In: Minufiya journal of agricultural research 2008.v.33(3)Summary: Filed experiment was carried out In 2005 at EI Nubaria Agricultural research station in EI Behera Governorate, to study the effect of banana compost and their combination with mineral fertilizers on sandy calcareous soil content of Ni, Cd and Pb as wefl as its hydro-physical properties and reducing pollution of corn plants. In the same plOts, bean was planted to evaluate the residual effect of treatments. The experiment included three main plots [60% (I,), 80%(1:J and 100% (I,) of full water requIrement] and six fertilization treatments [150% compost (F,), 100% compost (F:J, 75% compost + 25% NPK (F,j, 50% compost + 50% NPK (F.,j, full recommended NPK (FsJ and control (FrJ]. Results indicated that, about 20% of irrigation water can be saved if farmers applied 80% of full water requirement to corn plants. Also, corn grain yield increased with increasing mineral fertilizer rate in contrast of bean yield which increase, with raising compost level. Under low amount of water, application of (75% compost + 25% NPK) Increased water use efficiency (WUE) of corn yield than (50% compost + 50% NPK). Cadmium and nickel concentrations in green leaves, ear leaf, corn grains and bean seeds increased with decreasing water doses. No clear relationship was observed between Pb concentration In responsive plant parts and irrigation treatments. In general, replacing compost instead of mineral fertilizers reduce concentration of Ni, Cd and Pb in com and bean tissues. All plots treated with lower water dose produced higher available heavy metals. There are positive Increase in extractable Cd, Ni and Pb due to application of minerai fertilizers in comparison with those obtained when compost was added. Application of compost decreased soli bulk density (BD) and Increased total porosity, water holding pores, total soil aggregates and aggregation index, subsequently Increased field capacity and available water.
