Abstract :Effects of rice husk compost insert ignore into journalissuearticles values(RHC); on some soil quality parameters under greenhouse conditions were investigated. Experiment were conducted in a randomized plot design with different application doses of RHC insert ignore into journalissuearticles values(0, 3, 6 and 9%); into surface soil insert ignore into journalissuearticles values(0-20 cm); with three replications in a greenhouse of Agricultural Faculty in Ondokuz Mayıs University. RHC application generally improved the soil quality parameters according to the control treatment during the experiment carried out with growing tomato plant in the greenhouse in 2010. The soil organic matter insert ignore into journalissuearticles values(OM); contents significantly increased by the application of RHC in the following order; 9%>6%>3%>0%. While RHC applications in the greenhouses significantly reduced pH contents of soils according to the control, the RHC application increased the values of respiration rate insert ignore into journalissuearticles values(CO 2 );, EC, NO 3 -N and available phosphorus insert ignore into journalissuearticles values(P);. While the exchangeable Ca values of soils generally decreased, the exchangeable Mg and K values generally increased according to the control with RHC application. Bulk density insert ignore into journalissuearticles values(BD); values in the greenhouse were reduced with RHC application doses in the following order 0%>3%> 6%>9%. The values of field capacity insert ignore into journalissuearticles values(FC);, permanent wilting point insert ignore into journalissuearticles values(PWP); and available water capacity insert ignore into journalissuearticles values(AWC); generally increased according to the control with the application of RHC dosses in the following order 9%>6%>3%. The highest positive correlations among the physical, chemical and biological properties were found between OM and PWP insert ignore into journalissuearticles values(0.924**);, AWC and FC insert ignore into journalissuearticles values(0.907**);, OM and FC insert ignore into journalissuearticles values(0.897**);, CO 2 and PWP insert ignore into journalissuearticles values(0.862**);, PWP and FC insert ignore into journalissuearticles values(0.791**);; while the highest negative correlations were found between BD and FC insert ignore into journalissuearticles values(-0.854**);, BD and PWP insert ignore into journalissuearticles values(-0.871**);, BD and OM insert ignore into journalissuearticles values(-0.868**);, BD and CO 2 insert ignore into journalissuearticles values(-0.838**);, BD and P insert ignore into journalissuearticles values(-0.821**);, Ca and FC insert ignore into journalissuearticles values(-0.812**);. The highest tomato yield insert ignore into journalissuearticles values(7.77 ton/da); was obtained with the 9% of RHC application. RHC application to the soil in greenhouse generally improved soil quality and tomato yield.
