Abstract

In order to evaluate the effect of different sources and rates of nitrogen on growth and biomass production of PURSLANE, a randomized complete block design was conducted with three replications at the agricultural research farm of Shahrekord University in 2012. Fertilization treatments were consisted of control (no N amendment), 30 and 90 kg N ha-1 in the form of UREA FERTILIZER, 30 and 90 kg N ha-1 in the form of COW MANURE, 60 kg N ha-1 as UREA FERTILIZER+COW MANURE in 2:1, 1:1 and 1:2 ratios. The results showed that the greatest LEAF AREA INDEX was observed from the second cutting with integrated treatments and 90 kg N ha-1 as COW MANURE. In the first cutting, the greatest aboveground FRESH WEIGHT (76.04 Mg ha-1) was obtained from 90 kg N ha-1 as COW MANURE but there was not a significant difference with the integrated treatment (1:1). In second cutting, aboveground FRESH WEIGHT in integrated treatment (1:1) had a significant decline compared to that of the 90 kg N ha-1 as urea and/or COW MANURE. The leaf FRESH WEIGHT from the first cutting was significantly higher than the second cutting. In general, the application of combined organic and chemical fertilizer (1:1) is effective in reducing nitrogen of single cutting of PURSLANE production, and future research should focus on top dressing of nitrogen application for increasing production of the second cutting of PURSLANE.
