Abstract:
The research was conducted in the Kiswah region, Rif Dimashq Governorate, during the 2023 season, to study the effect of liquid Composeek Treatment (compost tea enhanced with Biochar and Wood Vinegar) on the growth and yield of pea plants. The experiment involved five concentrations (1, 2, 3, 4, 5 ml/l) of the commercial liquid composeek compound, in addition to the control treatment, were foliar sprayed. The experiment was designed using a completely randomized block design, and data were analyzed using GenStat software version 12. The results indicated improvement in the study parameters when using the liquid composeek, where plant height (53.12, 59.40, 65.35, 70.19, 80.14, 89.20 cm) for the experiment treatments respectively ranked higher. The leaf nitrogen content percentage also increased (10.29%, 14.29%, 18.29%, 32%, 57.14%) for concentrations (1, 2, 3, 4, 5 mL/L, respectively) compared to the control (1.75%). The concentration of 5 mL/L showed significant superiority over all treatments, reaching (67 pods/plant, 7.15 g/pod, 7.8 seeds/pod) for the parameters (number of pods, pod weight, number of seeds per pod, respectively) compared to the control (35 pods/plant, 4.5 g/pod, 5.9 seeds/pod, respectively).
