Response of Some Wheat Varieties to Bio and Mineral Nitrogen Fertilizers

U.A. Abd El-Razek and A.A. El-Sheshtawy

In order to study the effect of Microbin inoculation, different rates of nitrogen fertilizer (45, 90, 135 and 180 kg ha-1) and their interaction on yield and yield components and protein percentage of two wheat varieties (Sakha 93 and Gemmeiza 9) during the two successive growing winter seasons 2010/2011 and 2011/2012 seasons. The experimental design was split B split plot design with three replications, Microbin inoculations were located in main plots and four N rates fertilizers were allocated in the sup-plots and two wheat cultivars were allocated in the sub-sub plots. The highest yield was produced due to application of microbin, also the same trend was obtained with N rate of 180 kg ha-1. Gemmeiza 9 recorded the highest yield compared with Sakha 93. The interaction between bio-fertilizer and N rates proved to be significant for all studied traits. The highest grain yield/ha was found with the interaction between MicrobinxGemmeiza 9. Also, the interaction between 180 kg N ha-1xGemmeiza 9 recorded the highest grain yield ha-1. According to these results, rate of 180 kg N ha-1 and application of microbin as bio-fertilizer using variety Gemmeiza 9 could be recommended for favorable wheat production under the local environmental conditions of this study.
