TAILIEUCHUNG - Effects of organic manures and non-chemical weed control on wheat. II. Grain quality
Deficit plant nutrients, especially nitrogen, and weed competition are the most critical problems in organic farming. This research was carried out on research plots of the Agricultural Research and Extension Center of Atatürk University Agricultural Faculty during the cropping seasons of 2006–07, 2007–08, and 2008–09 under dry farming conditions. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2013) 37: 271-280 © TÜBİTAK doi: Research Article Effects of organic manures and non-chemical weed control on wheat.

This research was carried out on research plots of the Agricultural Research and Extension Center of Atatürk University Agricultural Faculty during the cropping seasons of 2006–07, 2007–08, and 2008–09 under dry farming conditions. A factorial experimental design with 4 replications was used to set up the experimental plots. The factors were 2 wheat cultivars (Kırik and Doğu-88), 3 weed control practices (weedy control, hand weeding, dense sowing), and 7 fertilizer sources [control, standard inorganic (NP), Bio-Organic (Bio), Bio-SR Organic (Bio SR), Leonardite, Organic fertilizer (OF), and cattle manure (CM)]. Hectoliter weight, crude protein ratio, Zeleny sedimentation value, wet gluten content, number of fall (enzyme activity), and crude ash ratio were investigated as the quality parameters for bread-wheat cultivars. Differences between Doğu-88 and Kırik were significant with regard to the investigated parameters except for hectoliter weight. Kırik was superior in terms of quality parameters.
