TLDR
This review mainly covers the following topics: impact of drought on plant growth, physiological and biochemical characteristics, the role of K in plantgrowth, and physiology under drought stress.Abstract:
Drought stress affects plant growth and ultimately yield is reduced. Potassium (K) is an essential macronutrient that is required to increase the growth and yield under drought. K plays an importan...read more

Exogenous application of β-sitosterol mediated growth and yield improvement in water-stressed wheat (Triticum aestivum) involves up-regulated antioxidant system.
Amr Elkeilsh,Yasser M. Awad,Mona H. Soliman,Mona H. Soliman,Abdelghafar M. Abu-Elsaoud,Magdi T. Abdelhamid,I. M. El-Metwally +6 more
TL;DR: Application of BBS at 100 mg L−1 was beneficial and can be recommended for improving the growth and yield of the wheat crop under water stress and reduces the generation of hydrogen peroxide and hence the malondialdehyde content significantly in water-stressed and well-watered wheat plants.
