Non-Peer ReviewedThe effect of temperature and precipitation on the yield and quality of Tobin canola has been determined by a statistical method known as regression analyses. The equations obtained from this analyses were used to show how an increase in maximum temperature in the growing season reduced yield, increased protein, decreased oil content and decreased time to maturity. The equations, also, showed that increased rainfall increased yield, decreased protein, and increased time to maturity. Lower minimum temperatures were associated with higher chlorophyll content of seed. The information could be used by farmers and researchers as an index of suitability of either Polish (Brassica rapa L.) or Argentine (Brassica napus L.) cultivars for production areas in the Province
