EFFECT OF BIO-FERTILIZATION ON YIELD OF POTATO CULTIVAR MARFONA
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 2
Abstract
In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150 and 50+200 g.ha-1 as a second factor. The results showed that the effect of Nitrocara fertilizer on tuber number, dry weight of tuber, tuber yield, tuber weight with lower than 35 mm diameter, tuber weight with 35-70 mm diameter, tuber weight with higher than 70 mm diameter was significant. The highest and the lowest amount of these traits were achieved for 440 mg.L-1Nitrocara and control, respectively. Effect of Nitroxin+Phosphate on tuber number, dry weight of tuber and tuber yield was significant and the highest and the lowest amount of these traits were recorded for 200- 50mg.L-1Nitroxin+ Phosphate and control, respectively. Interaction of Nitrocara× Nitroxin+Phosphate was significant for tuber dry weight, tuber yield, tuber weight with lowers than 35 mm diameter and tuber weight with 35-70 mm diameter. The highest and the lowest tuber dry weight, tuber yield, tuber weight with lowers than 35 mm diameter and tuber weight with 35- 70 mm diameter were obtained for dual application of 440 ml.ha-1Nitrocara with 200-50mg.L- 1Nitroxin+ Phosphate and control, respectively.
