Effect of organic and bio-fertilization on potato productivity
New Medit, vol 11, n.4, suppl. (December 2012), pp. 66-68
A field experiment was conducted during the two summer seasons of 2009 and 2010 in sandy soil on potato “Sante” to study the effect of using 100% compost (15 t/fed.) and 50% compost + nitrogen fixing bacteria (Azotobacter, and Pseudomonas alone or together) on potato growth and yield as compared to the conventional mineral fertilization (120-75-150 kg/fed. NPK + 5 t compost/fed). No significant differences in tubers yield per plant and per hectare were detected between mineral fertilization (T1) and using 100% compost (T2); however, “T1” significantly produced a high yield per hectare than using 50% compost + any biofertilizer treatment.
