Abstract
Field experiment was carried out in AL-Musaib Technical Institute during growing season of 2001 and 2002, to investigate the effect of three nitrogen (0,100,and 200 kg.h-1 )and three foliar date Zinc and Copper (after thinning, beginning first square and beginning of flowers) on yield and yield components of cotton (cv. lashata ). The experimental design was arandomized complete block design with three replications .The results showed that. Nitrogen applied at 200 kgN.h-1 during both seasons gave higher number of open bolls /plant ( 33.33 and 34.04 bolls ), total number of bolls (41.81 and 41.26 bolls ) seed cotton yield (2739 and 2970 kg.h-1) respectively as compared with control treatment with gave lower number of open bolls /plant (9.15 and 8.52) , total number of bolls/plant (18.78 and 17.48 ) seed cotton yield (797 and 447 kg.h-1),seed index and weight boll gave higher in the both seasons The foliar date during flowering of both season gave higher number of open bolls/plant (26.07 and 26.63 bolls ),number of total bolls /plant (41.81 and 41.26 bolls ) seed index, weight of bolls and seed cotton yield (1983 and 2089 kg.h-1) respectively as compared with foliar after thinning . The interaction between nitrogen applied at 200 kg.h-1 and foliar during flowering in all properties were studied in this research.
