dc.description.abstractThe experiment conducted during 2015-16 at department of Agricultural Microbiology and Bioenergy, College of Agriculture, Rajendranagar, PJTSAU. Different carrier and liquid based biofertilizers are brought from different production units for evaluation of their quality. In case of carrier based biofertilizers, population of beneficial bacteria, pH, consistency, moisture content, level of contaminants were estimated. In case of liquid based biofertilizers, population of beneficial bacteria, pH, consistency and level of contaminants were estimated. The shelf life of biofertilzers were estimated using suitable media for viable count. Microbial population of beneficial bacteria was monitored in liquid and carrier based biofertilizers at monthly intervals. In liquid based biofertilizers viable count was constant for four months but a gradual decrease was observed in fifth and sixth months. Quality parameters of liquid based biofertilizers are good and constant for six months. In carrier based biofertilizers, the quality was too low, moisture content was high and count was decreased more. The field experiment was conducted following complete randomized design with control and 12 treatments. Treatments consisted of Control : 100% RDF, T 1 – T12 : 75% RDF +25% biofertilizer application, T 1 : CBF (seed treatment ) at the time of sowing, T2 : CBF (soil application) before sowing, T3 : CBF- liquid culture as soil application at the time of sowing, T4 : LBF - liquid culture (soil application) before sowing, T5 : LBF (seed treatment) at the time of sowing, T6 : LBF (soil application) before sowing, T7 : CBF (seed treatment at the time of sowing) + soil application at 40DAS, T8 : CBF (soil application before sowing) + soil application at 40 DAS, T9 : LBF (seed treatment at the time of sowing) + soil application at 40 DAS, T10 : LBF (soil application before sowing) + soil application at 40 DAS, T 11 : CBF-liquid culture(soil application at the time of sowing soil application at 40DAS), T 12 : LBF- liquid culture (Soil application before sowing) + soil application at 40 DAS.The growth parameters viz., plant height, root length, nodule number per plant, nodule dry weight (gm per plant), dry matter accumulation (gm per plant), were observed at different crop growth stages. Likewise observation on yield attributes viz., number of seeds per pod, test weight of seeds, seed yield were taken at harvest and nutrient uptake was estimated at harvest stage. Also available soil N, P and K were recorded at initial and at harvesting stage. Microbial population was recorded at initial, flowering and harvest stage. Application of carrier and liquid based biofertilizers in mungbean showed best result for the treatment T9 - Seed treatment with LBF at the time of sowing + soil application at 40 DAS. The treatment recorded maximum yield, number of seeds per pod and 100 seed weight than all other treatments. Treatment T10 - soil application with LBF at the time of sowing + soil application at 40 DAS was on par with T9. Highest nitrogen, phosphorous, potassium uptake, and higher available nitrogen, phosphorous, potassium in the soil were observed in the treatment T9 - LBF as seed treatment at the time of sowing + soil application at 40 DAS which was significantly higher than the biofertilizers applied through seedtreatment and soil application only once. At flowering and harvesting stage, treatment T9 - seed treatment with LBF at the time of sowing + soil application at 40 DAS recorded significantly higher bacterial, fungal, Rhizobium, Bacillus and actinomycetes population as compared to all other treatments. The significantly lowest bacterial, fungal, Rhizobium, Bacillus and actinomycetes population recorded with the treatment T3 - CBF Liquid culture as soil application at the time of sowing than all other treatments. .en_US
