Abstract
Only few publications focus on the effect of humic substances plus foliar spraying with molybdenum on plants. Therefore, the objective of this study was to determine the influence of some humic substances (i.e., potassium fulvate and humate as a single treatment or in a combination) and the foliar application of molybdenum element (i.e., 0.0 and 50 mg L-1 as ammonium molybdate) on kidney bean (Phasuolas vlugaris L.; variety Nebraska) plants. The field trial was carried out in a private farm at Tanah Village, El-Mansoura District, El-Dakahlia Governorate, Egypt during two consecutive growing seasons (2017 and 2018). The experimental design was a split-plot with three replicates. The findings showed that the combined treatment of potassium fulvate with potassium humate under foliar application of Mo at rate of 50 mgL-1 was the superior treatment for vegetative growth criteria i.e. fresh and dry weights of shoot and plant height, chemical constituents in leaves i.e. chl.a, chl.b, chl (a+b), N, P, K , Mo and NPK nutrients uptake at a period of 45 days from sowing as well as yield i.e. pods and seeds weights and nutritional elements concentration in seeds i.e. nitrogen, phosphorus, potassium, molybdenum and NPK nutrients uptake at harvest stage of kidney bean plants. While the lowest values of all aforementioned traits were recorded with untreated plants (without both humic materials and Mo). Also, available N, P and K in soil after harvesting kidney bean plants pronouncedly differed due to all studied treatments.
