Growers often apply high amounts of chemical fertilizer for vegetable production and this application contributes concerns about nitrate levels in food. An experiment was conducted to investigate N soil amendment effects for reducing the nitrate accumulation and improving the quality of fresh purslane (Portulaca oleracea L.). Treatments included four levels of animal manure as follows, N-based broiler litter (T1), P-based broiler litter (T2), N-based cattle manure (T3), P-based cattle manure + urea (T4), four levels of chemical fertilizer equivalent to organic treatments and a T0 (no fertilizer and manure). Results showed that nitrate levels of broiler litter and cattle manure treatments were significantly lower than those of chemical fertilizer treatments. The highest level of nitrate in the first harvest was recorded in the T7 treatment and higher levels were recorded in T5 and T7 treatments in the second harvest. In the first harvest, T1 and T2 treatments had higher apparent quality but in the second harvest, apparent quality of T2 and T5 treatments showed a significant increase compared to the other treatments. It is concluded that organic manure application result in higher quality to inorganic fertilizer but reduces nitrate accumulation in fresh purslane.
