Transcript

  • Biofertilizers Use in Tomato

  • Introduction Increase yield by 20-30% in crops Biofertilizers Use in TomatoBiofertilizers are ready to use live formulations of beneficial microorganisms which on application, mobilize availability of nutrients by their biological activity and build up soil healthForm a part of integrated nutrient managementIdeal for farmers practicing organic farming

  • Types of biofertilizers

    Biofertilizers Use in Tomato

  • Biofertilizers fix atmospheric nitrogen in the soil and make it available to the plants

    Decompose organic matter and help in mineralisation

    Produce hormones that promote root growth

    Mode of action of biofertilizers

    Biofertilizers Use in Tomato

  • Cost effective: increase crop yield by 10-30%

    Activate the soil biologically

    Restore natural soil fertility

    Supplement to fertilizers: replace chemical fertilizers upto 25%

    Provide protection against some soil borne diseases

    Benefits of biofertilizers

    Biofertilizers Use in Tomato

  • Azotobacter with phosphate solubilizing bacteria is recommended for tomato crop

    Azotobacter acts by

    Supplying 20-40 mg N/g of carbon source Producing growth substances like vitamins, IAA and Gibberellic acidBiological control of plant diseases and suppresses plant pathogens

    Mycorrhiza help by solubilizing nutrients and overcoming moisture stress

    Biofertilizer for tomato

    Biofertilizers Use in Tomato

  • Seed Treatment

    Suspend one packet (200 g) of biofertilizer in approx. 400 ml water (1:2) to treat 10-12 kg tomato seed

    Pour the suspension over the seeds Mix thoroughly to apply uniformly

    Dry the seeds in shade and sow

    Sugar solution (10%) or gum arabica (10%) can be used as an adhesiveMethod of applicationContd..Biofertilizers Use in Tomato

  • Seedling dipping Suspend 1kg (5 packets) biofertilizer culture in 10-15 litres of water. One packet is sufficient for 0.1 ha area

    Make small bundles of tomato seedlings

    Dip the root of the seedlings in the suspension for 15-30 minutes

    Transplant immediatelyMethod of applicationContd..Biofertilizers Use in Tomato

  • Soil application

    Mix 10-15 packets (each of 200 g) with 40-60 kg of well decomposed cattle manure or with 40-60 kg soil for one acre area Wet the mixture by sprinkling water Broadcast into the soil at the time of sowingMethod of applicationBiofertilizers Use in Tomato

  • Precautions for using BiofertilizersBiofertilizer packets should be stored in cool and dry place away from direct sunlight

    Do not mix biofertilizer simultaneously with inorganic fertilizers/pesticides

    Biofertilizer packet should be used before its expiry

    For better results, biofertilizers should be used in combination with inorganic fertilizers Biofertilizers Use in Tomato

  • Biofertilizers are useful microorganisms that provide nutrients to the plants in the rhizosphere

    Reduce environmental pollution and cut down the cost of chemical fertilizers

    Release the nutrients gradually and prevent leaching of nutrients from the soil

    Improve soil health and provide protection against some soil borne diseases

    Biofertilizers are applied to the crop as seed, seedling or soil treatmentLet us sum upBiofertilizers Use in Tomato
