| Legumes are the largest source of vegetable protein which 18.5% of human protein being supplied by legumes. Molecular nitrogen fixation (N2) by legumes in addition to resolving their needs is very useful for crops that fall in rotation next year. Molybdenum is involved in the activity of enzymes that fix nitrogen. Therefore, in order to investigation effect of molybdenum and nitrogen on yield of two chickpea cultivars, a two-year experiment was performed as factorial split plot based on randomized complete block design at Dryland Agriculture Research Institute, Kermanshah, Iran. The main plots were included two chickpea cultivars (Arman and Adel) and sub plots were consisted of different levels of molybdenum (Mo1 =0, Mo2 =1 and Mo3 =2 Kg. ha-1) as Ammonium molybdate from and nitrogen levels (N1=0, N2=25 and N3=50 kg. ha-1) as urea form which conducted in three replications. The results showed that the effect of cultivar on grain yield, biological yield, straw yield, number of seeds per pod and number of pods per plant was significant (1% Probe). The average yield of Adel cultivar was 924.5 kg.ha-1 that was higher than Arman cultivar with 847.1 Kg. ha-1. The effect of different Amounts of molybdenum on number of pods per plant, leaf nitrogen percentage, number of seeds per pod and nodule weight was significant. In all cases, the highest amount was obtained from 2 Kg. ha-1 of Ammonium molybdate source. The highest grain yield was obtained by application of 50 kg. ha-1 urea as nitrogen source and 2 Kg. ha-1 Ammonium molybdate (1135.8 kg.ha-1) have not significant difference with the treatment of 25 Kg. ha-1 urea and 2 Kg. ha-1 Ammonium molybdate(1088.6 Kg.ha-1). Therefore to reduce fertilizer use, application of 25 Kg. ha-1 urea and 2 kg. ha-1 Ammonium molybdate is recommended to chickpea under rainfed cultivation. |
