The effect of adding solid and chelated liquid iron on the growth and yield of broad bean

Abstract

A field experiment was carried out within the randomized complete block design in the agricultural season 2020–2021. The experiment included two factors, the first factor was solid chelated iron (S0, S1, and S2 at concentrations 0, 100, and 200 ppm, respectively), which was added to the soil. The second factor was liquid chelated iron (L0, L1, and L2 at concentrations 0, 2, and 4 ml L–1 respectively), which was spraying on the plants. The results showed that the stem diameter, number of pods, and total yield were significantly affected by adding the 100 ppm iron solid chelated treatment (18.36 mm, 25.74 pod plant–1, 5.01 Mg ha–1 respectively). While 200 ppm treatment had the highest plant height (30.10 cm, yield (771.35 g plant–1), seeds (6.18 per pod). The treatment of 4 ml L–1 liquid chelated iron treatment had the highest plant height (128.55 cm), biggest stem diameter (18.63 mm), highest pods per plant (25.45), yield (755.98 g plant–1), total yield (4.80 Mg ha–1), pod length (24.87 cm), pod weight (28.14 g) and the number of seeds per pod (7.88). The use of the interaction between solid and liquid chelated iron improves the vegetative growth and yield of broad beans.
