Effect of moringa leaf extract, Kinetin and humic acid on the growth and yield of Rocket plant

Abstract

This experiment was conducted in an orchard in Babylon province - Al-Kifl district, in autumn season of the year 2021-2022, on the Rocket plant (Eruca vesicaria subsp.sativa).To know the effect of the first factor, Moringa extract at concentrations of 10 g/L, 20 g/L, and Kinetin at concentrations of 20 mg/L, 40 mg/L, and the second factor, humic acid at concentrations of 2 kg/ha, 4 kg/ha, with the control treatment (without addition or spraying) for each factor and the interaction between factor on the growth yield of Rocket .It was conducted as a factorial experiment (5x3x3) according to the Complete Randomized Blocks Design (R.C.B.D) and with three replicates, where each replicate contains 15 treatments. The results showed that there are significant differences in the vegetative traits of Moringa extract, chitin and humic acid. The results indicate that the treatment of Moringa leaf extract with a concentration of 10 g / L was excelled in giving the highest plant height (57.95 cm), the highest number of leaves (19.09), and the highest percentage of dry matter for the first cutting (6.040 %).The results also indicate that the treatment of Kinetin with a concentration of 20 mg / L was excelled in giving the highest dry weight for the first cutting which reached (5.437 %) and the highest dry weight for the second cutting was (5.923 %). (2.252 tons) and the highest yield for the second cutting was 1.737 tons. The results also indicate the humic acid treatment at a concentration of 4 kg / ha excelled by giving the highest plant height (58.87 cm), the highest percentage of dry matter for the second for cutting (7.083 kg), and the highest yield for the second cutting 1.464 tons/ha (Likewise, the humic acid treatment excelled at a concentration of 2 kg / ha by giving the highest yield for the first cutting, which reached (1.926 tons), and the control treatment excelled in the number of leaves, recording the highest mean of 18.34.As the signals of the results in the interaction in trait of plant height .The treatment, M2H2, recorded the highest average of (70.25 cm). As for the number of leaves, it was recorded as M1H0, and the highest average was   25.80In trait of the percentage of dry matter for cutting first, the treatment M2H2 recorded the highest average of (6.88) kg.As for the percentage of dry matter for cutting the second, the treatment M3H2 recorded the highest average (7.525 kg). As for the yield of the first for cutting, the treatment M4H2 recorded the highest average (2.580 ton/ha). As for the yield of the second for cutting, the treatment M2H1 recorded the highest average (2.093 %(
