Integrating alfalfa (Medicago sativa L.) with corn (Zea mays L.) for grain will increase biodiversity, reduce the negative environmental impact of corn monoculture and increase farm profitability. The objectives of this research were to evaluate forage productivity and nutritive value, along with stand establishment of alfalfa in a corn grain syste...

The aim of this study was to verify the response of 13 American asparagus cultivars cultivated for green spear on surface postharvest drip irrigation. Irrigation, used to compensate for periodic deficiencies in precipitation, allows for high- and good-quality crops for many species. The field experiment was carried out in 2006–2008 on a very light...

Weather conditions regulate the growth and yield of crops, especially in rain-fed agricultural systems. This study evaluated the use and relative importance of readily available weather data to develop yield estimation models for maize and soybean in the US central Corn Belt. Total rainfall (Rain), average air temperature (Tavg), and the difference...

Climate changes lead to a rise in air temperature, which significantly increases the water needs of plants. Maintaining crop productivity will increasingly require the use of plant irrigation. The aim of this study was to assess the water needs of grapevines cultivated in the western provinces of Poland. The calculations were made on the basis of t...

The effect of nitrogen fertigation of two watermelon cultivars grown on the very light soil in the central part of Poland, during 2012–2014, was evaluated. The field experimental design was a split-plot with four replications. The main plot was the drip fertigation with nitrogen applied in two combinations: drip irrigation + broadcasted nitrogen fe...

The nutritional value of carrot is determined by the content of total sugars and monosaccharides, carotenoids and vitamins, including vitamin C, in its roots. In 2009-2011, field experiments were carried out concerning the effect of biostimulating preparations applied during the carrot vegetation period on selected nutrients of its roots (total sug...

Neonicotinoids are the most widely used insecticides worldwide and are typically deployed as seed treatments (hereafter NST) in many grain and oilseed crops, including soybeans. However, there is a surprising dearth of information regarding NST effectiveness in increasing soybean seed yield, and most published data suggest weak, or inconsistent yie...

Intercropping winter cereals into Kura clover (Trifolium ambiguum M. Bieb.) has the potential to improve forage nutritive value without reducing yields. The objective of this research was to compare forage yield and nutritive value of cereal–legume mixtures to cereals or Kura clover grown in monoculture and harvested at two different maturity stage...

Soybean [Glycine max (L.) Merr.] produces a high-quality protein that provides an appropriate balance of amino acids for monogastric animals. It has been reported that the relative abundance of some essential amino acids may be reduced in soybean with high protein concentration. A dilution of essential amino acids in soybean protein would lead to a...

Agriculture in the Midwest region of the United States is based on intensive corn (Zea mays L.) production that provides food, feed, and fuel. Crop rotation is a vital management option for improved yield and environment preservation.Three rotation systems—continuous corn (CC), corn–soybean (Glycine max [L.] Merr.; CS), and corn–soybean–wheat (Trit...

The effect of post-harvest irrigation and genotype on the quality components of white asparagus spears was investigated. The field experiment was conducted in 2003-2008 on a very light soil in the Bydgoszcz region. The research was based on a two-factorial split-plot design with randomly selected sub-main blocks. The first studied factor was irriga...

In response to climate change, there is a need to adopt more resilient cropping systems for increased productivity. In this study, three corn (Zea mays L.)-based rotations-continuous corn (CC), corn-soybean (Glycine max [L.] Merr.; CS), and corn-soybean-wheat (Triticum aestivum L.; CSW), where all residues were retained on the field after harvest-w...

W USA lucerna zajmuje wśród roślin rolniczych czwarte miejsce pod względem powierzchni uprawy. Hodowla nowych odmian ma na celu zwiększenie odporności na patogeny i suszę, a także poprawę jakości paszy przy zachowaniu wysokiego poziomu plonowania. Na etapie testów jest genetycznie modyfikowana (GM) odmiana lucerny o obniżonej zawartości lignin. Dos...
