Influence of different tillage, cropping sequence, mulching and fertility levels on microbial population

Abstract:
The field experiment was conducted at Agricultural Research Farm BHU Varanasi during Kharif, Rabi and summer season 2012-13 and 2013-14 to evaluate the microbial population under two tillage practices (reduced tillage and conventional tillage) four cropping sequence; (rice-wheat, rice-potato-green gram, maize-mustard-green gram and DSR-maize-green gram), two mulching treatments; (mulching during rabi and no mulch) and two fertility levels (75% RDF +25% N through FYM and 100% RDF) with three replications in Split Plot Design. The results revealed that reduced tillage significantly increased the population of Bacteria ×105 CFU g-1, Actinomycetes ×105 CFU g-1 and Fungi ×105 CFU g-1 in soil over the conventional tillage. Significant increase of Bacteria ×105 CFU g-1, Actinomycetes ×105 CFU g-1 and Fungi ×105 CFU g-1 in soil under maize-mustard-green gram cropping sequence were noticed over rest of the cropping sequences. Mulching significantly increased the population of Bacteria ×105 CFU g-1, Actinomycetes ×105 CFU g-1 as well as Fungi ×105 CFU g-1 as compared to No mulch. Similarly, INM comparing 75% RDF + 25% N through FYM significantly improved the population of Bacteria ×105 CFU g-1, Actinomycetes ×105 CFU g-1 as well as Fungi ×105 CFU g-1 over 100% RDF during both the years, all these practices improved soil fertility, soil health as well soil quality.
