Recent data indicates that in 2021, the average phosphorus (P₂O₅) fertilizer consumption in West Bengal was approximately 54.36 kg per hectare. This figure reflects an increase from 48.34 kg per hectare in 2020. Over the past two decades, phosphorus fertilizer use in the state has varied peaking at 64.13 kg per hectare in 2006 and reaching a low of 27.19 kg per hectare in 2014. While this data pertains to overall agricultural land in West Bengal specific figures for phosphorus fertilizer application exclusively in rice fields are not readily available in the provided sources. However, considering that rice is a major crop in the region, it's reasonable to infer that a significant portion of the phosphorus fertilizer is applied to rice cultivation.
