Effect of G Power Ca + Nanocomposite and Bio-Fertilization on the Chemical and Yield Parameters of Sunflower

Abstract

A field experiment was conducted on the west side of AL-Jadwal Al-Garbi  /Hindi/ Karbala, Iraq, during the spring agricultural season of 2023. The objective was to evaluate the effect of G power Ca + Nanocomposite spraying and Bio-Fertilization using Pseudomonas bacteria on sunflower yield and seed quality. Two factors were studied. First foliar spraying of G Power Ca+ Nanocomposite at three concentrations (2.5, 4 and 5 m.L-1). Second, Soil application of Pseudomonas bacteria at four levels (0, 10, 20 and 60 m .L-1) injected into Rhizosphere.

Measured parameters included Plant height,  number of seeds per disc, biological yield  and seed content of oil, protein, and nitrogen. The highest values were recorded at 5 mL-1 G Power Ca + Nanocomposite and 60 mL-1 Pseudomonas levels, with significant differences from control treatments. These findings highlight the potential of that combining Nanocomposite and bio-fertilizer treatment improves sunflower yield and nutritional quality under arid conditions.
