Evaluation of some faba bean genotypes under three planting dates in middle Egypt

Abstract EN

The recent work was conducted in the Agricultural Research Stations of Mallawy, El-Minia Governorate and Sids, Beni-Suif Governorate, Egypt, during two successive winter seasons of 2016/2017 and 2017/2018 to study the effect of sowing date on productivity of eight faba bean genotypes, (Sakha-1, Sakha-3, Giza-843, Giza-716, Pop.

-10, SB-1, BF-10 and Sids-19).

Three sowing dates (October 15th, November 1st and November 15th) were used.

The results of the combined analysis of the two growing seasons 2016/2017 and 2017/2018 showed that, number of days to both flowering and maturity and number of branches were significantly affected by sowing date.

The productivity traits were significantly affected by sowing date, specially, seed yield per faddan.

The results revealed significant differences among the eight faba bean genotypes in their performance in both of number of days to flowering and maturity.

The earliest faba bean genotypes were Giza-843, Sakha-3 and Giza-716 in both Sids and Mallawy.

It was found that, late sowing showed a shorter period until to maturity.

Genotypes produced higher seed yield/plant at the 2nd sowing date (November 1st).

Genotypes produced heaviest 100-seeds in the 1st sowing date, because, plants stayed longer to reach maturity, relative to those planted in both of Novamber1st or November 15th, since seeds given much time to grow.

Sakha-3 in both Mallawy and Sids, attained the highest seed yield (tonfad.

).

The second sowing date (November 1st) was most proper and any of Sakha-1 and Sakha-3 Sids-19 might be adopted to Middle Egypt.
