Abstract :

This experiment was conducted during 2016 as factorial experiment based on completely randomized block design with 3 replications. The first factor consisted of three levels of naphthalene acetic acid (0, 200 and 400 ppm) and the second factor included three levels of salicylic acid (0, 2 and 4 mM). The results showed growth improvement process in physiological indicators spraying with 200 ppm naphthalene acetic acid and 2 mM salicylic acid was higher, And the least effect on the physiological parameters of growth in the control (without the use of naphthalene acetic acid and salicylic acid). The difference between naphthalene acetic acid levels was significant in terms of plant height, number of pods per plant, number of seeds per pod, 1000 seed weight and grain yield at 1% probability level. The difference between salicylic acid levels was significant in all traits measured at 1% level. In the interaction, 1000-seed weight at the probability level of 5% and grain yield were significant at 1% probability level. the highest grain yield was observed in the interaction of naphthalene acetic acid and salicylic acid with 200 ppm naphthalene acetic acid and 2 mM salicylic acid with 2666 kg ha-1 And the lowest in control treatment (without the use of naphthalene acetic acid and salicylic acid) with 874 kg ha-1. the maximum weight of 1000 seeds In the effect of 200 ppm naphthalenic acetic acid and 2 mM salicylic acid with a weight of 46.8 g and the lowest in the control with 35.4 g. according to these results, application of 200 ppm naphthalene acetic acid and 2 mM salicylic acid increases the morpho-physiological traits and produced components and is also recommended in the region.
