Abstract:

Soil acidity is an important agricultural problem while evaluating the production potential of most of the crops. A field experiment was carried out at Alasulige village of Sakleshpur taluk, Hassan district, Karnataka to utilize the basic slag as a soil amendment and source of nutrients in acid soil in comparison with lime. Liming materials viz., basic slag and lime were tried along with farmer’s practice and RDF with RCBD design. The results of the experiment revealed that significantly higher grain (50.32 qha-1) and straw (65.93 qha-1) yield of paddy was recorded in treatment T9 (100% RDF + basic slag @ 2 tha-1) followed by T10 (100% RDF + lime @ 2 tha-1). Similarly, higher nutrient uptake was recorded in treatment T9 as compared to other treatments. Soil pH, available P2O5, exchangeable Ca and Mg contents of the soil were increased and the levels of DTPA extractable Fe and Mn in soil were decreased in treatments receiving basic slag and lime as compared to farmer’s practice. The study clearly indicated that in acidic soils, application of basic slag or lime @ 2 t ha-1 along with RDF is more beneficial in enhancing the crop yield as well as available nutrient status of soil.
