The plant growth and production from swine farm wastewater usage
The plant growth and production from swine farm wastewater usage

The usage of wastewater from swine farm for agriculture have study on the production of three plants such as shallot (Allium ascalonicum L.) marigold (Tagetes erecta L.) and ruzi grass (Bachiaria ruziziensis). The experiment was focusing on the growth production and metals accumulation (Pb Cu Fe Zn) in plant. The results shown that swine farm wastewater were a lot of organic substant and nutrient. The biological oxygen demand and chemical oxygen demand were out of standard. The heavy metals lead zinc copper and iron were amount 0.106 0.218 0.082 และ 0.866 mg/kg respectively. The productivity of shallot and ruzi grass were high growing that treated by swine farm wastewater. The marigold production (flower size dry weight and fresh weight) treated by swine farm wastewater found that were not significant from the marigold production that treated by control water. The amount of lead in shallot ruzi grass and marigold flower were out of standard. The shallot and ruzi root found the amount of zinc out of standard. The amount of copper and iron were not out of standard all three plant.

The used of bamboo residues from chopstick production for mushroom cultivation material
The used of bamboo residues from chopstick production for mushroom cultivation material

Bamboo sawdust from chopstick production process was used as substrate for Indian oyster (Phoenix mushroom) cultivation. Experimental studies in cultivation material including wood sawdust bamboo sawdust and fermented chopped straw for 4 experiments - first experiment used 100 % of wood sawdust the second experiment used 25 % of bamboo sawdust mixed with 75 % of fermented chopped straw the third one used 50 % of bamboo sawdust mixed with 50 % of fermented chopped straw the forth one used 75 % of bamboo sawdust mixed with 25 % of fermented chopped straw and the last one used 100 % of bamboo sawdust. All experiments were analyzed for chemical properties nutrients in substrates for mushroom growing and yield of mushroom. The results showed that each type of mushroom substrate with different humidity. pH is suitable for use as a mushroom cultivation material. For quantity of nutrients in bamboo sawdust is more than wood sawdust. Increasing of nutrients is depending on increase fermented chopped straw. For mycelia growth in wood sawdust were faster than a bamboo sawdust culture. Yield of Indian oyster (Phoenix mushroom) found in any treatments. Especially in experiment 3 (50 % of bamboo sawdust mixed with 50 % of fermented chopped straw) is more suitable for Indian oyster (Phoenix mushroom) cultivation which compared to the other treatments because of highest yield mushrooms (175.11 grams per piece).
