Title : Studies on Phosphorus fractions under P × Fe interaction in Maize

Abstract :

Limited information is available on the impact of phosphorus and iron interaction. Therefore, a study was undertaken on sandy loam (light textured) and clay loam (heavy textured) soil in a screen house taking maize as a test crop. In both light and heavy textured soils, Saloid-P content of soil was increased up to highest level (40 mg kg-1) of P application. Application of various levels of Fe either as soil or foliar spray did not influence significantly the Saloid-P content of both type of soils. In light textured soil, application of phosphorus significantly affected the Al-P in the soil up to the highest level. Application of Fe either as soil or foliar spray did not improve Al-P fraction significantly, rather, numerically it was decreased as compared to control. There was an increase in Al-P content of heavy textured soil with increasing level of P application. The results did not show any significant differences in Al-P as a resultant of Fe application either as soil or foliar spray. Under both light and heavy textured soils, there was numerically increase in Fe-P with the increase in P level over control, while Fe application resulted in decrease in its fraction with increase in Fe level. With the increasing rate of P application in light and heavy textured soils, Ca-P fraction was also increased. Non-significant effect of Fe application either as soil or foliar spray was observed for Ca-P content. It decreased with increasing level of Fe application over their respective controls under both light and heavy textured soils. Phosphorus and Iron are found to be negatively interacting at higher level of application of iron.
