| Abstract | ||||
| Two field experiments were carried out on clay soil in El-Gemmeiza Agric. Res. St., ARC, El-Gharbiya Governorate, during 2016 and 2017 to study the effect of nanofertilizer and N-fertilization levels on productivity of cotton Giza 86 under two sowing dates. The experiment design was a split split-plot. The main plots involved two sowing dates; (Early at 8th April and Late at 8th May). While, the sub plots were allocated to three treatment of nanofertilizer (without, Lithovit 2.5g/L and Lithovit 5g/L). Application three times (at squaring,initiation of flowering and two weeks after flowering). While, the sub sub-plots were allocated to three N-fertilization levels, (50%, 75% and 100% recommended dose). The most important results obtained could be summarized as follows: Sowing date had a significant effect on growth, yield and its omponents. Where, the early sowing date surpassed the late sowing date. The levels of N had significant effect on growth, seed cotton yield and its components in both seasons. The rate of N (75%) gave the good averages in this respect. The Nano-fertilizer by Lithovit had significant effect on growth, seed cotton yield and it compounds. All treatments had a not significant effect on fiber properties. Early sowing date in combination with the N fertilizer (45kg N/fad) and foliar application with Lithovit (5g/L water) for obtaining gave the high productivity of Egyptian cotton variety Giza 86. | ||||
