ABSTRACT

 

A field trial for two consecutive years (1999 and 2000) at Research Farm, College of Agriculture, Indore (India) was conducted in factorial randomized block design with sixteen treatments replicated three times in a soybean-wheat cropping sequence. The microbial population in soil was estimated by dilution plate count method. Application of biofertilizers significantly showed higher bacterial population during both the years of study. The fungal population increased in treated plot over control. Among the organics, biofertilizer increased fungal population at 25 day stage of the crop, while there was slight decrease in fungal population. Integrated use of chemical fertilizer with organics could ameliorate the soil and improve the productivity of a soybean-wheat cropping sequence resulting in eco-friendly farming system.
