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.

    SEASONAL INCIDENCE AND MANAGEMENT OF Helicoverpa armigera (HUBNER) AND Maruca vitrata (GEYER) IN PIGEONPEA (Cajanus cajan L.)
    (ACHARYA N G RANGA AGRICULTURAL UNIVERSITY, GUNTUR, 2019) DIVYASREE, CHINTA; SREEKANTH, M
    A field experiment entitled “SEASONAL INCIDENCE AND MANAGEMENT OF Helicoverpa armigera (HUBNER) AND Maruca vitrata (GEYER) IN PIGEONPEA (Cajanus cajan L.)” was conducted at Regional Agricultural Research Station (RARS), Lam, Guntur during kharif, 2018 with an aim to know the Resistant/tolerant pigeonpea genotypes, occurrence and eco-friendly management of H. armigera and M. vitrata. Among the genotypes screened, RKPV 527-01, GJP 1606, JKM 189, BDN 711, ICPL 87119, RVSA 16-4, IPA 15-05 and LRG 467 were found resistant to both H.armigera and M.vitrata. The peak moth (6.8 moths/trap/week) and larval (4.00 larvae/plant) population of H.armigera was observed during last week of October (43rd SMW) and second week of November (45th SMW), respectively. The peak moth (7.2 moths/trap/week) and larval (4.6 larvae/plant) population M.vitrata was observed during third week of November (46th SMW). Adult and larval population of H.armigera and M.vitrata were found significantly correlated with maximum temperature and evaporation. All the weather variables together contributed to the incidence of H.armigera adult and larval population by 62.00 (R2= 0.62) and 74.00 (R2= 0.74) per cent, respectively. Similarly, all the weather variables together contributed to the incidence of M.vitrata adult and larval population by 73.00 (R2= 0.73 and 70.00 (R2= 0.70) per cent, respectively. Among different eco-friendly products evaluated against H.armigera and M.vitrata, spinosad 45 % SC @ 73 g a.i/ha, followed by NSKE @ 5 % were found effective with less no. of larvae and there by less pod and seed damage. Thus, spinosad 45 % SC @ 73 g a.i/ha has recorded 92.36 and 92.84 % reduction of larval populations of H.armigera and M.vitrata, respectively over control. Similarly, it has recorded xiv 83.78 and 78.57 % per cent reduction of pod damage due to H.armigera and M.vitrata, respectively over control. Whereas, NSKE 5% respectively recorded 70.76% and 75.82 % reduction of larval population of H.armigera and M.vitrata. Similarly, resulted in 64.85 and 61.89% reduction of pod damage over control. Furthur, higher grain yield with highest incremental cost benefit ratio (ICBR) was recorded in spinosad 45 % SC @ 73 g a.i/ha (1640kg/ha and 6.59, respectively ), followed by NSKE @ 5% ( 973 kg/ha and 6.52, repectively).
