Diagnosis of Phosphorus Deficiency in Rape and Remedial Measures
Rapeseed is a phosphorus-producing crop, and its demand for phosphorus is more than double that of cereal crops. In the absence of phosphorus, the plants are short, with slow growth, delayed leaf emergence, small leaf area, dark green leaves, lack of luster, purplish red spots or patches on the edges, leaf veins on the back of leaf petioles and leaves turning purple; poor root development. The number of pods and 1000-grain weight significantly decreased, and the oil yield decreased. Remedial measures: Phosphorus deficiency at the seedling stage, with 20-25 kg of superphosphate per acre to chase or pour water, the sooner the effect is better; later with a 1% solution of superphosphate calcium foliar spray.
