“Any living organism supplying plant nutrients directly or indirectly is regarded as biofertilizer. They are not synthetically manufactured in factory.”
Bt cotton is a genetically modified variety of cotton that expresses a gene from the soil bacterium Bacillus thuringiensis (Bt), which produces a protein that is toxic to certain insect pests like bollworms but harmless to other organisms. It was developed to control major cotton pests that can cause significant yield losses. Bt cotton reduces the need for insecticide use and promotes more environmentally friendly cotton cultivation while protecting yields. The Bt gene works by being toxic only to insects that ingest the Bt protein, but is safe for other animals and humans.

Nicoorgo Manure’sbio-control agentsare :
Nicoderma:Trichoderma Viride
Bioniconema:Paecilomyceslilacinus (Pseudomonasfluroscense)
Nicodermaisa biological fungicide &Bioniconemaisabiological nematicide. Toprotectseedislike polio
vaccinationtoprotectchildrenagainstpoliodisease. Disease&Nematode isthe mainfactorthat reduce
crop yieldamongthe variousfactor.Mainlyseedborne &soil borne disease have seenincrop.Still
farmerhas no awarenessregardingdisease&nematode infection.Once cropisinfectedwithdisease &
nematode ,farmerhas notcontrol overit & ultimatelytheyhave gotmuchlossinyield,quality&
Quantity.Forthat seedtreatmentisnecessaryinadvance tocontrol disease &nematode.Farmersare
givenonlychemicallyseedtreatmentwhichisonlybasicbutbiologicallyseedtreatmentismost

2. Bio All
(Nutrient mobilizing liquid bio fertilizer)
BioAll has the unique abilitytoenrichthe soil withNitrogen,Phosphorousandpotash.It
efficientlyfixesatmosphericnitrogen,solubilizes insolubleandchemicallyfixedphosphatesand
has the abilitytomobilizeandsolubilize soilpotashandinsoluble potashcompoundsthus
makingall three of these essential nutrientsavailable tothe plantina ready,available form.
It alsoenhancesthe availabilityof Mn,Mg, Fe,Mo, Bo, Zn,and Cu, amongothers,inthe soil.
BioAll providesthe majornutrients(NPK) tothe soil whichresultsinhigheryield.BioAll
producescertaingrowthpromotingsubstancessuchasThiamine ,Indol andaceticacid which
helpimpartresistance tothe plantfromplantpathogenssuchas Alternariaandfusarium.It
Producesorganicacidslike citric, tartaric , Malicwhichincrease the availabilityof phosphatesin
the rhizosphere.
For Seedtreatment: 5ml to 7ml of Bio All per kg of seeds.
RecommendedCrops:Substantiallyenhancesgrowthincereals,pulses,vegetables,cotton,
oilseeds,fruitcrops,paddy, wheat, sugarcane , banana , Mustard seed,sunflower,soybean,
Onion, Garlic, Coffee ,Termeric, Mango , grapes ,Cardamon , Potatoes&Ornamental plants.
3. Bio Micro
(Micronutrient mobilizing liquid bio fertilizer) :
BioMicro, a biological mix, is capable of mobilizing Iron, Zinc and Sulphur and making them
available to the plant. This combination of selected and compatible bacteria acts to give
essential micronutrients to the plant. Iron mobilizing bacteria efficiently make iron available to
the plant. The metabolites secreted by microorganisms into the soil as strong chemical reagents
and the activities of microbial enzymes are principal factors in this process. Sulphur Mobilizing
bacteria - mobilize insoluble and chemically fixed sulphates and make them available to the
plant Zinc mobilizing bacteria - play an important role in increasing the availability of Zn in soil,
thus enhancing Zn accumulation. It fortifies the soil with bacterial metabolites . BioMicro
produces many organic acids like Ferric acid, Nicotinic acid, Tartaric acid, Mallic acid etc.
resulting in an overall increase in the availability of important micronutrients in the
rhizosphere.
For Seed treatment: 5ml of Bio Micro per kg of seeds.
RecommendedCrops:Substantiallyenhancesgrowthincereals,pulses,vegetables, cotton , oilseeds ,
fruit crops , paddy , wheat , sugarcane , banana , mustard seed , sunflower , Soybean , Onion , Garlic ,
Termeric , Mango , Grapes , Cardamon , Potatoes & Ornamental Plants.
4. P-Sol
(Phosphate solubilizing Bacteria)
Large amounts of phosphate fertilizers are used on a regular basis, but a large portion of
applied phosphorus is quickly converted to the insoluble form and only about 20-25% of
applied phosphorus is useful. A greater part of soil phosphorus is present in an insoluble form
and hence is unavailable to the plant. Phosphate solubilizing microorganisms are capable of
solubilizing Ca, Al, Fe phosphates as well as rock phosphates and mineralizing organic
phosphorus, making the phosphorus present in the soil available to the crop. [↑ 15%]
Seedtreatment: 5ml to 7ml of PSB per kg seeds.
5. N-Fix
(Nitrogen fixing soil enhancer)
N-fix hasthe abilitytofix atmosphericnitrogenforthe plant.Ithasan associative symbiotic
relationwithgraminaceousplants,therebymakingavailable atmosphericnitrogen(30-50%of N
requirement) tovariouscrops.Itsecretsammoniainthe rhizosphere inthe presence of root
exudates,whichhelpsnutrientuptake byplants.N-fix hasthe abilitytosynthesize auxins,
cytokinines,vitaminsandgrowthpromotingsubstancessuchasThiamin,riboflavin,Indole
aceticacid , gibberellins,nicotinicacidandvitaminB.Itsnitrogenfixingactivitycontinueseven
afterthe existingsourcesof nitrogenhave beenexhausted.Presence of organicmatter,
cellulolyticmicroorganismsandsmall amountsof humanscanfurtherincrease the efficiencyof
N-fix.
For Seedtreatment: 5-7ml per kg of seeds.
6. Nicoderma
(Bio fungicide)
Trichodermaviride isanantagonisticfungal organismpresentinthe soil andishighlyeffective forthe
control of seedandsoil borne diseasesof amajorityof economicallyimportantcrops,especiallypulses
and oil seeds.Thisbiocontrol agentwhenappliedalongwithseed,colonizesthe seedandmultiplieson

SeedtreatmentwithTrichodermaviride hasregisteredhighergerminationinanumberof studiesand
was at par with“Captan”.It is effective forcontrol of soil borne diseasescausedbyRhizoctoniasolani,
MacrophominaphaseolinaandFusariumspp;andisa veryimportantweaponagainstdiseasessuchas
root rot, seedlingdiseases,charcoal rot,wilt,damping- off,collarrot,etc.The potential of Trichoderma
viride inmanagingsoil borne pathogenshasbeendemonstratedinmanycropdiseaseslike seedling
disease of cotton(RamakrishnaandJeyarajan,1986; Aagarsamyet al.,1987a and b) root rot of
soyabean(JhariaandKhare-1986),root rot of Cowpea(Alagarasami Shivaprakasam.1988),charcoal rot
of sorghum(SekharandAnalosur,1986) and root rot of mung beancausedbyMacrophomina
phaseolina(Samiyyapanet.al,1987).
Seedtreatment: 10gm/kg seeds.
Caution:
ApplyNicoderma/Bioniconema/BioAll/keeping7-8daysgap of chemical fertilizer
applicationinthe soil.
7. Bioniconema
(Bio-nematicides)
Paecilomyces lilacinus has been one of the principal genera of importance in bio-control studies
in recent years. Paecilomyces lilacinus, a bio-control fungus, protects the root systemagainst
diseases caused by plant parasitic nematodes, specifically root-knot nematodes (Meloidogyne
spp.), reniform nematodes (Rotylenchulus reniformis), burrowing nematodes (Radopholus
similes) and citrus nematodes (Tylenchulus semipenetrans). These nematodes infect agricultural
and horticultural crops of economic importance. This bio-agent colonizes the root surface and is
an antagonistic fungus, strongly parasitic to eggs and egg-masses of plant parastic nematodes.
Bioniconema can destroy upto 90% of eggs and 75%-80% of eggmasses of nematodes.
Seedtreatment: 10gm/kg seeds
8. Effect of organic inputs of Nico Orgo on Potato crop
Increases speed of germination of potato tuber.
Increases potato tuber size.
Increases luster of potato tubers.
Increases potato tuber yield and quality.
Increases storage capacity of potato tubers.
Steps to increase potato tuber Yield:
• Prefer sandy , goradu , and medium black soil for better yield of potato tubers.
• Use 600 kg seeds for sowing one vigha.
• Make only two pieces of one tuber and each piece should weigh minimum 50 g weight.
• Treat seeds with Nicoderma @ 10 g/kg seeds or mix 1 kg nicoderma in 150-200 kg orgo
manure / vigha and apply or apply 100-150 kg jaivik / vigha under the crop row for control
of black scurf disease of potato.
• Treat seeds with Bioniconema @ 10 g/kg seeds or mix 1 kg bioniconema in 150-200 kg
orgo manure/vigha and apply or apply 100-150 kg samrat/vigha under the crop row.
• Sow seeds(tuberpieces) at 50cm (betweenthe row) and 15cm (within the row between
pieces).
• Sow/plant tuber seeds around 15-30 november depending upon the temperature
prevailing.
