farm yard manure application of potato (Solanum tuberosum var. Agria) with tree level of nitrogen fertilizer
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 6
Abstract
To investigate the effects of nitrogen fertilizer and Farm Yard Manure (FYM) on the characteristics of potato crop, an experiment was performed in split plots within completely randomized blocks during the crop year 2012-13 in a farm- dashte-mir Farm located 20 kilometers far from Kkhodabandeh, Iran. The experiment was made in three replications for each of them FYM at three levels , controlled , 20 and 40 t/ha and nitrogen fertilizer derived from urea at four levels , controlled , 100, 200 and 300 kg/ha . The obtained results revealed that the treatment of 40 t/ha of FYM on the tuber hight, average yield and nitrogen escape percent respectively with the values of 9.294 (cm), 34,040 kg/ha and 0.865 (%) were significant in the level of 0/01%, (P<0.01) . It is also proved to be significant in the level of 0/01% and have the most values for the treatment effect of 300 kg of nitrogen fertilizer on plant height (59.55 cm), stem dry weight (100.0 g),tuber hight (6.168 cm), nitrogen scape percent (0.875%), average yield (26,900 kg/ha) and soluble sugars percent (1.943%). The investigation of the interaction effect of FYM and nitrogen fertilizer on potato proved to show no significant differences between the mentioned treatments and the measured characteristics except for soluble sugars percent (2.300%) . The 40 t/ha of FYM and 300 kg nitrogen fertilizer resulted in 117.9 (g) of stem dry weight, 70.11 (cm) of plant height, 10.81(cm) of tuber height, nitrogen scape percent (1.964%) and 5.8 number of tuber per pland and Furthermore, the 40 t/ha of FYM and 200 kg nitrogen fertilizer resulted in the average yild (40080 kg/ha). The results obtained from the experiment prove that it is necessary and inevitable to use FYM in order to achieve the highest performance and to protect the soil from degradation.
