Study the Efficiency of Using Rock Phosphate with Organic and Biological Fertilization on Wheat Yield

Abstract

The main objective of the current study was to evaluate the effect of Phosphate rock (PR), application either alone or with some activators such as FYM and PSB wheat, growth characteristics, yield components, and some soil properties. Phosphorus (P) is often the limiting factor for plant growth because of its low mobility and availability in soils. Rock phosphates naturally occurring cheaper mean
of phosphorus (P) availability but having drawback of poor solubility. A field experiment was conducted. At the Ismailia Research Station, an agricultural research station in the Ismailia governorate of Egypt, during the two succeeding growing seasons of 2021–2022 and 2022–2023 to evaluate the effects of tow source phosphorus (P) (20 kg super phosphate/fed, 1 ton /fed rock phosphate and 2 ton
/fed rock phosphate),with natural stimulants application interaction with natural stimulants of farmyard manure (FYM) and phosphate solubilizing bacteria on Wheat growth and soil properties .The experiment design was a split-plot with three replicates. The results illustrated that rock phosphate application (2.0 tons/fed) recorded the significantly highest values of all studied parameters. Adding
FYM achieved the significantly highest results, followed by Bio-fertilizer application compared to control. The interaction between rock phosphate application (2.0 ton/fed) and FYM gave the best means on all studied parameters during the two seasons. The positive effect of rock phosphate application individually or with FYM and Bio-fertilizer might be related to enhancing soil properties, reducing
soil pH, and producing organic and growth hormones, causing an increase in nutrient uptake by plants and improving Wheat plants' growth and development.
