Brazil stands out before other countries for having a gigantic area for food production. Paraná is the state that stands out among the nation's states with its gross production value (VBP), which in these values are the agricultural and livestock productions such as poultry farming. Moreover, Paraná stands out for having a high solar irradiation, which leads rural entrepreneurs to seek the use of renewable energies as electric energy, especially photovoltaic energy. With that, the present study refers to a qualitative systematic review, whose objective was to conduct an analysis of the scientific production on the panorama of solar photovoltaic energy in poultry farming in the state of Paraná, in the period from 2012 to 2021. The bibliographical search was carried out in the databases: Scopus and Scielo including others described on the theme, searching for information from government agencies responsible for production indicators, growth and development. This review showed that the State of Paraná has a great potential for photovoltaic solar energy generation, by the levels of solar radiation which is inserted and also for having the largest poultry herd in Brazil.

Organomineral fertilizers are fertilizers of organic origin enriched with mineral nutrients that have been presenting positive responses in several vegetable groves. The aim of this work was to use the experimental factorial design methodology 3 2 and response surface analysis to verify the influences of the variable productivity of the arugula var. Folha Larga. Vegetation® and Spin® foliar fertilizers were applied in factorial design 3 2 , with three repetitions at the central point. The results of this research lead us to affirm that the central point (test 6) with application of 60 mL L -1 of the Vegetation® leaf fertilizers associated with Spin® obtained higher values for the productivity of arugula var. Folha Larga relative to the control.

The main objective of this work was to evaluate the effect of the consortium of carrot and radish crops on the efficient use of land. The experiment was developed in the vegetable production area of the Adroaldo Augusto Colombo State Agricultural College in the period from March to June 2019. Three repetitions were performed from the randomized block experimental design. The treatments refer to radish monoculture, carrot monoculture, and consortia of carrot with radish, placing one row of each crop and
