Abstract
Two field experiments were carried out at Gemmeiza Agricultural Research Station, Gharbia Governorate during two seasons (2008 and 2009) to study the effect of four aminototal concentrations (i.e without, 1g/L, 2g/L and 3g/L) under three N rates (15, 30. and 45 Kg N/fad.) and their interaction on leaf chemical composition, seed and fiber quality of the Egyptian cotton cultivar, Giza 86. Results indicated that the differences between N rates for leaf N content, seed index, protein and oil % were significant, where, lint %, micronaire reading and pressley index were insignificant in the two seasons. Rate of N fertilizer 45 kg N/fad. gave the highest values for leaf N content, seed index, protein and oil %, while, 30 kg N/fad. gave the highest values for leaf k content in the both seasons. Foliar application of aminototal gave a significant effect on leaf N and K contents, seed index, protein and oil %, on the other hand, lint %, micronaire reading and Pressley index were insignificant in the two seasons. Foliar cotton plants with 3g/L or 2g/L concentration from aminototal gave the highest values of most studied attributes. The interaction between N rates and aminototal concentrations were significant for most studied traits except lint %, micronair reading and Pressley index in the two seasons. Also, results show that, fertilization cotton plants with 30 kg N/fad. and sprayed with 2 g/L aminototal improved the fiber and seed quality under the experiment soil conditions.
