Various weather factors arbtried and the following tentative conclusions are draw An optimum of about 16°C minimum temperature, 29-3°C maximum temperature and 22° to 23°C mean temperature with 60 to 65 hours of bright sunshine per week and 50 to 60 per cent humidity appear to be the most favourable condition for wheat "in Dharwar. An optimum total water requirement may be assessed as equivalent of 40 to 50 cm of rainfall during the period July to the. end of the vegetative phase.
