Effect of seeding, Belcocel and nitrogen fertilizer rates on yield and yield components of wheat under North Sinai conditions

Two field experiments were conducted at the experimental farm Agriculture Research Station, Desert Research Center, at El-Qantara, North Sinai Governorate, Egypt, during 2015/2016 and 2016/2017 seasons, to investigate the effect of three seeding rates (400, 500 and 600 seeds/m2), three belcocel rates (sprayed plants by tap water, belcocel at a rate of 750 cm3/fed once added and 375 cm3 twice added) and four nitrogen fertilizer rates (0, 70, 90 and 110 kg N/fed) on yield and yield components of wheat . A split- split plot design with three replications was used. Sowing wheat plants at seeding rate of 600 seeds/m2 gave the highest number of spikes/m2, spike length, number of grains/spike, grain yield/feddan and straw yield/feddan as compared with other seeding rates in both seasons, as well as harvest index in first season. Spraying wheat plant with belcocel at the rate of 375 cm3/feddan twice at 21 and 40 days from sowing date gave the highest values of number of spikes/m2, spike length, number of grains/spike, 1000 grains weight, grain yield/feddan, straw yield/feddan and harvest index in both seasons .Increasing nitrogen fertilizer up to 90 kg N/feddan significantly increased number of spike/m2, spike length, number of grains/spike,1000 grain weight, grain yield/feddan, strew yield/feddan, harvest index, in both seasons. Sowing wheat plants with seeding rate of 600 seeds/m2, sprayed by belcocel twice at the rate of 375 cm3/feddan and fertilized by nitrogen at the rate of 90 kg N/feddan gave the highest number of spikes/m2, spike length, number of grains/spike, grain yield/feddan, straw yield/feddan, harvest index as compared with all other treatments in both seasons.
