Effect of different biofertilizer strains on soil, leaf and yield parameters of Kinnow mandarin

Present field study was carried out to investigate the effects of biofertilizer strains on soil, leaf and yield parameters Kinnow zandarin (C. nobilis × C. deliciosa) during 2018–19 2019–20 at experimental orchard Department Horticulture, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana. The revealed that nutrient status were significantly affected with application biofertilizers. There synergistic influence Azotobacter PSB strains. magnitude increase different bio-strains more pronounced when applied in combination lower dose fertilizers (75% RDF) than their higher (100% RDF). 100% RDF + chroococcum Mac 27 Pseudomonas P 36 (T7) found most effective enhancing soil macro-micro nutrients, parameters.Soil available N increased 0–15 cm layer both years but 15–30 layer, enhancement observed only second year investigation, however Fe, Zn Mn showed significant improvement years. Leaf content September, no effect March values. fast increment as compared content.
