Abstract:

The influence of organic matter vis-a-vis humic acids on the availability of nutrient status and its impact on the cultivation of rice (Variety MTU 1010) followed by mustard (Variety B-9), was studied in Typic Fluvaquent soil under Old Alluvial zone of West Bengal, India. Soil texture was identified as sandy clay loam, bulk density 1.34 Mg m-3, oxidizable OC 1.16 g 100gm-1, pH 6.34, total nitrogen 0.14 g 100gm-1, available phosphate, potash and sulphate 25.90, 127.40, 39.56 kg ha-1, respectively. Soils received recommended doses of fertilizers for cultivation of paddy (N:P2O5:K2O::60:30:30) followed by mustard (N:P2O5:K2O::80:40:40) along with FYM at 5.0 and 2.5 t ha-1, both Commercial and FYM extracted humic acid (CHA & EHA) at 0.5, 0.25 kg ha-1, respectively as per treatment combinations and following RBD treatment. Rhizosphere soil (0-15 cm) and plant samples were periodically collected and analysed for C:N ratio, available phosphate, potash and sulphur with their integral effect on crop growth. At PI and branching stages of paddy and mustard, the highest content of available phosphate, potash and sulphur was recorded and gradually decreasd towards harvesting stage. EHA resulted highest availability of phosphate and sulphur, however CHA enhanced the content of potash in soil, resulted significant uptake of nutrients within plants and qualitative enrichment through biometric parameters and yield.
