Under acidic conditions, calcium and magnesium supply is reduced and plant growth suffers. In addition to these effects, other beneficial nutrients, such as nitrogen, phosphorus, and sulfur, are also in deficient concentration. The low yields of groundnut are due to poor pod filling in acid soils, owing to poor calcium-supplying power of soils. For meeting calcium demands and creating favorable conditions for better uptake of other essential nutrients, particularly phosphorus, liming is an important management practice in acid soils. The improvement of these acid soils should also aim at eliminating

the toxic effects of Al and Mn. The find more harmful effects of soil acidity can be eliminated by raising pH with suitable quantities of lime. Liming helps in raising the base saturation of the soil Belnacasan mouse and inactivating iron, aluminum, and manganese in the soil solution. Liming also helps to minimize phosphate fixation by iron and aluminum. Kamprath [8] reported the need for raising soil pH beyond the point of neutralizing

exchangeable aluminum, particularly for legumes. Recently, high-yielding cultivars of ricebean in northeastern states of India including Nagaland have been developed with extra short duration, bold seed, and dwarf plant types suitable for cultivation. These cultivars must be evaluated under different levels of lime in acid soils of the Nagaland foothills in the post-rainy season. The present investigation

was undertaken with the following objectives: (i) to evaluate the effect of lime on growth, yield attributes, yield, economics, and quality parameters, (ii) to evaluate the effect of lime on soil health, and (iii) to prescribe the best ricebean cultivars under foothill conditions during the post-rainy season. The field experiment was conducted during the post-rainy seasons of 2010–2011 and 2011–2012 at the Agricultural Pyruvate dehydrogenase Research Farm of ICAR, RC for NEH Region, Nagaland Centre, Jharnapani, Nagaland, India. The experimental site was located at 25.45° N latitude 93.53° E longitude with a mean altitude of 295 m ASL. The climate of the experimental site was subtropical with high humidity and medium to high rainfall. The soil was sandy loam and acidic in reaction (pH 4.9). The soil contained 0.95% oxidizable organic carbon, 235 kg ha− 1 mineralizable nitrogen, 136 kg ha− 1 available potassium, and 10.3 kg ha− 1 available phosphorus. During the experimental period the maximum and minimum temperatures varied from 23.0 °C to 31.1 °C and 9.7 °C to 24.0 °C, respectively, during 2010–2011 and 24.3 °C to 31.2 °C and 9.5 °C to 24.2 °C during 2011–2012. The maximum and minimum relative humidities ranged from 75% to 84% and 38% to 67%, respectively, during 2010–2011 and 78% to 85% and 78% to 63% during 2011–2012. Total precipitations of 225.2 mm and 315.
