Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    IMPACT OF DIFFERENT RICE FARMING SYSTEMS ON DIVERSITY OF ARBUSCULAR MYCORRHIZAL (AM) FUNGI
    (Acharya N.G. Ranga Agricultural University, 2018) SAIKUMAR, PUDI; LAKSHMIPATHY, R
    Study on “Impact of different rice farming systems on diversity of arbuscular mycorrhizal (AM) fungi” was conducted at Agricultural research station, Amaravathi, Guntur during Kharif 2017-2018 by collecting the rhizosphere soil samples and root samples from selected agro climatic zones of Andhra Pradesh. The present study was undertaken to investigate the occurrence of AMF in different rice farming systems of selected agro climatic zones in Andhra Pradesh during different cropping stages of rice. A critical bench marks have been fixed in rice farming systems viz., intensive farming, natural farming and organic farming systems of North Coastal, Godavari, Krishna and Southern Zones to collect the rhizosphere soil samples and plant roots. These rhizosphere soil samples and plant roots were used for the enumeration of AMF spore density, per cent root colonization and spore types. The AMF spores density among different farming systems selected, it was more in soils collected from natural farming and least in case of intensive farming. The AMF spores density was highest in case of soil samples collected from paddy fields of Godavari zone and least in case of Southern Zone of Andhra Pradesh. The AMF per cent root colonization was more in case of root samples collected from paddy fields of Krishna Zone and least in case of Southern Zone. The AMF per cent root colonization among different rice farming systems selected, AMF percent root colonization was more in natural farming and least in case of intensive farming. Seventy one AMF spore types obtained from different rice farming systems of selected 4 agro climatic zones of Andhra Pradesh during 3 cropping stages rice were characterized based on spore morphology and they belong to 23 AMF species. Eleven AMF species from North Coastal Zone, 10 AMF species from Godavari Zone, 12 AMF species from Krishna Zone and 14 AMF species from Southern Zone were noticed. Regarding the frequency of distribution, Glomus fasciculatum was distributed more frequently in intensive farming system. While, in natural farming system Acaulospora morrowae was more frequently distributed. In organic farming system Acaulospora lacunosa was more frequently distributed. The genus Glomus was distributed more frequently than the genus Acaulospora. Shannon-Wiener diversity index of AM fungi was determined and it was more in organic farming system than other farming systems. Regarding agro climatic zones, AMF diversity was more in Krishna zone than other 3 zones. AMF diversity was more during grand growth stage compared to initial and harvesting stage. This study clearly showed a variation in physico-chemical and biochemical properties of soil, AMF activity and diversity of rhizosphere soils of different farming systems of selected agro climatic zones during 3 cropping stages of rice cultivation.
