Impact of Microbial Cultures on Soil Biological Quality and Growth of Spinach Grown in Polluted Soils

摘要

In this present studied poly bag experiment was conducted following complete randomized block design with~(-1)2 treatments and three replications. Polluted Soil with supply of fresh water, Unpolluted soil with supply of fresh water, Unpolluted soil with supply of polluted water. The results of pot culture were reveals that the Influence of microbial cultures on biological quality and microbial population of polluted soil and spinach yield at 30 and 60 DAS was estimated. Significantly highest bacterial population was recorded in treatments T12 (124.21 X10~7CFU g~(-1) soil) at 30 DAS and treatment T_8 (88.68 X10~7CFU g~(-1) soil) at 60 DAS. The highest molds population was observed in treatment T_3 (17.91, 11.32 X10~3CFU g~(-1) soil) at 30 and 60 DASrespectively. The treatment T_6 showed significantly highest rhizobial population at 30 and 60 DAS (29.23, 20.71 X103CFU g~(-1) soil) respectively. The VAM population was highest in the treatment T7 (24.13 X10 g~(-1) soil) at 30 DAS and T12 (9.0) at 60 DAS. The highest leaf fresh weight was recorded in T_8 (41.63 g plant1) at 30 DAS and (70.03 g plant~(-1)) at 60 DAS and the lowest fresh weight was recorded in T_3, T_9 at 30, 60 DAS respectively. The highest leaf dry weight was recorded in T_8 (6.62 g plant~(-1)), (4.17 g plant~(-1)) at 30 and 60 DAS respectively and the lowest values were found in T_3 at 30 and 60 DAS.
