ABSTRACT The present paper deals with the aerobiological investigation undertaken over Bajara (Pennisetum galaucum (L.) R.Br.) fields by using volumetric continuous Tilak Air sampler at. Shiral, Tal. Ashti, Dist. Beed (M.S.) India for two Kharif seasons during years 2013 and In the year 2013, eighty types of air borne components were trapped and identified while in the year 2014, eighty three types of air borne components were trapped and identified. All the trapped air borne components have been categorized under the groups like Zygomycotina, Ascomycotina, Basidiomycotina, Deuteromycotina, Myxomycotina of fungus group, Hypal fragments, Pollen grains, Protozoan cyst, Insect parts were included in Other types. In 1 st Kharif season of 2013 Cladosporium spore type is dominant and contributed 18.69%. It was followed by others: Curvularia (7.23 %), Alternaria (6.60 %), Hypal Fragments (5.52 %), Rust spores (5.50 %), Basidispores (3.86 %), Nigrospora (3.86 %), Periconia (3.52 %), Albugo (3.47 %), Psudotorulla (3.33 %), Aspergillus (1.32 %), Rhizopus (1.32 %), Cercospora (1.16 %), and Cunninghamella (0.81 %). In 2 nd Kharif season of 2014 also the Cladosporium spore type is dominant and contributed 19.11%. It was followed by Alternaria (7.36 %), Curvularia (6.68 %), Hypal fragments (5.96 %), Rust spores (5.16 %), Nigrospora (4.69 %), Periconia (4.34 %), Basidiospores (4.00 %), Pseudotorulla (3.32 %), Torulla (3.20 %), Rhizopus (1.49 %), Aspergillus (1.35 %), Cercospora (1.16 %) and Cunninghamella (0.73 %). KEYWARDS: Mycoflora, Airospora, Air Sampler, Air Borne Components, Disease forecasting. INTRODUCTION: Bajra (Pennisetum glaucum (L.) R. Br.) pearl millet is indigenous to Africa. It came into India in 1500 B.C. Bajra is one of the most common grains consumed widely in rural area in India and is referred as poor man s staple food. It is also used as good energy source because of rich in starch and amino acids. The Roti of Bajra promotes heart health as well as bleeding piles control. It also helps indigestion. Due to adaptation of this millet crop in dry and arid conditions it can grow in India where low fertility of soil, dry climates, high salinity, hot season and low ph predominate. The average rainfall suitable for this crop is cm annually. In the slight rain fall, the production of Bajra grain is better. The black or red upland soil and shady environment is favourable for Bajra crop. The temperature range 2531 O C is useful for better growth and high yield of the Bajra crop. The area under cultivation of Bajra across world is Sq. Kms, while in India million hectors land is under cultivation of Bajra crop. The average yield in India is 5.5 million of tonnes. Tamil Nadu is the highest producer of this crop. Other cultivator states of Bajra in India are Maharashtra, Uttar Pradesh, Gujarat, Haryana, Rajasthan etc. In the region of Beed district 1.95 hectors of land was brought under Bajra cultivation during the year Like many other crops the Bajra crop is also infected by various fungal diseases which may be soil, seed or airborne etc. The most important among them are rust pathogenic fungi of order puccinales (uredinales), Cercospora leaf spot, Bipolaris leaf spot, Curvularia leaf spot, downy mildew, ergot, exserolilum leafblight, head mold, Phyllosticta leaf blight, Pyricularia leaf spot. When the above fungal infection causes heavy damage to the crop it causes heavy loss to the cultivators. The references of the study 15 ISBN:
2 of aerobilogical mycoflora over Bajra crops are Kadam, Reddy and Biradar (2010, 2011) respectively, Mane (1978), Levetin, E. and Dorsey, K. (2006), Tiwari and Salauja (2007). With the help of this investigation we find the air borne fungal spores, their seasonal variation and their variation in the concentration. Such type of investigation is beneficial to farmers by timely warning of possibilities of epidemics by disease forecasting to the farmers. MATERIALS AND METHODS: Continuous Volumetric Tilak Air Samper was placed in the Bajra crop field at Shiral Ta. Ashti. Dist. Beed (M.S.) India for the 1 st Kharif season from 23 June 2013 to 6 October 2013 and 2 nd Kharif season started from 20 June 2014 to 10 October The sampler was kept at 1.5 meter height in the field of Bajra. The cellophane tape was slightly and thinly coated with adhesive white petroleum jelly on the drum of sampler. The tape faces the orfice of outward projecting tube 0.5 cm away from it. The drum rotates anticlockwise mechanism and completes one circle in 7 days. The air was sampled at the rate of 5 lit/min, which left traces of deposition over the cellophane tape on the drum. The slides were prepared after every seven days. Scanning was done under binocular electric microscope. The identification of spores was done which was based on the characteristics of spores such as, size, colour, shape and wall structure etc. The daily record of meteorological data was regularly maintained. RESULTS AND DISCUSSION: In the 1 st Kharif season class Deuteromycotina is dominant % of the total air spora followed by the Basidiomycotina %, other types 9.79 %, Ascomycotina 7.26 %, Zygomycotina 5.78 % and Myxomycotina 0.68 %. In the 2 nd season the class Deuteromycotina dominant % of the total airspora followed by the Basidiomycotina %, other types %, Ascomycotina 6.78 %, Zygomycotina 3.92 % and Myxomycotina 0.60 %. In the 1 st Kharif season 2013 class wise highest percentage of type of spore is as in class Zygomycotina Ablugo is 3.47 %, Ascomycotina Lacnadion is 1.45 %, rust spores 5.50%, Deuteromycotina Cladosporium 18.69%, Myxomycotina Stemonitis is 0.39 %, and in Other types Hypal fragments is 5.52 %. In the 2 nd Kharif season 2014 class wise highest percentage of type of spore in class Zygomycotina Ablugo and Rhizopus 1.49 %, Ascomycotina Lacnadion 1.15 %, Basidiomycotina Rust spores 5.16 %, Deuteromycotina Cladosporium 9.11 %, Myxomycotina Stemonitis 0.39 %, and in other types Hypal fragments is in 5.96 %. In the 1 st and 2 nd season of Bajra crop highest percentage of concentration of spore type is Cladosporium % and %, Curvularia 7.23 %and 6.68 %, Alternaria 6.60 % and 7.36 %, rust spores 5.50 % and 5.16 %, Nigrospora 3.86 % and 4.69 %, Basidiospores 3.86 % and 4.00 %, Periconia 3.33 % and 3.32 %, Pseudotorulla 3.33 % and 3.32 %, Torulla 2.40 % and 3.20 %, Albugo 3.47 % and 1.49 %, Rhizopus 1.32 % and 1.49 %, Aspergillus 1.32 % and 1.35 %, Cercospora 1.16 % and 1.06 % and Cunninghamella 0.81 % and 0.73% respectively. The aerobiological investigation of mycoflora has been already carried out by Cunningham, (1873); Gregory, (1961) Kulkarni, (1971) Tilak, and Mane (1981) Kshirsagar and Pande (2012). With the help of above references on investigation of mycoflora and my observations, the Bajra crop has affected by various fungal diseases like, rust, Cercospora leaf spot, Curvularia leaf spot, downy mildew, ergot, Exoserolium leaf blight, head mold etc. When the above diseases on the Bajra crop spread out of control, the crop gets affected heavily and it causes loss to the farmers. The above type of investigation is beneficial to farmers by timely warnings of possibilities of epidemics by disease forecasting to them ISBN:
