Abstract:

This study was conducted for 2 years in the Ankara ecological conditions during the 2010-2011 and 2011-2012 adulthood periods. The trial parcels divided into random blocks are established in three wheels according to the trial pattern. The test also applied phosphorus doses (0, 3, 6, 9 kg/day) to the main parsels and nitrogen doses (0, 5, 10, 15, 20 kg/day) to the lower parsels. The aim of this study is to determine the effect of different doses of phosphorus and nitrogen in the peanut plant on plant length (cm), side branch number (ad), plant table number (ad), 1000 seed weight (g), fat ratio (%), seed production (kg/day). Depending on the doses of phosphorus and nitrogen; average plant length, table number in the plant, 1000 seed weight, fat ratio, seed production respectively 101.4-179.3 cm, 32.8-44.5 pieces/plant, 16.30-17.20 g, 19.72-20%. It was identified as 60 and 209.4-338.3 kg/day. The highest seed productivity was obtained in the 2010-2011 growing year from the N20 and P9 applications. The highest seed productivity was obtained from the interactions of P6N10 and P9N10. The average fat ratio varied between 19.72-20.60%, and the highest fat ratio was recorded in the application P9. This study has found that different phosphorus and nitrogen doses are an important factor that increases the seed productivity and fat rate in the pellets.
