Effect of Different Liquid Biofertilizers and Varying Fertility Levels on Available N, P2O5, K2O and S Content after Harvesting in Soil

The experimental trail was conducted at the farm of Rajasthan Agricultural Research Institute (RARI), Durgapura, Jaipur which is the sub campus of Sri Karan Narendra Agriculture University, Jobner, Jaipur (Raj.). In the research study, observed the effect of different liquid biofertilizers and fertility levels on growth, yield and quality of cluster bean (cymopsis tetragonoloba). The test crops were grown on field during July to November kharif-2018 and 2019. The experiment was raised in factorial randomized block design (FRBD). The treatments of experiment comprised of two factors (1) three treatment of fertility levels: 100 % recommended dose of fertilizers (F1), 75% RDF (F2) and 50 % RDF (F3) and eight treatment of liquid biofertilizer : Control-no biofertilizers (L0), Rhizobium (L1), PSB-phosphorus solubilizing bacteria (L2), KMB-potassium solubilizing bacteria (L 3), SSB-sulphur solubilizing bacteria (L 4) , Rhizobium + PSB (L 5 ), Rhizobium + PSB+ KMB (L 6 ) and Rhizobium + PSB+ KMB + SSB (L 7). Total number of treatments were 24 and replicated three times. The result observed that highest nutrient status found in the combination of 100 % RDF (F1) with Rhizobium + PSB+ KMB + SSB (L 7).
