| Abstract | ||||
| Theeffects of (Pottasin-P) t as a potassium fertilizer under two levels of N fertilizer were studied. on some chemical constituents of the plant and the productivity of Giza 77, cultivar during two successive seasons; 1997 and 1998, at Sakha Agricultural Research Station. Spraying cotton plants by (Pottasin-P) TM tended to increase chlorophyll (a) and (b) as well as reducing sugars, total soluble sugars, nitrogen %, phosphorous %, total amino nitrogen % in leaves and protein% in seeds, but had no significant effect on oil % in seeds. N. fertilizer led to a significant increase in total soluble sugars, 11%, P%, total amino nitrogen in leaves and oil % in seeds. Spraying (Pottasin)TM on cotton plant caused an increase in plant height at harvest and number of open bolls per plant, and reduced boll weight and seed index (in one season), significantly increased seed cotton yield per plant (gm), seed cotton yield (in Kentars/feddan), and a slight increase in earliness percentage of yield. Lint micronaire reading and Pressley index were not significantly affected by any treatment. | ||||
