Three catch crop species, ryegrass, forage rape and black oat, were grown between successive rotations of maize to reduce nitrogen leaching due fertilization with digested dairy manure. Catch crops showed a high nutrient uptake, but wide range, depending on the year specie. Ensiling was shown be feasible storing method increasing methane production per hectare 14–36% compared fresh crop. In sem...

Background: Ever increasing global population requires to find additional options or increase the efficiency of food and feed supply to fulfil its dietary needs. In agricultural sector, competing situations with energy supply occur and ask for more sustainable solutions in an ethically correct manner. Methods: The Sustainable Process Index (SPI) provides a powerful method for an ecological eval...

The wild species field cress (Lepidium campestre), belonging to the Brassicaceae family, has potential to be developed into a novel oilseed- and catch crop, however, the species needs to be further improved regarding some important agronomic traits. One of them is its low oil content which needs to be increased. As far as we know there is no study aiming at increasing the oil content that has b...

This study identified statistically significant, and practically important, seasonal pheromone trap response dynamics of Euschistus conspersus (Uhler) in processing tomatoes in 12 fields over 5 years in California, USA. Commercial fields were monitored weekly using traps baited with Euschistus spp. pheromone and direct canopy shake samples. Regression analysis determined no significant relation...

The complexity of assessing the irrigation performance a solid-set sprinkler system implies analyzing factors features, spacing among sprinklers, evaluation heights, meteorological variables and crop. In this research, number experiments with impact sprinklers were evaluated different operating conditions models uniformity (CUC) losses due to drift wind (WDEL) assessed at catch-can heights. Sta...
