Field investigations are important tools for confirmation of the effectiveness of the organic manures on crop yield. As different N sources, this work presents a comparative study of the effects of urea, cow dung and poultry manure on plant height, stem length and diameter, leaf length, breadth and number accompanied with the fresh weight of plant, stem, leaf coupling stem leaf ratio and gross ...
Compost and sewage sludge contain high concentration of plant nutrients and, thus, have been used extensively as an inexpensive fertilizer. The objective of this study was to evaluate cumulative and residual effects of compost, sewage sludge and cow manure on nitrogen, phosphorus and potassium in soil and wheat. The experiment included compost, sewage sludge and cow manure, each applied at 3 ra...

Organic matter (OM) and total N (N) are relatively low in majority of the calcareous soils in Iran, and continuous use of N fertilizer would impair the quality of surface and ground water and creates other environmental hazards. Therefore, the combined use of N fertilizer and organic wastes is important to partly supply plant N requirement, improve physico-chemical properties of soil and conser...
