The Effect of Nano-Fertilization and Tube Size on the Vegetative Growth and Yield Characteristics of Two Strawberry Cultivars

Abstract

The experiment was conducted in the unheated plastic house of the Department of Horticulture and Landscaping / College of Agriculture / University of Tikrit in the agricultural season 2021-2022. To study the effect of nano-fertilization at a concentration of 0, 1.5, 3 g, and planting with different sizes of plastic tubes with a diameter of 4, 6, and 8 inches on the vegetative growth and yield characteristics of two strawberry varieties, Fragaria ananassa Duch, Rubygem and Albion. The results showed that there were significant differences between the studied factors, as the tube was superior. 8 inch in the characteristic of the average number of leaves, as it reached 18.00 leaf plant-1, total chlorophyll reached 47.35 SPAD, the yield per plant reached 567.31 gm plant-1, and the yield of the plastic house reached 2297.6 kilograms of plastic house-1. While the two tubes exceeded 6 inch and 8 inch in A number of traits studied, including plant length, which reached 14.56 cm and 14.75 cm, respectively, and the area of one leaf, which reached 46.72 cm2 and 47.06 cm2, respectively, while the total area amounted to 285.63 cm2 and 275.16 cm2, respectively. The cultivar Albion was significantly superior to the cultivar Rubygem in the average plant length of 13.67 cm, in the average number of leaves amounting to 12.78 leaf plant-1, in the proportion of dry matter in the leaves amounted to 49.88%, in the yield of one plant amounted to 414.08 gm plant-1, and the yield of the greenhouse It reached 1677.03 kilograms of plastic house-1, while the foliar spraying with nano-fertilizer was significantly superior to spraying with a concentration of 3 g L-1 in the total chlorophyll content of the leaves and reached 45.61 SPAD, the yield of one plant was 546.62 gm plant-1, and the yield of the greenhouse reached 2213.82 kilograms of house. Plastic-1, while the concentration exceeded 1.5 gm L-1 in the average number of leaves, which reached 13.83 plant leaves-1.

The Impact of Short Storytelling on the Development of Yemeni EFL Learners' Oral Production

“…It prevents them from participating interactively in the process of teaching and learning. The study conducted by Yassin et al (2014) that investigated oral communication problems among Yemeni high school EFL students in Malaysia revealed that the oral problems could be categorized into three factors. Firstly, teachers were focused on the grammatical aspects while neglecting the practical side of the language and they did not encourage their students to speak English in class.…”
