Response of black cumin to vermicompost and nitrogen fertilizer

Abstract

An experiment was conducted to evaluate the response of black cumin (Nigella sativa L.) to vermicompost and nitrogen (N) fertilizer rates. Four rates of vermicompost and four rates of N were laid out in a randomized complete block design with three replications. The results showed that the interaction effects of nitrogen fertilizer and vermicompost rates significantly influenced black cumin growth, yield, and yield component parameters. The maximum seed yield (1,090 kg ha–1) was obtained from the combined application of 5 Mg ha–1 vermicompost and 60 kg ha–1 urea‐N. Therefore, it can be concluded that the combination of these treatments gives a better yield and yield components of black cumin in the study area.

Performance reaction and biochemical properties of black cumin under the influence of different regimes of nitrogen, menthol and drought stress

“…Increased grain yield with the consumption of 80 kg N/ha has been reported in black seed (Tulukcu, 2016). Increasing grain yield using low nitrogen levels in the study on soybean (Epie et al, 2022), black seed (Wako et al, 2022), barley (Armand et al, 2016), and pumpkin (Aghaee and Ehsanzadeh, 2011) has been reported. The increase in black seed yield with nitrogen consumption can be due to the effective role of nitrogen in the structure of chlorophyll, photosynthetic rate, and plant growth (Anas et al, 2020).…”
