چکیده [English]

This research was carried out with the aim of studding the effect of chelate and nanochelate of potassium foliar application on some growth and physiological characteristics of basil (Ocimum basilicum L.) under deficit irrigation stress. The study was conducted as a factorial experiment in a randomized complete block design with three replications in the greenhouse of Agriculture Faculty of Bushehr University in 2016-2017. Plants were subjected to four deficit irrigation stress levels (100, 80, 60 and 40% of field capacity moisture). Four different rates of chelate and nanochelate of potassium (0, 1, 3 and 5 g/L) were applied through foliar spray. The results indicated that deficit irrigation stress significantly (p
