Nitrogen levels and application methods affect weed biomass, yield and yield components in Tir’ wheat (Triticum aestivum)

Comparison of Grain Yield and Some Characteristics of Hulled, Durum and Bread Wheat Genotypes Varieties

“…Because of this significant increase, second year's averages were found to be higher. Compared to previous studies (Togay et al, 2009), the biological yield of hulled wheat was considerably higher than the Turkey average. The amount of precipitation during blooming and grain filling, which was much higher than the average in the second year, caused extra development in vegetative parts especially in hulled wheats.…”

“…However, the yield obtained in the second year of our study was higher (2533 kg ha -1 ). Although it was reported in previous studies that the grain yield of Tir wheat varied between 650kg ha -1 and 1570kg ha -1 (Togay et al, 2009), the first year of our study produced much higher yield (2922 kg ha -1 ). Mean annual temperature, humidity and precipitation values in the years of experiment were higher than the long-term average.…”

“…Compared to the first year of the experiment, the second year produced lower protein contents. The grain protein content of Tir wheat was around 12%-14% in other studies conducted with nitrogen treatment (Togay et al, 2009) but higher in our study (14%-15%). In Emmer populations, however, protein content varied between 6.7% and 18% (Blanco et al, 1990;Kaplan et al, 2014).…”

An original and efficient fertilizer for cherry tomato plants grown in urban agriculture: Feral pigeon guano

“…Our results, therefore, confirm that the pigeon guano constitute an efficient local fertilizer that could be used in urban agriculture. In agreements with our results, Togay and Ozalp (2015) report that pigeon manure provide the best yield on wheat compared to chicken manure, sheep manure, municipal sewage sludge, and certificated organomineral fertilizer.…”

“…Previous works showed that the guano of seabird could be an efficient fertilizer for some plants but not for others (Young et al, 2011). It is the same for pigeon guano which is, for example, a good fertilizer for wheat (Togay & Ozalp, 2015), but not for potatoes (Al-Moshileh & Motawei, 2007). It would also be interesting to test the use of other substrates (i.e., soil) than the one used here or to study the leaching of the nutrients present in guano.…”
