Response of Maize to Mineral Nitrogen and Bio- Fertilization

TWO FIELD experiments were carried out during the summer seasons 2013and 2014 at the Experimental Farm of Sakha Agricultural Research Station to study the physiological attributes, yield and yield components of maize as affected by bio and mineral nitrogen fertilizers. The applied experiment was designed as complete randomized block design with four replications. The experiment included 10 treatments:60 kg N/fed.+ Cerealin (C), 60 kg N/fad.+ Microbien (M), 60 kg N/fad. + Rizobacterien (R), 80 kg N/fad. + Cerealin (C), 80 kg N/fad. + Microbien (M), 80 kg N/fad.+ Rizobacterien (R), 80 kg N/fad.+ Cerealin (C), 100 kg N/fad.+ Microbien (M), 100 kg N/fad.+ Rizobacterien (R) and 120kgN/fad. Grain maize (hybrid S.C.128 ) were sown in 14 and 16 July in both seasons. The results revealed that, application of 100 kg N+ bio-fertilizers Rizobacterien caused a significant increase in most studied characteristics in both seasons. This can greatly benefit farmers in an area where supply of nitrogen fertilizer is low and cases where farmers cannot afford the cost of high fertilizer input reduced the use a of chemical fertilizer and reduce the harmful effect on human health.
