Abstract:

A lysimetric study was conducted during 1995-97 in Haryana, India to assess the effect of fly ash application on the performance of wheat on sandy, sandy loam, and loam soils. The treatments were 0.0, 2.5, 5.0, and 10.0% fly ash (w/w) mixed in the top 15-cm layer and 2.5-cm fly ash on the surface of each soil type. The highest grain and straw yields were obtained with the application of 2.5-cm fly ash, irrespective of the soil type. In addition, soil type significantly influenced the grain and straw yields, where the highest were obtained in loam soil. A maximum reduction in evaporation was observed under 2.5-cm fly ash layer (13.3%) treatment and in loam soils. Wheat, on an average, consumed 346-, 330-, and 316-mm water as evapotranspiration to complete its life cycle, respectively, in loam, sandy loam, and sandy soils. Fly ash at 2.5 cm gave the highest water use efficiency compared to the control. The mean water use efficiency improved by 9.9, 20.5, and 27.2 in loam; 7.0, 12.6, and 22.5 in sandy loam; and 7.7, 18.9, and 26.5 in sandy loam soil with incorporation of 2.5, 5.0, and 10.0% fly ash, respectively. Root density improved with an increase in the application rate of fly ash and was highest with 2.5 cm fly ash layer in all soil types.
