Effect of Spraying With Organic Sulfur and Hydrogen Peroxide on The Growth and Yield of Red Local Onions Allium Cepa L.

Abstract

The study was conducted in the fields of the Department of Horticulture and Landscaping/College of Agriculture/University of Al-Qadisiyah/Al-Nouriah district - for the 2019-2020 agricultural season to study the effect of spraying with organic sulfur and hydrogen peroxide on the growth and yield of onions, Allium cepa L, where the study included two factors: the first factor was spraying organic sulfur at concentration (0, 2)., 4 ml. L-1) and symbol S1, S2, S3 and the second factor spraying with hydrogen peroxide at a concentration (0, 2, 4 ml. L-1) and symbolized by B1, B2, B3 and the interaction between them. A factorial experiment was conducted according to the randomized complete block design (RCBD) with three replications and the comparison between the treatments was done using the least significant difference test L.S.D at the probability level of 0.05. The results showed that spraying with organic sulfur or spraying with hydrogen peroxide in a single form led to a significant increase in all studied traits, as well as the interaction between the two factors, where the treatment S3B3 recorded the highest significant increase in plant height, leaf length, number of leaves, leaf neck diameter and yield weight per hectare of 82.00 cm plant. -1, 63.0 cm, 11.00 leaf. Plant-1, 55.67 mm. Onion-1, 22.67 mm. Onion-1, 4.146 tons. hectare-1, respectively.

Efficiency of Fig Tree (Aswad Diyala) for Peeling and Spraying with Gibberellin and Iron on the Content of the Branches of Nutrients

“…As for the effect of iron on chemical properties, iron enters the composition of plant cytochromes responsible for the transfer of electrons and the synthesis of ferodoxin and participates in the process of oxidation and reduction in the process of respiration and photosynthesis and enters the composition of chloroplasts that contain total iron in plants and participates in the formation of plant proteins and participates in the activation of many Of the enzymes such as Nitrogenase and others, it has an important role and a catalyst for activating the reactions of the formation of green pigments through a series of compounds that end with the formation of the chlorophyll molecule, so the percentage of nitrogen and magnesium increases by adding iron because they are included in the synthesis of chlorophyll, and iron has an important role in the formation of nucleic acids and enzyme accompaniments such as cytochrome and catalase of importance In the process of photosynthesis, their ability to absorb mineral elements such as potassium increases in the branches, and this is consistent with what they indicated [12,21,22,23].…”

Comparing physiological role of L-methionine (sulphur containing amino acid) and its encapsulated nano-form on growth and crop productivity of onion (Allium cepa L.)

“…) shows the impact of methionine(50,75 and 100 mg/L) and its nanoparticles (5, 10 and 15 mg/L) on vegetative growth parameters of onion plant (plant height; number of leaves/plant; fresh and dry weight of leaves/plant and neck diameter). It was noted that methionine at 75 and 100 mg/L and its nanoparticles at 5 and 10 mg/L induced signi cant increases in plant height and neck diameter relative to control.…”
