Production of mungbean (Vigna radiata L.) as affected by nitrogen and phosphorus fertilizer application

Abstract

In order to investigate the effects of different nitrogen and phosphorus levels on yield and yield components of mungbean variety Partow a field experiment was conducted at the Research Farm of the Islamic Azad University of Shahrerey, in Tehran, Iran in 2009. The experiment was laid out with factorial arrangement in a Randomized Complete Block Design with three replications. Five levels of nitrogen (0, 30, 60, 90 and 120 kg N ha-1) and six levels of phosphorus (0, 30, 60, 90, 120 and 150 kg P2O5 ha-1) were the treatment variables. Results showed that application of N and P fertilizers significantly increased the seed yield. The maximum seed yield (224.2 g m-2) was obtained when 90 kg N ha-1 and 120 kg P2O5 ha-1 was applied. This increase in seed yield was mainly due to more number of pods plant-1, number of seeds pod-1 and 1000 seeds weight. Thus, application of 90 kg N ha-1 and 120 kg P2O5 ha-1 seems to be optimum levels for harvesting highest yield of mungbean. © 2010 Asian Network for Scientific Information.
