Effect of seeding rates and nitrogen fertilization levels on the productivity of Giza 157 Egyptian wheat cultivar.
1988
El Ghareib E.A. | El Monoufi M.M.
Two field experiments were conducted at the Gemmeiza Agric. Res. St. during 1985/1986 and 1986/1987 seasons to study the effect of seeding rates (30, 45, 60, 75 and 90 kg/fad) and nitrogen levels (0, 30, 60, 90 and 120 kg/fad) on yield and its components of Giza 157 wheat cultivar. The results obtained indicated that increasing seeding rates increased plant height and grain and straw yields/ fad while spike length, grains number and weight/spike, 1000-grain weight and harvest index were decreased. Many of the characters studied were increased with increasing nitrogen levels application except for 1000-grain weight and harvest index which were decreased, in both seasons. No significant interactions were observed between nitrogen levels and seeding rates in both seasons except for grains weight/spike, 1000-grain weight and grain yield/fad in the second season as well as straw yield/fad and harvest index in the two seasons.
