Correlation and path coefficient analysis for yield and some yield components of wheat (Triticum aestivum l.)
(Scibulcom Ltd., 2017) Togay, Necat; Togay, Yeşim; Doğan, Yusuf
The experiment was conducted to determine the relationship among yield and some yield components using correlation and path coefficient analysis. This study was performed under Mardin conditions the years of 2011–2012 and 2012–2013. Fifteen bread wheat varieties were used in the experiments. The randomised complete blocks design with 3 replications was used. The characteristics such as plant height, spike height, numbers of seed per spike, seed yield, harvest index, biological yield and 1000 seed weight were investigated in the study. Positive and statistically significant (p < 0.01) relationships were determined between seed yield, spike height, numbers of seed per spike, biological yield and harvest index. According to path coefficient analysis, there were strong direct effects of the biological yield and harvest index on the seed yield, p = 0.53549 and 0.548321, respectively. The results of this study indicate that numbers of seed per spike, biological yield and harvest index affected seed yield and it was concluded that these characters should be considered as significant selection criteria in wheat breeding for yield under the regional conditions of southeast Turkey. © 2017, Scibulcom Ltd.

Determination of suitable nitrogen doses for growing second product maize (Zea mays L.) varieties in chickpea planting fields and its economic analysis
(AGRICULTURAL RESEARCH COMMUNICATION CENTRE, 2015) Dogan, Yusuf; Togay, Yesim; Ekinci, Mehmet Behzat; Togay, Necat
The experiment was executed in three repetitions according to “The Split Plots in Randomised Blocks Design” in the 2013- 14 growing seasons. As material; commercial maize varieties Dekalp 5401, Dekalp 5783, Pioneer PR32T83 and Syncero were selected. Three nitrogen doses [0, 150, and 300 kg ha-1 (Ammonium nitrate)] and 80 kg ha-1 phosphorus (P2O5 : TSP: triple super phosphate) were used. According to the two year results, the highest seed yield was obtained with Syncero (9.527 kg ha-1) and Dekalp 5401 (9.491 kg ha-1), the lowest was provided with Dekalp 5783 (823.1 kg ha-1). In terms of the effect of nitrogen doses on seed yield, the highest value was obtained from 300 kg ha-1 application at 10.212 kg ha-1, the lowest value was obtained through the control plot (0 kg ha-1) at 7.844 kg ha-1. The economic analysis, showed that yield level increased as the dose raises. The highest revenue-generating dose was 300 kg ha-1 among the nitrogenous fertilizer applications. In this context, a profit of USD 2.87 was made in return for a cost of USD 1.00. As further doses should be applied for a net determination, it is difficult to estimate if this is the most profitable dose. Under the circumstances, however, it can be stated that the highest profitability is possible through this application (the 3rd).
