| Abstract |
The aim of these investigation to study the effect of sulfur and gypsum alone or combination at saline sodic soil on some physical, chemical ,some nutrients and the yield of wheat Triticum vulgare Vill. (Sakha 93) crops.
A field experiment was conducted during winter season 2005 in a saline sodic soil at Koam Oshem Agricultural Research Station (El-Fayoum Governorate). Gypsum and elemental sulfur which was added alone or combined with them .The treatments that subjected in this study were nine treatments of amendments untreated i.e. control, gypsum at a rate 3 (ton /fed) (G1) and at rate 4.5 (ton/fed )(G2) and three treatment with elemental sulfur at control , 0.6 (ton/fed) (S1) and 0.9 ton/fed (S2) as well as their combination. Three replication were used in complete randomized block design .each block has area 14 m2 (4 m length and 3.5 m width), wheat crop (saka 69) were planted at growing season 2005-2006.
In regard to soil physical properties, i.e bulk density (g/cm3), pore size distribution %, total porosity %, total stable aggregates % , instability index. Chemical properties i.e pH ,EC ( dS/m) ,CEC(me/100 g soil) and ESP %. Available Macro and Micronutrients i.e N,P,K,Fe,Mn Zn and Cu (mg/kg in the surface studied soil) . and grains yield and grain + straw yield of wheat (ton/fed).
Data revealed that application of amendments alone are combination on bulk density (g/cm3) , fine capillary pors % (FCP) ,pH, EC dS/m instability index, ESP % decreased with increasing the dose of the studied amendments while total porosity % , pore size distribution % ie Quickly drainable pore ( > 28.8 µ) % (QDP) and slowly drainable pore % (28.8-8.60 µ) (SDP), Water holding pore % (8.62-0.19 µ) (WHP) , cation exchangeable capacity( ml/100g soil) (CEC) , availability N,P,K (mg/kg in the surface studied soil) availability of Fe,Mn ,Zn and Cu (mg/kg in the surface studied soil) with application of the studied amendments.
Grain yield was recorded 3.5 ton/fed while it was 1.05 ton/fed in untreated soil . The best increasing in grain +straw and it was 9.15 ton /fed , while it was 3.52 ton/fed in untreated soil
