The Effect of Different Sowing Dates and Sowing Densities on Some Agricultural Characteristics of Chickpea (Cicer arietinum L.) in Diyarbakır Ecological Conditions

Abstract

This study was carried out in Diyarbakır ecological conditions in 1995-96 and 1996-97 vegetation years. Diyar- 95 chickpea variety was used in the study. In the study, the effects of 5 different sowing times (November 15, December 15, January 15, February 15 and March 15) and 5 different sowing frequency (22.2, 27.7, 33.3, 38.8 and 44.4 plant m-2) on some agricultural properties of Diyar-95 chickpea variety were investigated. The experiment was established with four replications according to the Divided Plots in Random Blocks. In the experiment, sowing times were placed into main parcels and sowing frequencies into sub-parcels. According to the two-year averages, yield per plant for different sowing times was found between 6.81-13.65 g, number of pod was between 16.77-28.56 plant-1, number of seeds per plant was between 14.83-29.00, number of seeds per pod was between 0.89-1.03, biological yield was between 229.7-444.4 kg da-1, harvest index was between 47.58-49.82% and 100 seed weight was between 39.08-41.78 g. For different sowing densities, yield per plant was between 9.00-13.19 g, number of pods per plant was between 19.18-28.36, number of seeds per plant was between 18.25-27.90, number of seeds per pod was between 0.94-0.99, biological yield was between 307.4-400.9 kg da-1, harvest index was between 47.48-49.75% and 100 seed weight was found between 40.03-41.73 g. As a result of the two-year study, it was concluded that Diyar-95 chickpea variety can be cultivated in winter in Diyarbakır ecological conditions and planting with a density of 44.4 plants per square meter would be appropriate for cultivation.
