Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 20
Abstract
In order to investigate the effect of water deficit and application of different fertilizers on some physiological characteristics of coriander, an experiment was conducted at research field at Khorramabad-Lorestan, Iran in 2009-2011. Field experiment was carried out by split factorial design with 3 replications. The factors studied included two levels of irrigation, irrigation after 30 mm evaporation from evaporation pan (without drought stress condition) and irrigation after 70 mm evaporation from evaporation pan (drought stress condition). Nitrogen levels were N0, N60, N90, N120 kg/ha and phosphorus levels were P0, P80, P100, P120 kg/ha. The result showed that irrigation after 30 mm evaporation (without stress condition) and application of 120 kg/ha nitrogen and phosphorus increased crop growth rate, leaf area index, whereas irrigation after 30 mm evaporation and application of 90 kg/ha nitrogen and 100 kg/ha increased net assimilation rate. The highest crop growth rate, leaf area index was obtained from I30N120P120, and highest net assimilation rate was obtained from I30N90P100.
