tailieunhanh - Microbial population and soil health under organic cotton production system

A field experiment was carried out at MARS, University of Agricultural Sciences, Dharwad during Kharif, 2010 -11 and 2011-12 to study the “Nutrient management options for sustainable organic cotton production” The results of the two years pooled data revealed integrated application of EC (1/3) + VC (1/3) + gliricidia GLM (1/3) equivalent to RDF with foliar spray of panchagavya @ 5% recorded significantly available soil N, P2O5 and K2O (284, , 330 kg ha-1 , respectively), soil organic carbon ( g kg-1 , respectively), bacteria ( cfuX106 /g of soil), fungi ( cfuX103 /g of soil), actinomycetes ( cfuX102 /g of soil), N2-fixers ( /g of soil), P-solubilizer ( cfuX103 /g of soil), phosphatase ( pnpTPF/g of soil/hr) and dehydrogenase enzyme activity ( µg TPF/g of soil/day) and soil respiration rate ( mg of CO2/hr/100 g soil) over FYM @ 5 t ha-1 + RDF. | Microbial population and soil health under organic cotton production system
