The aim of this study was to evaluate the growth, yield and nutrients uptake in lettuce with winery and poultry rearing waste as organic fertilizer. The winery waste was composted, while the poultry rearing waste was submitted for a thermic process to obtain a nutrient solution used in fertirrigation. The treatments were composed by different concentrations of plants organic fertilizer: T1, without fertilizer; ...
The occurrence of diseases is the main reason for reduction in common bean production in Brazil. Fusarium oxysporum f.sp. phaseoli and Sclerotinia sclerotiorum are the causative agents of important diseases of this crop. For the biological control to be successful for these and other diseases, the knowledge of the metabolites produced by the biocontrol agents such as Trichoderma spp. Is essential. From this poi...
The covers can be used on fruits and vegetables in natura, because modifying the atmosphere around those avoiding physical and chemical changes. Thus, the present study aimed to evaluate the effect of filmogenic solution based on chitosan conservation at different times and temperatures of apples cv. Fuji. In addition to assessments rot incidence and qualitative changes the deposition surface was visualized in ...
The physical and mechanical soil quality is crucial for food production and inadequate management can lead to loss of sustainability and reduced productivity. The aim of this study was to determine the physical and mechanical properties of a Rhodic Kandiudox under different land use systems. The study was conducted in the experimental site of the Universidade do Oeste de Santa Catarina, in São José do Cedro, SC...
Considering the pharmacological importance of oregano (Origanum vulgare L.) and peppermint (Mentha piperita L.), the development of in vitro propagation and cultivation forms may contribute to the insertion of these species into sustainable production systems with preserved genetic characteristics. The objective of this work was to verify the type of explant most promising for the in vitro establishment of oreg...
A study was conducted with the objective of evaluating the seminal characteristics of the Geophagus brasiliensis kept in captivity with and without hormonal induction. For that, 26 males were distributed among the following treatments: nine males without hormonal induction; nine males with hormonal induction of carp hipophysis extract (HC) and eight males with hormonal induction by human chorionic gonadotropin ...
The study aimed to analyzed the vegetation from NDVI (Normalized Difference Vegetation Index) dynamics in Eucalyptus dunnii and Eucalyptus Urograndis comparing the NDVI generated from the digital numbers obtained from the conversion to apparent reflectance. The satelite images of TM/Landsat 5 sensor was used. Converting digital numbers (DN) to reflectance values and the calculation of the NDVI were obtained thr...
The olive tree (Olea europaea L.) cultivation has intensified in the state of Rio Grande do Sul, which today has more than 3,500 hectares planted and 145 farmers, being the largest producer in the country. However, olive growers still face a number of difficulties, including those of plant breeding, especially those related to pest and disease management. The objective of this work was to generate basic and app...
Native from Rio Grande do Sul natural pastures, Trifolium argentinense Speg. has sexual reproduction through aerial and subterranean seeds (amphicarpy) and vegetative reproduction by regrowth from storage roots. In this study the seeds produced at the soil-surface flowers, the depth effect and scarification on the aerial and subterranean seeds germination and the storage roots produced by plants derived from th...
The olive tree (Olea europaea L.) even though has both hermaphrodite and staminate flowers, it has mechanisms favoring the allogamy, being not advisable the monovarietals orchards planting. The pollination of olive trees is anemophilous, and produce a large amounts of pollen grains, dispersed throughout the atmosphere during the bloom. The economic viability of the olive oil is dependent of the fruit production...
