Effect of Sowing Date, Bio-health and Amino Acid on Vegetative Growth and Yield of Pea (Pisum sativum L.)

This experiment was carried out during the 2021-2022 growth season to test the effect of the sowing date (1st October and 21st October), three levels of bio-health (0.0, 5.0, and 10.0 g.L-1), and three levels of the amino acid (0.0, 2.0 and 4.0 ml.L-1)  on different growth and yield parameters of the pea plant. The experiment was implicated in a Randomized Complete Block Design (R.C.B.D) and replicated three times. The result showed that the 21st October sowing date was superior to the 1st October in branch number plant-1, pod number plant-1, and total yield (t.ha-1). Applications of bio-health significantly increased most traits. It was also noticed spraying amino acid at a concentration of 2.0 ml.L-1 had a significant effect on branch number plant-1, total chlorophyll%, pod number plant-1, pod weight (g), and total yield (t.ha-1). The combination of sowing date, bio-health, and amino acid significantly enhanced all studied traits, especially on 21st October, 5.0 g.L-1 bio-health and 2.0 ml.L-1 amino acid.
