Abstract
A field experiment was conducted in Al-Souera, 50 km south of Bagdad in the winter season 2019/2020 to study two levels of boron spray (control and 2 mg L-1), three levels of amino acids (control, 1.5 and 3 mg L-1), and four levels of Silicon as potassium silicate (control, 1, 2 and 3 mg L-1). A randomized complete block design with three replications was used. The spraying process was done in two periods (45 and 90 days after planting). Pea seeds were planted in hills 30 cm apart on ridges 80 cm apart. The results showed that boron spraying caused significant increases in plant length (112.27 cm), leaf area (101.2 cm2), branches number per plant (8.4), leaves number per plant (88.41), chlorophyll index (43.91 SPAD), and plant dry seed yield (57.7 g). Amino acids spray treatments gave a significant effect and the level of 3 mg L-1 was superior in plant length (110.02 cm), leaf area (100.9 cm2), branches number per plant (9.0), leaves number per plant (89.20), chlorophyll index (44.09 SPAD), and plant dry seed yield (57.9 g). The potassium silicate spraying caused a significant effect compared to control treatment and the level of 3 mg L-1 was superior in plant length (110.61 cm), leaf area (99.7 cm2), plant branches number (8,3), plant leaves number (80.02), and plant dry seed yield (50.7 g). The interactions between the factors caused a significant effect on many studied traits.
