1.10.2. Ideal Weather for Kharif and Rabi Seasons At the end of May or beginning of June, there should be some rainfall so that the fields can be ploughed. Towards the end of June, heavy rainfall is required for thorough wetting of the land. This must be followed by a period of clear sky for tillage and sowing operations. In the months of July and August, there should be periods of bright sunshine (not exceeding ten days) between two spells of rain. The weather in the month of September should be similar to that in July and August, but with less rainfall. A few showers at the end of September are needed to prepare the land for Rabi crops.
The first requirement for a good Rabi crop is that the soil temperature should fall rapidly to germination temperature. During November and early December, clear days and cool weather are beneficial. Towards the end of December, a light rainfall is useful. The winter rain must be broken by clear weather as continuous cloudy weather results in widespread plant diseases. The rest of the Rabi season should be dry and free from hailstorms.
