Abstract

The current experiment was carried out in a clay soil Sids Agricultural Research Station, Beni-Suief Governorate, Egypt, during two successive seasons of ( 2017/2018 and 2018/2019). This investigation aimed to study the influence of planting methods and seeding rates on productivity of Egyptian clover forage and some water relations. The studied treatments were : four planting methods ( flat, ridges, raised beds and ridges without tillage) as well as three seeding rates,  15, 20 and 25 kg seeds/fed,. The results could be summarized as follows:- The treatment of flat or ridges method with 20 kg/fed seeding rate gave the highest values of plant height, leaves/stem ratio, fresh and dry forage yield as well as water use efficiency and water productivity.- The highest values of plant height, leaves/stem ratio as well as fresh and dry forage yields were obtained under flat or ridges planting method, while the highest values of these parameters were obtained under 20 kg/fed seeding rates.- Applied and seasonal consumptive use water were reduced under raised bed method followed by ridges( without tillage), while increasing seeding rates up to 25 kg/fed was significantly increased.- The raised bed method exhibited the highest values of water use efficiency and water productivity as fresh or dry basis. Also, the highest values of these water incidences were obtained under 20 kg/fed seeding rate.- The treatment of raised bed method with 15 or 20 kg/fed seeding rate recorded the lowest applied and seasonal consumptive water, consequently highest amount of saving water.
