Field evaluation of mechanized wheat planters in saline lands of Shadegan city

The aim of this study was to compare three types of wheat planters in wheat production in saline lands of the study area.This study was conducted as a randomized complete block design with three replications in the crop year 2020-20211400 in agricultural lands of wheat cultivation in Shadegan region of Khuzestan province. Experimental treatments included three types of wheat cultivators (1- flat planter with grain drill 2- planter on beds3- grain drill-furrower) which were applied on bread wheat of Chamran 2 cultivar.The obtained results showed that the studied traits were affected by different planting methods. Based on the average comparison results, it was observed that the highest number of sprouted seeds with an average of 400 seeds per unit area was related to the flat sowing method with linear work, which had a significant advantage over other sowing methods. Among the grain yield components, it was observed that the highest 1000-seed weight was related to atmospheric floor planting method with an average of 34 grams and the lowest 1000-seed weight with an average of 28 grams was related to ridge planting method. In terms of grain yield, it was observed that the highest grain yield with an average of 2273 kg / ha was related to atmospheric floor planting method. Comparison of mean traits showed that the highest planting depth was related to planting on the ridge with an average of 42.7 mm, which in this regard had a statistically significant advantage over the other two treatments.
