Effects of Chemical and Organic Fertilizers on Nitrogen and ‎Phosphorus Efficiency in Purslane (Portulaca oleracea) ‎

Abstract

To investigate the effect of nitrogen and phosphorus nutrients from organic and chemical fertilizers sources, on their efficiency in purslane, a field experiment based on complete randomized block design was conducted at the Research Farm of Shahrekord University in 2014. Treatments were 13 t.ha-1 broiler litter (T1), 14.4 t.ha-1 broiler litter (T2), 39 t.ha-1 cattle manure (T3), 16.8 t.ha-1 cattle manure + 150 kg.ha-1 urea (T4), four chemical fertilizer levels equivalent to organic manure treatments, 260+86 kg.ha-1 urea +triple super phosphate, respectively (T5), 287+100 kg.ha-1 urea + triple super phosphate, respectively (T6), 260+200 kg.ha-1 urea + triple super phosphate, respectively (T7), 260+100 kg.ha-1 urea + triple super phosphate, respectively (T8) and control (T0). The results showed that T2 treatment produced 8345 kg.ha-1 of dry matter as compared with those of other fertilizer treatments (P
