We report the dose of sheep manure and POC concentration Poster which aims to study changes in the dose of sheep manure and Poster POC concentration on growth and yield of peanut (Arachis hypogea L.). This research is compiled in a randomized block design (RAK) factorial design consisting of two factors. The first factor sheep manure dosage form consists of three levels ie d1 (5 t ha-1), d2 (10 ton ha-1) and d3 (15 ton ha). The second factor in the form of the concentration of liquid organic fertilizer Poster consists of three levels ie p1 (1 ml-1), p2 (3 ml l-1) and P3 (5 ml l-1), respectively - each combination treatment was repeated 3 times. Different test average - average use multiplerange test duncant 5% significance level. Award dose sheep manure and POC concentration Poster melihatkan their interaction on plant height 9 MST, pong numberper plant and weight of pods per plant, giving a high dose of manure that requires  concentration POC rendah.

Effects of corn steep liquor (organic fertilizer, OF) and conventional chemical fertilizer (CF) on the growth and yield of bok choy (Brassica rapa var. chinensis) in summer and autumn hydroponic growing systems were compared. When OF and CF were applied with the same amount of total nitrogen in summer cultivation, there was no significant difference between yields; however, the growth rate in OF was slower than in CF. When OF was applied with twice the amount of nitrogen in CF (OF2), bok choy growth and yield were significantly inhibited in summer cultivation, likely owing to dissolved oxygen deficiency and different rates of nitrification and nitrogen absorbance by the plant root. Although the contents of potassium, calcium, and magnesium in bok choy showed no difference among the three treatments in both cultivation seasons, the carbon/nitrogen ratio tended to be higher in OF and OF2 than in CF. Lower nitric acid and higher ascorbic acid content was found in OF and OF2 than in CF. Overall, our results suggest that a comparable yield is expected by using the same nitrogen amount with a conventional recipe of chemical fertilization in autumn cultivation. However, further improvement of hydroponic management is needed in summer cultivation.

Abstract:An innovative approach, combining field-emission scanning electron microscopy (FESEM) with energy dispersive X-ray spectroscopy (EDX) analysis, is presented to investigate the degradation mechanisms affecting tannin-dyed wool. In fact, tannin-dyed textiles are more sensitive to degradation then those dyed with other dyestuffs, even in the same conservation conditions.FESEM-EDX was first used to study a set of 48 wool specimens (artificially aged) dyed with several raw materials and mordants, and prepared according to historical dyeing recipes. EDX analysis was performed on the surface of wool threads and on their cross-sections. In addition, in order to validate the model formulated by the analysis of reference materials, several samples collected from historical and archaeological textiles were subjected to FESEM-EDX analysis.FESEM-EDX investigations enabled us to reveal the correlation between elemental composition and morphological changes. In addition, aging processes were clarified by studying changes in the elemental composition of wool from the protective cuticle to the fiber core in cross-sections. Morphological and elemental analysis of wool specimens and of archaeological and historical textiles showed that the presence of tannins increases wool damage, primarily by causing a sulfur decrease and fiber oxidation.

Vegetable Cultivation

Vegetable cultivation is livelihoods for side Lake Batur communities, Kintamani, Bangli. Hilly natural conditions with a soil texture influenced by the eruption of Mount Batur, 900 m above sea level, and 900-3500 mm high rainfall, causing this region is very suitable for the cultivation of various vegetables, including shallot. One effort to meet the high demand for shallots is that efforts are made to improve cultivation techniques, including fertilizing to improve yields. In modern agriculture, the use of fertilizer is absolutely essential to trigger the level of crop production. The aims is to analyze the combination effect of using of inorganic fertilizer (ZA fertilizer) and organic fertilizer (compost fertilizer) on shallot vegetable cultivation systems on the content of pollutants, N nutrients and onion crop yields on the shores of Lake Batur, Kintamani District, Bangli Regency. The study using RBD with two factors where factor I: provision of organic fertilizer is leaf compost made aerobically (O), consisted of 3 levels, namely: O0 = 0*, O1 = 5* and O2 = 10*and factor II: the application of inorganic fertilizer namely ZA (S) fertilizer, consisted of 3 levels, namely: S0 = 0**, S1 = 50** and S2  = 100**, each repeated 3 times. The parameters observed were the growth and yield of shallots as well as the content of Pb, Zn, Cu and N nutrients in the soil. The nutrient content (N) in the soil, when using chemical fertilizer ZA and compost organic is not significantly different, as well as the results of onion plants, while the content of Pb, Zn and Cu on the use of chemical fertilizer ZA and organic compost, very real different. The highest soil Pb content in S2O1 treatment is 30.07***, the highest soil Zn content in the S2O1 treatment was 28.24***, and the highest soil Cu content in the S1O2 treatment is 17.22***. *= tons/ha **= kg/ha ***= mg/kg Keywords: compost; contents Pb; Zn; Cu of soil; shallot; ZA.
