A pot experiment was conducted during the summer season, 2015 to study the effect of graded saturation of phosphorus fixing capacity of soil on yield of maize. Application of P equivalent to 100% P fixing capacity of the soil in addition to recommended dose of fertilizer (RDF) significantly increased the dry matter yield (48.33, 78.33, 65.00 g pot−1) and yield attributes i.e. plant height (122.66, 131.44, 133.89 cm) and fresh yield (185.33, 319.67, 226.67 g pot−1) of maize over the control in all the three different soils (loamy sand, clay loam and clayey). The significant highest nitrogen, phosphorus, potassium and sulphur content and uptake by plants were obtained through saturating the 100% phosphorus fixing capacity of the soil in addition to RDF in all the three different soils. Likewise, highest productivity of maize was obtained from clay loam textured soil.
Maize positively response to the higher saturation of phosphorus irrespective of soil types.
Saturation of the 100 percent phosphorus fixing capacity of soils in addition to recommended dose of fertilizer promotes growth, productivity and nutrient uptake in maize.
Clay loam soil is superior in terms of productivity over the clayey and loamy sand soils of Gujarat.
