| Abstract: |
In 2017 and 2018 summer seasons, two field experiments were conducted at, EL-Qantara East, Ismailia Governorate, Egypt to study the addition effect of biochar and compost in increasing N-fertilizer efficiency for Sorghum bicolor grown on a sandy loam. Four N-fertilization rates of 0, 60, 120, 180 kg N ha-1 (i.e. N0, N60, N120 and N180, respectively) and three organic sources 2 biochars and compost (i.e. BA, BB and Co, respectively) each applied at 24 Mg ha-1. Highest yield was by BB+ N180. Highest chlorophyll, protein and protein yield contents (41.3 mg g-1 fw., 118 g kg-1 and 2053 kg ha-1, respectively were obtained due to CoN180. Available N, P, K, Fe, Mn and Zn increased due to added treatments and highest were by CoN180. Soil pH decreased due to organic amendments while EC slightly increased owing to biochar addition. Maximum N, P, K, Fe, Mn and Zn content and uptake by plants were by CoN180. Highest Nitrogen Use Efficiency was by CoN120. The CoN180 had superior effect on improving soil properties and increasing sorghum traits.
