The data of long-term research on increasing the yield and quality coriander seeds by selecting most productive varieties improving basic techniques its cultivation technology are presented. It has been established that is Akkord cultivar, which we have bred released. Biochemical, biological agrotechnical features studied. High laboratory germination was revealed (90.1%), field varied from 88.5...

The dynamics of soil moisture and its temperature is an important criterion for evaluating tillage technology in terms achieving plant production stability. Understanding changes depending on rainfall air necessary to develop application models agriculture 4.0. A hypothesis was adopted assuming that the thermal properties will depend cultivation. Hence, aim research learn during a growing seaso...

Winter road maintenance planning involves a variety of decision-making problems related to the routing of vehicles for spreading chemicals and abrasives, for plowing roadways and sidewalks, for loading snow into trucks, and for transporting snow to disposal sites. These problems are very difficult and site specific because of the diversity of operating conditions influencing the conduct of wint...

The interaction between millet and European corn borer, Ostrinia nubilalis (Hübner), was investigated to gain insight into whether millet could serve as a refuge or trap crop for O. nubilalis management. In 1995, 1996, and 1999, millet selection studies were conducted in North Dakota and New York with four millet species. Proso millet, Panicum milliaceum L., had the highest infestation and wide...

This experiment was conducted, to study the effect of planting time and planting density on savory (Satureja sahendica Bornm.) in 2012 in Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was carried out in split plot in time in the form of a randomized complete block design with three replicates. The main plots were planting times in two levels ...

Long-term assessment of NO3-N leaching losses to subsurface drainage "tile" water from different tillage systems and N application rates can help mitigate the environmental concerns of production agriculture. A three-phase field study was conducted to investigate the impact of two tillage systems (chisel vs. no-till) and different N application management systems on flow-weighted NO3-N concentr...

Irrigated crops are produced on 645,000 ha in east-central Washington and northcentral Oregon (1). Approximately 70% of this cropland is irrigated with water diverted from rivers, while water for the remaining hectares is pumped from deep wells. Much of the irrigated cropland is found in areas of less than 200 mm annual precipitation, where dryland farming is difficult or impossible. Wind erosi...
