Evaluation appropriate Chickpea direct seeder in wheat rotation under dryland conditions

In order to select a suitable planter for the direct planting of chickpeas in wheat rotation, eight planters belonging to different companies were compared in a completely randomized block design with five replications for one crop year. The planting operation was carried out in mid-November on land that was under wheat cultivation last year. In order to compare the efficiency of direct planters, traits such as soil displacement by furrower, maximum depth of furrower effect, uniformity of planting depth, uniformity of horizontal distance of seeds, quality of passage of crop residues through furrowers and soil shedding rate were studied. The collected data were analyzed by using SPSS program and then the means were compared by LSD statistical method. The results showed that the treatment (type of planters) had a significant effect on the uniformity of horizontal seed distribution, tillage depth under seed, furrow displacement and yield with 95% confidence and on the characteristics of uniformity of planting depth and residual passage quality with 99% confidence. In terms of uniformity factor, the horizontal seed distribution coefficient is observed, PARS2211/13 with 92% and NT/GM225 with 90% were superior to other planters. In terms of planting depth uniformity, the best result was observed in SINA II planter with 93%. HOSAINI 15 and PARS2211/13 planters were superior to others in terms of the passage of plant debris through the furrowers. DIAMOND planter at 7.4 cm was the lowest amount of displacement among all planters. PARS2211/13 with 1009 kg/ha had the highest yield.
