Abstract
A Study on the soil acidity and lime requirement in jhum fields under rice cultivation was undertaken during 2016-17 in the Department of Agricultural Chemistry and Soil Science, School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema Nagaland. Altogether 30 surface soil samples in rice jhum fields from 15 villages under Sitimi block of Kiphire district were collected for the study. The pH the soils of different villages under Kiphire district ranged from 5.03- 6.08. The values of OC ranged from 0.96-5.86. Available N, P and K ranged from 150.53-602.11 kg ha-1, 4.10-28.21 kg ha-1 and 121.50-218.27 kg ha-1 respectively. The total acidity, exchange acidity and pH dependent acidity varied from 0.53-3.01 c mol (p+) kg-1, 0.13-2.00 c mol (p+) kg-1 and 3.60-14.43 c mol (p+) kg-1 respectively. Lime requirement for jhum ranged from 4.5-16.3 & 5.5-19.3 t ha-1 to raise the soil pH to 6.0 & 6.4 respectively.
