Effect of Some Organic Fertilizers in Soil Fertility Characteristics and its Productivity of Chard


Abstract in English

A field experiment was carried out to investigate the effects of organic fertilizers (mushroom substrate residues, poultry manure and city compost) and mineral fertilizers (NPK) on some properties and productivity of a calcareous soil using chard (Beta vulgaris) as a test crop. The plant was cultivated at spring season 2009. The first cut was after 60 days of swing. The results of experiment were: The NPK fertilizer significantly affected dry weight of plant yield (157.6g/m2soil) and the efficiency of fertilizer in productivity was 50.8% compare to control (104.5g/m2soil). The treatment of 50% NPK + 50% poultry manure gave the highest yeld compare to other treatments. However the organic treatments did not differ significantly among them. Concentrations of NPK nutrients in plant leaves were as follows: NPK > 50% NPK + 50% poultry manure > poultry manure > 50% NPK + 50% mushroom substrate > mushroom substrate > 50% NPK + 50% city compost > city compost. The organic fertilizers decreased the NPK in plant and soil compare with NPK fertilizer treatment. However there was no significant differences between NPK treatment yield and 50% NPK + 50 % poultry manure treatment. It was concluded that the use of 50% NPK +50 % orgnic fertilizer (specially poultry manure) was important to get best result.
