Hoshiarpur - On the appeal of Punjab Agriculture University to use other phosphorus free fertilizers as a substitute of DAP for wheat cultivation, Chief Agriculture Officer Deepinder Singh suggested the use of other phosphorus containing fertilizers for wheat cultivation.
 The Chief Agriculture Officer said that DAP contains 46 percent phosphorus and 18 percent nitrogen, which is very important for crop growth. A major modification of DAP can be NPK 12:32:16 fertilizer; It contains 32 percent phosphorus, 12 percent nitrogen and 16 percent potash. One and a half bags of NPK 12:32:16 can be used in place of one bag of DAP. This change provides almost equal amounts of phosphorus and nitrogen; As much as DAP does, it also provides 23 kg of potash. Apart from this, other types of NPK fertilizers like NPK 10:26:26 can also be used as a substitute.
 The Chief Agriculture Officer said that Single Super Phosphate (SSP) can also be used as a third alternative to DAP. It contains 18 kg of sulfur with 16 percent phosphorus content, which is beneficial for crops like wheat. Three sacks of SSP supply sulfur along with phosphorus supply. Triple Super Phosphate (TSP) is also a new option In which 46 percent phosphorus content is found similar to DAP. It is a high phosphorus fertilizer and farmers can try it for the first time.
 Deepinder Singh said that if single super phosphate or triple super phosphate is used, it is also necessary to use 20 kg of urea per acre at the time of sowing to meet the nitrogen requirement of the crop. He said that this information can be useful as an alternative for farmers in case of non-availability of DAP. He appealed to all the farmers to meet the fertilizer requirement of their crops and maintain the fertility of their land according to these recommendations.
