Based on links to reference material provided and additional referencing you have done, answer the following questions. Post your answers on the
Case Study: Rita found that fertilisers are applied to promote development of sugarcane.
Nitrogen requirement of sugarcane is greatest during the tillering (formative) phase. This is required for adequate tiller production and canopy development. Tillering in ﬁeld grown sugarcane commences around 30 to 45 days after planting. Therefore, adequate N supply should be made available to the crop in the soil from the start of the tillering phase. Further, crop requirement for N is higher in early grand growth period.
Need of sugarcane for phosphorus is greater in the formative phase of the crop. Thus, the optimum time of P application is during initial stages of crop growth. Therefore, sufficient P must be made available in the soil during formative phase for absorption by the crop.
Potassium applications are usually done along with N application. This is because of better utilisation of N by the crop in the presence of K; therefore, potassium should be applied along with N. However, late application of K at around six months has also been found to improve sugar recovery.
In general all the phosphorus should be applied before four months, nitrogen before six months and potassium before seven months period.
Q 1) For the crop selected by you what are the requirements to improve its productivity in terms of nutrient/ fertilizer requirement and application? (5 marks)
