Organic acids Effective alone or on combination with other sanitizers, simple products such as lemon juice or vinegar may be used Not useful for all products, may have adverse effects on sensory qualities, may lead to loss of germination percentage when used on seeds... 

You can also sterilize seeds with heat by immersing them in hot water. Take care if you use this method. Excessive heat can kill seeds and will usually reduce germination percentage. It s safer to use a large quantity—several gallons—of water to minimize the possibility of a sudden surge in temperature. 

To calculate the number of plants of a given type (susceptible or resistant) in the fall of year n, start with the number of seeds at the beginning of the year, multiply by the germination percentage, by the fraction of germinated seeds that become established, and by the fraction that survives through the summer, obtaining...

A novel corn seed coating agent (NCSCA) was prepared by modifying chito-san, a natural nontoxic biopolymer, trace elements and fertilizer seed treatment which resulted in a high germination percentage and yield in corn, and also showed high resistance to head smut caused by Sphacelotheca reiliana stress both under laboratory and field conditions [48].

An increasingly important pest of bean seed crops is the bean beetle or brachid beetle (Bruchus rufimanus), the larva of which burrows neat circular holes into the near ripe seed which, after combining, can provide a refuge for weed seeds such as wild oats, and may, if infestation is greater than 10% of seeds, adversely affect the germination percentage. Approved insecticide applications to the crop when adult beetles can be found have become common in order to reduce the levels of this pest. 

Thousand seed weight and germination percentage may be obtained from the seed merchant. 

Coated seed is drilled with a precision drill, i.e. Stanhay or Mini Air (Fig. 17.6) into a moist seed bed. Seed rate will depend on the germination percentage and field conditions at sowing and the desired size of carrot at harvest. Seed rate...
