TAILIEUCHUNG - Response of popcorn (Zea mays Everta) to nitrogen rates and plant densities

The objective of this study was to evaluate grain yield and yield components of popcorn with different nitrogen rates and plant densities. Field studies were conducted in 1995 and 1996 at Kazova Plain in Tokat. The experiment was designed in a randomized-complete-block design with a split-plot arrangement with three replications. | Turk J Agric For 25 (2001) 15-23 © TÜB‹TAK Response of Popcorn (Zea mays everta) to Nitrogen Rates and Plant Densities Sabri GÖKMEN, Özer SENCAR, Mehmet Ali SAK‹N Gaziosmanpafla University, Faculty of Agriculture, Department of Field Crops Tokat-TURKEY Received: Abstract: The objective of this study was to evaluate grain yield and yield components of popcorn with different nitrogen rates and plant densities. Field studies were conducted in 1995 and 1996 at Kazova Plain in Tokat. The experiment was designed in a randomized-complete-block design with a split-plot arrangement with three replications. The treatments comprised six levels of nitrogen (0, 50, 100, 150, 200 and 250 kg N / ha) and four plant densities (, , and plants / m2). Nitrogen rates were in the main plots, and planting densities were in the sub-plots. An open pollinated was used as the material in the experiment. In general, significant differences were determined in the investigated plant characteristics. Plant height tended to increase as the nitrogen rate increased. The tasseling period was reduced as the nitrogen level and sowing density increased. The maximum ear length was obtained from low planting densities ( and plants / m2). The number of kernels per ear was not affected by nitrogen application or population density. The 1000-grain weight increased with N application and decreasing plant density. Nitrogen application and plant densities had positive effects on the grain weight per ear. Nitrogen significantly increased the grain yield, but there were no significant differences in yield at the doses of 100, 150, 200 and 250 kg N / ha. The highest grain yield was obtained from plants / m2 when averaged over two years. Our findings indicate that, for maximum grain yield of popcorn, 100-150 kg N/ha should be applied, and the plant density should be plants / m2.
