Crop heat units (CHU) are commonly used to rate suitability of corn (Zea mays L.) hybrids and soybean [Glycine max (L.) Merrill] varieties for production in various regions of Canada.

Recent interest in corn (Zea mays L.) production among forage producers in Newfoundland, Canada, raises questions of risk, scale and impact of seasonal heat accumulation for attaining objectives of this paper were to present the results of corn performance in a short-term trial at three selected sites (St.

John’s, Deer Lake and Stephenville), calculate corn heat unit (CHU Cited by: However, this system has not been widely accepted in the Atlantic region of Canada (the maritime provinces), where lack of corn ma- turity at harvest due to cool and short growing seasons is one of the major limiting factors to corn production (Atlantic Field Crops Committee, a).Cited by: As growing degree-days are most often used to evaluate heat conditions for cool season and overwintering crops and crop heat units are more suitable for warm season crops, the following analyses are focused on EGDD for overwintering crops and CHU for warm season by: needs of a corn plant.

The rate of growth of the plant increases with increasing temperatures. Corn heat unit accumulation begins on May 15 and ends on the date of the first fall killing frost with temperatures below -3 C. The corn heat unit calculation assumes that no growth occurs when night temperatures are below C or day temperatures below 10 Size: KB.

A CHU is a measure of the heat accumulated over the growing season specific to the physiological needs of a corn plant. The rate of growth of the plant increases with increasing temperatures. Corn heat unit accumulation begins on May 15 and ends.

Crop (corn) heat units Crop heat units (CHU) are based on a similar principle to growing degree days. CHUs are calculated on a daily basis, using the maximum and minimum temperatures; however, the equation that is used is quite different. The possibilities to determine the maturity ratings of corn hybrids by using the heat units method are discussed.

Emergence is assumed to be the starting point of the cycle for the heat units calculation; in view of a more exact evaluation of the development behaviour of an hybrid, two different periods are considered: from emergence to silking (flowering index) and from silking to Author: E. Desiderio, M.

The Corn Heat Unit Program (CHU) is a weather-based program that insures against a lack of corn heat units for corn acres over the growing season. This program provides a risk management option to silage, grazing and grain corn producers. For corn, especially for hybrids, 27 kg of nitrogen (N), kg of phosphorus and 20 kg of potassium (K) are needed to produce a metric ton (1, kg) of corn grain per hectare.

This means that a 5-ton grain yield target will need about kg of N, kg of P and kg of K per hectare. Field trials were conducted at five locations in the Atlantic region of Canada over seven years to determine relationships between climate and corn (Zea mays L.) maturity.

Ear moisture at harvest was correlated with Corn Heat Units (CHU), growing degree-days above 10 deg C and soil temperature (r('2) = toP is equal to or less than 0.

The GDD estimation method most commonly used throughout the U.S. for determining heat unit accumulation relative to corn phenology was first evaluated by Gilmore & Rogers (Corn typically requires to growing degree days (GDDs) to emerge (but emergence requirements can vary from 90 to GDDs).

To determine daily GDD accumulation, calculate the average daily air temperature (high + low)/2 and subtract the base temperature which is 50 degrees F for corn.
