ABSTRACT
Zinc is the most common micronutrient fertilizer applied to rice plants in Egypt. To minimize yield reduction of rice grown by direct seeded methods due to Zn deficiency more knowledge about the proper method of zinc fertilizer application are required . Four yield trails(two for broadcast and two for drill methods) were conducted at Rice Research and Training Center ,Sakha,Kafr El-Sheikh,Egypt,during 2004 and 2005 rice growing seasons to study the effect of methods of zinc application on productivity of rice cultivars ;Giza 177,Sakha102 and Sakha104. The methods of zinc application in broadcast method were control ,seed soaking in 2% ZnSO4 solution , soil application at 24 kg ZnSO4 /ha and foliar spray as 2% ZnSO4 solution after 45 days from sowing ,while in drill method Zn applications were control, soil treatment at seeding with 24 kg ZnSO4/ha , 2% ZnSO4 solution mixed with herbicide, foliar application before flooding at2% ZnSO4 and soil application before flooding at 24 kg ZnSO4/ha . The results showed that straw and grain yields and its components of Sakha 104 rice cultivar surpassed the two other cultivars in both planting methods. All Zn applications increased grain yield by 8.14% in broadcasting and by 9.23% in drilling compared with unfertilized treatment (control). In broadcast seeded, there were no significant differences in grain yield and its attributes between foliar spray at2% ZnSO4 and soil application ,while seed soaking in 2% ZnSO4 solution performed the least values of all traits. In drill seeded rice all methods of Zn applications produced significantly the same yields of straw and grain.
