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 concentration (i.e without, 1g/L, 2g/L and 3g/L) under three N (15, 30. and 45 Kg N/fad.) and their interaction on leaf chemical composition, yield and yield components of the Egyptian cotton cultivar, Giza 86. Results indicated that the differences between N rates for leaf N content, number of fruiting branches / plant, plant height, number of flowers and bolls / plant, earliness %, boll weight , seed cotton yield per plant and per fad. were significant in the two seasons, where, boll setting % and boll shedding % were significant in the first season only. Rate of N fertilizer 45 kg N/fad. Gave the highest values for leaf N content, number of fruiting branches per plant and plant height, where, 30 kg N/fad. Gave the highest values for leaf K content, number of flowers and bolls per plant , boll weight, seed cotton yield / plant and per fad., on the other hand, 15 kg N/fad gave the best values for earliness % in the both seasons. The differences between 45 kg N/fad and 30 kg N/fad. were insignificant for all studied traits in the both seasons. Foliar application of aminototal gave a significant effect on leaf N and K contents, number of fruiting branches per plant, plant height, number of flowers and bolls per plant, boll weight, seed cotton yield per plant and per fad. on the other hand, earliness %, boll setting and boll shedding % were insignificant in the two seasons. Foliar cotton plants with concentration of 3 or 2g/L from aminototal gave the highest values of most studied attributes. The differences between 2g and 3g/L aminototal were in significant of all studied traits.The interaction between N rates and aminototal concentration were significant for all studied traits except earliness % in the two seasons. Also, results show that, fertilization cotton plants with 30 kg N/fad. and sprayed with 2g/L aminototal increased the yield and yield components under experiment soil conditions.
