Abstract

This laboratory and field experiment were to assess the use of rice straw (RS); biochar rice straw- compost (BRS); rice straw- ammonium (RSN) and compost (ST) at 0, 12.5 and 25 Mg ha-1 on the development of wheat plants and improve a sandy soil's productivity. In winter seasons of 2017/2018 – 2018/2019 at the Ismailia Agricultural Research Station. In laboratory experiment soil treatments incubation and studied OC%, SP, FC, PWP and AW. In field experiment i.e. yield, yield components, N, K and P, pH, ECe and bulk density at ripeness's stage, times application before sowing (Ap1) and with sowing (Ap2) on wheat and study design a split  block. Results the end of incubation period, losses of OC% about 21.2, 7, 20.6 and 32.1% due to 25 Mg ha-1 for RS, BRS, RSN and ST respectively, we found a positive effect of rice straw and compost on SP, FC, PWP and AW. In field experiment the highest relative  increase over control due to 25 Mg ha-1 BRS, RSN and ST at Ap1 for  plant height were  36.58, 68.95 and 74.73 %  where dry weight/plant were 35.00 48.44  and 69.06 %, grain yield were 45.13, 58.70 and 69.32%.  100 seed weight and N K P content significant affected by BRS, RSN and ST respectively. Soil available N,  K and P due to all organic treatments. Soil EC was improved by RSN and ST, addition of ST impact on pH and bulk density was slightly reduced, but BRS was due to a slight increase.
