Abstract
The objective of this study is to assess the ameliorative impact ofpotassium humate (KH; 0, 100, and 200 kg per feddan) as soil amendments onthe growth traits, green and dry yields characteristics, leaf photosyntheticpigments, chlorophyll fluorescence, and leaf content of nutrients of commonbean (Phaseolus vulgaris L., cv. “Bronco”) plants grown under saline soilconditions. To perform the study aim, two field trials were conducted at theExperimental Farm of Faculty of Agriculture, Fayoum University during the2016 and 2017 summer seasons. The obtained results showed that, Na+ contentwas significantly declined, while the all other tested parameters such asgrowth characteristics (i.e., shoot length, number of leaves plant‒1, area ofleaves plant‒1, and shoot fresh and dry weights plant‒1), yield characteristics ofgreen pods and dry seeds (i.e., average pod weight, number of pods per plant,pods weight per plant, dry seed weight per plant and 100-seed weight), leafphotosynthetic pigments (i.e., total chlorophylls, total carotenoids) contentsand leaf chlorophyll fluorescence (i.e., Fv/Fm and PI), leaf contents of N, P,K+, and Ca2+, and the ratios of K+/Na+, Ca2+/Na+ and K++Ca2+/Na+ weresignificantly increased by the all KH treatments compared to the control(without KH). The two KH treatments conferred, approximately, the sameresults. Therefore, results of this study recommend using KH at 100 kg perfeddan to optimize the common bean performance in saline soils.
