| Abstract | ||
| This study was conducted during the autumn seasons of 2022/2023 and 2023/2024 at the Horticultural Research Station in El-Kassasin, Ismailia Governorate, Egypt, to test the effect of some agricultural practices such as soil tillage and the use of some organic alternatives to partially replace mineral fertilizers such as humic acid and fulvic acid as a soil additive with the aim of improving the growth parameters, green yield , nitrogen use efficiency and pods quality of snap bean plants. Soil tillage and fertilization with mineral NPK at 75% of recommended rate (60 kg N, 27.75 kg P2O5 and 37.5 kg K2O/fed.) in combinations with humic acid and fulvic acids at 6 kg /fed. of each as organic fertilization increased fresh and dry weight of roots, branches and leaves, s well as chlorophyll a, b in leaf tissues, N, P and K contents in shoots, yield / plant and total yield /feddan, in addition of N, P, K and total protein contents in pod, while fertilizing snap bean plants with mineral NPK at 50% RR combined with HA+FA at 6 kg /fed. each under tillage practice produced the highest values of nitrogen use efficiency of snap bean (Paulista cultivar) grown in sandy soil. | ||
