Subject(s): Online resources: In: Egyptian Journal of Agricultural Research 2004.v.82(4)Summary: Two field Experiments were conducted at Etai EI-Baroud Experimental Research Station, Behira Governorate during the two growing seasons of 2001/2002 and 2002/2003 to study the effect of relay intercropping cottar. with sugar beet using three dates for growing cotton; 151, 15t1i of March and April 151 and three levels of NPK fertilizer; recommended (60-30-48), recommended - 25 %, (45-22.5-36) and recommended + 25 % (75-37.5-60), on yield and yield components of sugar beet and cotton. The results indicated that: Sugar beet: Weight of root! plant, root diameter and sucrose percentage were not significantly affected by cotton relay intercropped in both seasons. Whereas, root length, % total soluble sugar (T.S.S), % purity and root yield/ fed were significantly affected by cotton relay intecropped with sugar beet. Total yield/ fed was significantly reduced by 15.54, 9.30 and 5.88 % in the first season and 15.27, 9.27 and 5.88 % in the second season when cotton was grown on March 1 51 , 15 tIi and April 1 51, respectively. Cotton: 1- Sowing cotton on March 151 sharply reduced all cotton growth characters and components and seed cotton yield/ plant and per feddan. Whereas, sowing cotton on March 15t1i was significantly higher in number of fruiting branches/plant, number of open bolls/plant, boll weight, seed index, seed cotton yield/plant and seed cotton yields/fed, compared with the other two dates. 2- Cotton fertilized by the recommended dose of NPK - 25 % (45, 22.5, 36) kgl fed gave significant increments in numbers of fruiting branches/plant, number of open bolls/plant, boll weight, cotton seed and seed cotton yields/ plant and per feddan.
