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, Y.; Doğan, Yusuf; Ekinci, M.B.; Togay, N.; Togay, 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).
Determining Irrigation Scheduling and Different Manure Sources of Yield and Nutrition Content on Maize (Zea Mays L.) Cultivation
(Corvinus University of Budapest, 2019) Dogan, Y.; Togay, N.; Togay, Y.; Doğan, Yusuf
The aim of this study was to determine the most suitable irrigation schedules and sources of manure for maize under Mardin ecological conditions. For this purpose, four sources of fertilizer and three irrigation schedules were applied in hybrid maize cultivar to find out their effects on the yield and yield factors in the years of 2014 and 2015. The study used a randomized complete block with split block design with 3 replications. In the study, significant differences were determined on traits at the level of 1% and 5%. The plant height, first cob height, cob length, number of seeds per cob, cob yield, 1000 seed weight, seed yield per unit, hectoliter, protein and oil ratio in seed, Mg, K, Fe, Ni, Cu, Zn, Mn, Na, Ca content of seeds were significantly influenced by irrigation schedules and sources of fertilizer for two years. The highest values were obtained from chicken manure with 9646 kg ha-1 in the first year and 11019 kg ha-1 in the second year, whereas the lowest values were obtained from control with 6363 and 6662 kg ha-1 for the first year and the second, respectively. But the difference between 180-80 kg N-P2O5 - ha-1 and chicken manure was not statistically significant in the second year. According to the irrigation schedules, the grain yield ranged between 6386-10678 kg/ha in the first year and 7575-12133 kg ha-1 in the second year. The lowest grain yield per area was from the four-irrigation application, whereas the highest values were obtained from the six-irrigation application. The results of the study showed that grain yield and nutrient level of corn seeds increased, depending on irrigation time and number. © 2019, ALÖKI Kft., Budapest, Hungary.
Effect of Different Sowing Time on Yield and Yield Components of Lentil (Lens Culinaris Medic.) Varieties in Mardin Kiziltepe Conditions
(Univ Namik Kemal, 2014) Doğan, Yusuf; Togay, Y.; Togay, N.
The aim of this work is to determine the most suitable sowing date for lentil in Mardin Kiziltepe conditions. Three cultivars of lentil (Firat-87, Sakar andYerli Kirmizi) were sown at three different sowing dates (November 10, 25 and 10 December). The trial was conducted in the experimental fields of Kiziltepe Vocational High School of Mardin Artuklu University by using split plots in randomized factorial blocks design with the three replicates in years of 2011-12 and 2012-13. Experiment was established as main plots and sowing times treatments as split plots. Effects of sowing dates on plant height, first pod height, numbers of pod per plant and numbers of seed per plant, numbers of seed per pod, 1000 grain weight, grain yield, harvest index and biological yield were investigated for three cultivars. According to the two years results; effects of varieties and sowing time on the yield and yield components of lentil were obtained significantly. While the highest grain yield per area was obtained at the Sakar cultivar as 237.48kg/da and 210.34 kg/da, the lowest grain yield per area was obtained at the Yerli Kirmizi cultivar as 164.07 kg/da and 148.22 kg/da in years of 2011-12 and 2012-13 respectively. The most suitable sowing time was determined with November 25 in Mardin conditions.
Effects of Humic Acid and Phosphorus Applications on Nutrient Composition of Lentil (Lens Culinaris Medic.)
(Scibulcom Ltd., 2016) Togay, Y.; Dogan, Y.; Togay, N.; Doğan, Yusuf
Lentil (Lens culinaris Medic.) is an important food crop with high protein content. This study aimed to determine the effects of increasing doses of phosphorus and humic acid applications on P, K, Ca, Mg, Fe, Cu, Mn, Zn, protein ratio and seed yield in lentil cultivar. The study was carried out in the research and application during the 2008–2009 and 2009–2010 cropping seasons in field of Agriculture Faculty Yuzuncu Yil University, Turkey. The experiment comprised a factorial randomised complete block design replicated three times with three phosphorus treatments 0, 40 and 80 kg ha–1, as triple superphosphate, and three humic acid treatments 0, 300 and 600 kg ha–1. For basic fertilisation 40 kg ha–1 ammonium sulphate were applied for nitrogen. The nutrient contents of seed and yield were significantly increased by increasing phosphorus and humic acid levels except for Zn content nutrient. The combination between phosphorus at 80 kg P2O5 ha–1 and humic acid at 600 kg ha–1 gave the highest growth and production as well as minerals composition (P, K, Ca, Mg, Fe, Cu and Mn) and protein content compared to other treatments. Humic acid increased the availability of phosphors, macronutrients and micronutrients. © 2016, Scibulcom Ltd. All rights reserved.
Nutrient Status and Yield of Chickpea (Cicer Arietinum L.) as Influence by Application of Different Harvest Timing and Sulphur Fertiliser
(Scibulcom Ltd., 2015) Dogan, Y.; Togay, N.; Togay, Y.; Doğan, Yusuf
The objectives of this research were to study the effect of harvesting time and sulphur levels on the yield, protein and mineral nutritional value of chickpea seeds. Three different harvesting times (early, on-time and late) and four sulphur levels (0, 20, 40 and 60 kg ha–1) were used. Yield, protein ratio and mineral nutritional value of chickpea were significantly affected by sulphur and harvest timing. The highest grain yields according to the harvest time were obtained from on-time harvest with 1527 and 1434 kg ha–1 for the first and second years, respectively. The lowest grain yields were obtained from the control plots, whereas the highest values were obtained from the plots given 60 kg ha–1 sulphur. Generally, protein, phosphorus, calcium, magnesium, copper, zinc, and manganese concentrations of the seeds in on-time harvest and 60 kg ha–1 sulphur aplication were found to be greater than in early and late harvested plants. Positive significant relationships were found between harvest time and protein (r = 0.64**), Fe (r = 0.75**) and Zn (r = 0.27*). Positive significant relationships were found between sulphur doses and grain yield (r = 0.44*), protein (r = 0.26*), P (r = 0.71**), K (r = 0.73**), Ca (r = 0.36**), Mg (r = 0.76*), Zn (r = 0.57) and S (r = 0.96*). © 2015, Scibulcom Ltd.
