Effects of nitrogen fertilizer and plant density on yield characteristics of potatoes (CV. Sante) in shazand
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 4
Abstract
In order to study the effects of nitrogen fertilizer and plant density on yield characteristics of potatoes (CV. Sante), an experiment was conducted in summer of 2013. The experimental design was factorial based on randomized complete blocks design with four replications. In this experiment, densities were in 80, 100 and 130 thousand plants in ha and nitrogen fertilizer was tested at four levels (Nitroxin, Nytrazhyn, Azotobacter and urea). After harvesting potatoes on number of tubers per plant, tuber weight, tuber yield, harvest index, density and percent nitrogen gland tubers were measured and the results of analysis of variance. The results showed that the density and type of nitrogen fertilizer was significant on all traits. The density of 80 thousand plants per hectare than other treatments were superior in many characteristics between the treatments of different types of nitrogen fertilizer urea fertilizer for most traits were statistically significantly better. Also, in different types of nitrogen fertilizer urea fertilizer was better statistically significantly for most traits. The interaction between plant density and nitrogen fertilizer were statistically significant for most traits. so most of the potato tuber yield (4584.9), the density of the tuber (1.44 cm3) and harvest index (56.33) was conducted from application of urea and planting 80 thousand plants per hectare. Therefore it is suggested to use density of 80 thousand plants per hectare and application of urea fertilizer in this study has shown the best results. Also yield difference between 80 and 100 thousand plant density was not significant in any of the applied fertilizers.
