The Effect of the Combination of Organic Fertilizer and Spraying with Silicon and Calcium on the Growth and Production of Three Cultivars of Beet

Abstract

Field experiments were carried out for the autumn season 2022- 2021 in the field of College of Agricultural Engineering Sciences - University of Baghdad - Jadiriyah Complex –Station A- to study a combination of organic fertilizer (Vermicompost) and cow manure as well as a control treatment (soil only) intertwined with Spraying with silicon, calcium and distilled water (control) in the growth and production of three cultivars of beet (Cylindra, Dark Red, Red) within the design of Completely Randomized Block Design at three replications, The number of treatments was 9 for each replicate. The means were compared according to the least significant difference (L.S.D) at a probability level of 5 %, the results were as follows:-The interaction treatment of the Vermicompost with calcium spraying in the number of leaves, the concentration of chlorophyll, the percentage of nitrogen and phosphorous), was significantly superior to the combination of Vermicompost with spraying silicon significantly (in the percentage of potassium, the concentration of silicon, the root yield, the leaf yield, the percentage of dry matter, phenols and sugars), at a rate of (387.67,3%.28 mg kg−1, 35.88 ton h−1, 50 ton h−1, 8.78%, 014% and 889%) respectively. As for the percentage of calcium, it was characterized by the combination treatment of cow manure with calcium spray, and the combination of cow manure with silicon spray was superior in T.S.S. and the percentage of fiber at 3.17 and 11.66% respectively for the Red variety.As for the variety Red Dark it was significantly superior to the mixture of the medium vericompost with silicon spray in the number of leaves, the concentration of chlorophyll and the percentage of nitrogen, the concentration of silicon, Root yield and leaf yield Percentage of dry matter T.S.S, phenols and sugars at (10 leaf plant−1, 82.2 mg 100 fresh wet−1, 3.53%, 313.00 mg kg−1, 36.35 ton h−1, 40.92 ton h−1, 6.86%, 11.03%, 0.16% and 845%) respectively, while the percentage of phosphorous and potassium, it was characterized by the combination of cow manure with silicon spray, and the combination of vermicompost with calcium spray was superior to the percentage of calcium and the percentage of fiber by giving it 2.19% and 2.50% respectively. As for the variety Cylindra it was significantly superior to the combination of the Vericompost with silicon spray in the number of leaves, concentration of chlorophyll, percentage of nitrogen, phosphorous, silicon, root yield, leaf yield, Percentage of dry matter, T.S.S, Whereas, the treatment with cow manure overlapping with silicon was superior in the percentage of potassium, phenols and sugars, as it gave 4.11% 0.13 and 665% respectively, The treatment of the Vermicompost with calcium spray was characterized in the percentage of calcium as it gave 1.65%.
