Two field experiments were carried out at the Researches and Production Station of the National
Research Centre (NRC) at Al Nubaria district, El-Behaira Governorate, Egypt during 2008/09 and 2009/10
winter seasons. Five faba bean varieties (Cairo -4, Cairo -5, Cairo -25, Nubaria -1 and Giza -843) were seeded at
(20, 40 and 60 cm between rows) which were 42, 25, 16 plants/m in newly reclaimed sandy soils. Results

indicated that faba bean varieties varied significantly in all studied characters. Nubaria-1 and Cairo-25
varieties produced high seed and protein yields per feddan and significantly out yielded the other varieties.
Increasing plant density significantly increased seed and protein yields per feddan as well as plant height,
100-seed weight and biological yield per feddan. On the other hand, increasing plant density decreased
number of branches and number of pods per plant, pods and seed yields per plant, number of seeds per pod
and harvest index. Results also indicated that the interaction between varieties and plant density had
significant effect in all studied characters. Nubaria-1 variety produced the highest seed and protein yields per
feddan when it seeded at 20 cm between rows and significantly out yielded the other all varieties. However,
Cairo-25 and Nubaria-1 varieties produced high biological yield per feddan when they seeded at the highest
plant density.
