It is the purpose of this study to evaluate the agronomic behavior and yield of the Tifton 85 grass (Cynodon dactylon Pers), when used in the treatment of swine wastewater (SW) with constructed wetland systems (CWs). For this purpose, five tanks were built measuring 24 x 1.1 x 0.7 m, damp-sealed with PVC canvas and filled with 0.4 m crushed stone. In two of these tanks, Tifton grass was cultivated: one of the tanks (CW 3) contained the grass, and in the other (CW4) the grass was only cultivated in the final third part of the tanks, being preceded by Alternanthera (Althernanthera philoxeroides) and cattail (Thypha latifolia L.). The SW was previously treated by means of a filtration process that consists of 0.7 m - high organic filters; the filtering beds were made of chopped sugarcane bagasse. The filter effluents were applied to CWs at a 0.8 m³ d-1 flow rate, corresponding to a hydraulic detention time of about 4.8 days. During the experimental period, three cuttings were done in CWs plants in order to evaluate the dry matter yield and the nutrient extraction capacity. All plants showed satisfactory performance in dry mass yield (86.3 and 65.3 t ha-1, in CW3 and CW4 respectively) and nutrient extraction, as well as in dry matter yield. Except for the case of Zn, the cultivation of other vegetable species in the same tank did not alter the capacity of the Tifton 85 grass extraction of the SW macro and micronutrients removal.

Nutrient Extraction

The plant productivity and extraction capacity of nutrients present in swine wastewater (SWW) were quantified over 60 days in three horizontal subsurface flow constructed wetlands (HSSF-CW) grown with three different plant species (Typha latifolia, Alternanthera philoxeroides and Cynodon dactylon). The results show the decay of the dry matter yield (DMY) and the nutrient extraction capacity (NEC) by the plants throughout the system, which gave rise to the equations that relate these parameters to the hydraulic retention time (HRT) for each species. When possible, general equations that are independent of the plant species were also evaluated. The best model fit for the dry matter yield and N-total, N-ammoniacal, N-nitrate and P extraction by plants as a function of HRT was the decreasing potential and for K extraction was the linear regression. The coefficients of determination of equations for the species Alternanthera philoxeroides and Cynodon dactylon were, for the most part, higher than 0.8. On the other hand, the general equations presented coefficient of determination greater than 90% in all cases.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.

The objective of this work was to evaluate the productivity of maizedry matter in the consortium with forage or in single cultivation, oats + ryegrass in succession and the physical attributes in a Red Nitosol. The experiment was conducted in Concórdia -SC in the agricultural years 2016/2017 and 2017/2018. The design wasa randomized block with 5 replications, consisting of the treatments: T1 -Single maize; T2 -Maize + Pigeon pea forage (Cajanus cajan); T3 -Maize + Urochloa ruziziensis; T4 -Maize + Pigeon peaforage + U. ruziziensis, T5 –Pigeon peaforage and T6 -U.ruziziensissingle. The dry mass productivity (PMS) of maize, forage and oats + ryegrass in succession was determined. Also, the Rapid Diagnosis of Soil Structure (DRES) and the Mechanical Resistance of Soil to Penetration (RSP) were carried out after twoyears of cultivation. The presence of U. ruziziensisand / or Pigeon peadid not affect the dry matter yield of maizein both harvests. The highest PMS of oats were found in the plots following single maizeand the smallest for the second crop, where treatments with U. ruziziensisfollowed. For RSP, no significant differences were found in consortia and single crops. The treatments with U. ruziziensisobtained better indexes of structural quality. The corn consortium with Urochloa ruziziensis, in addition to not reducing silage productivity, provides forage availability in the autumn empty period, as well as improving soil attributes.

AbstractThe objective of this work was to evaluate the influence of the form of raw sanitary sewage (RS) application in closed-end and level-bottom furrows on the dry matter yield and macronutrient extraction capacity (extraction of nitrogen, phosphorus and potassium) by the aerial part (stem and leaves) of elephant grass. Fertigation of elephant grass with RS were conducted for 3 uninterrupted years, and the RS application dose was established as a function of the amount of sodium fed to the soil (300 kg ha−1 year−1). In the experimental planning four treatments were established, where two experimental plots received RS and the water demand was complemented by treated water from the public supply network (TW), with and without alternation in the position of RS application in the furrows (TFA and TFN, respectively); and as a control there were two experimental plots in which the plants received conventional mineral fertilization, where the grass was irrigated with TW, with and without alternation in the position of water application in the furrows (TWA and TWN, respectively). The greatest mean dry matter yield (29.9 Mg ha−1 year−1) and mean macronutrient extraction values were found for plants submitted to TFA (688, 102, 508 kg ha−1 year−1 of N, P and K, respectively), compared to those obtained in the other treatments.

Calceolaria x herbeohybrida Voss (pocketbook plant, calceolaria) is an herbaceous perennial and floriferous species that can be grown in pots or beds. Nitrogen is usually the most required nutrient, being necessary to conduct studies in order to provide useful information for agronomic practices. Thus, this study aimed to evaluate nitrogen doses in the growth of Calceolaria x herbeohybrida in pots. Initially, assorted and pelleted calceolaria seeds were sow in multicellular trays containing a commercial substrate based on peat and kept in a floating irrigation system in a protected environment. At the greenhouse, seedlings with four true leaves were transplanted into 1 L pots containing the same substrate and a drip irrigation system. The treatments consisted of different nitrogen doses (0.0, 0.5, 1.0, 2.0 or 4.0 g of N L-1) applied weekly using ammonium nitrate as source. Fertilization with P and K was also done, and all treatments received de same dose. At the end of the experimental period, shoot length, leaf area, shoot and root dry matter, number of buds and flowers, chlorophyll a, b and total chlorophyll were evaluated. The experimental design was completely randomized with four replications and five plants per plot. The data were treated with ANOVA and the means were treated with regression analysis using the SigmaPlot 11.0 software. There was no survival of plants at the highest N dose (4.0 g L-1). Shoot length showed a quadratic behavior, with a maximum point at 1.25 g L-1, where plants reached 13.3 cm. There was a similar behavior for the variable leaf area, with the highest point at 1.24 g L-1. Shoot dry mass presented the maximum point at a dose of 1.20 g L-1, resulting in 4.21 g of dry matter. Regarding root dry matter, no equation could be adjusted. For the variable number of buds and flowers, the highest point was at a dose of 1.20 g L-1, with 35.86 buds and flowers per plant. For chlorophyll a, b and total chlorophyll, the maximum point was at 1.5 g L-1. The ideal nitrogen dose is between 1.2 and 1.5 g L-1 for most variables.

The treatments consisted of five doses of the copolymer (0, 25, 50, 75 or 100 g m-2), and two application modes (dry and hydrated) in a completely randomized design with five replications. During the experimental period turfs were subjected to a period of 10 days without watering. For the sandy substrate, when subjected to water stress, there was linear increase on dry mater production of clippings (growth) in function doses of water-absorbent copolymer. The major dry mater of roots was achieved by application of the copolymer at a dose of 56 g m-2 hydrated. For the soil medium textured copolymer hydrated in doses 50-54 g m-2 water-absorbent copolymer showed greater production of dry mater of clippings of Bermudagrass cv. Celebration applied in powder and hydrated forms respectively. For medium textured soil this water-absorbent copolymer did not influence the intensity of green color, not the green coverage rate of the turfgrass. The application of hydrated copolymer reduced the dry matter of roots in the soil of medium texture. Keywords:  Hydrogel, Cynodon dactylon (L.) Pers, Maintenance, Turfgrass.  GODOY, L. J.

The results of studies on the effect of density, fertilizer and soil type on miscanthus productivity in Western Polesie are presented. It was found that the average yield of dry biomass of 15.5 t/ha was obtained on a dark gray loamy soil for a planting density of 20 pc/ha., and fertilizer application at the rate of N60Р200К200. The application of mineral fertilizers (N60Р200К200) on dark gray light-loamy and sod-podzolic sandy-sandy soil provided the highest increase in dry mass yield (up to control) of 2.9–3.4 t/ha. As the results of research have shown, the dry matter yield varies significantly under the influence of certain factors. Thus, in four years on average the highest dry matter yield was obtained on condition of planting density of 20 thousand pcs./ha and application of N60P200K200 on both dark gray light loamy soil and sod-podzolic sandy soil, 15.5 and 13.1 t/ha respectively. The lowest yields on two types of soils were obtained on condition of planting density of 10 thousand pcs./ha in the trial field without fertilizers (check) – 12.0 t/ha and 9.1 t/ha on dark gray loamy and sod-podzolic light sandy soils, respectively. The application of mineral fertilizers at the rate of N60P100K100 ensured increase in the yield by 1.8 and 2.2 t/ha of dry mass on two types of soils. Increasing the dose of phosphorus and potassium fertilizers up to 200 kg. d. r./ha contributed to an increase in the amount of dry mass to 15.0 and 10.1 t/ha compared to the trial field without fertilizers. The results of the research confirm the fact that with the increase in grain planting density and application of mineral fertilizers, the yield of miscanthus biomass increases, thus, the yield of solid fuel and energy increases as well. Consequently, the highest fuel yield of 17.1 t/ha with the energy yield of 271 GJ/ha was ensured by the application of mineral fertilizers at the rate of N60P200K200 and an increase in planting density to 20 thousand pcs./ha on dark gray light loamy soil. The lowest productivity at this density was characterized by the option without fertilizers (check) - 12.2 t/ha of dry biofuel and 194 GJ/ha of energy. Planting miscanthus plantations with the density of 15 thousand pcs./ha for four years on average reduced the yield of biofuel to 11.0 t/ha and energy to 175 GJ/ha in the trial field without fertilizers (check). However, the lowest amount of biofuel of 10.1 t/ha and energy yield of 159 GJ/ha was obtained in the trial field without fertilizers at the planting density of miscanthus of 10 thousand pcs./ha. The application of mineral fertilizers at the rate of N60P100K100 and N60P200K200 contributed to the increase of the above indices to 13.5 and 14.7 t/ha of dry biofuel and 215 and 235 GJ/ha of energy, respectively. Keywords: miscanthus, dry biomass, solid biofuels, energy, soil.

The work was developed in the experimental station of Embrapa Gado de Leite (Dairy Cattle Embrapa), in Coronel Pacheco, in Zona da Mata Region of Minas Gerais, with the purpose of evaluating the productive performance of Holstein cows kept on 'Coast-cross' (Cynodon dactylon (L.) Pears) pasture, fertilized, strategically irrigated and where the cows were daily supplemented with 3 or 6 kg of concentrate/cow/day. The data were collected during three years (October/2000 to October/2003), involving 108 lactations. An experimental randomized block design with two replicate areas per treatment was adopted, with nine animals per area and eighteen animals per treatment being utilized, with fixed stocking rate of five cows/ha. The system of grazing, under rotated stocking, with one day occupation of the enclosures (piquetes) and 25 and 35 days rest in the rainy and dry seasons, respectively was used. The pasture was irrigated in the months of lowest rainfall and fertilized with NPK broadcast at six applications/year. The availability of dry matter of the pasture was 7,280 kg/ha and 6,167 kg/ha in early grazing, with the post-grazing waste stubble of 4,885 kg/ha and 3,994 kg/ha, in the rainy (Spring/Summer) and dry (Fall/Winter) seasons, respectively. During part of the experimental period, a few morphogenic characteristics of the pasture were evaluated, recording availability of 83.9; 125.6 and 89.5 kg of DM of leaf blades/ha/day, on spring, summer and fall, respectively. The daily averages of milk production per cow were 15.57 and 18.80 kg/ day with 3.5% of fat and per area 77.80 and 94.00 kg/ha, when 3 or 6 kg of concentrate/cow/day were fed, respectively. It was concluded that supplemented and managed 'Coast-cross' pasture adequately enables high milk production per animal and per area, as quantitatively and qualitatively adequate for milk production.
