Abstract

The effect of direct, residual and cumulative effects of phosphorus fertilisation in Frenchbean—Cabbage—Okra cropping system was studied. The treatments included two levels of P (75 and 150 kg P/ha) and two sources of P (water and citrate soluble phosphorus). The results indicated that Frenchbean and Cabbage yields increased with the phosphorus level upto 75 kg P/ha. The subsequent crop Okra did not respond to phosphorus fertilisation. There was no difference in response due to sources of phosphorus applied. The results show a definite advantage of using less expensive citrate soluble phosphates to build up P status of the soils. Thus, fertilisation at the rate of 75 kg P/ha would build up the soil phosphorus to support three crops in sequence even in intensive vegetable farming systems.
