The aim of this study was investigation of PHARMAX nano fertilizer and its frequency of foliar application effects on morphological characteristics, straw yield, fruit yield, percentage and yield of essential oil of ( L.). A factorial experiment was conducted based on a randomized complete block design with 8 treatments and 3 replications. Factors were included frequency of foliar application (tillering stage and two weeks after the first foliar application) and concentration of nano fertilizer (0, 1, 3 and 5 ml/L). Finally, the results were statistically analyzed using MSTAT-C software and the mean data were compared with Duncan test at the statistical level of 5 %. The results showed that a significant effect of number of foliar sprays on plant height, number of umbrellas/plant, number of umbrellas/square meter, number of grain/umbrella, grain yield, straw yield, single plant grain weight, single plant biomass yield, percentage and essential oil yield. In addition, different concentrations of nano fertilizer had a significant effect on most traits except the number of grain/umbrella, 1000-Grain weight and essential oil percentage. The interaction of two factors on all traits except number of umbrellas/plant, number of grain/umbrella and percentage and yield of essential oil was significant. With increasing the concentration of nano fertilizer from 0 to 5 ml/L, the number of umbrellas/square meter, grain yields, straw and essential oil yield, increased 62.5, 74.1, 74.3, 186.8 % respectively. In addition, increasing the frequency of foliar application increased the mentioned traits. According to the results, it seems that the treatment of twice-foliar application and concentration of 5 ml/L nano-fertilizer was the best treatment due to increased yield and other traits.
本研究的目的是探究PHARMAX纳米肥料及其叶面喷施频率对（植物名称未给出）形态特征、秸秆产量、果实产量、精油百分比和产量的影响。采用随机完全区组设计进行析因试验，有8个处理，3次重复。因素包括叶面喷施频率（分蘖期和第一次叶面喷施后两周）和纳米肥料浓度（0、1、3和5毫升/升）。最后，使用MSTAT-C软件对结果进行统计分析，并在5%的统计水平下用邓肯检验比较平均数据。结果表明，叶面喷施次数对株高、每株伞形花序数、每平方米伞形花序数、每伞形花序粒数、籽粒产量、秸秆产量、单株粒重、单株生物量产量、精油百分比和精油产量有显著影响。此外，不同浓度的纳米肥料对除每伞形花序粒数、千粒重和精油百分比外的大多数性状有显著影响。两个因素对除每株伞形花序数、每伞形花序粒数以及精油百分比和产量外的所有性状的交互作用均显著。随着纳米肥料浓度从0增加到5毫升/升，每平方米伞形花序数、籽粒产量、秸秆和精油产量分别增加了62.5%、74.1%、74.3%、186.8%。此外，增加叶面喷施频率也提高了上述性状。根据结果，由于产量和其他性状的提高，两次叶面喷施和5毫升/升纳米肥料浓度的处理似乎是最佳处理。
