The combined factors of financial and food security, a rapidly increasing population and the associated requirement for food generated sustainably in a changing environment have brought food swiftly to the top of most government agendas. The consequence of this is that we need to produce more food at an equivalent or higher quality with lower inputs. These aims are achievable using conventional...

A strict field experiment with crops sown in crop rotation and monoculture wascarried out in the years 1988-2012 at the Experimental Station Uhrusk belonging tothe University of Life Sciences in Lublin, south-eastern Poland. The study wasaimed at evaluating the structure of weed communities occurring in crop rotationand monoculture of cereals. The highest weed density m-2 was determined inthe s...

A field experiment was conducted to evaluate the yield and chemical composition of triticalegrain in different crop rotation and tillage systems. The first experimental factor was thecropping system – a) crop rotation and b) monoculture and the second factor was the tillagesystem – 1) conventional (CT), 2) reduced (RT) and 3) no-tillage (NT). The spring triticale yieldwas found to be 15.4% high...

The largest corn yeld in Brazil is currently the second harvest, which most susceptible period to climatic adversities occurring during cycle. Thus, introducing beneficial elements for maintaining adequate development of plant can help producers obtaining greater kernel yields. Among studied elements, nicotinamide has potential use since it associated with accumulating secondary metabolites and...

Invasive, polyphagous crop pests subsist on a number of crop and non-crop resources. While knowing the full range of host species is important, a seasonal investigation into the use of non-crop plants adjacent to cropping systems provide key insights into some of the factors determining local population dynamics. This study investigated the infestation of non-crop plants by the invasive Drosoph...

The present study aimed to evaluate the influence of fertilization formulated at planting and doses nitrogen in topdressing on yield components second-crop corn. experiment was conducted between March June 2018 farm State University Goiás, Unit Ipameri-GO. randomized block design, arranged a 3 x 5 factorial scheme with four replications, used. Three fertilizer formulations (06-22-12; 08-20-15 0...
