In order to study the effects of nitrogen and boron elements on quantity and quality characteristics of karela (Momordicacharantia L.), a factorial experiment based on the randomized complete block design with three replications was conducted in AgricultururalFaculty, Shahrood University of Technology. The treatments consisted of nitrogen as a first factorin in three levels(75, 150 and 225 kg ha-1,as urea) and foliar application of boron as a second factor in four levels (0, 1, 2 and 3 g L-1 boric acid). The results showed that the maximum amount of the phosphorus in fruit was obtained at the 75 kg ha-1. The results showed that foliar application of boron up to 2 g L-1 caused the greatest effect on the number of flowers per plant (96.46), number of perfect seeds per fruit (36.36), and reducing the number of hollow seed fruits (2.07) and increased the amount of nitrogen (11.10%) in the fruit tissue. The highest fruit yield per plant and seed thousand weight were obtained at the 150 kgha-1nitrogen and 2 gr/l foliar application of boron and the lowest of these traits were treated of 75 kg ha-1 and without application of bororn. Results showed that use of 150 kg ha-1 nitrogen fertilizer plus 2 g L-1 of boric acid, had a greater effect on the fruit yield and concentration of mineral elements in karela fruit.
