| Abstract | ||
| The objective of this research is to study the effect of phosphorus (30,45,60 and 75Kg P205/fed.) and potassium (48 and 72 Kg K20/ fed.) applications as a single or in combinations, on lupin yield and some growth characters as well as seed nutrient content of Giza 2 variety. The obtained results showed that P application at 60Kg P205/fed. alone or in combination with 48kg K20/fed. gave significant increases in plant height and number of branches and pods/plant, whereas its combination with 72Kg K20/fed. significantly increased 100- seed weight and straw and seed yeild /fed. as compared to control. Increasing P level up to 60Kg P205/fed. increased seed contents of protein, P and K. K application at 72Kg K20/fed. decreased seed protein and increased P and K percentages in seeds. All combination treatments. except for the combination of 45Kg P205 with 48 or 72 Kg K20/fed ., significantly increased seed contents of protein , P and K. It could be concluded that 60Kg P205/fed. can be recommended for lupin fertilization in sandy soils. | ||
