INFLUENCE OF POTASSIUM SULFATE APPLIED IN CALCAREOUS SOIL AT NUBARIA ON FABA BEAN YIELD AS WELL AS SOME CROP AND TECHNOLOGICAL PARAMETERS
Abstract: Faba bean cv. (Nubaria 1) was grown during the two consecutive seasons (2007/08 and 2008/09) in calcareous soil at Nubaria Research Station. Four potassium sulfate application (48% k2So4) at the rate of 50 kg./fed. at different plant stages were used. This investigation was conducted to study the effect of potassium sulfate fertilizer on growth, yield and improve the nutrition value of faba bean under calcareous soil at Nubaria Research Station. Addition of So4 at the beginning of flowering stage significantly increased seed yield and its components. Potassium sulfate gave the highest level of protein content and lowest level of total carbohydrates when added after 3-4 weeks of planting. Adding So4 twice (after 3-4 weeks of sowing + at the beginning of flowering stage) had the highest ash content and the lowest fiber content. Potassium sulfate fertilizer caused slim increase in lysine, throenine, cyctine and methionine. Also potassium sulfate fertilizer causes increment in glycine amino acid and agrinine. It could observed increment in potassium, phosphorus and iron content compared with control. On the other hand kSo4 decreased molybdenum content and there were some reduction in total vicine content in green seeds. Potassium sulfate fertilizer improved faba bean cookability.
