Effect of traditional and nano phosphorous fertilization and soil moisture content on the growth and yield of two wheat cultivars, triticum aestivum l. in calcareous soil from Nineveh Governorate

Abstract EN

A pot experiment was conducted under greenhouse conditions to study the effect of phosphorus fertilization under to soil moisture content on some growth indicators, yield and seed content of nitrogen and phosphorous for two wheat cultivars, adnaniah and sham-6, in calcareous soil suffering from a lack of available phosphorus.

the results indicated that phosphorous fertilization led to an improvement in plant growth, as it caused an increase in the relative water content of leaves, chlorophyll percentage, nitrogen and phosphorous seed content, grain yield and protein percentage.

phosphorous fertilization played an important role in increasing the ability of the two wheat cultivars to withstand water stress conditions and reduce the negative impact resulting from the lack of water on plant growth, while the exposure of the two wheat cultivars to water stress there was a decrease in the values of previous growth indicators, grain yield and its content of n and p elements.

Sham 6 variety was more responsive than the adnaniya variety, as this variety outperformed in all the studied traits, in addition to that it obtained the best growth and higher yield under conditions of water shortage.
