The Effects of Varying Nitrogen Doses Some Yield Components of Nigella Sativa L.

Eray Tulukcu


This study was carried out to determine the effects of different Nitrogen doses (0, 40, 80 and 120 kg/da) on yield and some yield components of black cumin (Nigella sativa L.) in Cumra/Konya ecological conditions in 2010 and 2011. Field trials were designed by Completely Randomized Block Design with four replications at the experimental fields of Cumra Vocational High School of Selcuk University. In the study, plant height (cm), the number of branch (branch/plant), the number of capsule (capsule/plant), the number of seeds in the capsule (seed/capsule), thousand-seed weight (g) and seed yield (kg/ha) were determined. According to statistical analysis, significant differences were determined among the nitrogen doses applications for the number of branch and thousand seed weight. The seed yield increased by increasing nitrogen doses then it decreased. According to the results, the highest seed yield (740 kg/ha) and thousand-seed weight (3.54 g) were obtained from 80 kg N/ha fertilizer application. The highest mean values for the number of capsule (8,58 capsule/plant) resulted in 80 kg N/ha application.
