Field Crops> Rape Seed and Mustard (Brassica spp.)> Manures and Fertilisers

Rape seed and mustard respond well both to organic and inorganic manures. If available, apply 15-20 tonnes of farm yard manure or compostal the time of field preparation. These crops show good response to chemical fertilisers. For good harvest, apply 60-90 kg nitrogen, 60 kg P₂O₅ and 40 kg K₂O per hectare. The quantity o' phosphorus and potash should be based on soil test recommendations. Split application of nitrogen has been found very useful for rape and mustard crop. Under irrigated conditions half of the nitrogen and full dose of phosphorus and potash should be applied as basal dose at the time of sowing by placement method. The remaining halt of the nitrogen should be applied at the time of iirst irrigation. If the crop is rainfed, use only half of the close of recommended nutrient. Rape seed and mustard have higher requirement for sulphur, therefore, nitrogen should preferably be applied through ammonium sulphate and phosphorus from single superphosphate. In rai, foliar app'ica-tion of nitrogen is useful uncier barani conditions.
