Abstract

In two seasons (1986/87 and 87/88), phosphorus ferti— lizer was applied as ordinary calcium superphosphate (OCSP) mixed with seeds of field beans (Vicia faba L. cv. Giza 2) at rates of 7.0, 10.5 and 14 kg P/fad. (16, 24 and 32 kg P205/fad.). It caused more growth and gave 57 and 14% mroe yield at the low and high rates than broadcast, and 37 and 19% more yield at the same respective rates than banding. Mixing OCSP with seeds has the same advantage as its banding in keeping the contact of fertilizer with soil to minimum P fixation. It also has the further advantage of securing sample P in the vicinity of seeds, and seedling roots at the earliest possible stage in crop life, both of which are crucial for growth and yield. Uptake of N, P and K as well as seed yield were all increased by this method. Under Egyptian conditions of (a)—soils being mostly clayey or calcareous or both and (b)-OCSP being powdered, appreciable fixation of P is invevitable; hence, this method is imperative especially if conditions dictate low rates.
