| Abstract: | An experiment was conducted to assess the effect of different extraction of compost extracts on pak choi (Brassica rapa cv. chinensis) under two fertilizer regimes. Aerated compost extract (ACE) and non-aerated compost extract (NCE) were prepared and all treatments (ACE + organic fertilizer, NCE + organic fertilizer, ACE + inorganic fertilizer, NCE + inorganic fertilizer) were conducted in randomized block design. Soil microbiological analysis after treatment was done. Plants grown with ACE + inorganic fertilizers yielded maximum in fresh, dry weight, and N mineral content compared to others. Plants receiving NCE + organic fertilizers produced a higher phenolic content, whereas antioxidant capacity was observed maximum at NCE + inorganic fertilizers. Soil microbiological analysis significantly increased in yeast and nitrogen fixing bacteria count at ACE + organic fertilizers. The co-application of inorganic fertilizers and compost extract had a significant effect on vegetative growth, quality of the pak choi, and soil fertility. |
