A pot house experiment was conducted at the Rajasthan College of Agriculture, Udaipur, Rajasthan (India), to find out relationship among edaphic factors for the development of root rot in ajwain (Trachyspermum ammi L.). Results revealed that maximum (30.0%) and minimum (12.0%) plant mortality at 45 days after sowing were observed in infected pot soil of Lalawas village (Chittorgarh district) and Kanad village (Pratapgarh district), respectively. Although at 75 days after sowing, maximum (49.5%) and minimum (18.2%) plant mortality was recorded in the soils of Lalawas village and Kanad village, respectively. However, overall maximum disease incidence (39.7%) was recorded in pots having soil of Lalawas village while it was minimum (15.1%) in the soil of Kanad village. This study suggests that delayed sowing predisposes the ajwain plants for Rhizoctonia root rot disease, so farmers should be advised for early sowing of ajwain crop.

盆栽条件下Ajwain根腐病发育的影响因素之间的关系研究

在印度拉贾斯坦邦乌代浦的拉贾斯坦邦农业学院进行了一个锅房实验,以找出促成阿贾因根腐烂(Trachyspermum ammiL.)。结果表明,在播种后第45天,分别在Lalawas村(Chittorgarh区)和Kanad村(Pratapgarh区)的感染盆栽土壤中观察到最大(30.0%)和最小(12.0%)植物死亡率。尽管在播种后第75天,分别在Lalawas村和Kanad村的土壤中记录到最高(49.5%)和最低(18.2%)的植物死亡率。但是,在有Lalawas村土壤的盆中记录到最大的总体疾病发生率(39.7%),而在Kanad村土壤中则是最小(15.1%)。这项研究表明,延迟播种易患的ajwain植物丝核菌根腐病,所以农民应该被告知为ajwain作物早播。
