Abstract
The effect of the application systems of K2SO4 and foliar application of micronutrient mixtures levels on growth, yield and quality of cassava (Indonesian, cv) was studied at Experimental Farm of South Tahrir Horticulture Research Station, at Ali Mubarak Village, EL-Bostan region,  Behera, Egypt during 2012/2013 and 2013/2014 seasons. The experimental design used was the split plot system in randomized complete block design with 3 replications. Cassava plant that receiving five equal doses of K2SO4 gave the highest values of  plant height, number of leaves and number of branches plant-1, root weight, root length, root diameter, total yield plant-1 and total yield fad-1, as well as tuberous root dry matter, root starch, and total sugar of root. The results also showed that, increasing of the micronutrients mixture levels concentrations up to 30 % were gradually increased the productivity of cassava plants. In addition, tuberous root quality; dry matter %, starch %, and total sugar as well as elements contents; N, K, Zn, Mn, Fe and Cu showed positive response to various micronutrients mixtures levels. The combination treatment application system of K2SO4 at five equal doses + foliar application of micronutrient mixture levels at the rate of 20 or 30 % gave the highest values of  vegetative growth, total tuberous root yield (kg plant-1and ton fed-1), tuberous root quality and chemical constituents characters of cassava plants.
