| Abstract | ||
| An experiment was carried out in Diyala during growing season 2008 , to investigate the effect of three irrigation dates (7,14 and 21 Day) after flowering and tow levels of nitrogen (100 and 200 kg N.h-¹) in yield and yield components of cotton (var . lashata).The experimental design was randomized complete block design with three replications . was applied to show results as follow :The irrigation date at 21 day gave higher percentage of number of open bolls / Plant (85.97%),total number of bolls ( 45.42% ), seed index (10.53%) , weight of bolls (40.25%) lint yield (86.32%) , lint percentage (12.07%) ,and seed cotton yield (86.20%) ,as compared with irrigation date at 7 days . High level of nitrogen 200 kg . N.h-¹ open bolls /plant (23.33%), total number of bolls (16.87%) , seed index , (20.89%) gave higher percentage of number of and weight of bolls (40.87%) , as compared of application (100 kg .N.h-¹) and gave higher of lint yield ( 1169.85 kg .h-¹) as compared with (100 kg.N.h-¹). Asingificat interaction was observed between irrigation date at 21days and Nitrogen applied at (200 kg .N .h-¹) in all studied characters . | ||
