Permanent URI for this community

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.

    STUDIES ON SEED BORNE FUNGI IN GROUNDNUT
    (Acharya N G Ranga Agricultural University, Guntur, 2019) AISWARYA, NAYANI; SREE LAKSHMI, B
    The present investigation was carried out in the laboratory of Department of Seed Science and Technology, Advanced Post Graduate Centre, and RARS, Lam, Guntur, Andhra Pradesh during 2018-2019 to detect and isolate seed borne mycoflora of groundnut, to study the impact of Aspergillus spp. on seed quality parameters and management of Aspergillus spp. in groundnut. A total of 11 farmers’ saved seed samples of groundnut were collected from three different districts in Andhra Pradesh and 13 genotypes were collected from ARS, Kadiri and RARS, Tirupathi. The farmers’ saved seed samples were analysed for seed borne mycoflora by standard blotter method, deep freezing blotter method, 2, 4-D blotter method, agar plate method with PDA and paper towel method. A total of eight fungal species belonging to seven genera were found to be associated with the seed of groundnut. Among these fungi, the mean incidence of A. niger was highest followed by A. flavus, while that of Penicillium sp. was found to be the lowest in all the detection methods. Agar plate method was found to be efficient in isolation of A. niger, A. flavus, Rhizopus and Fusarium. 2, 4-D blotter method was found to be efficient for isolation of Macrophomina phaseolina and Alternaria. Standard blotter method was found to be better for isolation of Sclerotium. Deep freezing blotter method was found to be efficient for isolation of Penicillium. Of all the five methods tested, agar plate method with PDA was found to be superior in recording maximum incidence of mycoflora from all the test samples, while rolled paper towel method was found to be least effective for the detection of seed borne fungi. Samples collected from farmers of Guduru village of Nellore district were found to be highly infected with different mycoflora followed by samples collected from the farmers of Cherukupalli village of Guntur district while samples collected from the farmers of Yazili village of Guntur district were least infected with seed mycoflora. xv Studies on the location of seedborne fungi in the groundnut by component plating revealed that seed coat is the most infected part followed by cotyledons. A. niger remained the most frequently occurring fungus in both seed coat and cotyledons where as in case of embryo Fusarium followed M. phaseolina remained predominant. The impact of major seed borne fungi, A. niger and A. flavus on seed quality and biochemical characters of different genotypes was observed. Both these fungi caused reduction in all seed quality and biochemical characters except in per cent disease incidence and total phenol contents where an increasing trend is observed. Between these two fungi A. niger resulted in maximum changes in seed quality and biochemical characters over control. The results indicated that on an average, A. niger caused 25.14, 25.18, 43.99, 22.55 and 41.46 per cent reduction in seed germination, seedling length and seedling vigour index I, seedling dry weight and seedling vigour index II, respectively over control. Similarly A. flavus caused 22.38, 24.23, 41.18, 18.62 and 36.93 per cent reduction in seed germination, seedling length and seedling vigour index I, seedling dry weight and seedling vigour index II, respectively over control. The per cent infection increased from 8.87 in control to 42.23 and 40.94 in seeds inoculated with A. niger and A. flavus, respectively. On an average A. niger caused 8.82, 21.79 and 1.65 per cent decrease in protein, total sugar and oil contents and 13.22 per cent increase in total phenol content over control. Similarly A. flavus also caused 7.10, 12.08 and 1.33 per cent reduction in protein, total sugar, and oil contents and 11.69 per cent increase of phenol content over control. A total of eight treatments comprising of four fungicides viz., mancozeb, carbendazim, tebuconazole, carboxin+thiram and two bio-control agents viz., Trichoderma viride and Pseudomona fluorescens were evaluated against A. niger and A. flavus under in vitro conditions using rolled paper towel method. In case of A. niger inoculated seed, tebuconazole @ 1 g kg-1 seed recorded highest germination of 91.04% and lowest per cent disease incidence of 4.10 followed by carbendazim @ 2 g kg-1 seed. Highest seedling length (18.44 cm), seedling vigour index I (1660), seedling dry weight (0.22 g) and seedling vigour index II (19.48) was recorded in carbendazim @ 2 g kg-1 seed followed by carboxin+thiram @ 2 g kg-1 seed and mancozeb @ 3 g kg-1 seed. Similarly, in case of A. flavus inoculated seed, tebuconazole @ 1 g kg-1 seed recorded highest germination of 91.00% and lowest per cent disease incidence of 3.88 followed by carbendazim @ 2 g kg-1 seed. Highest seedling length (18.93 cm), seedling vigour index I (1716), seedling dry weight (0.23 g) and seedling vigour index II (20.60) was recorded in carbendazim @ 2 g kg-1 seed followed by carboxin+thiram @ 2 g kg-1 seed and mancozeb @ 3 g kg-1 seed. Based on the results obtained it is concluded that seed treatment with tebuconazole @ 1 g kg-1 or carbendazim @ 2 g kg-1 efficiently controls the seed borne infection of A. niger and A. flavus in groundnut.
