The major climatic factors involved in potato production are heat and moisture availability. Heat availability across Manitoba will determine where potatoes will reach maturity as well as affect yields achieved in the potato growing regions of the province. Moisture availability will also significantly impact potential yields. In an attempt to describe these factors for Manitoba the following maps contain such information as occurrence of the last spring frost, occurrence of the first fall frost, length of the frost free period, p-day accumulations, growing season precipitation, crop water demand and crop water deficit. These maps have been derived from long-term weather data collected across Manitoba. Manitoba is located near the northern limit for agricultural production and as a result the occurrence of frost is one of the most limiting factors for crop development.

Areas susceptible to late spring frost also risk an early fall frost. The earliest average first fall frosts August 27 to September 1 are in the central Interlake, Riding Mountain and south-east regions of Manitoba. Likewise, the latest occurrence of first fall frosts from September 16 to September 26 are in those areas with the earliest occurrence of last spring frosts.

The frost free period determines the time available for crop production.

As such, it also determines what crops can be grown in a region. The average frost free period is the shortest near Riding Mountain at 75 days.

The longest average frost free period to days is in the Morden, Portage la Prairie and Selkirk areas. Potatoes possess very specific heat requirements.

From this information P-days can be calculated. The highest average accumulation of P-days, to , occurs in the very southern part of the Red River Valley, extending south of Dominion City through to Altona and northwest of Morden. There are also a few smaller areas to the east of and around Portage la Prairie, Selkirk and Great Falls. Most of the area to the south and east of a line from the southern end of Lake Manitoba to a point just to the west of Melita accumulates to average annual P-days.

The remainder of the province has fewer than P-days.

It is important to note that not all of the most southerly parts of the province have the highest P-day accumulations. For example, the area to the south and west of Melita does not have any more P-days than the area near Carberry, some distance to the north.

In fact, it is elevation and not latitude that seems to be the most important factor influencing P-days. Going west from the Red River along the U.


Both of these areas are at a higher elevation than nearby areas. At these locations, the fall frosts occur earlier, putting an end to the growing season, the date at which P-day calculations stop. One of the major factors in potato production is the seasonal soil moisture balance under a potato crop.

Several climatic and soil factors affect this balance, such as: The data presented here is based on calculations made for soil moisture status under a crop of corn as no such data is available for potatoes. Why not share! An annual anal Embed Size px. Start on.
