Mustard crops are sown as winter crops on a large scale in Rajasthan. The area under this crop has grown very rapidly in the last few years. If ants are observed going out of their burrows during noon time, or soon after, it indicates the best time for sowing mustard seeds in the field. Since mustard plant is a very heat sensitive crop, it is normally sown in the first fortnight of the month of October, just at the beginning of winter. According to farmers, the presence of ants out in the open during noon time indicates a decline in the temperature due to onset of winter. Observe the movements of ants.
