The Effect of Water Shortage and Foliar Application of Salicylic Acid on Quantitative and Qualitative Performance of Cumin Herb

Abstract

The outcome of different levels of drought stress and salicylic acid on quantitative as well as qualitative performance of cumin herb and split-plot test with entirely randomized block design has been conducted for four-times, in the city of Khash in 2013-14. The treatments includes foremost factor of stress in three different levels of controls vis; umbelet stage, grain filling and the sub factor of salicylic acid in four-levels namely 1.5, 0.7, 0.1 and 0 mm. In this experiment, the characteristics measured and investigated are height of plant, number of seeds per umbel, number of umbels per plant, grain yield and weight, grain yield per plot and wet and dry forage yield as well. Results, evidently displayed the dryness and foliar application of salicylic acid’s influence on the most of the characteristics. On one hand, dryness caused a negative impact on these attributes and on the other hand, foliar application of salicylic acid has visibly improved these features.
