dc.descriptionThis investigation was carried out to study the “Effect of Biofertilizers and Plant Growth Stimulator on Seed Germination and Early Development in Citrus cv. Rangpur Limeunder Hydroponic Condition during the year 2019-2020. The experiment was laid out in Complete Randomized Design (CRD) comprising of three (3) replications and eight (8) treatments. All biofertilizers and growth stimulator gave promising results compared to control. Minimum fungal incidence was observed in Trichoderma viride (T4) and Pseudomonas fluorescens (T1) in which fungal incidence was (0.08%), maximum seed germination percentage was recorded in the treatments of mycorrhiza (T2) and Trichodermaviride combined with Humicil (T7) that was recorded (86.67%), maximum plant height (15.67 cm), seedling girth (1.43 mm), tap root length (22.00 cm) and number of lateral roots (29.67/plant) wassignificantly recordedin the treatment ofTrichoderma viridethat was applied alone(T4).Highest number of leaves per plant was recorded in (Trichoderma viride + Humicil) (T7) (6.33). The highest chlorophyll content among the treatments was recorded in the treatment of mycorrhiza (T2) as the Chlorophyll a (1.73mg/g), Chlorophyll b (1.10mg/g) and total chlorophyll (2.83 mg/g). The highest (98.67%) survival percentage of seedlings was recorded in the treatment of alone applicationof Humicil (T3). Significant improvement of macronutrients was recorded as following; highest nitrogenwas recorded in Pseudomonas fluorescens (T1) (2.321%), phosphorus was recorded in the treatment of Mycorrhiza combined with Humicil (T6) (0.183%),potassium was recorded inTrichoderma viride (3.185%) followed significantly by mycorrhiza (T2) with respect to (NPK) as (1.999%), (0.165%) and (3.170%). The lowest data among the treatments was taken from control as in the following parameters, fungal infection (14.44%), seed germination (72.20%), plant height(13.00 cm), number of leaves (4.10), seedling girth (1.10mm), tap root length (14.67cm), number of lateral roots(17.33), chlorophyll a (0.84mg/g), chlorophyll b (0.68 mg/g), total chlorophyll content (1.50mg/g), survival of seedlings (70.77%)respectively.en_US
