not significantly different with other cultivars. In the 45 days ratoon I, Super 2, G5 and Super 1 showed faster growth. Biomass production increased in the ratoon I around 19.88 kg/16 m2 (12.42 ton/ha). PAC 537 produced the highest biomass of 30.14 kg/16 m2 (18.84 ton/ha) and was not significantly different with other cultivars, except with the G2. Biomass production of ratoon II decreased around 1.83 kg/16 m2 (1.14 t/ha)–4.77 kg/16 m2 (2.98 t/ha) and increased in the ratoon III of 15.72 kg/16 m2 (9.82 t/ha)–26.05 kg/16 m2 (16.28 t/ha). The quality of forage ratoon I was better compared to the primary plant with the lowest one was in ratoon II. It could be concluded that Super 1, Super 2 and PAC 537 cultivars might be recommended as potential forage.

<p>ABSTRAK<br />Tanaman nilam (Pogostemon cablin Benth) sudah lama dibudi-<br />dayakan, namun produktivitas dan mutu minyak yang dihasilkan masih<br />rendah. Rendahnya produktivitas dan mutu minyak tersebut antara lain<br />disebabkan teknologi budidaya yang masih sederhana, dan berkembangnya<br />penyakit, seperti penyakit layu bakteri dan budog, serta hama yang<br />disebabkan oleh nematoda. Penelitian ini bertujuan untuk memperoleh<br />sumber dan dosis kalium yang tepat dalam meningkatkan pertumbuhan<br />dan produksi tanaman nilam. Kegiatan ini merupakan penelitian lapang<br />yang dilakukan di Kuningan, Jawa Barat, dari bulan Januari sampai<br />Desember 2009. Percobaan disusun menggunakan rancangan acak<br />kelompok lengkap, 9 perlakuan dengan 3 ulangan. Perlakuan terdiri atas<br />1) kontrol, 2) dosis KCl 60 kg/ha, 3) dosis KCl 120 kg/ha, 4) dosis KCl<br />180 kg/ha, 5) dosis KCl 240 kg/ha, 6) dosis K 2 SO 4 60 kg/ha, 7) dosis<br />K 2 SO 4 120 kg/ha, 8) dosis K 2 SO 4 180 kg/ha, 9) dosis K 2 SO 4 240 kg/ha.<br />Hasil penelitian menunjukkan bahwa sumber dan dosis kalium secara<br />nyata meningkatkan pertumbuhan dan produksi dibandingkan dengan<br />kontrol. Pertumbuhan tanaman, produksi terna kering, kadar dan produksi<br />minyak nilam terbaik ditunjukkan oleh perlakuan KCl atau K 2 SO 4 dengan<br />dosis 60 kg/ha. Serapan hara N dan P yang tertinggi ditunjukkan oleh<br />perlakuan pemberian 60 kg K 2 SO 4 /ha dan serapan hara K tertinggi pada<br />perlakuan 120 kg KCl/ha.<br />Kata kunci : Pogostemon cablin Benth, kalium, sumber, dosis, produksi,<br />patchouli alkohol</p><p>ABSTRACT<br />Effect of potassium sources on application yield and<br />quality of patchouli<br />Patchouli (Pogostemon cablin Benth) is an aromatic plant that has<br />long been cultivated in Indonesia, however its productivity and quality are<br />still low due to simple cultivation technology, and the development of<br />diseases, such as bacterial wilt disease, budog, and pests caused by<br />nematodes. This study aimed at obtaining sources and dosage of potassium<br />fertilizers to increase plant growth and oil yield of patchouli. The research<br />was conducted in Kuningan, West Java, from May to December 2009 and<br />was arranged using randomized block design, with 9 treatments and 3<br />replicates.

ABSTRAKArbila merupakan legume pakan yang jeraminya merupakan pakan hijauan yang berkualitas bagi ruminansia, dan produksi jeraminya ditentukan oleh kualitas tanah. Level bokashi yang ditambahkan mempengaruhi kualitas tanah, yang tentu berdampak pada produksi jerami arbila. Penelitian bertujuan untuk mengevaluasi produksi jerami arbila pasca panen akibat pemberian level bokashi yang berbeda. Penelitian tersebut telah dilaksanakan selama 5 bulan di Desa Noelbaki. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) dengan 5 perlakuan dan 4 ulangan, terdiri atas P0 = tanpa bokashi (kontrol), P10 = penambahan bokashi 10 ton/ha, P20 = bokashi 20 ton/ha, P30 = bokashi 30 ton/ha, P40 = bokashi 40 ton/ha. Variabel yang diamati adalah  produksi bahan segar jerami (PBSJ) (ton/ha), produksi bahan kering jerami (PBKJ), produksi bahan organik jerami  (PBOJ) arbila. Data yang diperoleh dianalisis varians dan dilanjutkan dengan uji Duncan. Hasil analisis varians menunjukkan bahwa level pemberian pupuk bokashi berpengaruh sangat nyata (P<0,01) terhadap PBSJ arbila serta berpengaruh nyata (P<0,05) terhadap PBKJ dan PBOJ arbila. Berdasarkan hasil penelitian, diketahui rataan PBSJ arbila berkisar 0,46-2,52 ton/ha, PBKJ arbila berkisar 0,07-0,18 ton/ha, dan PBOJ arbila berkisar 0,04-0,16 ton/ha. Hasil uji Duncan menunjukkan bahwa nilai PBSJ, PBKJ dan PBOJ arbila tertinggi terdapat pada perlakuan P40. Disimpulkan bahwa semakin meningkatnya level bokashi Chromolaena dan feses sapi, produksi jerami arbila semakin tinggi. Level bokashi feses sapi dan Chromolaena terbaik adalah 40 ton/ha.Kata kunci: arbila, bokashi, jerami, hijauan ABSTRACTArbila’s straw is a quality feed for ruminants. Production of these straw is determined by soil quality. The level of bokashi added influences the quality of the soil and therefore influences the straw production. This research aimed to evaluate arbila’s straw production post-harvest in different levels of bokashi. This research was carried out for 5 months at Noelbaki. The experimental design used was a randomized block design (RBD) with 5 treatments and 4 replications consisting of P0 = without bokashi (control), P10 = addition of 10 tons of bokashi / ha, P20 = 20 tons of bokashi / ha, P30 = 30 tons of bokashi / ha, P40 = bokashi 40 tons / ha. The observed variables were the straw fresh weight production (SFW) (tons/ha), straw dry matter production (SDM) (tons/ha), straw organik matter production (SOM) (tons/ha). Data were analyzed for variance and continued with Duncan test. Analysis of variance showed that the level of bokashi fertilizer had a very significant effect (P <0.01) on SFW and significantly affected (P <0.05) SDM and SOM. The average SFW in this study ranged from 0.46 to 2.52 tons/ha, HDM ranges from 0.07 to 0.18 tons/ha, and SOM ranges from 0.04 to 0.16 tons/ha. Duncan's test shows that the highest SFW, SDM and SOM are found in P40. It was concluded that arbila’s straw production increases with the level of Chromolaena and cattle manure bokashi added. Highest production was shown in group with 40 ton/ha bokashi.Keywords: bokashi, forage, Phaseolus lunatus L, straw

High ammonia (NH4+) concentration can exert stress on many plants, which causes nutritional disorders and reduction on plant growth. However, depending on the intensity of the stress, it may be attenuated by silicon. In this work, the response of impact of cations and silicon accumulations and plant growth in cultivated papaya plants was investigated under different toxic ammonia concentrations regardless of the presence of silicon (Si). The experiment was conducted at the Universidade Estadual Paulista (UNESP) with papaya seedlings, variety ‘Grupo Formosa’ (Calimosa híbrida 01), grown in a glass greenhouse, in 1.7 dm3pots filled with pine and coconut fiber-based substrate. The experimental design was a randomized block design, in a 5 × 2 factorial arrangement. There were five ammonium concentrations: 10, 20, 40, 80, and 100 mmol L-1that were delivered via nutrient solution, in the absence and presence of Si (2 mmol L-1), with five replicates. After 31 days of growth, the cations and silicon accumulations in the shoot, plant height, stem diameter, root, and shoot dry matter were evaluated. Results revealed that increased ammonia concentration showed toxicity in papaya plants and stronger reductions in Ca, Mg, K and Si accumulations, plant heights, stem diameters, and root and shoot dry matter production, even when silicon was present and with greater effects on the shoot dry matter (87 %) than that of the roots (13 %).

ABSTRACT The use of mycorrhiza is a promising biotechnology that makes coffee cultivation sustainable in the use of fertilizers. In this sense, plant growth and phosphorus contents were assessed in coffee inoculated with Rhizophagus clarus, Claroideoglomus etunicatum and Dentiscutata heterogama in soil fertilized with 0, 0.74, 1.48 and 2.96 g P2O5 kg-1. The experimental design was a randomized block design in a 4 × 4 factorial scheme with four replications. The mycorrhizal seedlings were previously produced and later transplanted to pots, simulating the field planting. The assessments were performed 150 days after transplanting. All variables were influenced by inoculation, but the effects were dependent on P doses. P doses higher than 50% of the recommended dose (0.74 g P2O5 kg-1) decreased the benefit of mycorrhiza. The fungi Rhizophagus clarus and Claroideoglomus etunicatum promoted a higher growth of coffee plants when compared to non-inoculated plants in non-sterilized soils and with a reduction in the applied P.

The objective of this work was to compare forage production and quality of thorny and thornless "jurema-preta" (Mimosa tenuiflora (Willd.) Poiret) in a dense planted stand, subjected to annual pruning of fine branches, in Patos, PB, Brazil. The experiment consisted of two treatments (thornless and thorny "jurema-preta") in a complete randomized block design, with ten replicates of two linear plots subdivided in time. Forage mass and chemical composition of fine branches and the basal diameter of plants were measured during five years. Pruning decreased (p<0.05) increments in basal diameter and forage production. Annual dry matter yields reached 4,108 and 5,833 kg ha-1, respectively, for thornless and thorny plants, and forage quality was similar (p>0.05) for both genotypes. This roughage fodder (minimum NDF and ADF averages were 56±1.1% and 43±1.0%, respectively) had low P and K concentrations. Its average crude protein content was greater than 9.9±0.5%, which exceeds the minimum necessary for animal maintenance. Both "jurema-preta" genotypes tolerated pruning of fine branches and contributed with a significant amount of roughage fodder for animal maintenance in the dry season.
