Abstract

Soils of Tripura are acidic, and having pH range from 4.5 to 6.5. Majority of soils are strongly acidic having a pH range of 5.1-5.5. Groundnut, a oilseed crop, can grow well on coarse-textured soils. These soils facilitate the better growth and development of groundnut pods. The low soil pH is associated with a number of soil chemical and biological properties that manifest themselves as the components of the acid soil syndrome. There are some specific problems which are associated with acid soils e.g., aluminum and manganese toxicity; molybdenum deficiency; failures in legume nodulation; increase in plant disease, and calcium and magnesium deficiency. These conditions may adversely affect groundnut growth. Liming is an important proposition to combat soil acidity, however, everywhere this approach does not prove economical and most of the time it is out of the reach of resource poor farmers. Thus, judicious application of lime and integrated nutrient management (combinations of bio-fertilizer, greeen manuring, organic manure and chemical fertilizer) can be practiced to formulate an integrated programme for acid soil management which will be eco-friendly and economic feasible tool to conquer productivity barrier and to attain sustainable groundnut production in acid soils of Tripura.
