Özet:

This study aimed to assess the effects of organic fertilizer applications on yield and some yield components of durum wheat (Triticum durum L.). Field trials were conducted under supplemental irrigation conditions in Harran Plain during the growing seasons of 2014-2015 and 2015-2016. In the experiment, Control+ 6 types of organic fertilizer traitments were tested (ie.1.chicken manure, 2.vermicompost, 3.cattle manure, 4.chicken manure + liquid fertilizer, 5.vermicompost + liquid fertilizer, 6.cattle manure + liquid fertilizer). Combined Analysis of two consecutive years’ data indicated that cattle manure+ liquid fertilizer treatment increased grain yield significantly. In the control application, grain yield was 386,381 kg/da while cattle manure+ liquid fertilizer treatment produced 605, 5476 kg / da grain yield. Among all of the treatments ‘cattle + liquid fertilizer’ treatment produced the highest grain yield (605, 5476 kg/da), 94,13cm plant height, , 6,865 cm spike length,. and 55,41 g weight of thousand kernel ,It was concluded that various organic fertilizer applications increased plant height, spike length and thousand kernel weight compared to control plants while the treatments increased grain yield 50 -56% based on the applied organic fertilizers .
