EFFECT OF BIOTIC FACTORS AND CORM SIZE ON THE CORM YIELD OF FREESIA HYBRID L

Abstract

The experiment was conducted in the plastic house of the Department of Horticulture and Landscape Engineering at the College of Agriculture and Forestry/ University of Mosul in the agricultural season 2021-2022 to demonstrate the effect of corms size, aloe vera gel and biological fertilizers on the root characteristics of freesia plants. On 10/27/2021, corms (large and small) were planted in pots 22 cm in diameter in a sterilized soil with 5% formalin, consisting of sandy, mixed soil and peat moss at a ratio of 1:2:1. The experiment was carried out using a randomized complete block design (RCBD) with three factors with a study of their interactions. The biological factors were represented by the four concentrations of aloe vera gel (0-25-50-100)% ml .L , and the addition of biological fertilizers represented by the fungal bio fertilizer (T-22) Trichoderma hirzianum, which was loaded on millet, the soil was contaminated with an average of 5 g. pot as well as soil watering at a rate of 20 ml. A pot in addition to the bio-health fertilizer. The other pots were left without any treatment (comparison plants) for two types of large and small corms. The data was analyzed statistically using the SAS program, and the results were tested according to Dunkin's multinomial test under the level of probability 5%
