Abstract
Two field experiments were conducted in both 2000 and 2001 summer seasons at Sakha Exper. Station to study the effect of some nutritional treatments on cotton plant growth (var. Giza 86), seed cotton yield, lint percent, oil content of seeds, protein content of kernel seeds and the net return. The treatments included N, P, K, micronutrients (coatengien) and 3 biofertilizers being, Nitrobien, Phosphorine and Rhizobacterien such products are produced by the General Organization for Agriculture Equalization. These products were examined in combination with half recommended dose of NPK in order to improving seed cotton-yield, quality, reducing the required mineral fertilizer by about 50%, increasing the highest net return and protect the agroecosystem from pollution. The obtained results reveal that: Each of the tested biofertilizer and micronutrient treatments could compensate more than one half the NPK need of cotton plant accompanied with a notable yield increased. The balanced fertilization including micronutrients (Fe: Mn: Zn) used as coating and macronutrients (NPK), could increase the NPK fertilizers efficiency, obtaining high seed cotton yield under both NPK levels and increase lint percent, plant height, No. of open bolls/plant and boll weight. The study showed the vital importance of soil analysis, which have low levels of available N, P, K and some micronutrients it must be fertilized with the economically beneficial amounts of these nutrients, when we cropped with cotton. Protein, oil content in seeds and N, P & K content of cotton fully developed leaves at the beginning of flowering stage were increased by 1/2 NPK (35 - 15 + 12 kg/fed.), micronutrients (coatengien) and biofertilizers (Nitrobien, Phosphorine and Rhizobacterien) applications. The highest cotton seed yield and net return were obtained by full cofertilization with N70P30K24 and N3SP1SK12 + biofertilizer (a + b + c) and micronutrients (coatengien). These clearly confirmed that the biofertilizer treatments could be used under the Egyptian conditions as effective tool to compensate the quantities of used the chemical fertilizers and consequently reduce the consumption of these fertilizers which turn minimizing the agricultural costs as well as the Egyptian environmental pollution.
