1180. Campbell, C.A., R.P. Zentner and P.J. Johnson. 1988. Effect of crop rotation and fertilization on the quantitative relationship between spring wheat yields, available soil moisture, and precipitation.. Canadian J. Soil Sci., 68(1):1-16.
The effects of crop rotation and fertilization on the quantitative relationship between spring wheat yields, available soil moisture, and growing season precipitation were determined. Stubble-seeded wheat required 68 mm of moisture to produce the first kilogram per hectare of grain; fallow-seeded wheat required about 46mm. The lower threshold level of MU for grain production decreased from about 140mm to the values cited above; this has resulted in substantially greater moisture use efficiency in recent years likely due to better, more timely crop mangement and the improved cereal varieties.
3825. Lafond, G.P. and D.B. Fowler. 1989. Soil temperature and moisture stress effects on kernel water uptake and germination of winter wheat.. Agron. J. 81:447-450..
Direct seeding of wheat into standing stubble in Saskatchewan is often done into dry soil. This study examined the importance of soil temperature and moisture potential on kernel water uptake and germination, so that the minimum requirements for successful crop establishment could be identified. The effects of temperature on speed of germination were much larger than those of moisture, indicating that seeding of stubbled-in winter wheat should proceed at the optimum date regardless of seedbed moisture conditions.
