Effects of Different Plant Densities and Sowing Methods on Yield and Some Yield Components of Some Chickpea (Cicer arietinum L.) Cultivars in Van Ecological Conditions

This study was carried out to determine the effects of various plant densities and sowing methods on yield and yield components of some chickpea (Cicer arietinum L.) cultivars with three replications at split split plot design in randomized blocks in Van conditions in 2009 and 2010. In the study, three different varieties of chickpea (Aziziye-94, ILC-482, and Canitez-87) were used as plant materials. Three chickpea cultivars were sown in three different sowing densities (35, 50 and 65 seeds m-2) and four sowing methods (broadcasting to seeding depth, to the rows, contrary rows with 90°, and contrary rows with 45°). In the study, seedling emergence time, plant number m-2, plant height, first pod height, number of branches, number of pods per plant, seed number per pod, seed number per plant, 100 seed weight, harvest index, grain yield per unit area and the crude protein content were determined .At the end of the study, the highest grain yields per unit area in 2009 and 2010 were obtained from broadcasting to seeding depth method as 104.6 and 158.6 kg/da from ILC-482 cultivar with the densities of 50 seeds m-2 and from contrary rows with 90o method as 158.6 kg/da from ILC-482 cultivar with the densities of 50 seeds m-2 respectively. The lowest grain yields per unit area in 2009 and 2010 were obtained from sowing to the rows method as 65.3 kg/da from Can？tez-87 cultivar with the frequency of 35 seeds m-2 and from sowing to the rows method as 111.8 kg/da from Aziziye-94 cultivar with the densities of 35 seeds m-2, respectively
