Effect of urea and sludge based compost application on the yield of wheat (Triticum aestivum L.)

摘要

Wheat is accorded a premier place among the cereals because of the vast acreage devoted to its cultivation, its high nutritive value and its association with some of the earliest and most important civilizations of the world. India now ranks as the second largest wheat producer in the world. Out of the total world production of 595 m. tonnes, India produces about 66,5 m. tonnes with a productivity of 2700 kg/ha. Land application of sewage sludge provides an effective method of waste disposal which also recycles valuable nutrients into the soil-plant system (Maiti et al., 1992). Sewage sludge contains considerable amounts of major and minor plant nutrients and it has the potential as a substitute for commercial mineral fertiliser (Halderson and Zenz, 1978). With a view to find out the influence of the sludge based compost, the present investigation was conducted tO study the most suitable nitrogenous fertilisre for wheat crop during the rabi season.
