Abstract

This work was carried out during the two successive growing seasons of 2019 and 2020 at the farm of Animal Industrial Feeding Factory at Shosha Village, Production Sector, Agricultural Research Centre, Ministry of Agriculture, and Laboratory of Floriculture, Faculty of Agriculture, Minia University, to study the effect of mineral fertilization and number of cuts on the vegetative growth of guar (Cyamopsis tetragonoloba, (L.) Taub.) plants. Data revealed that increasing mineral NPK level led to a significant increase in plant height, number of branches and herb fresh and dry weights as compared with control. While, without cut treatment (control) was superior to other cutting treatments (one, two and three cuts) on increasing all studied previous parameters except number of branches.It can be noticed that the highest level of NPK mineral fertilization (500 kg/fed comprised of 200 kg ammonium sulfate + 200 kg calcium supper phosphate + 100 kg potassium sulfate) in combination with applying three cuts led to the greatest branch number
