leach into groundwater after crop harvest in the fall, and depending on the species, can sequester atmospheric C Biculture legume–cereal cover cropping may enhance aboveand and/or N, thereby reducing the amount of N fertilizer belowground biomass yields and C and N contents. The increase in C and N supply to the soil has the potential to improve soil quality required for summer crops (Hargrove,...

Little is known about the long-term contribution of cover crops to weed management in tillage- and herbicide-based systems. Do mainly filter species capable setting seeds during fallow period? Can crop biomass productivity explain differences suppression among species? Does reduced seedbank density translate into lower higher productivity? Soil samples (0–15 cm) were collected 2018 after termin...

Two experiments were conducted in north-central Florida to examine the effects of various winter cover crops on plant-parasitic nematode populations through time. In the first experiment, six winter cover crops were rotated with summer corn (Zea mays), arranged in a randomized complete block design. The cover crops evaluated were wheat (Triticum aestivum), rye (Secale cereale), oat (Avena sativ...

Grass and legume mixtures work well, but there are no data on the mixed planting of desho grass (Pennisetum glaucifolium) Vicia species. A study was conducted to investigate whether forage dry matter yield (DMY) quality can be improved by growing species in with grass. The experimental layout followed a randomized complete block design four replications, where treatments consisted pure stands t...

in order to study the effects of different sowing dates by some of companion crops on the weeds control, morphological traits and yield of corn sc 504, a field experiment was carried out of research field at tabriz university during 2010 growing season. treatments were arranged in a factorial experiment using randomized complete blocks design with three replicatins. factors was include four lev...
