Weed management in irrigated fenugreek grown for forage in rotation with other annual crops

Weed Control with Cover Crops in Irrigated Potatoes

Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...

Soil nitrate testing supports nitrogen management in irrigated annual crops

Soil nitrate (NO3) tests are an integral part of nutrient management in annual crops. They help growers make field-specific nitrogen (N) fertilization decisions, use N more efficiently and, if necessary, comply with California’s Irrigated Lands Regulatory Program, which requires an N management plan and an estimate of soil NO3 from most growers. As NO3 is easily leached into deeper soil layers ...

Shallow groundwater quality on dairy farms with irrigated forage crops.

California's dairies are the largest confined animal industry in the state. A major portion of these dairies, which have an average herd size of nearly 1000 animal units, are located in low-relief valleys and basins. Large amounts of liquid manure are generated and stored in these dairies. In the semi-arid climate, liquid manure is frequently applied via flood or furrow irrigation to forage cro...

Developing heterotic groups for hybrid breeding in crop plants with emphasizing on forage crops

Exploitation of heterosis in hybrid breeding and development of synthetic cultivars is an essential procedure in plant breeding programs. The main goal of hybrid breeding programs is to select desirable parental genotypes to maximize the expression of heterosis. However, since development of high yielding hybrids and synthetic cultivars are costly and time-consuming, the accurate prediction of ...
