Efficacy of organic compost soil on improving yield and quality of mustard green (Brassica juncea L.)

Increasing organic matter in soilf resulted effectively in increasing crop yield, increasing the quality of agricultural products, improving soil fertility, and being environmental friendly. Rich organic soil was an important source in urban agriculture, in the Mekong Delta. The objective of this study was to use agricultural by-products to compost bio- organic-rich soil by combining with beneficial microorganisms to help improve crop yield for growing vegetables in urban agricultural production. The experiment planting mustard green was ranged in completely randomized with three mixing formulas to create bio-organic compost soil combined with NPK inorganic fertilizer (four levels: 0%, 25%, 50% and 100% as recommended). The results showed that the bio-organic compost soil (2) includes 30% pond bottom mud + 35% rice husk + 35% coco peat + 5 mL kg-1 beer residue and bio-organic-rich soil (3) 30% bottom mud soil pond + 35% rice husk + 35% coco peat + Bacillus subtilis 108 cfu.g-1 resulted in increasing the content of available nitrogen, available phosphorus, and exchangeable potassium compared to control organic-rich soil (1), without adding beer residue and beneficial microorganisms. Comparing three types of composted organic soil, bio-organic-rich soil (3) significantly increased mustard green yield compared to organic-rich soil (1) and (2). Applying bio-organic compost soil (3) with an amount of 10 tons.ha-1, without NPK inorganic fertilizer led to increase highest vegetable yield (P < 0.05). Meanwhile, amendament of bio- organic compost soil (2) and (1) needs to be combined with 25% and 50% of the recommended NPK fertilizer to achieve equivalent mustard green yields. The Nitrate content in vegetables in bio- organic-rich soil treatments combined with 25-50% NPK fertilizer is below the threshold affecting health.
Activated carbon production from coconut husks: Laboratory study its ability to treat iron (II) in water
