The present investigation was carried out to study the soils macro and micro nutrient status of tamarind orchards in Latur district during the year 2017-2018. The framed experiment was concentrated, to assess and find out the soil nutrient status of tamarind orchards, relation between soil nutrients and yield of sole and bund crops and unfruitfulness of sole crops in tamarind orchards in Marathwada region. Twenty tamarind orchards of eight to thirty five years age planted at different spacing ranging from 8 x 8 m to 10 x 10 m with plant density of 100 to 150 plant ha-1 under varied management practices located in different tehsil’s of Latur district were selected for the experimentation. In Marathwada region, in sole planting, soil macro-nutrients ranged from N (129.28 to 250.00 kg ha-1), P (11.00 to 38.00 kg ha-1), K (172.00 to 998.00 kg ha-1), Ca (19.00 to 55.23 cmol( p+) kg-1), Mg (186.00 to 397.00 (p+) kg-1) and S (11.25 to 18.00 (p+) kg-1) and soil micro-nutrients ranged from Fe (1.20 to 3.92 mg kg-1), Mn (3.51 to 19.78 mg kg-1), Cu (1.30 to 8.60 mg kg-1), B (0.17 to 1.40 mg kg-1) and Zn (0.21 to 2.79 mg kg-1) were observed. However, in bund planting, soil macro-nutrients ranged from N (137.25 to 258.01kgha-1), P (11.01 to 37.25kgha-1), K (178.11 to 998.80 kgha-1), Ca(19.20 to 55.80cmol(p+) kg-1), Mg(197.80 to 395cmol(p+) kg-1) and S(11.50 to 18.40 cmol(p+) kg-1) and soil micro-nutrients ranged from Fe (1.05 to 3.91mg kg-1), Mn (3.34 to 18.28mg kg-1), Zn (0.21 to 2.95mg kg-1), Cu (1.05 to 7.95mg kg-1) and B(0.5 to 1.90mg kg-1) were observed. The results showed that, these soil macro and micro nutrients ranges are also beneficial to the fruitfulness of tamarinds. Hence, it can be concluded that, there is no effect of soil macro and micro nutrients in unfruitfulness of sole orchard and fruitfulness of bund orchard in tamarind. It might be effect of shading in sole crops for unfruitfulness and in case of bund crop orchards it could get proper aeration and sunlight properly.
