Cr Concentration

Tannery sludge contains high concentrations of inorganic elements, such as chromium (Cr), which may lead to environmental pollution and affect human health The behavior of Cr in organic matter fractions and in the growth of cowpea (Vigna unguiculata L.) was studied in a sandy soil after four consecutive annual applications of composted tannery sludge (CTS). Over a four-year period, CTS was applied on permanent plots (2 × 5 m) and incorporated in the soil (0-20 cm) at the rates of 0, 2.5, 5.0, 10.0, and 20.0 Mg ha-1 (dry weight basis). These treatments were replicated four times in a randomized block design. In the fourth year, cowpea was planted and grown for 50 days, at which time we analyzed the Cr concentrations in the soil, in the fulvic acid, humic acid, and humin fractions, and in the leaves, pods, and grains of cowpea. Composted tannery sludge led to an increase in Cr concentration in the soil. Among the humic substances, the highest Cr concentration was found in humin. The application rates of CTS significantly increased Cr concentration in leaves and grains.

The study aimed to determine the effect of organic planting media and the position of seed planting on the growth of Robusta coffee seedlings. The study is conducted at the Tabanan Agrotechnology Study Program, Tabanan University, which conducted from July 2019 to September 2019. The treatments are arranged in factorial in a randomized block design (RBD). Two treatments examined in this study were the doses of organic matter in the growing media (0g, 150 g, 300 g, 450 g) and seed position (prone position, upside down, tilted position). The results show that the interaction between organic planting media (soil + coffee leaf compost) and seed planting position did not significantly affect all coffee seedlings growth variables. The dose of organic compost in the growing media has a very significant effect on all growth variables except when growing and the percentage of growth. The dosing of 450 g organic matter gave the highest root fresh weight, fresh stem weight and fresh leaf weight (1.00 g, 2.97 g and 8.64 g respectively) and oven dry weight for the three variables (respectively 0.39 g, 0.55 g and 1.36 g). Seed planting position has no significant effect on all observed variables, but there is The tendency of planting position with the prone on average gives better growth compared to other positions.

Andisols  are characterized  by  dominance  of  amorphous  minerals  which form strong and stable bonding with organic matter, therefore Andisols always contain high organic matter. For that reason, organic fertilizer is generally not applied  on  Andisols,  because  it  is  assumed  that  it  will  not  give   any  positive effect  on  growth  or  yield.  The  experiment  was  aimed  to  evaluate  response  of mature Kartika 1  Arabica coffee variety (seven years old) cultivated on  Andisols applied with organic matter derived from cow dung manure. The experiment was carried out at Andungsari  Experimental Station located in Bondowoso District, East  Java. Elevation of the site was 1,150 m asl., with rainfall type of C (Schmidt &  Fergusson).  The  experiment  was    arranged  according  to  completely randomized  block  design  with  four  replications  to  evaluate  effect  of  ninecombination  treatments  of  application  rates  at   application  depths  of  50,  100, and 150 cm. The  range of organic fertilizers rates were  0 - 13.5 kg/tree/year. The experiment revealed that cow dung manure applications on Arabica coffee cultivated  on  Andisols  significantly  increased  yield  at  the  average  of  33% compared  to  the  untreated  crop.  No  significant  effect  of  the  treatment  onvariables of leaf water deficit and soil moisture content during dry season and root  density.  At  range  of  application  depths  of  50  -  150  cm,  the  deeper  the organic matter applications, the higher the yield will be.Key words: Andisols, Arabica coffee, organic matter, cow dung manure

Abstract Nowadays, shallot is important horticultural crops in Maluku include in Tual City, Maluku Province. For ensuring the macronutrients level in soil and yield during shallot cultivation, fertilization composed of chemical, organic and bio fertilizer is needed. The objective of field experiment was to evaluate the effect of mixed biofertilizer integrated with organic matter on total nitrogen and available phosphorous in soil as well as shallot yield grown in Vertisols of Tual. The experiment was setup in randomized block design with four treatments of compost and chicken manure amendment with and without biofertilizer containing N-fixing bacteria and P-solubilizing. At the vegetative stage, consortia biofertilizer combined with either compost or chicken manure increased plant height and soil reaction but decreased the available phosphate (P) and didn't change nitrogen (N) total in soil. Chicken manure amendment combined with biofertilizer inoculation increased dry weight of shoots and bulbs even though didn't significantly differ with other treatments. Nonetheles, that treatment resulted in high yield of shallot bulbs up to 14 t/ha.

<title>ABSTRACT</title><p>The aim of this study was to evaluate the yield and nutrition of castor bean in response to fertilization with sewage sludge and potassium (K) and magnesium (Mg) sulphate. The experiment was carried out from January to July 2011. The treatments, in a randomized block design with three replicates, in a Nitosol, corresponded to a factorial scheme (2 x 4 +1): two doses of K and Mg sulphate combined with four doses of sewage sludge (0, 2.60, 5.20 and 10.40 t ha<sup>-1</sup>, dry basis), applied based on its nitrogen (N) content and the N requirement for the crop and an additional treatment with NPK. The castor bean grain yield fertilized with sewage sludge did not differ from conventional fertilization, with the maximum value achieved at a dose of 7.5 t ha<sup>-1</sup> of sewage sludge. The fertilization with sewage sludge increased zinc and copper levels in the soil to values close to or higher than those in conventional fertilization, without any influence on the concentrations in the leaf. Fertilization with K and Mg sulphate increased the levels of these cations in the soil without affecting the concentrations in the leaves. The fertilization with sewage sludge increased the contents of organic matter, sulfur, zinc, iron, copper and boron in the soil, and manganese and boron in castor bean leaves.</p>

An important aspect in the cultivation of vegetables is the quality of the product to be marketed, free from dirt and damage and the practice of mulching could be an option, but there is scarse information. The aim of this study was to evaluate the influence of mulching on the production traits of three cultivars of Pak Choi. The experiment was set up during March to May 2013 using a split plot randomized block design, with four replications. Soil cover treatments (white agrotextile, black agrotextile, black plastic, silver plastic, tifton straw and bare soil) were arranged in the plots, and three cultivars of Pak Choi (Green Pak Choi, White Pak Choi and Chingensai Natsu Shomi) in subplots. Height and diameter of shoots, number of leaves, fresh weight of the head and petiole, base diameter, dry weight of stem, petiole, and leaf were evaluated thirty-five days after transplantation. The total dry weight and leaf area were measured, and then we estimated the yield. There was a significant effect of soil cover and cultivar. In general, the cover with synthetic materials showed higher values on production of Pak Choi. The cultivar White Pak Choi was better adapted to the growing conditions, with an average yield of 57.78 t/ha.

Ad Libitum Intake

Six mature Merino sheep received three treatments in a randomized block design experiment. The treatments were: chopped oaten hay diet at 90% of ad libitum intake without urea (L); the ciet offered at the same level as for L with urea infused into the rumen at 11.5 g kg-1 dry matter intake (LU); and the diet offered at 90% of the ad libitum intake achieved with urea infused at 11.5 g kg-1 dry matter intake (HU). Sheep given HU consumed 37% more (P < 0.01) organic matter (OM) than those fed L or LU, but the apparent digestibility of OM did not vary (59.2-61.8%) between treatments. The addit onal food consumption was associated with c. 20% increase (P < 0.05) in the weight of OM in the reticulorumen and significantly higher (by 10-35%; P < 0.05) fractional outflow rates of most dietary and microbial constituents of digesta. The fractional digestion rate of potentially digestible plant cell walls was not affected by urea, but the flow of microbial non-ammonia nitrogen from the abomasum was enhanced (L, 7.0; LU, 8.2; HU, 12.5 g day-1; P < 0.05). The results of this study suggest that the stimulatory effect of urea upon food intake was associated with the provision of additional microbial protein for digestion in the intestines, rather than changes in the rate or extent of organic matter fermentation in the reticulorumen.

This study aimed to investigate the effect of adding multi nutrient sauce to rations on the digestibility of dry matter and organic matter in sheep. This research was conducted in May--July 2019 in Kebagusan Village, Gedong Tataan District, Pesawaran Regency. Analysis of feed ingredients and feces was carried out at the Animal Nutrition and Feed Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. This research was conducted experimentally using the Randomized Block Design (RBD) method. Sheep were divided into six groups based on body weight, namely group 1 (11,18--13,18 kg), group 2 (13,97--14,13 kg), group 3 (14,31--14,51 kg), group 4 (14,89--15,91 kg), group 5 (16,35--16,66 kg), and group 6 (17,15--17,77 kg). Each group consisted of 3 sheep. Treatment given were R0: basal ration formulated by farmer (forage silage + cassava byproduct), R1: R0 + 5% multi nutrient sauce, R2: R0 + 10% multi nutrient sauce. The results showed that the addition of 10% multi nutrient sauce was the best treatment that could improve the digestibility of dry matter and organic matter in sheep.   Key word : Multi nutrient sauce, Dry matter digestibility, Digestibility of organic matter, Sheep.
