Investigation of the Effect of Different Phosphorus and Nitrogen Doses Applied to Bean (Phaseolus vulgaris L.) Plant on Vegetative Characteristic and Grain Yield

Abstract

This study was carried out in Kahramanmaras conditions in 2020 in order to determine the effects of different phosphorus and nitrogen doses on the vegetative characteristics and grain yield of Goksun bean variety. Four different doses of nitrogen (0, 4 , 8, 12 kg da-1) and four different doses of phosphorus (0, 3, 6, 9 kg da-1) were used in the experiment. In the conducted research, flowering day duration, first pod height, plant height, number of branches, maturation day time and grain yield per decare of bean plant were investigated. According to the results of the analysis of variance, different phosphorus and nitrogen applications during the flowering day and the interactions of these applications with each other were found to be insignificant. As the nitrogen dose increased, the first pod height, plant height and number of branches increased, and the nitrogen dose was found to be important at the rate of 1% for these characteristics. Phosphorus doses applied for the same properties did not make a significant difference. It was determined that different doses of phosphorus and nitrogen applied to Goksun bean cultivar did not make a statistically significant difference on maturation day time. The lowest grain yield was obtained from the application of 171.561 kg da-1 to 0 kg da-1 nitrogen dose, the highest grain yield was obtained from the application of 254.025 kg-1 to 8 kg -1 nitrogen dose. Grain yields obtained from different doses of phosphorus (0, 3, 6, 9 kg da-1) varied between 191.682 – 237.641 kg da-1 . Different phosphorus dosage applications did not make a statistical difference in terms of grain yield. In the study carried out, the highest grain yield was obtained as 288.124 kg da-1 from the interaction of 8 kg da-1 nitrogen application and 6 kg da-1 phosphorus application.
