Abstract Seeds are a vector of genetic progress and, as such, they play significant role in the sustainability agri-food system. The current global seed market is worth USD 60 billion that expected to reach 80 by 2025. most often treated before their planting with both chemical and biological agents/products secure good quality high yield reducing or preventing losses caused diseases.

Maize is the most represented grain crop on world’s arable land. It mostly grown using standard sowing at an inter-row distance of 70 cm. However, growing in two rows (double-row sowing) increasingly common today. The aim this research was to determine influence different spatial distributions same population maize plants yield grains a larger range FAO hybrid maturing group. experiment lasted ...

Eight criteria have been established in the AgRISTARS Program to guide the evaluation and comparative analysis of crop yield models. The establishment of these criteria closely corresponds to the spirit of Dr. Hartley's ASA Presidential Address, particularly section three entitled "The Cooperation Between Statistician and Subject Matter Specialist" (1980). In our case the cooperation is between...

In northern Laos, rapid population growth and government policies to reduce the area under slash-and-burn systems have resulted in increased cropping intensity, which has increased weed pressure and reduced yields of upland rice. Promising alternative cropping systems include the use of weed-suppressing and multi-purpose legumes as short-term fallow crops. In this study, Stylosanthes guianensis...

INTRODUCTION World trade in agricultural commodities continues to grow. As agricultural trade expands, it increases the risk of introducing exotic insects into new areas where they may become plant pests. The establishment of new pests can be costly due to increased crop damage, control programs, and quarantine restrictions on trade. Quarantine or phytosanitary treatments such as cold, fumigati...

Switchgrass (Panicum virgatum L.) is an important bioenergy crop with the potential to provide a reliable supply of renewable energywhile also sequestering C in the soil. The purpose of this studywas to quantify CO2 fluxes during the establishment and early production years of a young switchgrass stand in the northeastern USA. Switchgrasswas sown in June 2004 and daily CO2 fluxesweremeasured fo...
