title: Soil resistance to penetration in cotton rows and interrows

description: ABSTRACT The soil physical quality is one of the most determinant factors for the development of any crop. This study aimed to assess the sample representativeness in soil resistance to penetration mappings taken in rows and interrows of the cotton crop, under two soil moisture conditions. Thirty control points were sampled in a cotton field of 91 ha. Soil resistance to penetration and soil moisture were measured at these georeferenced points. Regardless of soil moisture, the sampling position of soil resistance to penetration is indifferent (row, interrow, or in both positions) when the analysed depth is greater than 0.20 m in the cotton crop. The decrease of soil moisture causes the increment of soil resistance to penetration, regardless of the sampling position.

title: Nutrient contents and growth of corn fertigated with human urine and cassava wastewater

description: ABSTRACT This study aimed to evaluate the contents of macronutrients (NPK and S) and the growth of ‘Potiguar’ corn fertigated with human urine, cassava wastewater and their associations with NPK. The experiment was set up in greenhouse located on Campus I of Universidade Federal de Campina Grande. A completely randomized experimental design was used, consisting of eight treatments, corresponding to fertigation with mineral fertilizer NPK formula; organic, composed of yellow water, cassava wastewater and human urine associated with cassava wastewater; organomineral, composed of human urine associated with phosphorus and potassium, cassava wastewater associated with nitrogen and phosphorus and human urine associated with cassava wastewater and phosphorus, with five repetitions. At 50 days after sowing (DAS), plants were evaluated for the leaf NPK and S concentrations and growth variables: number of leaves, plant height, stem diameter, leaf area, fresh and dry mass of leaves, mass of stem and shoots. Nitrogen and phosphorus concentrations and the growth variables number of leaves, plant height, fresh and dry mass of leaves, mass of stem and of shoot were influenced by fertigation with human urine, cassava wastewater concentrations and their associations with NPK. In the leaves of corn cultivar Potiguar the accumulated concentrations of N, P and K, at 50 DAS, varied in the sequence N &gt; K &gt; P. Human urine has potential as source of N in fertigation of corn and cassava wastewater can be used if associated with other sources of nutrients.

title: Impacts of climatic changes on the vegetative development of olive cultivars

description: ABSTRACT The aim of this study was to simulate the vegetative development of the olive cultivars Arbequina and MGS ASC315 cultivated in Maria da Fé, MG, Brazil (22° 18’ 29” S, 45° 22’ 31” W, 1.276 m of altitude). The development of these cultivars was simulated in nine transplanting dates, considering three distinct scenarios for three periods (2011-2040, 2041-2070 and 2071-2100). Climate changes influence the olive crop management. The increase in air temperature modifies the development rate and the duration of the seedling phase of the cultivars Arbequina and MGSASC315. In colder months, there is accelerated vegetative development and shorter seedling phase duration. Conversely, in warmer months, there is delayed development with longer seedling phase duration.

title: Saline water on the leaf mineral composition of noni under organic fertilization

description: ABSTRACT Salinity is one of the main agricultural problems faced, and may negatively influence plant development. However, studies have shown that in protected environments and under the application of organic fertilizers, deleterious effects are mitigated. In this context, the objective of this study was to evaluate the effects of irrigation water salinity on mineral nutrition in noni plants grown in two environments and bovine manure application. The statistical design was a randomized block design arranged in split-split plot scheme, with five repetitions. The plots consisted of the cultivation environments (greenhouse and open field), the subplots formed by salinity levels of irrigation water (ECw: 0.3, 1.5, 3.0, 4.5 and 6.0 dS m-1), and the subsubplots were represented by the absence and presence of organic matter, with experimental unit consisting of three pots totaling 300 pots. The nitrogen, potassium, calcium, magnesium, sodium and chloride concentrations were determined in plant leaves. It was verified that the foliar concentrations of Ca2+, Mg2+, Na+ and Cl- and the ratio Na/K was increased with increasing salinity of the irrigation water, being the largest increments observed in the open field. Organic matter is not much relevant in attenuating the deleterious effects of irrigation water on the concentration of leaf nutrient in noni plants. The maintenance of lower values of Na/K ratio in the treatment with organic matter is a positive factor that can attenuate the effects of salt stress on cell metabolism.

title: Thermal comfort monitoring in aviaries by a real-time data acquisition system

description: ABSTRACT Thermal comfort inside broiler husbandry facilities is essential in obtaining good results in the production activity. Assessment of adequate thermodynamic conditions requires measurement and control, usually implying costs and specialized maintenance. The objective of this research was to monitor the temperature, relative humidity and air speed distributions by a developed low-cost, open-source and easy-to-use measurement system, using Arduino (hardware) and Scilab (software) for real-time data acquisition. Sensors were installed in a real facility (Cianorte, PR), with measurements for internal ambient (20 sensors for temperature/relative humidity, and two sensors for differential pressure, respectively 0.5 and 1.5 m high) and external ambient (pressure and wind speed, 1.5 m high). Data acquisition system has enabled communication with sensors which are easily read by the computer and stored in a data file. The developed data acquisition system proved to be efficient when applied in a commercial broiler husbandry facility, enabling real-time monitoring for thermal comfort parameters.

title: Temporal stability of soil moisture in banana cropping area in the Brazilian semiarid region

description: ABSTRACT Soil moisture is essential for agricultural production. Knowledge on its spatial-temporal variability is indispensable to support agriculture, and it is strongly influenced by cultural practices, soil cover conditions and irrigation methods. Thus, this study aimed to evaluate the temporal stability and spatial distribution of soil moisture as a function of the use of banana leaves as soil cover in a plot under conventional sprinkler irrigation and cultivated with banana in the Brazilian semiarid region. The study area was divided in two sectors, with and without covering using banana leaves. Soil moisture was monitored before and after irrigation, at 16 times, using FALKER HidroFarm sensors installed on a transect with 11 units spaced by 8 m, in each sector. The data were analyzed using descriptive statistics, temporal stability and Spearman correlation test. The morphology of the banana leaves and the irrigation system used contributed to lower soil moisture in the covered sector at all monitoring times. Variations in the physical-hydraulic properties of the soil promoted variations in soil moisture with the position of the sensors in the ground. The temporal stability technique allowed the identification of points that represent the mean behavior of soil moisture throughout the area. The use of banana leaf residues caused less soil wetting using sprinkler irrigation, indicating the need to pre-grind the material or use localized irrigation systems, practices that are not very accessible to small farmers.

title: Rooting of sweet potato seedlings submitted to supplemental calcium and phosphorus nutrition on substrate

description: ABSTRACT The objective of this study was to evaluate the rooting and growth of sweet potato seedlings in trays in response to substrate supplementation with calcium (Ca) and phosphorus (P). Two greenhouse experiments were conducted in a randomized block design with a split plot scheme and eight repetitions. In the Ca experiment, the plots were the doses of 0, 100 and 200 mg kg-1 of Ca, and in the P experiment, by the doses of 0, 150 and 300 mg kg-1 of P. In both experiments, the subplots corresponded to the sampling time of seedlings (15, 30, 45, 60 and 75 days after planting). The Ca present in the substrate was sufficient to promote the proper rooting and growth of sweet potato seedlings in the trays. The Ca supply in excess (200 mg kg-1) adversely affected the growth of seedlings that remained in the tray for more than 60 days. Although the seedlings supplied with P showed higher root growth rate after 45 days, the initial P available in the substrate was sufficient to promote the adequate growth of the seedlings in the trays until 60 days.

title: Physico-chemical characteristics of passion fruit flour under removal of flavedo and of maceration

description: ABSTRACT Passion fruit has the peel (albedo and flavedo) as its major component and it can be used in the production of flour as source of nutrients and enrichment of food products. Thus, this study aimed to evaluate the production of flours from passion fruit albedo and whole peel, verifying the influences of flavedo removal and maceration, as well as the variation in drying temperature (70 and 80 °C) on the physical and chemical characteristics of the flours. The flours has a light color with slight trend to red and stronger trend to yellow. Moisture content is within the limits established by the current norms of ANVISA (a maximum of 15%). The flavedo removal contributed to the increase of water, crude fiber, neutral detergent fiber and acid detergent fiber concentrations. However, it reduced moisture, ash, protein, lipids and carbohydrates concentrations. On the other hand, the maceration decreases luminosity, lipids and carbohydrates and increases the chromaticity a* and b* and moisture in the flours. In relation to the increase in temperature, a decrease was observed in the protein concentration and an increase in the concentration of ash and lipids. Based on centesimal composition, the flour should be prepared with whole peel without maceration and dried at 80 °C.

title: Productive traits of rye cultivars grown under different sowing seasons

description: ABSTRACT This study aimed to adjust the Gompertz and Logistic nonlinear models for the fresh and dry matter of aerial part and indicate the model that best describes the growth of two rye cultivars in five sowing seasons, as well as to characterize the growth of the cultivars regarding the fresh and dry matter of aerial part. Ten uniformity trials were conducted with the rye crop in 2016. A weekly sampling and evaluation of 10 plants per trial was performed from the time the plants presented one expanded leaf. For each plant, the fresh and dry matter of aerial part were weighed. The Gompertz and Logistic models were adjusted to the accumulated thermal time based on the measures of each trait in each assessment. Also the parameters a, b, and c for each model were estimated and calculated the interval of confidence for each parameter, as well as the inflection points, maximum acceleration, maximum deceleration and asymptotic deceleration. The quality of the model adjustments was verified using the coefficient of determination, Akaike information criterion, and residual standard deviation. The intrinsic nonlinearity and nonlinearity of the parameter effect was quantified. Both models satisfactorily describe the behavior of the fresh and dry matter of aerial part. The Logistic model best describes the growth of rye cultivars. The growth of the cultivars BRS Progresso and Temprano is distinct between sowing seasons. Cultivar BRS Progresso requires a lower thermal time until reaching 50% of its growth when compared to the Temprano cultivar.
