Studies on crop-weather relations in cassava varieties were carried out for three plantings viz., May, October and December at Agronomy farm, College of Horticulture, Vallanikkara. Four varieties of two short-duration, (VellayaniHraswa and SreeVijaya) and two normal- duration varieties, (M4 and SreeAthulya) were grown under rainfed conditions. The result revealed that variety SreeAthulya was the high yielder for all the three plantings but was on par with M4 and SreeVijaya for May planting. However, cyanogenic glucoside content was found to be higher for SreeAthulya. The most ideal month for planting was found to be May, followed by October. Correlation studies with yield and weather parameters suggest that the yield influencing weather parameters at early crop establishment period were maximum temperature, minimum temperature, rainfall and relative humidity, placing the most promising varieties as SreeVijayaand M4. From this study it was also concluded that May planting was the most ideal month of planting cassava, followed by October planting.
