| Abstract | ||||
| During 2018-2019 and 2019-2020 seasons, two-field experiments were conducted at El-Kasasin Horticultural Research Station, Ismailia Governorate, Egypt, to test the impact of potassium humate(KH) and biochar with substitution part of recommended mineral fertilization on growth parameters, physical, chemical characteristics of pods and green yield of snap bean as well as some physical and chemical soil properties after harvesting. The experiment was laid out in randomized complete block design (RCBD) with nine treatments included; solo application from 2 ton biochar+4 kg KH and 4 ton biochar+6 kg KH and each one was mixed with 25, 50 and 75% NPK from recommended dose comparing with 100% NPK. Overall, the results of this study indicated that soil addition of 75% NPK+ 4 ton biochar+6 kg KH recorded the best mean values of all tested parameters and improved growth, which reflected on yield and its components followed by 100% NPK. | ||||
