Environment protected with sombrite screen as an alternative to control fruit f...

Fruit fly is the main pest of plum trees. This study aimed to evaluate the production and damage caused by fruit fly in protected cultivated plum with screen, unprotected and conventional with insecticide. Nine 'Fortune' plum plants were used: three control plants (without screen and without insecticide); three plants wrapped laterally by sombrite 70% screen with 5 m of high; and three plants with conventional ...

Sensitivity of common bean accesses to water stress

This study aimed to characterize agronomically landraces and commercial  genotypes for tolerance to drought stress and investigate the effect of water stress on the agronomic traits of interest. In Rio Grande do Sul, beans are grown from August to April, when water stress is usually observed. First, 25 bean genotypes (19 landraces and 6 commercial varieties) were characterized in the field. Then, the genot...

Interactions between nitrogen fertilization with the growth and leaf macronutri...

Rootstocks of ‘Rangpur’ Lime and ‘Swingle’ Citrumelo were grown in containers with substrate in a greenhouse, aiming to evaluate the effects of N (urea) fertilization on the vegetative growth and macronutrient content of the plant tissue. The experimental design was a factorial randomized block design with four repetitions, and each experimental plot was composed of five plants. Four doses of N (0, 2.0, 4.0 and...

Agricultural production of the family farming of Roque Gonzales

The Brazilian rural territory is marked by the large number of family farming establishments, which are responsible for much of the food production. The objective of the article was to verify the agricultural and livestock production of the agricultural establishments of the family farming in the municipality of Roque Gonzales, state of Rio Grande do Sul, of the agricultural-harvest year of 2016-2017. The resea...

First report of Megastigmus brasiliensis occurrence parasitizing eucalyptus gal...

The eucalyptus gall wasp (Leptocybe invasa) causes severe damage to its host plants. One of the main strategies to control its dispersion is biological control with parasitoid hymenopterans. Some parasitoid species, like Megastigmus brasiliensis, may have potential in the biological control of gall wasp in the southern region of Brazil. The study aimed to report the occurrence of parasitoids associated with L. ...

Luminosity and temperature on pecan seed germination

The objective of present work was to evaluate the effect of luminosity and temperature on Carya illinoinensis germination seeds. In order to standardize imbibition process, seeds were previously submitted to scarification process. The experimental design was completely randomized, arranged with a 3x4 factorial scheme, in which were tested three luminosity regimes (absence of light, continuous light and alternat...

Effects of cuniculture commercialization on household poverty status in south w...

This study evaluated the effect of Cuniculture commercialization on household poverty in Osun State, Nigeria. Descriptive and inferential statistics of frequency counts, Foster-Greer-Thorbecke (FGT), Household Commercialization Index (HCI) and Tobit Regression was used to analyze data collected from 120 respondents randomly selected from the register of Rabbit Farmers and Breeders Association of Nigeria (RFABAN...

Influence of the storage in common bean nodules weight

Biological nitrogen fixation (BNF) is one of the main topics to be researched in beans. However, studies evaluating the inherent FBN characters such as the number and weight of nodules require more timeconsuming since the nodes viability of the plant after being collected is short. The objective of this study was to evaluate the effect of different storage conditions and containers of bean nodules. The treatmen...

Antioxidants as nutraceuticals to mitigate oxidative stress in bees: systematic...

Food production on large scale has led to an expansion in the use of pesticides. An important process in this dynamic is the pollination, carried out by bees, which is affected by the use that of these products considered stressors of the metabolism of these arthropods. Given these facts, the objective of this review was to verify whether the use of antioxidants in supplementing bee feeding can mitigate the oxi...
