EFFECT OF PLANTING METHODS ON YIELD AND WATER REQUIRMENTS FOR SOME RICE VARIETIES (ORYZA SATIVA L.)

Field experiments were conducted at Sakha Agricultural Research Station Farm. Kafr El-Sheikh Governorate, Egypt during two successive growing seasons 2017 and 2018, to evaluate the performance of three Egyptian rice varieties under different planting methods as well as to determine the water requirements for each planting method. A split plot design with three replications was used, main plots devoted to the three planting methods as following: transplanting, terraces, and broadcasting, while rice varieties, (Sakha 101, Giza 178 and Sakha 105) were used and arranged randomly in sub plots. From the obtained data in both seasons, transplanting method gave the highest grain yield and significant values for most of the studied characters in comparison with the other two methods. Grain yield of transplanting method gave 8.201, 8.07 t\ha in the two seasons 2017 and 2018, respectively. Moreover, Sakha 101 variety gave the highest grain yield and surpassed the other two rice varieties. Water saving was high for Giza 178 and Sakha 105 when used terraces method in the two Seasons (42.6 and 40.05 % for 2017 and 2018, respectively. Thus, direct seeding methods using either broadcasting or terraces had comparative advantage over transplanted rice in terms of water requirements. Based on this investigation, direct seeded rice could be promoted since it showed potential for promotion.
