The effect of different planting dates on harvest, yield and quality of garlic cultivation in Diyarbakir

This research was carried out in the application and research area of the Department of Horticulture of Dicle Unıversity in 2017 Autumn vegatation period and 2018 spring vegatation period. In this study,it was aimed to determine the effect of different planting dates on harvest, yield, and quality of (in) garlic cultivation in Diyarbakir conditions in this research Taskopru garlic varieties, Tunceli garlic varieties and Cermik garlic, the local genotype of Diyarbakir was used. In this experiment fall and spring planting was made in two different periods. Planting was made in 4 different periods during the fall period (This dates: November 10, November 19, December 2 and December 10) in the spring period, 6 different dates were planted (This dates: February 21, March 3, March 10, March 21, April 1, April 15). In the experimental area of the plants; The number of leaves, plant head height, leaf length, head length, number of clove of garlic, clove of garlic width, plant head weight and yield were investigated. In our experiment study; Cermik garlic, general genotype of Diyarbakır in autumn planting grows earlier, during the planting in the spring period, the growth rate was observed to be slow. The highest yield was obtained from the planting during the fall period. Taskopru garlic has been the most efficient type with an average parcel yield of 1.68 kg as a result of the study it has been concluded that planting in the fall period in the cultivation of garlic in Diyarbakir conditions would be appropriate. Plantind was made on November 10, 219 days later; in 19 November planting poncels 210 days, in 2 December planting ponceis 198 days and in 10 December planting ponceis were havested 190 days later. The most convenience type of garlic will be Taskopru garlic in order to provide economical yield in garlic production during autumn.
