ABSTRACT This study aimed to evaluate the effect of applying increasing doses of biofertilizer obtained by the anaerobic digestion of cassava effluent on the development of crambe plants. The experiment was conducted in a protected environment at the Federal University of Paraná (UFPR), Palotina Sector, between April and August 2015. A completely randomized design was used, and five different treatments with the following doses were applied in five replicates: 0, 40, 80, 120, and 160 kg ha-1 of K2O. The following parameters related to plant development were evaluated: final height, stem diameter, number of branches, dry shoot and root biomass, mass of the grains, and oil content. The 160 kg K2O ha-1 dose was found to have the best influence on the plant development, because all the measured parameters reached their highest values at this dose, except for oil content, which attained the highest percentage in the case of the control treatment (0 kg ha-1 of K2O). This study proved that the biofertilizer obtained by anaerobic digestion of cassava effluent can be used as an alternative to regular fertilizers in cultivating crambe.

Homeopathic medicine is a discipline of universal medical science, with increasing application in humans, animals and plants. The acceptance of agricultural homeopathy is increased by the safety and proven effectiveness of its ultra-diluted and agitated medicines, to stimulate the germination, development, growth and production of various plant species. The present work aimed to evaluate the effect of homeopathic medicines on physiological indicators and the development of Yorimón beans (Vigna unguiculata L., Walp.) var. Paceña. A completely randomized design was used with two homeopathic treatments, Manganum metallicum 31CH (MnM-31CH), Magnesium-manganum phosphoricum 3CH (MaMnP-3CH) and as a control treatment destilled water (DW), with six replicas per treatment. Photosynthetic rate, perspiration, total chlorophyll, leaf area and fresh and dried biomass of root, stem and leaves were evaluated. An analysis of variance was applied and when there was a signif icant difference between treatments, a comparison of means (Tukey HSD, P ≤ 0.05). The results revealed a signif icant increase for all the variables evaluated with respect to the control treatment (DW), in the plants that received treatments (MnM-31CH and MaMnP-3CH). Fresh root biomass was the response variable with the highest percentage increase (111.2%) and was recorded in the plants treated with MnM-31CH, compared to the plants in the control group, without medication (DW). Likewise, in the treated plants (MnM-31CH and MaMnP-3CH) there was an increase greater than 40% in total chlorophyll and in photosynthesis. This conf irms the effectiveness of applied treatments and reveals potential of agricultural homeopathy, as an alternative to achieve greater eff iciency in the cultivation of V. unguiculata.

The present research was conducted on two factor Completely Randomized Design (CRD) with eight treatments and three replications. A set of experiments were carried out to evaluate the effect of postharvest ethephon treatment and packaging on ripening of mango cv. Maldah. The treatments consisted of ripening agent i.e., ethephon and control treatment under different packaging condition i.e., fiber with hole, fiber without hole, plastic with hole and plastic without hole. The result revealed that different packaging condition and ripening agents influenced the ripening behavior of mango. The highest TSS (15.26), sugar-acid ratio (23.66) and juice content (126.05) were recorded with fiber (without hole) and the lowest TSS (12.60), sugar-acid ratio (9.01) and juice content (116.05) with plastic (without hole). The highest TA (1.44) was recorded with plastic (without hole) and the lowest (0.66) with fiber (without hole). Similarly, the highest BT (2.83) was recorded with fiber (with hole) and the lowest (1.66) with plastic (without hole). Firmness, sweetness, TSS and juice content were the highest with the interaction effect of fiber bag (without hole) and ethephon treatment. In conclusion, mango fruits with ethephon treatment packed in fiber bag (without hole) enhances quality and ripening of mango whereas under controlled condition and without hole plastic packaging mangoes had low quality performance in terms of physio-chemical properties.

ABSTRACT Methionine is an essential amino acid, and generally, the first limiting one in the diets of tambaqui, the main native fish produced in continental aquaculture in South America. However, there is a lack of information on their amino acid requirement, especially for maintenance and efficiency of utilization. The present study aimed to determine the requirement of [methionine plus cystine] for the maintenance and efficiency of utilization using tambaqui of different body weights. Two experiments were carried out using 250 tambaqui with weights of 100 and 300 g. They were distributed in a completely randomized design with four treatment groups (0.264, 0.396, 0.528, and 0.660% of digestible [Met + Cys]), five replications. The control treatment (CT) was performed with the addition of methionine at the first level (0.264%) until the second level was reached (0.396%). The maintenance requirement was determined by the regression analysis between the consumption of [Met + Cys] and protein retention equal to zero. The efficiency was determined using the value of the slope coefficient of the line obtained by the linear regression. The protein and methionine retention values of tambaqui weighing 100 to 300 g were compared by the parallelism test, and no difference was observed between the parameters of the equations indicating the need for only one equation to describe the responses to body weights. The requirement of digestible [Met + Cys] for the maintenance of tambaqui with weights from 100 to 300 g was 60.47 mg kg-0.7 day-1 and the efficiency of utilization of 42%.

Hybrid moth orchid (genus Phalaenopsis) is one of the most popular ornamentals in Indonesia. It has beautiful and long-lasting flowers, but cultivating this orchid is still become a challenging issues due to the need of specific condition to grow and long time period to re-blooming. Plant growth regulators (PGR) (i.e. Benzyladenine (BA)) has been widely documented as a flower-inducing substance in several orchids. However, the optimal concentration and its mechanism in inducing flower-stalk bud and re-blooming is still unclear. This research aimed to study the effects of BA application in the form of lanolin paste on hybrid Phalaenopsis flower-stalk buds. We conducted this study using completely randomized design with four replications at the greenhouse laboratory Faculty of Agriculture University of Lampung on August to December 2018. We divided the orchid into 5 group of BA concentration (0, 1000, 1500, 3000, or 6000 ppm). The sheath of the fourth or fifth buds of the flowers were carefully opened, then it smeared with BA. The percentage of bud break into flower spike or keiki, length of shoots or spike and number of open flowers were recorded until 10 weeks of observation. The results showed that, neither of the buds under the control treatment (without BA), 1000 ppm nor 1500 ppm BA broke and grew into keiki or spike. On the other hand, application of BA at 3000 ppm or 6000 ppm successfully induced 100% flower spikes on the buds treated. No keiki was formed in all buds treated. In addition, treatment of the buds with 6000 ppm BA produced longer flower spikes as well as more open flowers. We conclude that the application of BA (minimal 3000 ppm) successfully induced flower spike of  hybrid Phalaenopsis.

Miltonia flavescens is a species vulnerable to extinction, which justifies research on preservation methods. Cryopreservation in liquid nitrogen (LN) consists of maintaining biological material at a low-temperature (-196 °C). Thus, the aim of the experiment is to evaluate the influence of different cryoprotective solutions on cryopreservation in LN of the Brazilian orchid Miltonia flavescens seeds. The experiment was conducted in a completely randomized design (CRD), with eight treatments and six replications. The treatments were composed as follows: control; immersion in LN, no cryoprotectant adding; and immersion in LN, with the addition of cryoprotectants: sucrose 0,4 mol L-1; glycerol 2 mol L-1; protection by vitrification in solution (PVS)1; PVS2; PVS2 + 1% phloroglucinol, and PVS3. Except for the control treatment, which was kept in a freezer (10±2 °C), the others remained frozen for 15 days. After this period, the viability of the seeds was evaluated. These seeds were sown and, 30 days after germination, then the frequency of protocorm formation was verified. Before the cryopreservation, the seeds showed 75% viability and 9.5% water content. After cryopreservation, the seeds varied between 67 to 75% viability. However, treatment with glycerol 2 mol L-1 exhibited lower performance than the others (58%). The control treatment showed a higher percentage of protocorm formation (71%) followed by treatments PVS1 (63%), PVS2 (64%), and PVS2PHLO (66%). For the purpose of preserving Miltonia flavescens seeds in liquid nitrogen for a prolonged period, the treatments PVS1, PVS2, and PVS2PHLO proved to be viable and promising alternatives.

Abstract The objective of this study was to investigate the effects of different Se sources and concentrations on glutathione forms and cholesterol metabolism in beef cattle. Sixty-three Nellore bulls (412 ± 19 kg BW; 24 months old) were randomly assigned to a completely randomized design in a 2×3 + 1 factorial arrangement (63 pens; one animal/pen) with two Se sources (sodium selenite, ING and Se-yeast, ORG), three concentrations (0.3, 0.9 and 2.7 mg supplemental Se/kg DM), and control treatment (without Se supplementation) fed for 90 days. Blood samples were collected on d 0, 28, 56, and 84. Muscle and liver samples were collected at harvest. Hepatic GSSG (P = 0.004), GSH/GSSG ratio (P = 0.030), and GSH-Px (P = 0.004) were affected by Se source x concentration interaction. Oxidized glutathione was higher in the ORG group vs. ING at concentration 2.7 mg supplemental Se/kg DM, but at 0.3 mg supplemental Se/kg DM the ING group was higher than ORG. The liver GSH-Px activity was higher in the ORG group vs. ING at concentration 0.9 and 2.7 mg supplemental Se/kg DM. The GSH/GSSG ratio was the highest in animals fed 0.3 mg supplemental Se/kg DM of ORG. Selenium liver concentration increased linearly with the supplemental Se concentration in the diet (y = 0.0583 + 0.4254x, R 2 = 0.92, P < 0.0001), regardless of source. Total meat cholesterol was greater (P < 0.001) in CON (control) vs. SUP (supplemented, regardless source) group. The muscle GSH-Px activity was higher (P < 0.001) in SUP vs. CON and increased (P < 0.004) with increasing supplemental Se concentrations. There was an increase on VLDL, glucose, and triglycerides in ORG vs. ING (P ≤ 0.035). In general, serum Se was higher (P < 0.001) in SUP vs. CON and increased with increasing supplemental Se concentration. Lastly, the HMGCR concentration was lower (P = 0.002) in SUP (0.39 ng/mL) vs. CON (0.55 ng/mL). Selenium supplementation with different sources and concentrations has the potential to affect cholesterol metabolism by affecting GSH/GSSG ratio, GSH-Px, and the HMGCR.

SUMMARY This study was performed to evaluate the effect of the inclusion of paprika and marigold extracts in sorghum-based rations on the productivity and egg quality of laying hens. One hundred sixty laying hens were distributed in a completely randomized design in five treatments and in a factorial arrangement (2 × 2 + 1), one control ration based on corn, two levels of paprika extract (0 and 6 g/kg diet), and two levels of marigold extract (0 and 1 g/kg diet) in sorghum-based rations. There was no effect (P > 0.05) of the treatments on the weight, specific weight, and Haugh unit of the eggs and productive performance, but the inclusion of paprika extract resulted in eggs with lower egg pH. The interaction between the control group and the factorial was significant (P < 0.05) to the laying rate, egg mass, and yolk color, whose values were lower with sorghum-based diets with no pigment compared to control treatment. The interaction between the paprika and marigold extracts was significant increasing the height (P < 0.03) and color (P < 0.0001) of the yolk when paprika extract was used, with or without marigold extract. Marigold extract inclusion reduced the percentage (P < 0.02) and thickness (P < 0.01) of the eggshell. As conclusion, the inclusion of paprika extract in sorghum-based diets for laying hens is viable for improving the egg quality.

ABSTRACT: Campomanesia adamantium is a native fruit species of the Cerrado and is used in food and medicines and as bee pasture. The chemical composition of essential oils obtained from plants of the same species have varying constituent proportions due to the influence of extractive factors, environmental, genetic and ontogenetic. This study aimed to identify the influence of hydrodistillation time on the content and chemical composition of essential oil extracted from the leaves of C. adamantium . Treatments consisted of five extraction times (1, 2, 3, 4, and 5h) using Clevenger with five replications in a completely randomized design. It was observed that after two hours of hydrodistillation, the essential oil content remains constant. Regarding the chemical constituents of essential oil, variation of the proportions of the compounds tested occurred at all hydrodistillation times. The compounds spathulenol oxygenated sesquiterpenes and caryophyllene oxide were the majority in the five hydrodistillation times.
