The size of the container can affect the quality of the seedlings and, there is no recommendation of containers for the formation of flamboyant seedlings [Delonix regia (Bojerex Hook.) Raf]. Thus, the objective of this study was to evaluate the production of flamboyant seedlings in different container sizes, besides performing trail analysis to identify the growth variables that characterize the quality of these seedlings. The experimental design was a randomized block design with seven container sizes (13 × 13 cm, 15 × 15 cm, 13 × 20 cm, 15 × 25 cm, 17 × 22 cm, 17 × 30 cm or 30 × 40 cm), with four replicates. Each experimental unit was composed of five containers, totaling 20 containers per treatment. The plant height, stem base diameter, number of leaves and the sturdiness quotient were measured at 20, 40, 60, 80 and 100 days after emergence (DAE), and at 100 DAE were also measured the root volume, root dry matter, shoot dry matter, total dry matter, shoot/root dry matter ratio and Dickson quality index (DQI). The flamboyant seedlings have better grow when cultivated in polyethylene bags with size of 30 × 40 cm. The collar diameter, root volume, root dry matter, shoot dry matter and total dry matter are the most adequate variables to indicate the quality of flamboyant seedlings. However, because it is a rapid, simple and non-destructive measurement variable, the root collar diameter is more adequate to identify high-quality flamboyant seedlings.

ABSTRACT: The production and quality of roses are influenced by fertilization management. The aim of this experiment was to evaluate the effects of doses of iron (Fe) in the production of potted rose bushes ( Rosa hybrida ). Treatments were based on five doses of Fe (0, 1, 3, 5 and 15mg kg-1) applied on the substrate, in a randomized block design with four replications. Seedlings presented two pairs of leaves and were individually transplanted into plastic pots (0.8dm3) containing commercial substrate. Each experimental plot consisted of a vase with a plant with two flower stalks. The following parameters were evaluated: number of leaves and flowers per flower stalk; dry matter production of roots, leaves and flowers; plant height and diameter and floral longevity. In addition, foliar levels of total chlorophyll and Fe were determined. Fertilization with Fe increases the production and quality of flowers of the rosebush cv. 'Shiny Terrazza' (r). Dose of Fe to be added to the substrate used in this study for maximum economic efficiency for this cultivar is 3.6mg kg-1.

The objective of this study was to evaluate different textures and storage forms of corn in piglet diets. Two experiments were conducted, one of which tested digestibility of nutrients and the other diet performance. In the digestibility trial, 24 crossbred (Landrace X Large White) barrows with an initial weight of 18.7 ± 1.5 kg were used. They were kept in metabolic cages in a randomized block design using the factorial arrangement 2 X 2 (type of corn - dent and flint X type of storage - moist grain silage and dry grain) and six replicates, with one animal as the experimental unit. The values of metabolizable energy (ME) obtained were 3841 kcal of ME/kg of dry matter (DM) from dry corn, 3912 kcal of ME/kg of DM from moist corn, 4022 kcal of DM from ensiled dry corn and 3928 kcal of ME/kg of DM from ensiled humidity corn. The ensilage process increases the digestibility coefficient of dry matter and crude protein and increases the digestible energy of the diets, independent of the process form. The type of corn did not influence these variables. In the performance trial, 60 barrows (initial weight of 6.5 ± 1.5 kg) of the same stock were used during 28 days of post-weaning distributed in the same experimental design, with five replicates and three animals as the experimental unit. The treatments did not influence the daily weigh gain or the daily feed intake. The dentate corn and the ensilage process decreased the feed conversion of the independent form (no significant interaction). The substitution of dry for ensilage corn increased the digestibility of the nutrients in the diets and the feed conversion of the piglets from 7 to 15 kg. Dentate corn promotes best feed conversion in this phase.

ABSTRACT Okra, Abelmoschus esculentus (L.) Moench, is a vegetable with annual fruit native to hot regions of Africa, well adapted to the conditions of the Northeast and Southeast regions of Brazil, where it is widely used by small farmers. This study aimed to evaluate the effect of mineral and organic fertilization on the production and quality of okra fruits. The experiment was conducted in randomized block design, with three replicates and eleven treatments defined according to a Baconian matrix. Treatments consisted of doses of N (0, 100, 200 and 300 kg ha-1), P (0, 100, 200 and 300 kg ha-1) and K (0, 80, 160 and 240 kg ha-1), as well as absence and presence of organic compost (30 t ha-1). The following parameters were evaluated: plant height, stem diameter, number of leaves, production of fruits plant-1, number of fruits plant-1, fruit length and diameter and fruit quality (pH, soluble solids, titratable acidity, vitamin C and electrical conductivity). The crop is demanding in terms of K and N fertilizations, with increments of 15.8 and 36% in the mean number and diameter of fruits, respectively. Organic fertilization did not influence the vegetative growth of okra, but was beneficial to the production of fruits with higher vitamin C content, 52% higher than the contents found in fruits produced without such input.

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

The objective of this study was to evaluate the yield and physiological quality of bean seeds in two agricultural crops, and the chemical composition of seedlings submitted to adverse temperatures during germination. For the field experiment, a randomized block design was used, using five genotypes, BRS Embaixador, IPR Tuiuiú, Guabiju, Carioquinha and Mouro, arranged in four replicates. The experimental units were composed of five lines with five meters in length, where 25 plants were randomly collected per experimental unit to measure the characters of interest. For laboratory testing the seeds produced were submitted to three temperatures (15, 25 and 35°C) during germination under controlled conditions. The evaluated characters were: grain yield, mass of a thousand seeds, germination, first germination count, starch content, soluble sugar, soluble protein and total amino acids. The data were submitted to analysis of variance and later compared by the Tukey test. Yield per plant revealed changes between the agricultural crops, as well as among the genotypes tested. Germination and the first germination count revealed higher magnitudes in seeds produced by BRS Embaixador, IPR Tuiuiu and Carioquinha genotypes. For all genotypes, protein and amino acid levels were higher in seedlings submitted to lower temperatures. The levels of starch and total soluble sugars were higher in seedlings produced at 35°C. Yield, seed physiological quality and chemical composition of seedlings are influenced by the crop and genotypes tested.

The utilization of brewery waste in ration to improved the quality of lamb meatABSTRACT. An experiment has been conducted to study the utilization of brewery waste in ration to improved the meat quality of lamb. High quality of lamb meat can be reached by manipulation of rumen fermentation. Tannins in brewery waste can decrease the activity of rumen microorganism and inhibite the rumen biohydrogenation processes. The experiment was conducted with an experimental method by in vivo technique, using 16 heads of local lamb, 4-5 months old, with body weight range of 5-10 kg.  The trial was conducted for 150 days, using Completely Randomized Block Design with 4 replicates. The treatment tested were 4 levels of Brewery Waste : R1 = 12%; R2 = 24%; R3 = 36% and R4 = 48%. The variables measured were : physical and chemical quality of meat. The result indicated, that the treatment tested significantly affect the meat quality physically, except to the percentage of edible distal meat and proximal bone weight.Based on the all variables measured, the research conclusion : (1) the utilization of brewery waste up to 48% dry matter  ration, could be used, without any physiology and metabolism disturbance; (2) the highest increasing of unsaturated fatty acid was stearic acid (C18:0) as much as 54. 60%, was reach by R3 (36% brewery waste); the linoleic acid increased as much as 43.91% reach by R4 (48% brewery waste);  the oleic acid increased as much as 37.48% by R2 ( 24% brewery waste). From the result can be suggested that the need of tannin brewery waste as biohydrogenation inhibitor would be more effective and efficient whenever brewery waste usage has been increased up to 60% dry matter ration.

ABSTRACT The use of mini-cuttings is an option for obtaining sweet potato propagules of excellent quality. The objective of this research was to evaluate the production and quality of sweet potato roots propagated by mini-cuttings in different types of trays and ages of seedlings. Six treatments, resulting from the factorial 2x3, were evaluated: two types of trays (162 and 200 cells, with 31 and 18 mL of substrate per cell, respectively) and three ages of seedlings (39, 46 and 53 days after placement of mini-cuttings in trays), in a randomized block design, with five replications. Seedlings characteristics, production and quality of roots were evaluated. Higher number and dry weight of leaves per seedling were observed in the tray with 162 cells than in trays with 200 cells. The younger seedlings (39 days) had a lower number of leaves, dry weight of leaves, stem, roots ant total (leaves + stem + roots) than seedlings of other ages. There was no difference in root production depending on the type of tray, regardless of the age of the seedlings. For the 162-cell tray, the age of the seedlings did not affect the production of roots. On the other hand, for the 200-cell tray, higher roots production was observed on seedlings 39 days age compared to seedlings with 53 days. No differences were observed among the roots of different treatments for titratable acidity, and levels of sucrose, reducing sugars ant total sugars. It is recommended to avoid old seedlings, that is, it is recommended to use seedlings with a maximum of 43 days after planting of mini-cuttings for trays with 200 cells, while for trays with 162 cells no difference in root production was observed with the different ages of the seedlings.

ABSTRACT Euterpe precatoria Mart. has been demanded due to the functional characteristics of its fruits and, therefore, its planting has been encouraged. However, there is a lack of information about the seedling production system of this palm tree. Neither a favorable environment nor the amount of fertilizer in the substrate have been defined for the production of healthy and vigorous seedlings. This study aimed to evaluate the effect of environments and doses of a slow-release fertilizer on the production of E. precatoria seedlings. The experiment was conducted in a randomized block design, with three replications and ten plants per plot. The treatments were arranged in a 4 x 5 factorial scheme, with four environments (under shading levels of 20 %, 30 %, 50 % and 75 %) and five doses of a slow-release fertilizer (0.0 kg m-3, 2.5 kg m-3, 5.0 kg m-3, 7.5 kg m-3 and 10.0 kg m-3 of substrate). The seedling height; root collar diameter; number of leaves; leaf, shoot, root and total dry mass; and the Dickson quality index were analyzed. There were significant interactions between the shaded environments and slow-release fertilizer doses for all the analyzed variables. The 75 %-shaded environment yielded better quality seedlings. The slow-release fertilizer can be used to produce E. precatoria seedlings in environments under shading levels of 50 % and 75 %, being the 4.60 kg m-3 and 8 kg m-3 doses, respectively, the most recommended ones.
