| Abstract | ||
| Study on effects of nitrogen starter and spray fertilizer application differences on chickpea genotype and varieties was carried out. In order to do this study, experiments were carried out with 12 treatments including factor A chickpea a1 = ILC482, a2 = Azad, a3 = Arman and factor B is methods and levels of nitrogen fertilizer rates b1 = without of N fertilizer, b2 = 20 kg/ha N at the planting time as a starter, b3 = 2% and b4 = 4%, N spraying at the flowering time with factorial randomized complete block design (RCBD) with three replications from 1391 to 1393.The results showed that checkpea genotypes and varieties were significantly different at nitrogen application methods and rates. Genotype ILC482 had heights (1191 kg/ha) and Arman had lowest grain grain yield (994 kg/ha) at nitrogen methods and rates. Chickpea genotypes and varieties indicated that genotype ILC482 with 77 kg/ha, Azad variety with 165 kg/ha and Arman variety with 159 kg/ha increase differently chickpea yields at 20 kg/ha N application. N starter application of 20 kg /ha increased grain yields of check pea genotype and varieties compared to No nitrogen application. Arman variety with 2% spraying N fertilizer produced higher grain yield compare to other nitrogen treatments . It can be concluded that chickpea genotype and variety produced grain yields differently at different methods of nitrogen applications. ILC482 and Azad by nitrogen starter application and Arman by spray N application can increase chickpea grain yield differently. | ||
