Effect of cultivation distances on growth and productivity of two varieties of garlic under the conditions of El jabal Al-Akhdar

Abstract

The research was carried out by the Department of Horticulture - Faculty of Agriculture - University of Omar Al-Mukhtar - White during the 2013-2014 and 2014-2015 planting seasons. To study the effect of four planting distances (5, 7.5, 10, 12.5 cm) on the behavior of two varieties of garlic (Egyptian "municipal", Chinese). The design of full randomized splitters was used once in three replicates. The mean of the treatments was measured according to the Duncan test at a significant level of 5%. The results showed that the gradual increase of the planting distance (5, 7.5, 10, 12.5 cm) resulted in a gradual and significant increase in the average length of the leaves, the average number of leaves, the paper area and the dry weight of the leaves in both cultivars. The best results for the leaf content of nitrogen and phosphorus at planting distance were 12.5 cm, while potassium was at a distance of 5 cm. The content of the leaves of chlorophyll (A, B) in both cultivars increased by increasing the distance of cultivation with the superiority of the Chinese class on the Egyptian. The results showed that increasing the planting distance to 12.5 cm increased the average weight of the bulb, the exportable yield and the exportable yield of the total crop, while the total yield decreased with the increase of the planting distance. The highest percentage of nitrogen was recorded at a distance of 12.5 cm for the Egyptian variety, while the Chinese category recorded the highest percentage of phosphorus and potassium. The results showed no significant differences in mean weight of the lobes between the four planting distances of the Egyptian and Chinese varieties during the first and second seasons. The best results were achieved for total dissolved solids at a distance of 12.5 cm in the Chinese and Egyptian varieties, respectively.
