Studying the Effect of Biochar, Vermicompost, Potassium Silicate and Perfusion Separator on the Physical and Chemical Properties of Soil and (Vigna radiate L.)

Abstract

The field experiment was carried out during the fall season 2022 at the Agricultural Research and Experiment Station (Mahatta). A affiliate To the College of Agricultural Engineering Sciences / University of Baghdad /mural for a purpose A study of the effect of biochar, vermi compost, potassium silicate and its separator Perfusion on the physical and chemical properties of soil And the growth, yield and quality of the mash inthe soil. With a split split panel design Split-Split Plot Design The coefficients were distributed using RCBD with three replications And with three factors, the main factor Main plottwo levels (4 days and 6 days) and the tokens were given (W3 and W6) sequentially and the second factor, Sub plot, potassium silicate Two levels of focus(0 and 1%) and symbols were given (S1 and S2) sequentially and the third factor under the secondary - Sub plot Sub Compost It includes both (Biochar, fertilizerworm, comparison(0, 4, 4) (Mg e-1 and the symbols are given(B0, B1, and B2) in sequence The mung bean was cultivated in Soil with a silty mixture texture Measurements were taken after harvest And Results shown The level of biochar addition was significantly higher in Soil physical and chemical properties For each of the Weighted diameter, organic matter and exchange capacity cationic And nitrogen, phosphorus and potassium in the soil.
