The effect of two types of bio-fertilizers on the tuber production of potato: (a case study of Damavand area)
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 6
Abstract
Potato third of agricultural production in the country has after wheat and rice. But because of the damage caused by viral pathogens that performance per unit area decreases. The use of biological fertilizers to increase food production, which is one of the world's most important agricultural products. In order to study the effect of bio-fertilizer on the stolon formation stage in mini-tuber production of three potato cultivars, this study was carried on factorial randomized complete block design with two factors including cultivars (Agria, Marphona and Sante) and Bio-fertilizer (no-fertilizer, Azeto-barvar1, Phosphate barvar2 and Azeto-barvar1+Phosphate-barvare2) with four replications. At first the single-node cuttings of three cultivars Agria, Sante and marphona were planted on MS medium. The produced seedlings were transferred to the greenhouse in pots. The levels of bio-fertilizer were preferred at 2.5g/l and were used on the stolon formation stage. Results revealed that cultivars, bio-fertilizers and bio-cultivars-fertilizers interactions had a significant effect at the 1% on yield and yield components of mini-tuber. Bio-fertilizer increased photosynthesis with increasing leaf area and net assimilation rate of light and increased minituber yield.
