Abstract

A field experiment was carried out in El-Gemmeiza Agric. Res. St., ARC, El-GharbiyaGovernorate, during 2016 and 2017 seasons to study the effect of potassium silicatemineral or organic and different NPK fertilizer levels on growth and productivity of Egyptiancotton variety Giza 86 under different sowing dates. The experiment design was a split plotwith four replications. The main plots had two sowing dates; (Early at 8th April and Late at 8thMay) and the sub plots had nine treatments (1- 100% NPK Control, 2- 100% NPK + potassiumsilicate mineral, 3- 100% NPK + potassium silicate organic, 4- 125% NPK, 5- 125% NPK +potassium silicate mineral, 6- 125% NPK + potassium silicate organic, 7- 75% NPK, 8- 75%NPK + potassium silicate mineral and 9- 75% NPK + potassium silicate organic).The most important results obtained could be summarized as follows:1) Sowing date had a significant effect on growth, earliness, seed cotton yield and its components,where, the early sowing date surpassed the late sowing date.2) The levels of NPK 125% + foliar with potassium silicate organic sprayed three times atsquaring, initiation of flowering and two weeks after flowering had significant effect ongrowth, seed cotton yield/fad and its components.3) The interaction between sowing dates, NPK fertilizer levels with potassium silicate treatmentshad only significant effect on plant high and no. of sympodia/plant.4) All treatments (sowing dates, levels of NPK 125% + foliar with potassium silicate and theinteraction) wave exhibited any significant effect on all fiber properties.Generally, from the results obtained revealed that early sowing date in combination withthe NPK fertilizer (125%) and foliar with potassium silicate organic sprayed three times atsquaring, initiation of flowering and two weeks after flowering for obtaining gave the highproductivity of Egyptian cotton variety Giza 86 in clay loam soil.
