THE EFFECT OF WINDROWING HARD RED SPRING WHEAT AT DIFFERENT STAGES OF MATURITY AT FOUR LOCATIONS IN WESTERN CANADA

Abstract
Hard red spring wheat (Triticum aestivum L.) cv. Neepawa was windrowed at kernel moisture contents (KMC), wet basis, ranging from about 45 to 14% for 3 yr at four diverse locations, from 50° 16′ to 55° 12′ N latitude, in western Canada. Compared with windrowing at lower KMCs, cutting the crop at 35% KMC did not cause significant loss in seed yield or quality as measured by test weight (kg/hl), 1000-kernel weight, or percent protein. The results show that cutting wheat at 25–35% KMC can be recommended as a general practice throughout the wheat-growing region of the Canadian Prairies.
