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

Abstract

This experiment was carried out during the 2021-2022 growth season to test the effect of the sowing date (1^st October and 21^st 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 21^st October sowing date was superior to the 1^st 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 21^st October, 5.0 g.L^-1 bio-health and 2.0 ml.L^-1 amino acid.
