| Abstract | ||||
| Two field trials were conducted during the consecutive seasons of 1997/1998 and 1998/1999 at the Agricultural Experimental Station , National Research Centre (NRC), Cairo, at Shalakan, Qualiubia Governorate, Egypt , on three wheat varieties namely Sids 1, Sakha 69 and Gemaiza 3, to investigate the nutrient status, growth and yield responses to micronutrients foliar application . That was to gain information about the effeciency in aquisition and utilization of nutrients .The results showed that , spraying micronutrients compound (Wuxal suspension micro- Zn contained Fe 1.35 % , Mn 2.7 % and Zn 4.0% ) resulted in improving plant nutritive status, leading to increasing the growth in terms of shoot dry weight , grain yield and total carbohydrate and protein content in grains of all varieties under investigation , in comparison with non- treated plants . In addition, the results revealed that the positive response of the foliar applied micronutrients varied in degree between the three wheat varieties . Sakha 69 variety gave the highest grain yield at the rate of micronutrients 3.0 ml/l , and Sids 1 variety produced the highest percentage of total carbohydrates in grains at the same rate. Meanwhile, highest protein percentage in grains was obtained by Gemaiza 3 variety at the rate 1.5 ml/l . Significant interaction effect between micronutrients application and varieties for all studied characters except the plant height was found . These results might reflect the different responses due to genetic factors of the three wheat varieties to micronutrient application . Furthermore, the present study suggests that micronutrients foliar application can be used to improve nutrient status and yield production of all varieties . | ||||
