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.
对黑孜然(Nigella sativa L.)对蚯蚓堆肥和氮肥施用量的反应进行了评价。采用三次重复的随机完全块设计,确定了四种蚯蚓堆肥率和四种氮肥率。结果表明,氮肥和蚯蚓堆肥量的交互作用显著影响黑孜然的生长、产量和产量组成参数。最大种子产量(1090 kg ha–1)来自5 Mg ha–1蚯蚓堆肥和60 kg ha–2尿素的联合施用。因此,可以得出结论,这些处理的组合在研究区域内提供了更好的黑孜然产量和产量成分。
