Confused when to start sowing kharif. How to use rainfall forecast for sowing decision.

Do not sow on the first shower, wait until the soil has received enough rain to ensure good germination, usually after the monsoon properly sets in over your area. As a thumb rule wait for adequate cumulative rainfall that wets the soil deeply rather than a single light spell, because sowing too early often forces costly re sowing if a dry spell follows. Use the IMD district agromet advisory issued twice a week, every Tuesday and Friday, through the Meghdoot and Mausam apps, which gives sowing, irrigation and spray guidance for your district and crops. Match the variety duration to the expected rains, keep seed and inputs ready in advance, and sow on the window your KVK confirms. Treat seed before sowing to handle early pests and diseases.
The year I sowed soybean on first rain and then it went dry, I lost the whole germination and had to buy seed again. Now I wait for the advisory and proper rain.
I check the Meghdoot bulletin every Friday before deciding spray and sowing. It is district specific so more useful than general TV forecast.
