Rainfed pearl millet fertiliser dose nitrogen phosphorus recommendation for sandy loam soil.

For rainfed bajra a common recommendation is about 16 to 20 kg nitrogen and 8 to 12 kg phosphorus per acre, while irrigated or assured rainfall crops can take 32 to 40 kg nitrogen per acre. In dryland, apply full phosphorus and half the nitrogen at sowing as basal, and top dress the remaining nitrogen at around 25 to 30 days after sowing only if there is adequate soil moisture. Always base the exact dose on a soil test. Adding 2 to 3 tonnes of well rotted farmyard manure per acre before sowing improves moisture holding in sandy soils. Avoid heavy nitrogen if rains are failing, as it can cause lodging and waste money.
In Hisar I give one bag DAP at sowing and a top dressing of urea after the first good rain. If the monsoon is weak I skip the second urea, no point burning the crop. FYM every year keeps my sandy field from drying too fast.
Soil testing helped me a lot. I was overusing urea before. Now I split nitrogen and the crop stands better and does not fall in wind.
