Abstract
An observable discrepancy was noted in the abundance of soil cryptostigmatids across different treatments. The highest abundance of soil cryptostigmatids (4.28/400g) was recorded in plots that followed a recommended package of practices, which was comparable to the higher farmyard manure dose applied plots with reduced fertilizer doses and farmyard alone treatments. Notably, the lowest soil cryptostigmatid population was observed in the recommended fertilizer alone treatment (2.64 cryptostigmatids/400g of soil). The cryptostigmatids population gradually increased and peaked 105 days after sowing. At 45 days after sowing, the soil microbial biomass carbon content was significantly higher in plots treated with 20 t of FYM alone and lower in plots treated with recommended fertilizer alone. Furthermore, there was a significant positive correlation (0.277**) between cryptostigmatid abundance and microbial biomass carbon.
