Abstract
A field experiment was conducted in Ali Moubarak experimental farm at EL-Bostan Reclaimed Soil Seder (100 km north west of Cairo) where the soil is normal sandy soil irrigated with drip irrigation to study the influence of 3 or 6 tons of town-refuses compost applied with either 25 or 50 kg K20/fed on soil properties as well as yield and some yield components of groundnut plants along with their uptake of macronutrients (N, P and K) and micronutrients (Fe, Mn and Zn). The obtained results could be summarized as follows: In 1-5 soil extract, soluble salts were generally very low, application of compost and K slightly increased their concentration fractions. There was no carbonate while bicarbonate and chloride decreased. Sulphate, Ca and Mg, Na and K being increased by compost application. Bicarbonate, Ca and Mg decreased with cr, Na* and e being increased by r applications. Each of the mentioned applications generally increased field capacity, E C E, organic matter, total N contents, available N (NN4* + NO3), P, K, Fe, Mn and Zn with some exceptions . The trend of the subsurface 20-40 cm layer data was as the same as that of the upper 0-20 an layer but the available NO3*-N and P in that subsurface layer were lower than those of the upper one. Compost increased seed yield along with yield of seeds, pods, straw per plant as well as uptake of N, P, K, Fe, Mn and Zn at particularly 6 ton/fed. Potassium also caused increases in the indicated parameters as well as 100 seed weight by using either 25 or 50 kg K20/ fed, the significance being obtained by the higher rate. The interactions between compost and K were without significant effects rather than that attributed to the studied factors individually regardless combination in almost cases.
