Academic Editor / Reviewer: Dr Levent Arin, Dr Wajid Hasan, Dr Sunita Kushwaha, Dr Dharmendra K R Introduction Carrot (Daucus carota L.) is one of the most important root vegetables of both tropical and temperate countries. It belongs to family Umbelliferae with chromosome no. 2n=18. The primary center of origin of carrot ranges from Afghanistan to Mediterranean region and South –west Asia is the secondary center of origin. Carrot is used as salad, cooked as vegetables preferably with potatoes and peas. Presently, 210 g per capita consumption of vegetables is much less than the dietary requirement Rai and Pandey [1]. Carrot juice is becoming popular day by day. A special type of beverage known as kanji is prepared from black carrot and used as appetizer. It is used in making pickles and sweets. Orange coloured roots of carrot contain more carotenes than red colored type and rich in thiamine and riboflavin, while Asiatic type contains more anthocyanin pigment and poor in nutritive value. Secondary nutrients such as calcium and sulphur used for better growth, fruit yield and seed yield. The cost of chemical fertilizer has been enormously increasing to an extent that they are out of reach of the small farmers. Organic farming avoids or largely excludes the use of synthetically produced fertilizer, pesticides, growth regulators and livestock feed additives to the maximum extent possible, Organic farming rely upon crop rotation, crop residues, animal manures, legumes, green manures, off farming organic waste, mineral bearing rocks and bio-fertilizers to maintain soil health, tilt and to supply plant nutrients and biological means to control insects, weeds and diseases. It is a well documented that increased dependence on agrochemicals including fertilizer has led to several ill effects on the human health. So, one should aware for eco-friendly organic products. It also improves growth, yield as well as quality of crop. The use of bio-fertilizer in such situation is therefore a practically paying proposal. The gravity of ecological degradation is prime attention of the researchers to find out an ecologically sound, viable and sustainable farming system safe for future generation [2, 3]. Keeping these points the present experiment was conducted with judicial application of inorganic, organic and bio-fertilizers in an integrated way. Materialsand Methods The investigation was carried out at Horticulture Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow during 2013-14. The layout of experimental field was laid down in Randomized Block Design with twelve treatments and three replications. The treatment combinations were control, recommended dose of fertilizers (RDF), 100% Azotobacter, 100% Azospirillum, 100% PSB, 50% RDF + 50% Azotobacter, 50% RDF + 50% Azospirillum, 50% RDF + 50% PSB, 50% Azotobacter + 50% Azospirillum, 50% Azotobacter + 50% PSB, 50% PSB + 50% Azospirillum and 25% RDF+25% FYM +25% vermin-compost +25% PSB. During the land preparation the whole quantities of FYM @ 10 tonnes and Vermi-compost @ 4 tonnes per hectare were incorporated in the soil. The sources of fertilizers are Urea, DAP and MOP. In carrot the recommended dose of NPK is 120: 60:60 Kg/ha. Jaggery solution was prepared by dissolving 25g of Jaggery in 250 ml water and 50g PSB were added to this solution. Solution was spread on the seed and mixed thoroughly with hand to obtain uniform coating. Treated seeds were kept in shade for drying. Seeds were sown in the evening on ridge after treating the seed with bio-fertilizers and after that light irrigation was given to each plot to facilitate the germination of seed. Seeds were germinated 10-15 days after sowing. The observed data were statically analyzed and treatment effects were compared at 5% level of significance Panse and Sukhatme [4]. Results and discussion The experimental findings presented in [Table-1] provided a detailed account of International Journal of Agriculture Sciences ISSN: 0975-3710&E-ISSN: 0975-9107, Volume 8, Issue 51, 2017, pp.2187-2188.

Pusa Rudhira” was conducted at Horticulture Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow during year of 2013- 14. The experiment was laid out in Randomized Block Design with twelve treatments and three replications. The treatment combinations were control, recommended dose of fertilizers (RDF), 100% Azotobacter, 100% Azospirillum, 100% PSB, 50% RDF + 50% Azotobacter, 50% RDF + 50% Azospirillum, 50% RDF + 50% PSB, 50% Azotobacter + 50% Azospirillum, 50% Azotobacter + 50% PSB, 50% PSB + 50% Azospirillum and 25% RDF+25% FYM +25% vermin-compost +25% PSB. The observations were recorded on vegetative characters, yield and physico-chemical quality of roots. From the analysis of data, it can be concluded that the application of 25% PSB + 25% Azospirillum + 25% RDF+ 25% Azotobacter (T12) increased the growth, yield and nutritional quality of carrot grown under subtropical condition.
