Nitrogen should be applied in 3 splits, 25% as basal, 50% at 3 weeks and 25% at 6-7 weeks stage.
In acid soil apply 1-2 tonnes lime/ha at the time of 1st land preparation (15 days before sowing).
Top dressing of fertilizer should coincide with hoeing/ inter culture and earthing up operation so that the fertilizer can be incorporated into the soil.
Placement of manures and fertilizers in the furrows before sowing and ensuring that the seeds do not come in contact with fertilizers give better results. For top dressing place fertilizers on the side along the rows after hoeing or interculture and then earth up.
