    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) Ekinci, M.B.; Togay, N.; Togay, Y.; Dogan, Y.
    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).
