The same wheat development note that xes the optimum temperature for the crop has also to state the ideal minimum temperature, since the sowing date advised to the borrowers of the district is chosen so that the crop passes its vegetative phase in that band. The note observes that wheat is not injured by a low temperature at that stage but is actually favoured by it, tillering more freely and building a larger root system, and that a crop sown too early misses the band altogether and runs to ear on a small frame. The technical cell has warned that the gure entered must be a minimum well above the freezing point, since a temperature at or below zero at the ear emergence stage causes sterility and is a hazard rather than an ideal. The ideal minimum temperature for the wheat crop is
